General End User Information
The Strata DK Digital Business Telephone System is registered in accordance with the
provisions of Part 68 of the Federal Communications Commission’s Rules and
Regulations.

FCC Requirements
Means of Connection: The Federal Communications Commission (FCC) has
established rules which permit the Strata DK system to be connected directly to the
telephone network. Connection points are provided by the telephone company—
connections for this type of customer-provided equipment will not be provided on coin
lines. Connections to party lines are subject to state tariffs.
Incidence of Harm: If the system is malfunctioning, it may also be disrupting the
telephone network. The system should be disconnected until the problem can be
determined and repaired. If this is not done, the telephone company may temporarily
disconnect service. If possible, they will notify you in advance, but, if advance notice is
not practical, you will be notified as soon as possible. You will be informed of your
right to file a complaint with the FCC.
Service or Repair: For service or repair, contact your local Toshiba telecommunications
distributor. To obtain the nearest Toshiba telecommunications distributor in your area,
call Toshiba America Information Systems, Inc., Telecommunication Systems Division
in Irvine, CA (949) 583-3700.
Telephone Network Compatibility: The telephone company may make changes in its
facilities, equipment, operations, and procedures. If such changes affect the
compatibility or use of the Strata DK system, the telephone company will notify you in
advance to give you an opportunity to maintain uninterrupted service.
Notification of Telephone Company: Before connecting a Strata DK system to the
telephone network, the telephone company may request the following:
1. Your telephone number.
2. FCC registration number:
♦ Strata DK may be configured as a Key or Hybrid telephone system. The

appropriate configuration for your system is dependent upon your operation of
the system.
♦ If the operation of your system is only manual selection of outgoing lines, it may
be registered as a Key telephone system.
♦ If your operation requires automatic selection of outgoing lines, such as dial
access, Least Cost Routing, Pooled Line Buttons, etc., the system must be
registered as a Hybrid telephone system. In addition to the above, certain
features (tie Lines, Off-premises Stations, etc.) may also require Hybrid
telephone system registration in some areas.
♦ If you are unsure of your type of operation and/or the appropriate FCC
registration number, contact your local Toshiba telecommunications distributor
for assistance.
DK14 and DK40i
Key system: CJ6MLA-74479-KF-E
Hybrid: CJ6MLA-74478-MF-E
DK424
Hybrid: CJ69XA-10243-MF-E
Key system: CJ69XA-10242-KF-E
PBX: CJCHN-22757-PF-E
3. Ringer equivalence number: 0.3B. The ringer equivalence number (REN) is useful
to determine the quantity of devices which you may connect to your telephone line
and still have all of those devices ring when your number is called. In most areas,
but not all, the sum of the RENs of all devices connected to one line should not
exceed five (5.0B). To be certain of the number of devices you may connect to your
line, as determined by the REN, you should contact your local telephone company
to ascertain the maximum REN for your calling area.

4. Network connection information USOC jack required: RJ1CX, RJ2EX, RJ2GX,
RJ48C, RJ48X, RJ11, RJ14C, RJ21X (see Network Requirements in this
document). Items 2, 3 and 4 are also indicated on the equipment label.

Radio Frequency Interference
Warning: This equipment generates, uses, and can radiate radio frequency energy and if
not installed and used in accordance with the manufacturer’s instruction manual, may
cause interference to radio communications. It has been tested and found to comply
with the limits for a Class A computing device pursuant to Subpart J of Part 15 of FCC
Rules, which are designed to provide reasonable protection against such interference
when operated in a commercial environment. Operation of this equipment in a
residential area is likely to cause interference, in which case, the user, at his/her own
expense, will be required to take whatever measures may be required to correct the
interference.
This system is listed with Underwriters Laboratory.
UL Requirement: If wiring from any telephone exits the building or is
subject to lightning or other electrical surges, then secondary protection
is required. Secondary protection is also required on DID, OPS, and tie
lines. (Additional information is provided in this manual.)

In accordance with U.S. Copyright Law, a license may be required from
the American Society of Composers, Authors and Publishers, or other similar
organization, if radio or TV broadcasts are transmitted through the music-on-hold
feature of this telecommunication system. Toshiba America Information Systems, Inc.,
hereby disclaims any liability arising out of the failure to obtain such a license.
CP01, Issue 8, Part I Section 14.1
Notice: The Industry Canada label identifies certified equipment. This certification
means that the equipment meets certain telecommunications network protective,
operational and safety requirements as prescribed in the appropriate Terminal
Equipment Technical Requirements document(s). The Department does not guarantee
the Equipment will operate to the user’s satisfaction.
Before installing this equipment, users should ensure that it is permissible to be
connected to the facilities of the local telecommunications company. The equipment
must also be installed using an acceptable method of connection. The customer should
be aware that compliance with the above conditions may not prevent degradation of
service in some situations.
Repairs to certified equipment should be coordinated by a representative designated by
the supplier. Any repairs or alterations made by the user to this equipment, or
equipment malfunctions, may give the telecommunications company cause to request
the user to disconnect the equipment.
Users should ensure for their own protection that the electrical ground connections of
the power utility, telephone lines and internal metallic water pipe system, if present, are
connected together. This precaution may be particularly important in rural areas.

CAUTION!

Users should not attempt to make such connections themselves, but
should contact the appropriate electric inspection authority, or
electrician, as appropriate.

CP01, Issue 8, Part I Section 14.2
Notice: The Ringer Equivalence Number (REN) assigned to each terminal device
provides an indication of the maximum number of terminals allowed to be connected to
a telephone interface. The terminal on an interface may consist of any combination of
devices subject only to the requirement that the sum of the Ringer Equivalence
Numbers of all the Devices does not exceed 5.

DK14 Installation

DK14 Installation

This chapter explains how to install the Strata DK14 system. It includes information on site
requirements, wiring diagrams, and step-by-step instructions on how to install the unit(s), the
ground wiring, AC power cabling, reserve power (battery backup) cabling, and PCB cabling.

Inspection
1. When the system is received, examine all packages carefully and note any visible damage. If
any damage is found, do not open the packages. Contact the delivery carrier immediately and
make the proper claims.
2. After unpacking (and before installing), check the system against the packing list and inspect
all equipment for damage. If equipment is missing or damaged, contact your supplier
immediately.
3. Be sure to retain original packaging materials for re-use when storing or transporting system
hardware.

Packaging and Storage
CAUTION!

When handling (installing, removing, examining) PCBs, do not touch the back
(soldered) side or edge connector. Always hold the PCB by its edges.

➤ When packaging and storing the system, remove PCBs from the system cabinet (the power
supply may remain installed in the cabinet for storage and shipment). PCBs should be
packaged in their original antistatic bags for protection against electrostatic discharge. Be sure
to package equipment in its original shipping containers.

Site Requirements
This section defines the installation site requirements necessary to ensure a proper operating
environment for the DK14. Also included are grounding requirements. (Table 1-1 for electrical/
environmental characteristics.)

Strata DK I&M

5/99

1-1

DK14 Installation
Site Requirements

Input Power
The system requires an input power source of 115VAC ± 10VAC, 50/60 Hz, 10 amps. The AC
outlet is recommended to be dedicated and unswitched, with a solid third-wire ground. (See “AC
Power and Grounding Requirements” on Page 1-3 for details).
This is to eliminate interference from branch circuit motor noise or the like, and to prevent
accidental power-off. To avoid accidental power turn-off, Toshiba recommends that you do not use
an ON/OFF wall switch on this dedicated AC circuit.
For the DK14, a reserve power source (two customer-supplied 12-volt batteries) may be connected
to the system to serve as a power failure backup.

Clearance and Location

AC Power and Grounding Requirements
The DK14 requires a solid earth ground
for proper operation. The AC power cord
contains a conductor for the “third-wire
ground” provided by the commercial
power outlet.
The third-wire ground should be the only
ground necessary for the DK14; this
ground must originate at the buildings
main power distribution panel and have a
solid connection to earth ground. (See
Figure 1-2.)

AC Power and Grounding Requirements

AC Power and Third-wire Ground Test
Test the “third-wire ground” for continuity by either measuring the resistance between the third
prong terminal (earth ground) and a metal cold water pipe (maximum: 1 ohm), or by using a
commercially available earth ground indicator. If neither procedure is possible, perform the
following earth ground test procedure.
WARNING! Hazardous voltages that may cause death or injury are exposed during the
following test. Use great care when working with AC power line voltage.

➤ To perform the earth ground test procedure
1. Obtain a suitable voltmeter, and set it for a possible reading of up to 250VAC.
2. Connect the meter probes between the two main AC voltage terminals (white and black wires)
on the wall outlet. The reading obtained should be between 100~125VAC.
3. Move one of the meter probes to the third terminal (green wire ground). Either the same
reading or a reading of zero volts should be obtained.
4. If the reading is zero volts, leave one probe on the ground terminal and move the other probe
to the second voltage terminal.
CAUTION!

If a reading of zero volts is obtained on both voltage terminals (white wire to
green wire, black wire to green wire), the outlet is not properly grounded. Omit
Steps 5 and 6, and see following CAUTION!

5. If a reading of zero volts on one terminal, and a reading of 105~125VAC on the other terminal
is obtained, remove both probes from the outlet.
6. Set the meter to the “OHMS/Rx1” scale. Place one probe on the ground terminal, and the other
probe on the terminal that produced a reading of zero volts. The reading should be less than 1
ohm.
CAUTION!

If the reading is more than one ohm, then the outlet is not adequately grounded.
If the above tests show the outlet AC voltage is not in range or is not properly
grounded, the condition should be corrected (per Article 250 of the National
Electrical Code) by a qualified electrician before the system is connected.

Alternate or Additional Ground
If the “third-wire” AC ground can not practically be improved or if extreme motor noise or other
disturbance causes system malfunction, or if local area lightning storms exist, a separate direct
ground may be warranted.
Connect a separate earth ground from a cold water pipe or earth grounding rod directly to the FG
screw terminal on the DK14 power supply (see Figure 1-2).
This chapter provides the instructions necessary to mount the DK14 Key Service Unit (KSU).
Instructions are also provided on how to remove and replace the power supply.

DK14 Installation
Printed Circuit Board (PCB) Installation

Printed Circuit Board (PCB) Installation
This section provides procedures for installation of Strata DK14 system optional printed circuit
boards (PCBs) into the KSU. This includes installation instructions, optional configuration
information, and wiring and programming considerations for each PCB.
Be sure the ground has been checked. (See “AC Power and Grounding Requirements” on Page
1-3.)

PCB Installation Considerations
The Strata DK14 KSU comes standard with four digital telephone circuits (ports) and two CO line
circuits. These circuits, along with the common control unit, are built into the motherboard.

KSU Option PCBs
The DK14 KSU can support up to four optional PCBs, including:
♦

A maximum of two QCDU2s: each one provides one CO line circuit and two digital telephone
circuits.

♦

A QSTU2 which provides two standard telephone circuits (ports).

♦

A QRCU2 which provides three circuits to receive DTMF tones (required for DISA and
devices connected to QSTU2s), and three circuits to detect busy tone (required for the ABR
feature).

♦

A WSIU which provides a port for either a Station Message Detail Recording (SMDR) device
or a maintenance terminal or modem, or Caller ID interface.

♦

The KSU does not come from the factory with any option PCBs installed. Each of the option
PCBs must be installed in specific locations. (See Figure 1-9.)

PCB Option Considerations
PCBs may be configured for a variety of hardware and software options. Hardware options are
defined as either internal (generally related to optional PCB subassemblies) or external (related to
connection of peripheral equipment such as background music, voice mail, etc.). Hardware and

Older Version(s): QCDU1A

QCDU2 Configuration
The QCDU2 may have to be configured to control excessive loudness if the system is close to a
CO or installed behind a PBX telephone system. It does not have to be configured for anything
else. The decibel (db) PAD switch, SW101 controls the loudness by providing a 3 db signal level
drop to, or from, the PBX or CO when set to the PAD position. The switch comes from the factory
set at 0 (for no PAD) meaning no PAD loss.

QCDU2 Installation
A maximum of two QCDU2 PCBs can be installed in the KSU.
➤ To install the QCDU2
1. If the system is located within one mile of the CO or PBX telephone system, set db PAD
switch SW101 to the PAD position.
2. Make sure that the power supply switch is OFF.
3. Slide QCDU2’s front edge and FG wire under the System Frame Ground Bar; align and insert
the QCDU2 connector J1 into the motherboard connector (J9 for CO3 first, J10 for CO4
second). (See Figure 1-10)
Apply firm, even pressure to ensure proper
mating of the connectors. Make sure the
QCDU2’s connector edge next to the connector
J1 snaps firmly into the standoffs on the KSU
motherboard. (See Figure 1-4).
4. Connect the Frame Ground (FG) lead from the
QCDU2 to the screw nearest the QCDU2
located on the system Frame Ground bar.
Remove the “knock-out” from the KSU cover
CO3 or CO4 access slot, and store the “knockout” in the slots provided in the KSU base. (See
Figure 1-11.)

DK40i Configuration

This chapter explains how to configure a Strata DK40i system. It also provides tables for recording
the hardware and station devices that make up the system.

Base Key Service Unit (KSU)
Station and CO Lines
The DK40i Base KSU comes equipped with eight digital telephone station circuits. One of three
optional PCBs can be added to provide either four loop start or DID lines, or two ISDN BRI S/T
circuits (Table 2-1). An optional TCIU2 Printed Circuit Board (PCB) can be added to the Base
KSU loop start line PCB to provide Caller ID interface. An optional KSTU2 PCB can be added to
provide four standard telephone circuits (ports).
An Expansion KSU can be added to the DK40i to increase the system capacity to 28
station ports and 12 lines.

Note

Peripherals
The DK40i Base KSU can support a number of peripherals, which are not considered as stations or
lines and do not affect the maximum station and line capacities. The DK40i Base KSU comes
standard with built-in interfaces for connecting the following dealer-supplied equipment: an
amplifier and speaker for paging and night ringing, Music-on-Hold (MOH) source, reserve power
batteries, and emergency standard telephone for system power failure occurrences when using
loop start lines in the base cabinet.
A relay contact is also provided to control one of the following peripherals: MOH source, night
bell, or page amplifier mute control.
An optional KSTU2 PCB provides an alternate background music source interface. The music
plays through Toshiba telephone speakers, as opposed to the external page speakers.
The optional TSIU PCB provides two RS-232 interface ports to connect two of three options: a
DKAdmin PC (or external modem for remote maintenance); or VM SMDI; or an SMDR port to
connect a call accounting device or printer. An Expansion Unit RS-232 interface PCB is required
if all three features are needed.

Station Considerations

Station Considerations
For configuration purposes, any device which is connected to a dedicated telephone circuit is
considered a “station.” Although the words “telephone” and “station” are often used
interchangeably in Strata DK40i documentation, devices other than telephones—such as Standalone Data Interface units (PDIU-DSs)—should also be considered stations when configuring a
system since they require a dedicated telephone circuit. A station apparatus overview is shown in
Table 2-8.

PDKU2 can each support PDIU-DSs/RPCI-DI, while only
circuits 1~7 on a PDKU21 can support PDIU-DSs/RPCI-DIs.

Each electronic telephone circuit can support an electronic
telephone.

Electronic Direct Station Selection
Console (HDSS)

2

The system supports only one HDSS console. The console must
be connected to both circuits 7 and 8 on the PEKU. The PESU will
not support an HDSS console.

Alternate BGM source

1

The system supports an alternate BGM source which can be
heard over digital and electronic telephone and external page
speakers. This source can be connected to either circuit 3 on a
PEKU, circuit 8 on a PESU, or circuit 4 on a KSTU2 or PSTU PCB.

Conference amplifier

2

Up to three amplifiers for two CO line conferencing can be
connected to ports 9 and 10; 17 and 18; and 24 and 25 on a PEKU
or PESU.

CAUTION!

You must always calculate the Power Factor (PF)—see Worksheet 2. Exceeding
the PF will cause the power supply to fail. If PF is exceeded, replace EKTs with
DKTs.

Standard Telephone Circuit Options
In addition to supporting standard telephones, each of the standard telephone circuits can support
any one of a number of single-wire-pair devices, including voice mail/Auto Attendant devices and
modems (see Table 2-11).

Configuration Considerations

Configuration Considerations
The following considerations should be taken into account when filling out the tables in
“Worksheet 1 – System PCB Assignment Guide”.

Base Cabinet
1. Only one line PCB (TCOU, TDDU, or TBSU) can be installed in the Base cabinet.
2. If TBSU is installed, each circuit can be configured independently as a station side or line
side S/T BRI circuit.
3. Each TBSU ISDN BRI circuit uses two station ports and no line numbers if the circuit is
configured for the station side.
4. Each TBSU ISDN BRI circuit will use two line numbers and no station ports if the circuit is
configured for the line side.
5. TDDU provides four DID lines and does not use station ports.
6. Install TCIU2 for Base KSU CO (TCOU) Caller ID Lines.
CAUTION!

To prevent system malfunction, do not install TCIU1 in the DK40i system.

7. K5RCU, K5RCU2 or K4RCU3 must be installed when using built-in automated attendant,
Voice Mail, ABR, Stratagy DK, standard telephone ports, Tie lines, DISA, or DID Lines.
8. TSIU can be used for an RS-232 Maintenance (TTY) port, SMDI or SMDR port. RSIU cannot
be used.

Expansion Cabinet
1. Each RDDU provides four DID lines and does not use station ports. This is different from the
DK424, DK40 and DK16e in which each DID circuit used a line number and station port.
2. Each REMU to PEMU provides the four Tie lines and does not use station ports. This is
different from the DK424, DK40, and DK16e in which each Tie line circuit used a line
number and station port.
3. Stratagy DK can be installed in the expansion unit to provide two, four, six or eight built-in
Automated Attendant/Voice Mail circuits. Always install Stratagy DK in slot 15, 16, or 17; do
not install Stratagy DK in slot 18. Program the Stratagy VM ports as if they were standard
telephone ports connected to an external VM device. All models of Stratagy DK use up eight
station ports.
4. Install RCIU2/RCIS in slot 17 (only) for Expansion KSU (RCOU/RCOS or RGLU2) Caller
ID Lines.
CAUTION!

To prevent system malfunction, do no install RCIU1 in DK40i, and RCIU2
must not be installed in slot 18.

5. If required, install PIOU, PIOUS, and RSSU in any slot.
6. Speaker OCA and RPCI/DIU data applications can only be installed on digital telephone ports
in the DK40i Base KSU and slots 15 and 16 of the DK40i Expansion KSU (24 maximum).

2-14

Strata DK I&M

5/99

DK40i Configuration
Configuration Considerations

7. Each Tie or DID line PCB installed provides four Tie or DID lines and does not use four
station ports as in the DK40 (PEMU, REMU, RDDU, and RDDU).
8. RWIU can be installed in any of the expansion cabinet slots (15, 16, 17, and 18) to support up
to 8 StrataLink handsets. If there are 9 to 16 handsets, the RWIU must be installed in slot 15
and slot 16 must be vacant. This system cannot support 24 or 32 handsets because of a port
limitation.

DK40i ISDN
1. TBSU installs in the base cabinet to provide 2 BRI S/T circuits, each circuit can be station side
or line side in any combination.
2. If a TBSU is installed, TDDU or TCOU cannot be installed. Only one PCB (TSBU, TCOU or
TDDU) can be installed in the DK40i base cabinet for a given DK40i configuration.
3. RBSU installs in any expansion unit slot to provide 2 BRI S/T circuits which can be station
side or line side in any combination.

DK40i Configuration

Configure DK40i, ISDN BRI PCBs (RBSU, RBSS and TBSU) with the following rules

4. RBSS installs on an RBSU in any expansion unit slot to provide 2 BRI S/T circuits, which can
be station side only.
5. Each RBSU, RBSS and TBSU ISDN BRI circuit uses two station ports and no line numbers if
the circuit is configured for station side. This is different from the DK424 ISDN in which each
BRI circuit uses two station ports and two line numbers when the circuit is configured for
station side.
6. Each RBSU and TBSU ISDN BRI circuit will use two line numbers and no station ports if the
circuit is configured for the line side. This is different from DK424 ISDN, in which each BRI
circuit uses two station ports and two line numbers when the circuit is configured for line side.
7. Total maximum BRI S/T circuits on the station side is 10 (20 ports/B-channels max.).
8. Total maximum BRI S/T circuits on the CO line side is 6 (12 lines/B-channels max.).

DK40i Configuration
Worksheet 2 – System Power Factor Check

Worksheet 2 – System Power Factor Check
The DK power supply was engineered for maximum cost efficiency to provide power for the most
configurations. Because of this design, some power limitations exist when using old electronictype telephones, telephone option hardware, or newer PCBs, such as RWIU, TBSU, RBSU/RBSS.

Telephone/Device PFs
The power supply of each KSU supplies a limited amount of power. For each KSU, calculate the
total Telephone/Device Power Factor (PF) and add it to Table 2-23. (See Table 2-12 for PCB
quantity and type.)
The TBSU, RBSU/RBSS and RWIU PCBs require more power from +5VDC than other PCBs;
therefore, it is necessary to calculate the +5VDC and -24VDC PF on DK40i.
Important!

Table 2-21

A system PF check must be performed for all configurations. See Table 2-21 for the
power supply +5VDC and -24VDC PFs for the DK40i system.

DK16/DK16e/DK40/DK40i Component Compatibility

DK16/DK16e/DK40/DK40i Component Compatibility
The Strata DK16 Base KSU cannot be upgraded to a DK16e, DK40 or DK40i and the DK16
Expansion Cabinet is not compatible with the DK16e, DK40 or DK40i. The Strata DK40i is not a
modification of the DK40, but rather a completely new system.
The DK40i uses the DK40 expansion cabinet. The DK16e can be upgraded to DK40 by changing
a ROM chip, but not to a DK40i. The DK40 base cabinet cannot be upgraded to a DK40i.

Most DK16 PCBs are not compatible with the DK40i, including the four-port Standard Station
Interface Unit (KSTU1A), four-circuit DTMF/ABR Tone Detection Receiver Unit (K4RCU1A or
K4RCU2A), and the Auto Attendant feature cartridge (KFCU1A).
Four of the Strata DK40i PCBs are backward compatible with the DK16, DK16e and DK40. They
are: KSTU2A, K4RCU3A, K5RCU and K5RCU2. The DK40i Expansion Cabinet is also
backward compatible with the DK16.

DK40i Configuration

The original DK16 two-loop start CO line and four-digital station interface unit (KCDU1A) is
forward compatible with the DK16e or DK40i.

This chapter explains how to install the Strata DK40i system. It includes information on site
requirements, wiring diagrams, and step-by-step instructions on how to install the unit(s), the
ground wiring, AC power cabling, reserve power (battery backup) cabling, and PCB cabling.

1. When the system is received, examine all packages carefully and note any visible damage. If
any damage is found, do not open the packages. Contact the delivery carrier immediately and
make the proper claims.
2. After unpacking (and before installing), check the system against the packing list and inspect
all equipment for damage. If equipment is missing or damaged, contact your supplier
immediately.

3. Be sure to retain original packaging materials for re-use when storing or transporting system
hardware.

Packaging and Storage
CAUTION!

When handling (installing, removing, examining) PCBs, do not touch the back
(soldered) side or edge connector. Always hold the PCB by its edges.

➤ When packaging and storing the system, remove PCBs from the system cabinet (the power
supply may remain installed in the cabinet for storage and shipment). PCBs should be
packaged in their original antistatic bags for protection against electrostatic discharge. Be sure
to package equipment in its original shipping containers.

Site Requirements
This section defines the installation site requirements necessary to ensure a proper operating
environment for the DK40i. Also included are grounding requirements.

DK40i Installation
Site Requirements

Input Power
The system requires an input power source of 115VAC ± 10VAC, 50/60 Hz, 15 amps. The AC
outlet is recommended to be dedicated and unswitched, with a solid third-wire ground. (See “AC
Power and Grounding Requirements” on Page 3-4.)
This eliminates interference from branch circuit motor noise or the like, and to prevent accidental
power-off. To avoid accidental power turn-off, Toshiba recommends that you do not use an ON/
OFF wall switch on this dedicated AC circuit.
For the Strata DK40i, a reserve power source (two customer-supplied 12-volt batteries) may be
connected to the system to serve as a power failure backup.

Clearance and Location
The minimum clearance requirements for the Strata DK40i Base and Expansion KSUs are shown
in Figures 3-1 and 3-2. Refer to Page 3-5 for DK40i KSU mounting instructions.

AC Power and Grounding Requirements

AC Power and Grounding Requirements
The DK40i requires a solid earth ground for proper operation.
The AC power cord contains a conductor
for the “third-wire ground” provided by
the commercial power outlet. The thirdwire ground should be the only ground
necessary for the DK40i; this ground
must originate at the buildings main
power distribution panel and have a solid
connection to earth ground. (See Figure
3-3.)
CAUTION!

Lack of proper ground
may cause improper
operation and, in extreme
cases, system failure.

Test

Figure 3-3

DK40i Grounding Diagram

Test the “third-wire ground” for continuity by either measuring the resistance between the third
prong terminal (earth ground) and a metal cold water pipe (maximum: 1 ohm), or by using a
commercially available earth ground indicator. If neither procedure is possible, perform the
following earth ground test procedure.
WARNING! Hazardous voltages that may cause death or injury are exposed during
the following test. Use great care when working with AC power line
voltage.

➤ To perform the earth ground test procedure
1. Obtain a suitable voltmeter, and set it for a possible reading of up to 250VAC.
2. Connect the meter probes between the two main AC voltage terminals (white and black wires)
on the wall outlet. The reading obtained should be between 100~125VAC.
3. Move one of the meter probes to the third terminal (green wire ground). Either the same
reading or a reading of zero volts should be obtained.
4. If the reading is zero volts, leave one probe on the ground terminal and move the other probe
to the second voltage terminal.
CAUTION!

If a reading of zero volts is obtained on both voltage terminals (white wire to
green wire, black wire to green wire), the outlet is not properly grounded. Omit
Steps 5 and 6, and see following CAUTION!

5. If a reading of zero volts on one terminal, and a reading of 100~125VAC on the other terminal
is obtained, remove both probes from the outlet.

3-4

Strata DK I&M

5/99

DK40i Installation
KSU Mounting Considerations

6. Set the meter to the “OHMS/Rx1” scale. Place one probe on the ground terminal, and the other
probe on the terminal that produced a reading of zero volts. The reading should be less than 1
ohm.
CAUTION!

If the reading is more than one ohm, then the outlet is not adequately grounded.
If the above tests show the outlet AC voltage is not in range or is not properly
grounded, the condition should be corrected (per Article 250 of the National
Electrical Code) by a qualified electrician before the system is connected.

Alternate or Additional Ground
If the “third-wire” AC ground can not practically be improved or if extreme motor noise or other
disturbance causes system malfunction, or if local area lightning storms exist, a separate direct
ground may be warranted.
Connect a separate earth ground from a cold water pipe or earth grounding rod directly to the FG
screw terminal on the DK40i power supply (see Figure 3-3).

The Base KSU and the optional Expansion KSU are both designed to be mounted on a wall or
other vertical surface. Toshiba recommends using method 1 or 2 (see Figure 3-4).

DK40i Installation

KSU Mounting Considerations

Prior to Installation
1. Loosen the screws on the front cover and the side cover of the Base KSU, remove the covers
(see Figure 3-5). Figure 3-6 on Page 3-11 details the interior.
2. Place the BATT jumper plug to the ON position.
3. Install a CO line board, either the TDDU or TCOU onto the TMAU board (see Figure 3-7).
The TCOU provides four loop start CO lines and can accommodate the Caller ID interface
unit.
The TDDU provides four DID lines.
4. Set CO line card switches.
TCOU: Set the TCOU PAD switches (SW400-SW475) to the appropriate position (see Figure
3-21 on Page 3-32). The factory setting is NORMAL. If CO lines are connected to a PBX or
are in close proximity to the central office the PAD position may be required.
TDDU: Set the TDDU PAD switches to the appropriate position. Also, set the high/low
voltage jumper plugs as required for proper dial pulse operation. See Figure 3-22 on Page 335.
5. If you are not installing a TCIU2, skip to Step 6. To install the TCIU2 (see Figure 3-20 on
Page 3-29), align the prongs P20, P21, and P22 over P120, P121, and P122 of the TCOU and
gently press down. Slip the plastic stand-off hook through the hole.
CAUTION!

Strata DK I&M

5/99

To prevent system malfunction, DO NOT install TCIU1 in the DK40i system.

3-5

DK40i Installation
KSU Mounting Considerations

6. The TCOU or TDDU cards have a green and yellow wire with a two-prong spade on the end.
Slip the spade under the second screw from the right on the power supply (see Figure 3-7).
7. If applicable, install KSTU2 Standard Telephone Interface Unit. The KSTS2 comes preinstalled onto the KSTU2. Then install both boards into the DK40i Base KSU (see Figures
3-17~3-19, beginning on Page 3-26).
8. If applicable, install the K5RCU or K5RCU2 or K4RCU3 (which provides Automatic Busy
Redial and DTMF tone detection) into the Base KSU (see “K4RCU, K5RCU or K5RCU2
Installation” on Page 3-23).
9. If applicable, install the KKYS (which provides built-in Auto Attendant) onto the K5RCU or
K5RCU2 or K4RCU3.
10. If applicable, install the TSIU Serial Interface PCB into the KSU (Figure 3-23 on Page 3-37).
If the TSIU is used for SMDR or TTY, then the PIOU/PIOUS SMDR/TTY output is not
active.

Testing the System’s Power Supply
If the “AC” or “DC” LEDs fail to light in Steps 1 or 3, see TPSU16 Circuit Breaker Reset
Procedure–Case 1.
1. Plug the AC power cable into an outlet (see Figure 3-8). The “AC” LED on the power supply
lights green.
2. Turn ON the DC power switch for the TPSU16 power supply (see Figure 3-6). The “DC” LED
on the power supply lights green.
3. Using a voltmeter or other device which checks voltage, measure the voltages referenced to
frame ground (FG) at the P16 connector pins (test points) located on the motherboard. The
voltages should fall within the ranges below.
♦

Yellow-green, black, and green wires: 0V

♦

Two yellow wires: -27V

♦

Range: -25.94V~-28.66V

If the voltages do not fall within the ranges, unplug the DC power pins from the P16 connector
and measure again at the same location; if the ranges remain unacceptable. See TPSU16
Circuit Breaker Reset Procedure–Case 2.

DK40i Installation
KSU Mounting Considerations

TPSU16 Circuit Breaker Reset Procedure
Case 1
If the AC and DC LEDs on the TPSU16 power supply in the Strata DK40i Base KSU do not light,
even though the AC power plug is inserted into the wall outlet and the TPSU16 DC power switch
is turned on, the AC overvoltage circuit breaker may have opened.
➤ To reset the AC overvoltage circuit breaker
1. Remove the AC power plug from the wall outlet, turn the DC power switch OFF, and wait six
minutes.
2. After six minutes, insert the AC plug back into the wall outlet and turn the DC power switch
ON. The AC and DC LEDs should turn on and the system should operate.
If the system fails to operate, either the wall outlet is not providing AC power or the system’s
power supply is defective.
3. If the AC power checks good, replace the power supply (see “Power Supply Removal and
Replacement” on Page 3-19).

If the TPSU16 power supply AC and DC LEDs light, but the system does not operate, the TPSU16
DC output overcurrent circuit breaker may have opened because of a DC short circuit.
➤ To reset the DC output overcurrent circuit breaker
1. Turn the DC power switch OFF for 15 seconds and then turn it back on. The system will go
back to normal operation if the overcurrent breaker resets.

DK40i Installation

Case 2

2. If the system continues to fail, press in the two -24VDC circuit breakers located on the bottom
left corner of the TPSU16 power supply.
If, then, the system does not return to normal operation, the TPSU16 power supply may be
defective or an optional PCB may be shorting out the TPSU16.
3. Remove all optional PCBs and the Expansion KSU to locate the short, then repeat Steps 1 and
2 and perform the power supply test.
4. If the power supply fails the test, replace the power supply (see “Power Supply Removal and
Replacement” on Page 3-19 for more information.). If the power supply passes the test, the
DK40i Base KSU is probably defective.

12VDC battery. Connect the black lead to the open negative terminal of the second 12VDC
battery.
Important!

The KSU must be connected to the live operating (hot) AC power source, and the
power supply ON/OFF switch set to ON prior to the final step of connecting the
reserve power batteries to the power supply via the BATT +/- receptacle. If the
batteries are connected after AC power is lost, reserve power will not function.

4. Connect the PBTC-3M battery cable two-prong male plug to the power supply BATT +/receptacle.
5. To test reserve power operation, disconnect the system AC power plug with the power supply
power ON/OFF switch in the ON position. The system should continue to operate without any
interruption.
6. Plug the AC power cable into PN2.
7. Plug the AC power cable into an outlet and turn ON the power supply switch.
8. See “Prior to Installation” to confirm that the power supply is working properly.
9. Plug reserve battery cable into BATT connector of power supply.

Power Failure Emergency Transfer Option
To enable this option, a dedicated standard telephone must be connected to the Power Failure
Transfer Interface (PF1) of a DK40i Base KSU equipped with a TCOU.
Note

During normal operation, this telephone cannot be used and does not count as a station
(does not reduce the number of system’s available stations).

If there is a power failure, the telephone automatically is connected to CO Line 1. When power is
restored, the system resumes normal station and CO line assignments, and the dedicated telephone
becomes inoperative again.
Important!

This is not available on a DK40i system with a TDDU installed.

Installing Power Failure Emergency Transfer
➤ Connect a standard telephone to the PF1 connector in the Base KSU (see Figure 3-13).

Testing Power Failure Emergency Transfer
1. Turn the system power switch OFF.
2. Lift the emergency standard telephone handset, and verify that there is CO dial tone.

Expansion KSU PCBs
A DK40i Expansion KSU from the factory does not come with any PCBs installed. (See Table 2-3
on Page 2-3 for a list of PCBs supported by the DK40i Expansion KSU and Chapter 7 – DK40i/
DK424 Universal Slot PCBs for detailed descriptions/installation instructions.) Toshiba
recommends that PCBs which support electronic, digital or wireless telephones be installed into
slots 15 and 16 because slots 17 and 18 cannot support speaker Off-hook Call Announce (OCA) or
Data Interface Units (DIUs) or more than 8 wireless handsets. See “Base/Expansion KSU
Compatibility” beginning on Page 2-3 for configuration information for DK40i PCBs.

PCB Hardware/Software Options
PCBs can be configured for a variety of hardware and software options. Hardware options are
defined as either internal (generally related to optional PCB subassemblies) or external (related to
connection of peripheral equipment, such as background music, voice mail, etc.). Hardware and
software options for each PCB are identified in the individual PCB installation procedures in this
chapter.
PCB Hardware Options
Each PCB must be configured for the applicable hardware options prior to installation of the PCB.
Configuration instructions for internal hardware options are provided in the individual PCB
installation procedures in this chapter and Chapter 8 – DK40i/DK424 Universal Slot PCB Wiring.
Configuration instructions for external hardware options are provided in Chapter 10 – Peripheral
Installation.
PCB Software Options
After installation of the PCBs in the KSU, configure the PCBs for software options through
programming. A programming overview for each PCB is provided in this chapter. Refer to the
Strata DK Programming Manual for more detailed programming instructions.

PCB Installation/Power Supply Considerations
WARNING! To avoid electrical shock, make sure that the power supply is OFF whenever
removing or installing PCBs.

Before installing any PCBs, make sure the power supply has been tested, and the ground has been
checked. (See “AC Power and Grounding Requirements” on Page 3-4.)

PCB Wiring
See “MDF Wiring Diagrams” on Page 3-41 in this chapter for DK40i Base KSU wiring and
Chapter 8 – DK40i/DK424 Universal Slot PCB Wiring for Expansion KSU wiring. See Chapter 16
– Strata AirLink Systems for RWIU wiring.

Digital Telephone Circuits
The eight digital telephone circuits that come standard with the system are integrated into the
DK40i motherboard in the Base KSU. These circuits are identical to the digital circuits found on
the PDKU. The motherboard does not have to be configured for the digital circuits to operate. For

Note

KSTU2 Configuration
The KSTU2 hardware has to be configured only for the square wave ring generator voltage level,
nothing else.

DK40i Installation

For the system to recognize the Dual-Tone Multi-Frequency (DTMF) tones generated by
standard telephones (or any other device connected to a KSTU2 port), a K4RCU3 must be
installed in the Base KSU.

KSTU2 Installation
1. Make sure that the power supply switch is OFF.
2. Before installing the KSTU2 in the Base KSU, set the SW1 ring generator to 130V P-P or
190V P-P.
Note

Most standard telephones and two-wire devices require 190; however, some devices may
experience ring-trip at 190, and should be set at 130.

3. Plug the KSTU2 cable into the P4 connector on the motherboard in the Base KSU. The red
wire on the cable should match up with pin 1 on the lower side of the connector.
4. Plug the KSTU2 P508 female connector into the P8 male connector on the motherboard.
5. Secure the KSTU2 to the standoffs with the two provided screws.

KSTU2 Wiring
Refer to DK40i Base KSU KSTU2 wiring in Figure 3-25 on Page 3-41.
The KSTU2 must be connected to a OL13A (or equivalent) type lines for off-premises stations
(300 ohms loop resistance max., including the telephone or other devices DC off hook resistance).

KSTU2 Programming
Program 03: Specify code 31 for KSTU2 slot.
Program 31: Configures all KSTU2 ports connected to voice mail (see Chapter 8 – DK40i/DK424

loop start CO lines

Older Version(s): none

To receive Caller ID, a TCIU2 circuit must be available to each line. (See Figure 3-20.)
CAUTION!

To prevent system malfunction, do not install TCIU1 in the DK40i system.

Each TCIU2 Caller ID circuit has a two-wire tip/ring interface which must be bridge-wired across
its corresponding ground or loop start CO line tip/ring. This is done automatically by the PCB
connectors when the TCIU2 is mounted on the TCOU. However, if installing an RCOU/RCIU2 in
the Expansion KSU, the connection is made on the Main Distribution Frame (MDF). See the
RCIU wiring diagram in Chapter 8 – DK40i/DK424 Universal Slot PCB Wiring.

TCIU2 Installation
1. Turn power OFF.
2. Install the TCIU2 onto the TCOU PCB by aligning the three sets of connectors marked TCOU
or TCIU2, depending on the card.
3. Press down evenly and firmly on the TCIU2 card.

TCIU2 Programming
Program 03: Automatically assigns TCIU2 (Caller ID circuit) to slot 14 (code 81) when the TCIU2
is installed and power is turned on.
Note

TCIU2 Caller ID circuits are numbered automatically in numerical order starting from
01~04 when the TCIU2 is installed. Slots with code 81 will increment the Caller ID circuit
numbers by four circuits on the DK40i.

Program *50: Assigns TCOU lines that will receive Caller ID to the associated TCIU2 Caller ID
circuit number. TCIU2 circuits 1~4 must be assigned to TCOU circuits 1~4, respectively. RCIU
circuits 5~8 should be assigned RCOU or RGLU circuits 5~8.
After assigning CO lines to Caller ID circuits, turn system power OFF for approximately five
seconds and then back on or run Program 91-2 to activate Program *50 assignments.
Program *51: Sets the Caller ID (CLID)/Automatic Dialed Number Identification (ANI) memory
allocation for the appropriate stations. This memory is used to save CLID/ANI telephone numbers
for calls that are received but not answered (abandoned calls). CLID/ANI numbers are not saved in
station memory if they are answered. Stations can be allocated with memory to save up to 100
numbers in 10-number increments.
The total memory allocated to all stations in a system is 200 numbers.

Printed Circuit Board (PCB) Installation

Note

When a CO line rings multiple stations, a station must be the owner of the Caller ID or
ANI CO line to be able to save abandoned call (Caller ID and/or ANI) telephone numbers.
(See Program *52.)

Program *52: Assigns stations as owners of Caller ID CO lines. These stations will store the Caller
ID telephone numbers received on abandoned (not answered) calls for the lines which they own.
Typically all common CO lines are assigned to one designated telephone or attendant console and
private lines are assigned to individual private line telephones.
Note

A station must also be allocated with Caller ID/ANI storage memory in Program *51 to
store abandoned call telephone numbers.

Program 39, Code 462: Assigns the Caller ID/ANI Lost Call Auto Dial button to LCD telephones
that store Caller ID and/or ANI abandoned call telephone numbers. A user can scroll through the
stored abandoned call phone numbers and auto dial the selected number using this button.

pulsing at different loop lengths. If close to the CO, the sensitivity should be set to low (L). As
the loop length increases, set it to high (H).
6. Insert the TDDU into the appropriate slot and apply firm, even pressure to ensure proper
mating of connectors.

TDDU Programming
Program 03: Specify Code 16 for slots that will support TDDUs. Make sure DTMF operation is
enabled.
Note

Program 03 can be skipped and Program 91 run instead.

Program *09: Assigns DID line extensions to route to station [PDNs].
Program 10-1: Enables or disables Two-line Conference.

DK40i Installation
Printed Circuit Board (PCB) Installation

TSIU
Serial Interface Board
System:

DK40i Base KSU (plugs into KSU main PCB)

Circuits per PCB: two TTY/RS-232 interface ports
Interfaces with:

SMDR connection for call accounting device
customer-provided external modem for local/remote maintenance from a PC with
DK Admin

Older Version(s): none

The TSIU PCB enables the DK40i system to connect to various hardware devices. It does not have
an internal modem and does not support IMDU. (See Figure 3-23.)
Only one TSIU can be installed per DK40i system. When installed, the TSIU port functions are
identified and enabled automatically when power is turned on and the PIOU can still be installed
for zone paging. Port 01 is TTY (Program 76-1, code 1) and Port 02 is disabled (Program 76-1,
code 0). If the same function is programmed for an TSIU port and a PIOU or PIOUS port, only the
TSIU port functions.
The communication parameters for all TSIU TTY ports are:
♦

Data word bits = 7

♦

Parity = even

♦

Stop bits = 1

The communication parameters for a TSIU SMDR port is:
♦

Data word bits = 8

♦

Parity = none

♦

Stop bits = 1

TSIU Installation
➤ See Figure 3-23 for installation.

TSIU Programming
Program 03: No assignment is necessary. TSIU is automatically enabled when installed and power
is turned ON. It is not assigned to a slot.
Program 76-1X-Y: Assigns each installed TSIU port to a function. Where X identifies the TSIU
port number (1~4) and Y identifies the TSIU port function:
♦

Y=1, RS-232 TTY (Program 77-1, LED 14 OFF)

♦

Y=2, SMDR

♦

Y=4, SMDI

♦

Y=0, No function - this should be used for any TSIU ports that are not used.

Note

3-36

Function codes set in Program 76-1X-Y override PIOU and/or PIOUS function codes 41
set in Program 03.

Strata DK I&M

5/99

DK40i Installation

Program 76-2X-Z: Assigns each installed TSIU port to operate at a specified transmission rate.
Where X identifies the TSIU Port number (1, 2). Z identifies the TSIU/port transmission rate in
bits-per-second (bps):
♦

Z=1; 9600

♦

Z=2; 4800

DK424 Configuration

4

This chapter explains how to configure the Strata DK424 system. The system has a modular
design which enables it to support a number of station and CO line configurations. The main
component of the system is the common control unit (RCTU) Printed Circuit Board (PCB).
The focus of this chapter is a series of worksheets, providing a systematic procedure for
determining the system’s size. The worksheets also provide space to record the hardware and
station devices that make up the system. Tables and example worksheets are included to assist you
in filling out the worksheets.
Important!

Prior to Release 4, Tie and DID lines used station ports. With Release 4.0 and
higher processors, these lines do not use station ports, allowing larger capacity
systems when Tie and DID lines are required.

Important!

System Configuration can be complex and time consuming. For best results:
♦

Use DKQuote to provide easy, fast, automated configuration. It runs on an IBM-compatible
Pentium® PC or higher, equipped with a 110MB or larger hard drive, a 3.5” 1.44 MB high
density floppy disk drive, 16MB RAM, and Windows® 98/95 or Windows NT®. See the
DKQuote User Guide for more information.

♦

If the above software is not available, use the Worksheets in this chapter.

DK424 Configuration

System Configuration

The DK424’s main components are: the DK424 Base Cabinet (DKSUB424), DK424 Expansion
Cabinets (DKSUE424), and four system processors (RCTUA4, RCTUBA3/BB4, RCTUC3/D4,
and RCTUE3/F4). The processor used in the system depends on the features and number of
telephones and CO lines required. Each cabinet is shipped with its required Power Supply
(RPSU280); the same power supply used in DK280 cabinets.
See Chapter 5 – DK424 Installation for detailed information on installing RCTU PCBs.

DK424 Configuration
System Configuration

Base Cabinet
The DK424 Base Cabinet provides two designated slots for the RCTU processor and six universal
slots for station, line, and feature PCBs. It provides six connectors for expanding the system to a
maximum of six Expansion Cabinets. It comes with a Motherboard Jumper Unit (MBJU) installed
between the R11 and RCTU slot on the front side of the backplane motherboard. The MBJU is
removed only when RCTUE/F is installed. MBJU is installed for all other DK Release 1~4 RCTU
processor PCBs.

Expansion Cabinets
Cabinet and Universal Slot Capacity: Up to six DK424 Expansion Cabinets can be connected to a
DK424 Base Cabinet. The number of DK424 Expansion Cabinets allowed depends on which
processor is installed in the DK424 Base Cabinet.
The DK424 Expansion Cabinets support either six or eight universal slots, depending on which
processor is installed in the DK424 Base Cabinet.
♦

All Expansion Cabinets are six slot cabinets except DK424 Expansion Cabinets. DK424
Expansion Cabinets provide eight slots, but only when connected to a DK424 Base Cabinet
controlled by an RCTUE3/F3 processor with the MBJU removed.

♦

No DK424 Expansion Cabinets are allowed when connected to the DK424 Base Cabinet with
an RCTUA processor installed.

♦

One DK424 Expansion Cabinet provides six universal slots when connected to the DK424
Base Cabinet with an RCTUBA/BB processor installed.

♦

Up to five DK424 Expansion Cabinets provide six universal slots each, when connected to the
DK424 Base Cabinet with an RCTUC/D processor installed.

♦

Up to six DK424 Expansion Cabinets provide eight universal slots each, when connected to a
DK424 Base Cabinet with an RCTUE/F processor installed.

DK424 and DK280 Compatibility
DK424 cabinets replace DK280 cabinets in the DK product line structure. DK424 Expansion
Cabinets began shipping in June 1995 and DK424 Base Cabinets in February 1997. All old DK280
Release 1~3 processors and DK280 Base/Expansion Cabinets can be mixed with new DK424 Base
and Expansion Cabinets with the following criteria (see Tables 4-2 and 4-3):

DK424 Configuration

Processor in DK424
Base Cabinet

1. Last Expansion Cabinet must be a DK424.
2. Depends on the combination of Expansion Cabinets.
♦

DK424 and DK280 Cabinets can be mixed in any combination, with one exception. If seven
cabinets are required, an RCTUE/F processor must be installed in a DK424 Base Cabinet and
the sixth Expansion Cabinet must be a DK424. In this case DK280 Expansion Cabinets provide
six universal slots and DK424 Expansion Cabinets provide eight universal slots.

♦

DK280 and DK424 Base Cabinets provide six universal slots maximum in any configuration
and any RCTU processor can be installed.

♦

DK280 Expansion Cabinets provide six universal slots maximum in any configuration.

Strata DK I&M

DK424 Configuration
System Configuration

♦

DK424 Expansion Cabinets provide six universal slots maximum in any configuration with a
DK280 Base Cabinet, including a DK280 Base Cabinet with an RCTUE/F processor.

♦

DK424 Expansion Cabinets provide eight universal slots in one configuration only: when
connected to a DK424 Base Cabinet controlled by an RCTUE/F processor (MBJU jumper
must be removed - see installation for details). DK424 cabinets provide six universal slots in
all other configurations.

♦

An RCTUE/F processor can be installed in a DK280 Base Cabinet. When an RCTUE/F
processor is installed in a DK280 Base, only five Expansion Cabinets (DK424 and/or DK280)
can be installed. These Expansion Cabinets provide only six universal slots.

♦

All older DK280 Release 1~3 processors will function in the DK424 Base Cabinet. The
features available depend on the respective release and type of the RCTU. These processors
include RCTUA1, RCTUA3, RCTUB1, RCTUB2, RCTUBA3/BB3, RCTUC1/D2 and
RCTUC3/D3.
♦

When an older processor is installed in the DK424 Base Cabinet, the DK424 and DK280
Expansion Cabinets provide six universal slots and the MBJU jumper must be installed see RCTU installation for details.

♦

RCTUA in a DK424 Base allows no Expansion Cabinets.

♦

RCTUB or RCTUBA/BB in a DK424 Base allows one DK424 or DK280 Expansion
Cabinet with six universal slots.

♦

RCTUC/D in a DK424 Base allows up to five DK424 and DK280 Expansion Cabinets in
any combination. These Expansion Cabinets provide six universal slots.

Designated Speaker OCA, DIU Data, and T1 slots
DK424 systems require that PDKU2 PCBs that support Speaker Off-Hook-Call-Announce (OCA)
and PDIU-DS and RPCI-DI PCBs for data applications must be placed in the slots designated in
Tables 4-4 and 4-5.
Note

PDKU2s that support Handset OCA and RPCI TAPI-only can operate in any slot.

Additionally, to enable T1/DS-1 interface, the RDTU PCB(s) must be placed in certain slots, with
corresponding slots left vacant. (The operation of certain channels necessitates vacant slots.)
RDTU PCBs can be placed in the slots in bold type; the vacant slots are not in bold in the
following tables.
Example: for cabinet 1, if an RDTU is placed in slot 13 and you want to use RDTU channels
17~24, then slot 14 must be left vacant. If you installed a second RDTU, it would go into slot 15;
slot 16 must also be vacant if you want to use RDTU channels 17~24.

System Capacity
The number of CO lines and stations needed determine the size of the system. Tables 4-9 and 4-12
show the station and line capacities for eight-port RCOU/RCOS CO line PCBs.
There is a trade-off between stations and lines. Every group of eight stations installed decreases the
CO line capacity of the system by eight, and vice versa. The exact hardware requirements depend
on the features required.
Tables 4-9~4-12 assume one cabinet slot is used for an Optional Interface PCB.

Telephones

Telephones
The DK424 system supports Toshiba Proprietary Digital (DKT) and older series Electronic
Telephones (EKTs). Standard telephones (500 or 2500 series) and devices that require a standard
telephone line interface (fax, modem, VM, etc.) can also be connected to DK424.
Toshiba provides the following 2000-series Digital Telephones for Strata DK424 systems.
♦

DKT-2020SD–20-button speakerphone with LCD

♦

DKT-2010SD–10-button speakerphone with LCD

♦

DKT-2020S–20-button speakerphone

♦

DKT-2010H–10-button handsfree answerback telephone

Toshiba telephones can be equipped with optional subassemblies (listed on Page 4-33).

Attendant Position Options
The DK424 provides three options for attendant positions which answer system incoming calls.
See Table 4-8 for the number of options per RCTU processor. See Table 4-20 for configuration
considerations.
♦

PC Attendant Console–used for medium-to-heavy traffic systems where an attendant must
answer and transfer incoming calls. The PC Attendant Console requires a customer-provided
PC plus the RATU PCB.
Up to two consoles can be connected on systems with RCTUB or RCTUBA/BB or four with
RCTUC/D (Release 2 and 3) and RCTUE/F PCBs. The RATU PCB uses four station ports in
system software. RCTUC/D Release 1 and all RCTUAs do not support the attendant console.

4-16

♦

Direct Station Select (DSS) Console–used for medium traffic systems where an attendant
must answer and transfer incoming calls. The DSS console must connect to circuit 8 on a
PDKU PCB.

♦

Digital Add-On-Module (DADM)–used for medium traffic, smaller systems, where an
Attendant must answer and transfer incoming calls. The ADM connects to any 2000-series
digital telephone. The DADM shares the associated telephones circuit so it does not require a
designated PCB or circuit port (see “DADM” on Page 4-33.)

4. Starting with the lowest empty slot (S12 or S13), record all station, attendant console, loop
start, ground start PCBs from lower to higher numbered slots (left to right). Record the
appropriate port numbers used by each. Do not leave empty slots except when installing
RDTU PCBs (see Tables 4-4 and 4-5).
5. After all station, attendant console, and ground/loop start line PCBs are recorded, write in all
DID and Tie line PCBs starting from the first numbered empty slot to the highest needed (in
left to right order). Record the line numbers. Do not leave empty slots except when installing
RDTU PCBs.
The maximum number of station ports used by station, PC attendant console, Tie, and DID

In some rare configurations, when using RDTU (T1) Tie or DID lines in systems, the
maximum number of stations allowed may be reduced because the RDTU PCB takes up two
or three cabinet slots. Each RDTU, REMU, or RDDU Tie/DID line uses one station port.
RCIU/RCIS PCBs do not use station ports or CO line software time slot assignments.

Worksheet 5 – System Power Factor Check

Worksheet 5 – System Power Factor Check
The Strata DK power supply was engineered for maximum cost efficiency to provide power for
the most configurations. Because of this design, some power limitations exist when using old
electronic-type telephones and/or telephone option hardware.
For example, only 24 3000-series telephones can be installed in a cabinet. Each telephone and
PCB has a negative Power Factor (PF) and the RPSU424 or RPSU280 power supply have a
positive PF (+65). The sum of the telephones’ PFs and PCBs connected to a signal cabinet must
not exceed –65. In the case of +5VDC, the power factor must not exceed 25.
The sum of the calculated cabinet PFs must not exceed the values provided on Page 4-38. Table
4-23 shows the PF for PCBs and the RPSU280. PF numbers for telephones and devices are shown
on the following page.

This chapter explains how to install the Strata DK424 system. It includes information on site
requirements and provides installation instructions for various cabinet configurations. It also
explains how to install ground wiring, AC power cabling, reserve power (Battery Backup) cabling,
and Printed Circuit Board (PCB) cabling.

Inspection
When the system is received, examine all packages carefully and note any visible damage. If any
damage is found, do not open the packages. Contact the delivery carrier immediately and make the
proper claims.
After unpacking (and before installing), check the system against the packing list and inspect all
equipment for damage. If equipment is missing or damaged, contact your supplier immediately.
Be sure to retain original packaging materials for re-use when storing or transporting system
hardware.

Packaging and Storage
CAUTION!

When packaging and storing the system, remove PCBs from the system cabinet (the power supply
may remain installed in the cabinet for storage and shipment). PCBs should be packaged in their
original antistatic bags for protection against electrostatic discharge. Be sure to package equipment
in its original shipping containers.

system requires one or two AC outlets that must be dedicated to system use, fused, and grounded.
See “Power Supply Installation” on Page 5-8 for complete AC power cabling, ground wiring and
battery installation instructions.)
CAUTION!

To avoid accidental power turn-off, it is recommended that an ON/OFF wall
switch not be used on AC circuits dedicated for the use of DK424.

A reserve power source (two or four customer-supplied 12-volt batteries) may be connected to the
DK424 to serve as a backup in case of power failure.

Clearance and Location
The Base and optional Expansion Cabinets may be either floor or wall mounted. Figure 5-1 shows
the minimum clearance requirements. See “Wall Mounting the Base Cabinet” on Page 5-11 and
“AC Power Distribution for Six Cabinets” on Page 5-36 for details.
Notes
●

●

Floor mounting requires the following additional hardware:
●

RFIF – floor mounting stands and brackets.

●

RCCB – electrical conduit box, if three or more cabinets are installed.

Wall mounting may require a plywood (3/4 inch thick) backboard.

When selecting a location for the cabinets, the location must be:
♦

Dry and clean

♦

Well-ventilated

♦

Well-illuminated

♦

Easily accessible

The location must not be:
♦

Subject to extreme heat or cold

♦

Subject to corrosive fumes, dust, or other airborne contaminants

♦

Subject to excessive vibration

♦

Next to television, radio, office automation, or high frequency equipment

Optional customer-supplied reserve batteries require a well-ventilated location close (within nine
feet) to the DK424 cabinets.

1. Only PESU circuits 1 and 2, and RDSU circuits 1~4 provide Off-premises Station (OPS) capability. PESU must use OL13A or
equivalent line conditioning for OPS connection. RDSU must use OL13A or OL13B if providing –24 volt loop voltage. If
equipped with the –48 volt loop option PCB (R48S), OL13A, OL13B, or OL13C may be used for OPS connection.
2. When ordering DS-1/T1 circuits, six items must be specified:
●
The number of channels per T1 circuit, fractional increments are normally 8, 12, or 16 channels, full service is 24 channels.
Unused channels must be bit-stuffed.
●
Type of CO line assigned to each channel: Loop Start, Ground Start, Tie (Wink or Immediate Start), DID (Wink or
Immediate).
●
Frame Format Type: Super Frame (SF) or Extended Super Frame (ESF). The T1 provider normally specifies the Frame
Format to be used, either is adequate for DK424 CO digital voice lines. ESF provides a higher level of performance
monitoring, but requires trained personnel and the ESF CSU normally costs more than an SF only CSU.
●
Line Code Type: Alternate Mark Inversion (AMI) or Bipolar 8 Zero Substitution (B8ZS). The T1 provider normally
specified the Line Code to be used, either is adequate for DK424 T1 CO digital voice lines.
●
The customer may have to provide the Channel Service Unit (CSU) to interface the DK424 T1 circuit to the Telco T1 circuit.
(CSUs are a Telco requirement.)
●
RDTU Network Channel Interface Codes: 04DU9-BN, 04DU9-DNZZ, 04DU9-1SN, 04DU9-1KN, 04DU9-1ZN.
3. For information on how to order ISDN PRI/BRI circuits, you should refer to the Toshiba ISDN Training CBT. ISDN circuits
may require a customer-provided CSU for PRI and/or Terminal Adapter or Network Terminal units for BRI. In U.S. CSU/TAs
must be UL-listed in the U.S. In Canada, they must be CSA certified.

Cabinet Installation Considerations

Cabinet Installation Considerations
The Base (DKSUB424) and Expansion Cabinets (DKSUE424) can be wall or floor mounted. To
make it easier to add cabinets (after the initial installation) when a customer needs to expand,
install the Base Cabinet on top for wall-mount installations and on the bottom for floor-mount
installations.
The dimensions of the Base and Expansion Cabinets are:
Height:

Base Cabinet: 11 3/4 inches

Height:

Expansion Cabinet: 10 inches

Width:

23 5/8 inches

Depth:

9 3/4 inches

Weight:
Note

approx. 30.5 lbs. (14 kg.)

The weight approximates a cabinet completely filled with PCBs. Weight may vary
slightly, depending on PCBs.

Recommended Installation Sequence
Step

1.

Install power supplies in cabinets.

2.

Mount cabinets on floor or wall.

DK424 Installation
Power Supply Installation

Power Supply Installation
The Base and Expansion Cabinets are shipped from the factory without the power supply installed.
The DK424 cabinets use the same power supply (RPSU280 and/or RPSU424) as the DK280.
Note

RPSU280 and RPSU424 are fit, form, and functionally the same. They can be
interchanged and mixed in DK280 and DK424 systems.

➤ To install power supplies in cabinets of new or installed systems
1. Remove the power supply from its box. The box should also contain a plastic bag with two
jumper plugs for the power supply DKSUB or DKSUE connector. An AC power cord and the
power supply mounting screws are provided with the KSU cabinet.
2. Make sure that the front and right side covers are removed from the cabinet (see Figure 5-2).
3. Slide the power supply into the right side of the cabinet so that its four mounting holes align
with the four cabinet mounting holes (see Figure 5-3). (Make sure that the two backplane FG
wires are positioned between the FG wire holder and the power supply.)
Note

The backplane FG wires are not safety grounds: they are required for proper system CO
line operation.

4. Plug the DC OUT cable plug into the DC OUT connector on the power supply. (The plug has
a guide key on it to ensure that it is plugged in correctly.)
5. Secure the FG wire spade lug to the power supply with the FG screw.
6. Secure the power supply to the cabinet with the four provided screws.
7. If the cabinet is the Base Unit, plug the jumper plug that has a wire connected into the
“DKSUB” jumper connector on the power supply.
8. If the cabinet is an Expansion Unit (DKSUE), plug the jumper plug that does not have a wire
connected into the “DKSUE” jumper connector.
Important!

The power supply with the “DKSUB” jumper plug (plug with wire) installed is the
master and has ON/OFF control over all other power supplies, which are
designated as slaves. If the master power supply is turned OFF or ON, all other
power supplies will automatically turn OFF or ON. (Individual power supplies must
be turned on.)
Power supplies that have the “DKSUE” jumper plugs (plug without wire) installed
will not control other power supplies, but can be turned OFF or ON individually
with their own ON/OFF switch. (The master power supply must be on and the
intercabinet “Data” ribbon cable must be installed to allow a slave power supply to
be turned ON.)

9. See Figure 5-3 to ensure that the power supply is properly installed.
10. Install power supplies in all cabinets, using Steps 1~9.
11. Install the Base and optional Expansion Cabinets, ground wiring, AC and reserve power
cabling, and PCB cabling per the “Recommended Installation Sequence” on Page 5-7.
Note

5-8

Power Supply testing procedures are provided in the Fault Finding chapter, which should
be referred to if it is suspected that the power supply does not work properly.

Power Supply Replacement
➤ Install the replacement power supply per “Power Supply Installation” on Page 5-8.

Wall Mounting the Base Cabinet
If the cabinet mounting holes align with wall studs, the cabinet can be installed directly on the wall
(see Figure 5-4). For more than two cabinets, a wooden backboard between the cabinet and the
wall is highly recommended (see Figure 5-5).

Base Cabinet (DKSUB424) Installation
1. If using a backboard: Obtain a board, such as plywood, that is at least 3/4 of an inch thick. The
board should be at least 6-1/2 feet high (completely expanded systems with seven cabinets
require this much height) and two feet wide (minimum).
Secure the board to the wall with wood screws with the bottom edge of the board is six inches
above the floor. (If there are wall studs, make sure the screws align with the studs.)
2. Remove the front, back, and side covers from the Base Cabinet (see Figure 5-6).
Note

The bottom left screw must be completely removed. The two screws on each side cover
and the three screws on the front cover should only be loosened and the covers slid to the
right for removal.

4. Use a level to make sure that the back cover is held level.
5. Trace the upper arch of the top mounting holes with a pencil.

DK424 Installation

3. Hold the Base Cabinet back cover against the wall or backboard so that its two top mounting
holes are approximately 6-1/2 feet (78 inches) above the floor. This allows seven cabinets to
be installed (top-down) with a six-inch clearance between the floor and bottom cabinet (see
Figures 5-7 and 5-8).

6. Remove the back cover from the wall.
7. Draw a line between the top two marking hole marks.
8. Drill holes on the line in the middle of the arch tracing.
9. Screw #12 X 1.25 inch size wood screws into the two drilled holes, leaving about 1/8 of an
inch clearance between the screw heads and the wall.
10. Hang the Base Cabinet back cover from the top two screws and secure the screws into the
wall.

Strata DK I&M

5/99

5-11

DK424 Installation
Wall Mounting the Base Cabinet

11. Drill holes at the bottom two mounting holes of the back cover, and secure #12 X 1.25 inch
wood screws into the two holes.
12. If installing just a Base Cabinet: Position the Base Cabinet on the back cover cabinet hangers,
slide the cabinet to the right to the proper mounting position, and secure the cabinet to the back
cover with two screws on the right side of the cabinet. If installing Expansion Cabinets, skip to
“Cabinet Floor Mounting” on Page 5-21.
13. Install ground wiring, AC and reserve power cabling, and PCB cabling per the
“Recommended Installation Sequence” on Page 5-7.
14. Fill out the slot identification label on the cabinet (see Figure 5-11).
15. Reinstall the front cover, top cover, and side covers onto the cabinet.

Expansion Cabinet Installation (DKSUE424)
Note

Toshiba recommends installing cabinets (see Figure 5-5~5-10 and 5-27) from the top
down, with the Base Cabinet on top, the first Expansion Cabinet below it, the second
Cabinet below that, etc.

1. Remove the front, back, and side covers from the Expansion Cabinets.
Note

The bottom left screw must be completely removed. The two screws on each side cover
and the three screws on the front cover should only be loosened and the covers slid to the
right for removal.

2. Hold an Expansion Cabinet back cover against the wall so that its top locating parts align with
the bottom locating parts of the Base Cabinet back cover. To secure the Expansion Cabinet
back cover to the wall or wall board, repeat Steps 5~11 from “Base Cabinet (DKSUB424)
Installation” on Page 5-11.
3. To install additional Expansion Cabinet back covers, repeat Step 2 above.
4. Starting with the top Expansion Cabinet back cover (which is fastened to the wall), position an
Expansion Cabinet on the back cover cabinet hangers. Slide the cabinet to the right to the
proper mounting position, and secure the cabinet to the back cover with two screws to the right
side of the back cover. Repeat for all other Expansion Cabinets.
5. Loosen the bonding connection plates fastened on both sides of the first Expansion Cabinet,
then fasten the plates between the Base Cabinet and the first Expansion Cabinet. Repeat to
connect the first Expansion Cabinet to the second Expansion Cabinet, etc.
6. Loosen data cable door locking screws and open data cable doors; then connect the first
Expansion Cabinet data cable to the “CAB 2” (top) data cable connector on the Base Cabinet.
Install data cables in appropriate connectors for all other Expansion Cabinets).
7. After all data cables are installed, close data cable doors and secure with the locking screw.
Important!

Data cable door screws must be firmly tightened for proper system operation.

8. Install ground wiring, AC and reserve power cabling, and PCB cabling per the
“Recommended Installation Sequence” on Page 5-7.

AC Power and Grounding Requirements
The system requires a solid earth ground for proper operation and safety. The AC power cord(s)
already contains a conductor for the “third wire ground” provided by the commercial power outlet.
An insulated conductor must connect the frame ground terminal on the Base Cabinet (or the
bottom Expansion Cabinet) to a cold water pipe or the building ground.
Notes
●

The “third wire ground” (“A” in Figure 5-28) must be dedicated. The conductor connected to
the frame ground must comply with the general rules for grounding contained in Article 250 of
the National Electrical Code, NFPA 70, but must not depend on the cord and plug of the
system.
WARNING! Failure to provide ground may be a safety hazard or lead to confusing trouble
symptoms and, in extreme cases, system failure.

AC Power and Grounding Requirements

AC Power and Third Wire Ground Test
Test each “third wire ground” separately for continuity by either measuring the resistance between
the third prong terminal (earth ground) and a metal cold water pipe (maximum: 1 ohm) or by using
a commercially available earth ground indicator. If neither procedure is possible, perform the
following procedure.
➤ To test each “third wire ground” for continuity
WARNING! Hazardous voltages that may cause death or injury are exposed during the
following test. Use great care when working with AC power line voltage.

1. Obtain suitable voltmeter, and set it for a possible reading of up to 250VAC.
2. Connect the meter probes between the two main AC voltage terminals (white and black wires)
on the wall outlet. The reading obtained should be between 100 ~ 125VAC.
3. Move one of the meter probes to the third terminal (green wire ground, point A in Figure 319). Either the same reading or a reading of zero volts should be obtained.
4. If the reading is zero volts, leave one probe on the ground terminal and move the other probe
to the second voltage terminal.
CAUTION!

If a reading of zero volts is obtained on both voltage terminals (white wire to
green wire, black wire to green wire), the outlet is not properly grounded. Omit
Steps 5 and 6, and proceed directly to Step 7.

5. If a reading of zero volts on one terminal and a reading of 100 ~ 125VAC on the other terminal
is obtained, remove both probes from the outlet.
6. Set the meter to the “OHMS/Rx1” scale. Place one probe on the ground terminal, and the other
probe on the terminal that produced a reading of zero volts. The reading should be less than
one ohm.
CAUTION!

➤ To test the frame ground conductor for continuity
WARNING! Hazardous voltages that may cause death or injury are exposed during
the following test. Use great care when working with AC power line
voltage.

DK424 Installation

If the reading is more than one ohm, then the outlet is not adequately grounded.
If the above tests show the outlet AC voltage is not in range or is not properly
grounded, the condition should be corrected (per Article 250 of the National
Electrical Code) by a qualified electrician before the system is connected.

1. Disconnect the AC plug(s) of the system to make sure that the separate earth ground paths are
separated.
2. With a suitable volt/ohm meter, perform a reading between points “A” and “B” shown in
Figures 5-28, 5-21 and 5-22. Verify that the readings do not exceed the figures listed below. If
they do, the condition must be corrected by a qualified electrician before the system is
connected.

Intercabinet Ground
Connect intercabinet ground wires (supplied with each cabinet) between cabinets in systems with
two or more cabinets (Figures 5-21 and 5-22).

AC Power Cabling Installation
The system requires an input power source of 50/60 cycles, 115VAC ± 10 VAC, and up to 17.5
amps AC to operate. AC power cabling requirements vary, depending on the method of cabinet
installation and the number of cabinets. Refer “Summary of Electrical/Environmental
Characteristics” on Page 5-4 for electrical power requirements.
Some floor-mounted configurations and all wall-mounted configurations require AC outlets,
which must be dedicated to system use, fused, and grounded. To avoid accidental turn off, do not
configure the outlet with an ON/OFF switch.

AC Power for One or Two Cabinets (Wall Mount)
Refer to the following instructions to install AC power cabling to floor or wall-mounted systems
with just one or two cabinets:
1. Make sure all power supply (RPSU280) switches are in the OFF position.
2. If two cabinets are installed and local electrical code allows only one AC power cord from the
system, install the RPSB2 in the bottom cabinet per Figures 5-19 and 5-20.
3. For AC power cords that will be plugged directly into a wall outlet: Undo the tie wrap that
keeps the cord coiled. Plug female end of the cord into the power supply, and plug the male
end into the wall outlet.
4. For AC power cords that will be plugged into power strips: Do not undo the tie wrap that
keeps the cord coiled. Plug female end of the cord into the power supply, and plug the male
end into the RPSB power strip. Plug the power strip power cord into a wall outlet (see Figure
5-9).

switches over to battery power without any interruption to existing calls or other normal system
functions.
The length of time reserve power operates depends on the system, size and number of batteries
provided, and the system load. Typical reserve power duration estimates and battery specifications
are estimated with the following considerations (see Table 5-4):
♦

Batteries have full charge at start of operation.

♦

Two or four batteries connected per Figure 5-25.

♦

Batteries are 12VDC, rated at 80 amp/hours each.

♦

System is operating at full load traffic with LCD phones.

♦

Batteries used for this test are gel-cell and maintenance-free. Reserve duration will vary
depending upon battery type, age, and manufacturer. These figures should only be used as an
estimate.

Reserve Power Installation

Reserve Power for One or Two Cabinets (Wall Mount)
1. Connect the black jumper wire (supplied with the PBTC-3M cable) from the positive terminal
of one 12VDC battery to the negative terminal of the second 12VDC battery (Figure 5-20).
2. Ensure that a serviceable 10-amp fuse is installed in the in-line fuse holder of the PBTC-3M
cable.
3. Connect the PBTC-3M battery cable white lead to the open positive terminal of the 12VDC
battery. Connect the black lead to the open negative terminal of the second 12VDC battery.
Important!

The cabinet(s) must be connected to the (live) AC power source, and the power
supply ON/OFF switch set to ON prior to the final step of connecting the reserve
power batteries to the power supply via the BATT+/- receptacle. If the batteries are
connected after AC power is lost, reserve power will not function.

4. Connect the PBTC-3M battery cable two-prong male plug to the Base Cabinet power supply
BATT +/- receptacle.
5. Repeat Steps 3 and 4 to connect a PBTC-3M to the Expansion Cabinet.
6. To test reserve power operation, disconnect system AC power plugs with power supply ON/
OFF switches in the ON position. The system should continue to operate without interruption.
Note

If connecting four batteries, follow the wiring diagram in Figure 5-25.

Reserve Power for Three or More Cabinets (Wall Mount)
1.

Install the Battery Distribution Box (RBDB1A or RBDB2) to the bottom cabinet.

2. Connect two Cable “C” jumper wires from the positive terminal of one 12VDC battery to the
negative terminal of the second 12VDC battery (Cable “C” is supplied with the RBTC1A-2M
cable).
3. Ensure that a serviceable 12-amp fuse is installed in the in-line fuse holder of the RBTC1A2M battery cable.

Reserve Power Installation

Reserve Power/AC Wiring for Three or More Cabinets (Floor Mount)
Floor-mounted systems with three or more cabinets require a Conduit Connection Box (RCCB) to
connect reserve power cabling and AC power cabling to the system. Only a qualified electrician
can install cabling between the reserve power source and AC power cabling to the conduit
connection box. All other steps required to install reserve power, including installation of the
Battery Distribution Box (RBDB), can be accomplished by the normal system installer.
➤ To connect reserve power to floor-mounted systems with three or more cabinets
See Figures 5-23 and 5-26~5-28 and follow these steps:
1. Make sure that the Conduit Connection Box is installed on the bottom cabinet. The box can be
installed by the regular system installer.
2. Have a licensed electrician install conduit and battery cabling to the Conduit Connection Box
and local electrical codes. The remaining steps in this procedure can be performed by the
regular system installer.
3. Install the Battery Distribution Box on the second cabinet (the cabinet directly above the
bottom cabinet).
4. Plug the two Conduit Connection Box cables (coming from the left side of the RCCB box)
into the Battery Distribution Box.
Important!

The cabinets must be connected to the (live) AC power source, and the power supply
ON/OFF switches set to ON prior to the final step of connecting the reserve power
batteries to the power supplies via the BATT +/- receptacle. If the batteries are
connected after AC power is lost, reserve power will not function.

5. Connect RBTC1A-1.5 and RBTC2A-1.7 cables from the (RBDB or RBDB2) Battery
Distribution Box to the BATT +/- receptacle of individual power supplies (6 RBTC1A-1.5
cables come with each RBDB distribution box). RBTC2A-1.7 is a longer cable, required for
the seventh cabinet. It must be special ordered with part number RCTC1A-1.7M.
6. To test reserve power operation, turn off the system AC power circuit breaker with power
supply ON/OFF switches in the ON position. The system should continue to operate without
interruption.

Printed Circuit Board (PCB) Installation

Printed Circuit Board (PCB) Installation
This section provides procedures for the installation of DK424 Base and Expansion Printed Circuit
Boards (PCBs). It includes installation instructions, optional configuration information, wiring,
and programming considerations for each PCB.
The DK424 system Base and Expansion Cabinets are shipped empty. The power supplies and
PCBs are not installed at the factory. PCBs must be installed according to the configuration
information obtained and developed in Chapter 4 – Configuration.
●

Install PCBs only after installing the Base Cabinet and, if applicable, Expansion Cabinets
per the Cabinet Installation section in this chapter.

●

Be sure the power supply has been tested and the ground has been checked.

●

Install universal slot PCBs per the DK424 configuration guidelines.

Note

Information in this section applies to both the Release 3 and Release 4 RCTU PCBs,
unless specified otherwise.

PCB Installation Considerations
The Base Cabinet has eight slots. The first two slots, labeled “R11” and “RCTU” are reserved for
the common control unit and future feature upgrades. The remaining six slots (labeled “S11,”
“S12,” “S13,” “S14,” “S15,” and “S16”) are universal and capable of hosting any of the station,
line, and option interface PCBs compatible with the DK424 systems. (If needed, RSIU must be
installed in slot 11.)
The Expansion Cabinets have eight universal slots, labeled “S_1,” “S_2,” S_3,” “S_4,” “S_5,”
“S_6,” “S_7,”“S_8,” where the blank space of the label represents the number of the Expansion
Cabinet. Like the universal slots in the Base Cabinet, these universal slots are capable of hosting
any of the station, line, and option interface PCBs (except RSIU which can only be installed in slot
11).
The DK424 Expansion Cabinet slots labeled “S_7” and “S_8,” can only be used when an RCTUE/
F processor is installed in the DK424 Base Cabinet. When the RCTUE/F processor is installed in
the DK424 Base Cabinet, the MBJU PCB must be removed from the Base Cabinet to allow S_7
and S_8 to function in the DK424 Expansion Cabinets (see Figure 5-28 to locate MBJU).

Cabinets are numbered from 1 to 7. The Base Cabinet is numbered 1; the first Expansion Cabinet,
number 2; the second Expansion Cabinet, number 3; etc. See the DK424 Configuration and
Universal Slot PCB section for details regarding PCB installation.

DK424 Installation

If RCTUA, BA/BB, or C/D are installed in the DK424 Base Cabinet, only slot S_1~S_6 can be
used in DK424 or DK280 Expansion Cabinets. When these processors are installed in the DK424
Base Cabinet, the MBJU PCB must be installed on the Base Cabinet (see Figure 5-28 to locate
MBJU).

PCB Option Considerations
DK424 PCBs may be configured for a variety of hardware and software options. Hardware options
are defined as either internal (generally related to optional PCB subassemblies) or external (related
to connection of peripheral equipment such as background music, voice mail, etc.). Hardware and
software options for each PCB are identified in the individual PCB installation procedures in this
chapter.

Hardware Options
Some PCBs must be configured for hardware options prior to installation of the PCB in the
cabinet. Configuration instructions for internal hardware options are provided in the individual
PCB installation procedures in this chapter. Configuration instructions for external hardware
options are provided in Chapter 10 – Peripheral Installation.
Software Options
PCBs are configured for software options through programming, following the installation
instructions of the PCBs. A programming overview for each PCB is provided in the individual
PCB installation procedures in this chapter. Refer to the Strata DK Programming Manual for

Integration (LSI) circuitry.
The processor operating software is programmed on four read-only-memory (ROM) chips on the
RCTUA3 or RCTUA4, BB3 or BB4, and D3 or D4 PCBs and on the Flash Memory PCB RMMS
on the RCTUF3 or F4 PCBs. The operating software (ROM or RMMS) is factory-installed.
The RCTU PCBs also provide busy tone detection as a standard feature for Auto Busy Redial
(ABR) and interfaces with optional RRCS DTMF receivers, feature keys (RKYS1, 2, or 3) for
Auto Attendant (AA), Automatic Call Distribution (ACD), Management Information System
(MIS) for ACD, Toshiba proprietary RS-232 and SMDI voice mail interfaces.
ACD and attendant consoles requires the RCTUBA/BB, RCTUC/D and RCTUE/F processors.
Important!

When installing RCTUE/F, you must remove the Motherboard Jumper Unit (MBJU)
from the DK424 Base Cabinet (between R11 and RCTU slot on the front side of the
cabinet motherboard), see Figure 5-28 to locate MBJU. If installing an RCTUA, BA/
BB, C/D, the MBJU must be installed on the DK424 Base Unit.

PCB Installation Power Supply Considerations
1. The power supply must be OFF whenever removing or installing the common control unit—
RCTUA, RCTUBA/BB, RCTUC/D and RCTUE/F (see Figure 5-29).
2. It is recommended that the power supply be OFF, whenever possible, when removing or
installing the other PCBs.

RCTUA, RCTUBA/BB, RCTUC/D, RCTUE/F Common Control Units

Additionally, each of the common control units can support a separate set of features. Refer to
Chapter 4 – Configuration for more information.
Each of the common control units (except RCTUBB) may be equipped with an RRCS (4, 8, or 12)
to interpret Dual-Tone Multi-Frequency (DTMF) signals transmitted from Tie/DID lines, built-in
AA and standard telephone ports. The common control units also provide an interface (along with
a volume control) for a Music-on-hold (MOH)/Background Music (BGM) source.
RCTU PCBs are described later in this chapter.

Internal Hardware Options
The RCTU common control units support the following hardware options:
DTMF Receiver Unit (RRCS-4, RRCS-8, RRCS-12)
There are three RRCSs: the RRCS-4 has four DTMF receiver circuits; the RRCS-8 has eight
receiver circuits; and the RRCS-12 has 12 receiver circuits.The RRCS is shown in Figure 5-31.
The RCTUA can support up to 12 DTMF receiver circuits; RCTUBA has up to 12 circuits; the
RCTUC/D has up to 24 circuits (one RRCS on RCTUC and one RRCS on RCTUD), and the
RCTUE/F has up to 24 circuits (one RRCS on RCTUE and one RRCS on the RCTUF).
RKYS Feature Key Upgrades
The system can be upgraded for built-in AA, ACD, and MIS for ACD with the following feature
keys that attach to the common control unit.

Music-on-hold/Background Music Volume Control (External Options)
Each of the common control units (except RCTUBB, RCTUD and RCTUF) has a trim
potentiometer (VR1) to adjust the volume of the MOH/BGM source connected to the Music-onhold (MOH)/Background Music (BGM) RCA jack interface, which is also on the common control
unit. The volume control potentiometer and the MOH/BGM interface are on the RCTUA,
RCTUBA3, RCTUA4, RCTUC, RCTUE3 and RCTUE4 PCBs.
The VR1 potentiometer does not control the volume of alternate BGM sources connected to either
the RSTU2, RDSU, PSTU, PEKU, PESU, or other BGM source interfaces.
➤ To install the MOH/BGM source to common control unit

RRCS
The DTMF receiver subassembly (RRCS) translates DTMF signals to data signals and attaches to
common control units with 4, 8, or 12 receiver circuits.
RRCS (4, 8, or 12) Installation onto RCTUA

DK424 Installation

➤ Adjust the VR1 potentiometer to the desired volume level while listening to MOH or BGM
(see Chapter 6 – Peripheral Installation).

➤ Mate RRCS connectors J1, J2, J3, and J4 (Figure 5-31) with RCTUA connectors P2, P3, P4,
P5. Apply firm, even pressure to the RRCS to ensure proper mating of the connectors.
RRCS Installation onto RCTUBA, RCTUC/D, and RCTUE/F
RCTUBA provides up to 12 DTMF receiver circuits because an RRCS PCB can be installed on
RCTUBA only and not on RCTUBB.

RCTU Installation

CAUTION!

1. Do not remove the plastic insulation shield from the back of the RCTU PCB. If the
shield comes off, do not allow the back of the PCB to contact metal.
2. The RCTU PCBs are shipped from the factory with the battery jumper in the “OFF”
position. Ensure it is moved to the “ON” position before installing the RCTU to
protect customer configuration information stored in the RCTU RAM.
3. The power supply must be off when installing the RCTU PCB or damage to the
board could result.
1. Set the P5, P8 or P9 battery jumper on the RCTUA, BA3, C3, D3, or RCTUF3 to the “ON”
position (see Figures 5-31~5-38).
2. Ensure the RCTU has been configured for the appropriate hardware options (i.e., RRCS or
RKYS). See “Internal Hardware Options” on Page 5-48.
3. Insert the RCTUA, RCTUBB, RCTUD, or RCTUF (1, 2 or 3) into the “RCTU” slot in the
Base Cabinet. If RCTUA and RSIU is installed, you must also install a ribbon cable between
them (“RSIU, RSIS, RMDS RS-232/Modem Interface Unit” on Page 7-45).
Ensure the component side of the RCTU PCB is facing right when installing it in the Base
Cabinet.
4. Insert the RCTUBA, RCTUC, or RCTUE PCB into slot R11.
5. After installing the RCTU PCBs, gently pull it outward. If the connectors are properly mated,
a slight resistance will be felt.
6. Connect the supplied ribbon cables between RCTUA, RCTUBA and BB and RSIU, if
installed; or RCTUC/D, RCTUE/F, and RSIU, if installed.
Note

Do not adjust the C14 or C15 trimmer capacitor. The capacitor is factory-calibrated.

CAUTION!

When packaging the RCTU PCB, use only a nonconducting material enclosure, such as plain
cardboard. Conductive material can cause the internal battery to discharge and erase memory in
the RCTU PCB.

DK424 Installation

When transporting the RCTU PCBs, keep the P8 or P9 battery jumper in the
“ON” position in order to save the configuration data stored in RCTU RAM.
(The battery will protect RAM for approximately six years.) Otherwise, to
conserve the lithium battery, move the jumper to the “OFF” position.

RCTU Programming
After initially installing a new and unused common control unit, all on-board RAM memory needs
to be erased and initialized by running Program 91-9 twice after all other PCBs are installed. If
RAM contains configuration or feature data from previous programming that should be retained,
do not run Program 91-9. See the Strata DK Programming Manual.

Strata DK I&M

5-51

DK424 Installation
RCTUA, RCTUBA/BB, RCTUC/D, RCTUE/F Common Control Units

If installing a RCTU PCB perform a processor RAM test using Program 00, part 2. On new RCTU
installations, the RAM test should be run after RCTU initialization and before entering the
customer database.
The following parameters can be specified, through programming, for the RCTU PCB.
Program 00, part 2: RCTU RAM test.
Program 03:
➤ For RCTUA, RCTUBA3, RCTUC/D, RCTUE/F—assign the appropriate slot code for each
PCB: slot code 00 for RCTUA, RCTUBA, RCTUC or RCTUE; slot code 01 for RCTUD and
RCTUF.
➤ Assign the appropriate code for each PCB:
♦

Code 91 – no RRCS

♦

Code 92 – four RRCS circuits

♦

Code 93 – eight RRCS circuits

♦

Code 94 – 12 RRCS circuits

Notes
●

●

System Power must be cycled or Program 91-2 must be run after Program 03.
If there are no options on the RCTU, Program 03 can be skipped and Program 91-1 or 919 can be run instead.

➤ Program *03: For RCTUE/F only. Run program to identify DK424 and DK280 cabinets.
➤ Program 12: Select the seize time of the RRCS circuits.
➤ Program 90, 91, 92: RCTU initialization programs.

DK280 to DK424 Base Cabinet Upgrade Considerations
1. Remove MBJU from the DK424 Base Cabinet motherboard.
2. After installing and initializing the RCTUE/F, run Program *03 to identify the DK280 and
DK424 cabinets.
♦

DK280 Expansion Cabinet slots S_1 to S_6 operate; S_7 and S_8 do not.

♦

DK424 Expansion Cabinets slots S_1 to S_8 operate.

Important!

5-52

If installing station and/or CO line PCBs in slots S_7 and S_8, the ports and/or lines
will shift by 4, 8, 16, or 24, depending on the PCBs installed in S_7 and/or S_8.
Toshiba recommends moving the existing 25-pair and modular cables backward, in
order, to the newly installed PCBs to keep the port and CO line numbers matched
with the cable pairs.

Secondary protectors – low voltage

To protect against transient voltages and currents, solid state secondary
protectors must be installed if there is outside wiring, and on all DID and E&M
Tie lines. These protectors, which contain fast semiconductors in addition to fuses,
shall comply with the requirements for secondary protectors for communication
circuits, UL 497A. Care must be taken to ensure that they are very well grounded
to a reliable earth ground. Recommended protectors are available in the fast
Series 6 line from ONEAC Corp., Libertyville, Illinois 60048, (800) 327-8801.
Install and test the secondary protectors precisely to the installation instructions
of thee manufacturer.

This chapter covers information on using T1/DS-1 interfacing. It is available for the DK424. T1/
DS-1 interfacing is not available for the DK14 and DK40i.

Channelization
The Strata DK424 RDTU PCB provides T1/DS-1 interface for up to 24 channels. Each channel
can be individually set for loop start, ground start, Tie, or DID line operation (voice only, not data
lines). Each RDTU can be set in system programming to activate (1~8), (1~16), or (1~24)
channels (lines). Fractional increments of 4, 12, and 20 are also possible but the RDTU will still
assign 8, 16, or 24 channels respectively in system software.
Example: If only 12 channels of fractional T1 are used, assign RDTU as a 16 channel RDTU. The
system will assign 16 CO lines to the RDTU even though only 12 CO lines will be used. To busy
out unused RDTU channels (see “System Programming for T1” on Page 6-3, Step 4). Use Program
03 to set the quantity of RDTU channels.

Slot Assignments
Up to eight RDTU PCBs can be installed in a DK424 to provide up to 192 lines. RDTU PCBs can
be installed in the same cabinets that have analog type CO line PCBs installed. RDTU PCBs must
be placed in designated slots in each of the DK424 cabinets. (See Tables 4-4 and 4-5 in Chapter 4
– DK424 Configuration for RDTU slot installation rules)
If an RDTU is installed in a cabinet (in some cases one or two slots to the right of the RDTU may
not be used in that cabinet) the number of unusable slots in a cabinet (none, 1 or 2) depends on
which slot the RDTU occupies and how many lines (8, 16, or 24) the RDTU is programmed to
provide. Use Program 03 to set the RDTU slot assignments and Channel quantities (Code 71 = 8
ch., Code 72 = 16 ch., and Code 73 = 24 ch.).

RDTU T1 Interface Unit

RDTU Installation
Installing an RDTU (T1) into a Strata DK424 requires a number of system programs to be run.
Toshiba recommends running these programs in the order listed before actually installing the
RDTU into the system. This allows the RDTU to function immediately, including self-check loop
back testing and normal operation, when it is inserted into the system.
➤ To install an RDTU PCB
1. Set jumper wire plugs P1 (LB), P2, P3, and P4 to the OFF position. See “Loop Back Testing”
on Page 6-16 for loop back testing procedures.
See “SW1 Equalizer Switch and Loop Back Jumpers (Internal Option)” on Page 6-2 for the
appropriate SW1 equalizer switch setting.
2. Insert the RDTU (component side facing right) into the appropriate slot and apply firm, even
pressure to ensure proper mating of connectors. (See “Slot Assignments” on Page 6-1 and
Chapter 4 – DK424 Configuration, Worksheet 2 for RDTU slot assignment
recommendations.)
3. After installing the RDTU, gently pull the PCB outward. If the connectors are properly mated,
a slight resistance is felt.

System Programming for T1
1. Run Program 03: Assign the number of RDTU channels used and the cabinet slot number into
which the RDTU will be installed (see “Channelization” and “Slot Assignments” on Page
6-1). If 1~8 channel are required, assign code 71, if 1~16 channels are required, assign code
72, or if 1~24 channels are required, assign code 73 to the RDTU slot. Also, assign RRCS
code to RCTU if RDTU Tie/DID channels are DTMF.
Important!

Special consideration must be taken when installing Tie or DID T1 channels (see
Worksheets in 6.

2. Run Program *41-2: Assign each channel for loop start, ground start Tie (Immediate or Wink),
or DID (Immediate or Wink). See Program *41-2 record sheet (unused channels can remain as
initialized—loop start).
3. Turn system power supply OFF (five seconds) and ON to activate Program 03 and *41-2
program data.
Note

These are the only programs relating to RDTU operation that require system power to be
cycled OFF and ON.

4. Run Programs 16, 40, 39: If an RDTU is connected to a fractional T1 circuit and all the RDTU
channels (8, 16, or 24) are not used, busy-out the unused CO lines from all line groups
(Program 16), all telephone buttons (Program 39), and restrict all stations from accessing the
unused lines (Program 40).

5. Run Programs 15 and 30: If RDTU Tie and/or DID are dial pulse: Run Program 15-1, LED
ON for each DP Tie/DID line and run Program 30, LED 11 ON for each Tie/DID station port.

Strata DK I&M

5/99

DK424 T1

Example, if the Network fractional T1 provides 12 channels, set the RDTU connected to this
T1 for 16 channels in Program 03 (with code 72). If this RDTU is the first CO line PCB in the
system, the RDTU CO lines will be numbered 001~016. Use Programs 16, 39 and 40 to deny
use of all unused lines (i.e., lines 13, 14, 15, and 16). In this case the first 12 lines are usable;
lines 13, 14, 15, and 16 cannot be used. The CO lines on the next CO line PCB (any type)
following the RDTU PCB will start numbering at line 017.

6-3

DK424 T1
RDTU T1 Interface Unit

6. Run Program 17.
♦

LED 01: For RDTU Tie lines, set LED01 to allow (ON) or deny (OFF) Page and Voice
Announce on incoming calls to DK424 stations from the far end T1 Tie line stations. This
option (LED01) does not apply to RDTU DID lines—Page and Voice Announce is always
denied to incoming DID calls because of FCC “answer supervision” rules.

♦

LED 02 (Wink/Immediate): This assignment is for RDDU, REMU, and PEMU lines only;
it does not apply to RDTU Tie or DID lines. Use Program *41-2 to assign RDTU lines for
wink or immediate start.

♦

LED 03: Toshiba recommends turning this LED ON (initialized state) for all RDTU DID
lines to enable incoming DID calls to camp-on busy stations. This is also necessary to
allow more than one DID line to ring into a station simultaneously. LED03 does not apply
to RDTU Tie lines.

♦

LED 04: For RDTU Tie lines, LED04 is normally OFF to enable dial tone to be received
from the far end Tie line when calling DK424 stations. For DID lines LED04 is normally
ON so RDTU DID lines do not send dial tone to the CO Run *41-1: Use this program to
assign the RDTU (T1) Line Coding method (B8ZS or AMI) and signal Framing format
(SF or ESF). Contact the account representative of the company that is providing the T1
span line (Local Central Office or Long Distance Provider) to determine which line
Coding and Frame format will be used.

♦

Line Coding: The DK424 RDTU supports T1/DS-1 transmission of Voice and Analog
Data (using modems) using Alternate Mark Inversion (AMI) with Zero Code Suppression
(ZCS) or Bipolar Eight Zero Substitution (B8ZS) line coding. B8ZS provides clear
channel capability, which allows frame information bits to carry any combination of ones
and zeros—a feature needed for T1/DS-1 transmission of digital DATA (DK424 does not
support transmission of digital DATA over RDTU T1/DS-1 at this time).

♦

As of this writing, most Telcos provide AMI line coding which is adequate for DK424
RDTU voice transmission; however, B8ZS may be required by some long distance
providers, college campus private networks, or customer premise end to end T1
connections. AMI and B8ZS are adequate for DK424 Voice T1/DS-1 transmission.

♦

Framing: As of this writing, D3/D4 Superframe (SF), or Type I and Extended Superframe
(ESF), or Type II T1/DS-1 is offered by most all local Telcos and Long Distance
Providers. Normally the local Telco will provide SF, which is adequate for DK424 voice
(and modem type data) transmission. Long distance providers may offer either SF or ESF.

ESF provides a more enhanced method of error checking that SF; however, the Channel
Service Unit (CSU) must be compatible with ESF and may cost more than a SF only CSU.
ESF circuits have the additional power of Cyclic Redundancy Checking (CRC), which allows
end-to-end monitoring of T1 circuit performance. ESF, T1 performance monitoring normally
requires that a person be specially trained for this function. SF and ESF Frame format is
adequate for DK424 Voice (and modem type data) T1/DS-1 transmission.
7. Run Programs *41-3 and -4: These programs allow the RDTU Transmit and Receive (Volume)
level to be adjusted by changing the RDTU built-in digital PAD value between +6 decibels
(dB) and –15 dB. Transmit and Receive levels are individually adjustable on each RDTU (all
channels will have the same level). Toshiba recommends using the initialized levels (Receive
–3 dB/Transmit –6 dB) upon initial installation. Adjust the RDTU digital PAD as required
while testing each RDTU T1 channel.
8. Run Program *42 Series—T1 Span Timing Reference Assignments
Timing references for T1 RDTU PCBs are made with the Program *42 series. The RDTU (T1)
timing (or synchronization) program options determine how the DK424 system digital voice

6-4

DK424 T1
RDTU T1 Interface Unit

transmission path (time-switch) is synchronized with the far end digital system transmission
path. For proper T1 operation, the equipment at each end of a T1 span line must be
synchronized.
The DK424 time-switch is synchronized (as slave) to the T1 span equipment on the other end
of the T1 line by the RDTU PCB designated as the Primary Reference in Program *42-1.
When a RDTU is connected to a Telco or Long Distance Provider T1 span line, the RDTU in
the lowest slot number should be assigned as the Primary Reference RDTU (*42-1, DATA = 1
FOR THIS RDTU).
If a malfunction occurs and Primary Synchronization is lost, the DK424 automatically
switches modes and synchronizes to the T1 span connected to the RDTU PCB designated as
the Secondary Reference (provided that there are two RDTU PCBs installed in the DK424)
(see Figure 6-1).

Primary Reference Synchronization:
In this diagram RDTU(1) is the primary reference, its synchronization circuit sends the clock
reference from the TELCO T1 span to the DK424, to the RCTU synchronization circuit, via
RDTU1 Software Switch (SS). The RCTU(1) clock synchronizes the DK424 digital
transmission voice path (via RCTU time switch) to the TELCO/STRATUM1 clock source.
Secondary Reference Switch-Over:
If the primary reference T1 RDTU(1) fails, the DK424 will automatically open the RDTU(1)
primary synchronization circuit (SS1) and close the RDTU(2) secondary synchronization
circuit (SS2). At this time, the DK424 digital voice path will be synchronized to the AT&T/
STRATUM1 clock source.
Slip example:
In the above diagram the “Other T1 Provider” is not synchronized to the STRATUM1 clock
source properly – Slip problems will occur on RDTU(3) T1 channels.

If there are two RDTU PCBs installed, it is recommended not to install the Primary and
Secondary Reference RDTU PCBs in the same DK424 cabinet if possible (although both
Primary and Secondary Reference RDTU PCBs can be installed in the same cabinet). The
Secondary Reference RDTU should also be connected to a Telco or Long Distance Provider
T1 span (*42-2, Data = 2 for this RDTU).
If the equipment on the other end of the DK424 T1 lines should synchronize to the DK424
clock source, then blanks should be entered in Program *42. In this case, the DK424 clock
runs free and is considered the Master Synchronization provider. The DK424 can be assigned
as the Master (free run) clock provider if the far end equipment connected to the RDTU T1
span is a Customer Premise type equipment and it is not synchronized to some other T1
provider (i.e., PBX, Channel Bank, Key/Hybrid or other DK424). In this case (when the Telco
network is not connected), either the DK424 RDTU span or the far end equipment can be the
Master (synchronization clock provider).

Program *42-1, Primary Timing Reference Assignment: Assign the Primary Timing
Reference with this program.

Important!

The Digital Network is connected to clocks with various degrees of precision called
stratum levels from Stratum 1 (highest level of accuracy) to Stratum 4 (lowest level)
as follows:
•

Stratum 1—Public Telephone Network clock located in Hillsboro, Missouri.

•

Stratum 2—Normally associated with #4 ESS Toll switches.

•

Stratum 3—Normally associated with #5 ESS Central offices.

•

Stratum 4—Normally associated with Digital PBXs.

•

If a DK424 RDTU is programmed as the Primary Synchronization Clock
reference, the clock provider connected to this RDTU should be a reliable clock
provider, such as a Telco or common carrier (Example—AT&T). All other T1 span
lines connected to RDTUs in the DK424 must be synchronized to the same clock
source as the AT&T span line. If a T1 span line is not synchronized with the
primary clock provider (AT&T, for this example), then DK424 lines assigned to
this T1 span line (RDTU) may experience “slip” problems.

9. The programs in Steps 1~8 are described for specific RDTU application programming. Also
refer to “System Programming for T1” on Page 6-3. Run the programs as they apply to RDTU
CO line applications.

Local loop back and network loop back test cannot be performed simultaneously.
CSU local/network loop back is a function of the CSU, not all CSUs provide this function –
see CSU I&M documentation for CSU loop back test procedures.

8. After loop back testing is complete and synchronized with the far end T1 circuit, perform test
calls on all RDTU lines. (Use the troubleshooting procedures in “T1 Fault Isolation” on Page
6-20 to help correct problems.)
9. Check T1 performance periodically for transmission errors using the “T1ERR” test. This
requires a local or remote maintenance terminal connected to the PIOU or PIOUS PCB (local)
and IMDU or Hayes-compatible modem (remote).

Applications

Applications
Each RDTU T1 PCB requires the following connecting equipment and cables to provide service
(see the following sections and Figure 6-4).

RDTU to Network
If the RDTU must interface to a public telephone network or common carrier T1 circuit, the
RDTU must be connected to a CSU. Use the NDTU cable (30 ft. cable supplied with RDTU) to
connect the RDTU to the CSU. The function of the CSU is to provide the required interface
between the RDTU PCB and the Public Telephone or Carrier Network. The interface created by
the CSU normally provides protection and capabilities for loop back testing both the Network
equipment and the RDTU PCB.
Connecting the CSU to the Network Interface Unit (NIU) is specified by the CSU manufacturer—
see CSU installation documentation. Toshiba does not supply the cables and connectors required
to connect the CSU to the NIU (see “RDTU Cable Installation”).

RDTU to PBX T1 (Separated More Than 655 ft.)
If the RDTU must interface to a customer’s premises T1 circuit (PBX, key/hybrid, or another
DK424) to provide Tie line service, the RDTU must be connected to a CSU (with Toshiba NDTU
cable) if the other customer premise T1 equipment is more than 655 ft. from the RDTU. The T1
span on the other end must also connect to a CSU.

Applications

RDTU to PBX T1 (Separated Less Than 655 ft.)
If the RDTU is within 655 ft. of the far-end PBX T1 circuit, a CSU is not required. However,
connecting a RDTU T1 span to another PBX or Key/Hybrid T1, in a Tie line configuration at a
distance less than 655 ft. (without a CSU) will require a customer provided special cable. The
transmit and receive pair of this span cable must be separated by at least five cable pairs and the
wires must be 24 AWG, twisted pair, otherwise 22 AWG, ABAM type cable must be used. See
“RDTU Cable Installation” on Page 6-14.
CSUs are not required if the RDTU is less than 655 ft. from the channel bank (see Figure 6-5).
Two CSUs (customer provided) are required if the RDTU is more than 655 ft. from the customer
premise channel bank (see Figure 6-6).
In Figures 6-5 and 6-6, special cable and connectors are customer-provided.

Hardware and Cabling

Hardware and Cabling
RDTU Cable Length Switch
The distance between the DK424, RDTU and CSU or RDTU to other Customer Premise
Equipment (CPE) T1 may vary (0~655 ft.) as shown. (See Figures 6-4, 6-5, and 6-6.) The RDTU
interface transmitter must be equalized and its impedance must be matched to the cable length
connecting the RDTU to the CSU or other CPE, T1.
RDTU transmit equalization/ impedance matching is accomplished by setting RDTU SW1 for the
proper cable length (see Figure 6-5 for SW1 location and “SW1 Equalizer Switch and Loop Back
Jumpers (Internal Option)” on Page 6-2 for SW1 setting instruction).

RDTU Loop Back Jumper Plugs
The RDTU PCB provides jumper plugs for loop back testing. Loop back tests are described in
“Loop Back Testing” on Page 6-16.

RDTU Front Panel Indicators
The RDTU PCB provides seven LED indicators to show the status of RDTU: Busy or Idle
condition, Alarm status, and Synchronization status. See Table 6-2 for the function of each status
LED. Figure 6-2 shows the LED locations.Busy LED (BSY)—Turns on when one or more RDTU
channels (lines) are in use. Also, when the RDTU does not receive the far end 1.544 mbs carrier
signal, the RDTU will cause the BSY to be on steady.
Alarms are used to indicate potentially serious telephone network problems. Example: when
monitoring a T1 network, if a Blue or Yellow alarm is indicated, it can be concluded that there is a
cable fault or some other serious transmission impairment.
Frame Alarm (FALM)—This LED turns ON steady if the RDTU has not achieved
synchronization or when the span cable is not connected.

♦

Multi-Frame Alarm (MFALM)—LEDs turn ON steady if the RDTU receives the 1.554 mbs
T1 carrier from the far end, but has not achieved Frame synchronization or when the span
cable is not connected. Also, if the RDTU is set for SF and the far end is sending ESF (or vice
versa), the MFALM LED will be ON steady.

♦

Red Alarm (FALM and MFALM)—When FALM and MFALM are both ON steady, a Red
alarm condition exists. This indicates that the RDTU does not detect a proper carrier signal
(1.544 mbs T1) on its receive pair and the RDTU is not synchronized. When the Red alarm
condition exists, the RDTU should turn the BSY LED ON steady and attempt to send a Yellow
alarm signal (RDTU YALM LED flashes) to the far end T1 circuit.

♦

Yellow Alarm (YALM)—When the far end network or CPE T1 does not detect the RDTU
transmitted 1.544 mbs T1 carrier signal on its receive pair the far end T1 sends a Yellow alarm
signal pattern to the RDTU—the RDTU should turn on the YALM LED (the YALM repeats
the signal it receives from the far end—flashing or steady). If the RDTU does not receive the
far end carrier signal, the RDTU sends the Yellow alarm signal to the far end and causes the
BSY and YALM LEDs to flash.

♦

Blue Alarm (BALM)—The Blue alarm, also known as the Alarm Indication Signal (AIS), is
detected by the RDTU. This signal is sent by the Far End Network equipment to RDTU when
it loses the carrier from a Network T1 circuit (other than RDTU). This signal assures that the
RDTU maintains synchronization when there is a problem between two Network Nodes. The
RDTU BALM also lights if the far end sends a Blue alarm signal during loop back. The RDTU
sends a Blue alarm signal when loop-back test is being performed.

Synchronization LEDs
♦

Primary Synchronization (PSYNC) LED (see Figure 6-1 on Page 6-6) – If one RDTU PCB is
assigned as the Primary Timing T1 PCB in Program *42, the PSYNC LED of this RDTU PCB
flashes when it is synchronized with the far end T1 span line clock provider. If the Primary
RDTU is not synchronized with the clock provider, the PSYNC LED will be ON steady. The
SSYNC LED of the Primary sync RDTU PCB should always be OFF. The Primary sync
RDTU PCB synchronizes the RTCU (time-switch) to the clock signal it receives from the T1
span circuit to which it is connected. The RTCU then synchronizes the DK424 PCM talk path
(time-switch) to the far end PCM talk path.

♦

Secondary Synchronization (SSYNC) LED – If an RDTU PCB is assigned as the Secondary
time T1 PCB in Program *42, its SSYNC LED will be ON steady (standby mode) when the
DK424 is synchronized to the Primary T1 clock provider. In the event of a loss of Primary
synchronization (when 4 out of 12 consecutive frame timing bits are in error) the DK424
switches from synchronizing to the Primary RDTU span line clock to the span line clock
connected RDTU designated as the Secondary Timing Reference. When the DK424 is
synchronized to the Secondary Reference RDTU, the PSYNC LED on the Primary Reference
RDTU turns on steady and the SSYNC LED on the Secondary Reference RDTU will flash.

♦

Run Free (PSYNC/SSYNC) – If the RDTU PCB is the clock provider to the Far-end T1 span
circuit both the PSYNC and SSYNC LEDs are always OFF.

RDTU Cable Installation
The RDTU PCB is shipped with a Toshiba NDTU cable for connecting the RDTU PCB to a CSU.
The NDTU is a 30 ft. cable and is specially made to conform with EIA specifications (see Figure
6-7).
All other cables required to connect the T1 span line to the RDTU PCB are customer-supplied and
must conform with EIA specification, see the Notes of Figure 6-7. Almost all CSU manufacturers
supply cables that comply with T1 span specifications for connecting the CSU to customer
premise equipment (like DK424, RDTU) to the Network Interface equipment.

Performance Monitoring
The performance of the RDTU can be monitored using the Data Dump Mode. This requires an
RSIU, RSIS, PIOU or PIOUS PCB, an ASCII terminal (or PC) and, if monitoring RDTU
performance from a remote location, an IMDU or RMDS modem or Hayes compatible modem is
required.
The RDTU monitoring feature provides a printout (or CRT display) of RDTU detected T1 errors
as shown in Figure 6-10. There are no time parameters given with this error report so the time
between error count increments must be monitored manually. Basically the error count of any error
category should not increase within 24-hour periods (see Table 6-2 on Page 6-21).

T1 Fault Isolation

➤ To receive the “T1 ERROR DISPLAY” from a terminal (local or remote)
1. Establish communication with the terminal or PC using a communication software (e.g.,
Procomm®).
2. Enter the security code, and press Enter (or Return).
3. At the >MODE prompt, type DUMP (must be all caps), press Enter (or Return). The >D
prompt displays on your screen.
4. At the >D prompt, type T1ERR and press Enter (or Return). The display (see Figure 6-10)
shows all RDTU PCBs (DTUNO=1~DTUNO=8) even if the associated RDTU (1~8) is not
installed. The ERROR counter can only be reset by turning the DK424 OFF and ON.
Use Table 6-2 for recording customer’s problems.
➤ To exit the dump mode
➤ At the >D prompt, type QUIT, press Enter (or Return); the >MODE prompt displays.

T1 Fault Isolation
T1 fault troubleshooting can be complex and may require expensive test equipment to perform the
necessary fault isolation. Because of the high cost, many dealers have not purchased T1 test
equipment. As a result, on a cutover when an RDTU does not synchronize or CO lines simply do
not function, the site technician can only check wiring and cabling. Without proper test equipment,
there is very little that can be tested.
This section provides some procedures that can be done without T1 test equipment to help find the
cause of a failure, or at least determine if system hardware is functioning properly.
The DK424 also provides T1 “in-service” monitoring which allows maintenance personnel to
detect line errors without introducing any disturbances on the line. This method of testing permits
maintenance personnel to monitor T1 performance without the expense of test equipment or
without taking the T1 circuit out of service. The T1 error check is particularly useful for
monitoring the T1 circuit for intermittent problems that may become more serious as time
progresses (see “RDTU Performance Monitor Printout” on Page 6-19).
If experiencing problems with an RDTU span circuit, refer to Flowcharts 6-1~6-3 to isolate the
fault. The flowcharts in this section use the same logic symbols as those used in DK. Document
error information in Table 6-2, “RDTU T1 Error Record” on Page 6-21.

DK40i/DK424
Universal Slot PCBs

This chapter contains information on Printed Circuit Boards (PCBs) which can be used in the
universal slots of either the Strata DK40i Expansion KSU or the Strata DK424 cabinets. Although
the system architecture of these systems is very different, the PCBs described in this chapter are
common to both systems.
Important!

When installing these circuit boards in the DK40i Expansion KSU, you must install
them in the universal slots designated in Chapter 2 – DK40i Configuration.

PCBs which are not installed in the universal slots of the system can be found in the installation
chapter for the system. For example, the TCOU PCB for the DK40i system appears in Chapter 3 –
DK40i Installation. Paragraph headings identify information which is specific to a particular
system and minor exceptions are mentioned in text.
Prior to PCB installation, the power supply must be tested and the ground checked.

The RDDU provides four Direct Inward dialing (DID) lines, each of which can have a single
office code along with a block of extensions. If an RDDU is installed, an RRCS must be
installed for DTMF operation, but not for dial pulse operation.
Each extension can be assigned to ring a station [DN] that appears on one or multiple staitons,
Distributed Hunt or ACD Group (DK424 only), or an external tlephone number selected in
system programming. This enables calls over the same line to be routed to difernent staions or
group of stations. An extension can alos be assinged to ring the maintenance modem. Each
RDDU can be set for either wink start or immediate. All RDDU lines support DNIS and ANI
features.

KCDU
CO Line/Digital Telephone Interface Unit
System:

DK40i Expansion KSU

Circuits per PCB: two CO loop start/four digital telephone circuits
Interfaces with:

central office loop start lines
digital telephones (with or w/o RPCI-DI or ADM)
PDIU-DS
DDCB
cordless digital telephone (DKT2004-CT)

Older Version(s): none

One or two KCDU PCBs may be installed in the Expansion KSU. For controls, connectors, and
indicators, see Figure 7-1 and Table 7-1.

KCDU Configuration
The KCDU may have to be configured to control excessive loudness if the system is close to a CO
or installed behind a PBX telephone system. It does not have to be configured for anything else.
The decibel (dB) PAD switches, SW501 (CO1) and SW601 (CO2), control the loudness by
providing a 3 dB signal level drop to, or from, the PBX or CO when set to the PAD position. The
switch comes from the factory set at NOR (for normal) meaning no PAD loss.

KCDU Installation
1. If the system is located within one mile of the CO or PBX telephone system, set dB PAD
switches SW501 and SW601 to the PAD position.
2. Insert the KCDU into the appropriate slot in the Expansion KSU, per tables in Chapter 2 –
DK40i Configuration. Apply firm, even pressure to ensure proper mating of the connectors.
3. After installing the KCDU, gently pull the PCB outward. If the connectors are properly mated,
a slight resistance will be felt.
Note

If KCDU CO lines receive Caller ID, RCIU2 must be installed.

KCDU Programming
See “RCOU Programming” on Page 7-29 and “PDKU2 Programming” on Page 7-6 for KCDU
programming information. When running Program 03 for the KCDU slot(s), specify code 65 if the
KCDU does not support OCA or PDIU-DI telephones or code 66 if the KCDU supports OCA or
PDIU-DI telephones. Do not specify code 11, 61, 62, or 64.

PEPU2 External Page Interface Unit

System:

RCIU1–DK424
RCIU2 –DK40i Expansion KSU, DK424
RCIS–DK424

Circuits per PCB: four Caller ID circuits
Interfaces with:

loop or ground start lines w/Caller ID (requires RCOU or RGLU2)

DK40i/DK424 Universal
Slot PCBs

RCIU1, RCIU2, RCIS
Caller ID Interface

Older Version(s): none

The RCIU1, RCIU2 PCB provides the Caller ID feature, also known as Calling Number Delivery
(CND). There are two types of RCIU PCBs, RCIU1 and RCIU2. RCIU1 can be used in DK424
systems. RCIU2 can be used in DK424 and DK40i systems.
CAUTION!

To prevent system malfunction, DO NOT install RCIU1 in the DK40i system.

Caller ID can be provided on analog loop start lines (PCOU, KCDU, RCOU PCBs) and analog
ground start lines (RGLU2 PCB) only. It is not available on any other type of analog lines (RDDU/
DID and/or REMU, PEMU Tie) or any type of digital lines (RDTU- T1, including ground start,
loop start, DID and Tie lines).
An RCIU1/RCIS or RCIU2/RCIS circuit must be available in addition to each RCOU, RGLU,
etc., line that is to receive Caller ID. When ordered from the factory, the RCIU1, RCIU2 PCB
comes equipped with four caller ID circuits.

RCIS PCB
An RCIS piggy-back PCB can be installed onto the RCIU to provide an additional four caller ID
circuits. Hence, an installed RCIU/RCIS can provide a maximum of eight caller ID circuits per
cabinet slot.
To provide up to eight circuits, always install RCIS onto RCIU1 (DK424 only) or RCIU2 (DK40i
and DK424) instead of installing two RCIU PCBs (Program 03 code 81 always assigns each RCIU
slot with eight software caller ID circuits).
Each RCIU/RCIS Caller ID circuit has a two-wire tip/ring interface which must be bridge-wired
across its corresponding ground or loop start CO line tip/ring on the MDF (see Figure 8-27 on
Page 8-28). Each RCIU/RCIS modular jack provides interface for two Caller ID circuits.

DK40i RCIU2 Installation
➤ Install RCIU2 in slot 17 only (see Figure 7-12 and Chapter 2 – DK40i Configuration.)

DK424 RCIU1 or RCIU2 Installation
➤ Install the RCIU1/RCIU2 PCBs in any universal cabinet slot of the DK424 (except slot 11 or
slot 12 if the RSIU is installed in slot 11).
Note

Strata DK I&M

It is not necessary to install the RCIU1, RCIU2, RCIU1/RCIS, or RCIU2/RCIS PCBs in
the same cabinet as their associated CO lines or in slots adjacent to the lines.

5/99

7-23

DK40i/DK424 Universal Slot PCBs
PEPU2 External Page Interface Unit

DK424 RCIU1/RCIS or RCIU2/RCIS Installation
1. Install the RCIS onto the RCIU1 or RCIU2 as required (see Figures 7-11 and 7-13).
2. Install the RCIU1/RCIS or RCIU2/RCIS into the appropriate cabinet slot. The circuit modular
jack numbering and the tip/ring cross connect wiring of RCIU1/RCIS or RCIU2/RCIS to
RCOU, PCOU, or RGLU is shown in Figure 8-25 on Page 8-26.
Note

It is not necessary to install the RCIU1, RCIU2, RCIU1/RCIS, or RCIU2/RCIS PCBs in
the same cabinet as their associated CO lines or in slots adjacent to the lines.

RCIU1, RCIU2, RCIS Programming
Program 03: Program each RCIU1, RCIU2, RCIU1/RCIS or RCIU2/RCIS (four or eight Caller ID
circuit) slot with code 81.
Note

RCIU1/RCIS or RCIU2/RCIS caller ID circuits are numbered automatically in numerical
order starting with the RCIU1/RCIS or RCIU2/RCIS installed in the lowest slot number.
Slots with code 81 increment the Caller ID circuit numbers by eight circuits even if RCIS
is not installed on the RCIU1 or RCIU2.

Program *50: Assigns CO lines that will receive Caller ID to an associated RCIU1/RCIS or
RCIU2/RCIS Caller ID circuit number. This assignment is flexible, i.e., any RCOU, PCOU,
RGLU Caller ID CO line can be assigned to any RCIU1, RCIU2 or RCIS caller ID circuit number.
Note

After assigning CO lines to caller ID circuits, turn system power OFF for approximately
five seconds and then back ON or run Program 91-2 to activate Program *50 assignments.

Program *51: Sets the Caller ID (CLID)/Automatic Dialed Number Identification (ANI) memory
allocation for the appropriate stations. This memory is used to save CLID/ANI telephone numbers
for calls that are received but not answered (abandoned calls). CLID/ANI numbers are not saved in
station memory if they are answered. Stations can be allocated with memory to save up to 100
numbers in 10-number increments.
The total memory allocated to all stations in a system is:
♦

RCTUE/F = 2000 numbers

♦

RCTUC/D = 1000 numbers

♦

RCTUBA/BB = 400 numbers

♦

RCTUA and DK40i = 200 numbers

Note

When a CO line rings multiple stations, a station must be the owner of the Caller ID or
ANI CO line to be able to save abandoned call (Caller ID and/or ANI) telephone numbers.
(See Program *52.)

Program *52: Assigns stations as owners of Caller ID CO lines. These stations will store the Caller
ID telephone numbers received on abandoned (not answered) calls for the lines which they own.
Typically all common CO lines are assigned to one designated telephone or attendant console and
private lines are assigned to individual private line telephones.

Older Version(s): PCOU2 (does not have ABR circuitry, uses RCTU, K4RCU ABR circuits)
PCOU1(has ABR circuitry, identical and interchangeable w/PCOU2)

The RCOU also provides ring detection, dial outpulsing, and hold circuitry. Each RCOU line can
be programmed for DTMF or dial pulse signaling and gas tube secondary protection.
RCOU PCBs are shown in Figure 7-14 and described in Table 7-9.

RCOS Installation (Internal Option)
An RCOS PCB can be installed on the RCOU of the DK40i and DK424 for four more loop start
lines (for a total of eight lines–the RCOS circuits provide the same options as the RCOU). Each
RCOS circuit has gas tube secondary protection.
Excessive loudness which is caused by close proximity to a CO or PBX telephone can be fixed
through the RCOS and RCOU decibel (dB) PAD switches. RCOS dB switches SW501, SW601,
SW701, and SW801 and RCOU dB switches SW101, SW201, SW301, and SW401 provide a -3
dB signal level drop between the PBX and CO when set to position 3. Switches are factory-set at
the 0 (0 dB signal level drop) position.
See Figure 7-12 and Table 7-10 for RCOS controls, indicators, and interface connectors.
➤ To install an RCOS PCB
1. If the Strata DK system is within one mile of the PBX or CO, set the RCOS dB PAD switches
SW501, SW601, SW701, and SW801 to the 3 (-3 dB signal level drop) position. Set the
RCOU dB PAD switches to position 3 also.
Note

RCOU male connectors P11, P12, P13, and P14 are positioned to allow installation of the
RCOS only in the proper position.

2. Mate the RCOS female connectors J11, J12, J13, and J14 (Figure 7-16) to the RCOU male
connectors P11, P12, P13, and P14 (Figure 7-14).
3. Apply firm, even pressure to the RCOS to ensure proper mating of connectors.

Circuits per PCB: four DID lines
Interfaces with:

DID (one or two-way) lines

Older Version(s): none

DK40i/DK424 Universal
Slot PCBs

RDDU
Direct Inward Dialing Line Interface Unit

The RDDU provides four Direct Inward Dialing (DID) lines, each of which can have a single
office code along with a block of extensions
Note

For the system to recognize the DTMF tones generated by incoming DID lines a DTMF
Receiver Unit (RRCS -4, -8, or -12) must be installed on the DK40i Base KSU K4RCU3
or on any DK424 RCTU.
RRCS is not required for RDDU dial pulse operation (see Program 30, LED 11).

Each extension can be assigned to ring a station [DN] that appears on one or multiple stations,
Distributed Hunt or ACD Group (DK424 only), or an external telephone number selected in
system programming. This enables calls over the same line to be routed to different stations or
groups of stations. An extension can also be assigned to ring the maintenance modem. Each
RDDU can be set for either wink start or immediate. All RDDU lines support DNIS and ANI
features.
RDDU controls, indicators, and interface connectors are shown in Figure 7-18 and described in
Table 7-12.

RDDU Installation
Note

Switches are factory-set to the 0 (0 dB signal level drop) position.

1. If the KSU is located within one mile of the PBX or CO, set dB PAD switches SW101 through
SW401 to the 3 (-3 dB signal level drop) position to control excessive loudness resulting from
close proximity to the PBX or CO.
2. Sensitivity jumpers P101~P401 are used mostly for dial pulse operation, to adjust for dial
pulsing at different loop lengths. If close to the central office, the sensitivity should be set for
low (L); as the loop length increases, it should be set to medium (M), then high (H).
3. Insert the RDDU (component side facing right) into the appropriate slot and apply firm, even
pressure to ensure proper mating of connectors. (For DK40i, RDDU must be installed per
tables in Chapter 2 – DK40i Configuration.)
Important!

Each RDDU PCB uses four station ports in software. See Worksheets in Chapter 2 –
DK40i Configuration for recommended RDDU slot assignments.

4. After installing the RDDU, gently pull the PCB outward. If the connectors are properly mated,
a slight resistance is felt.

RGLU2 Installation
Note

The decibel (dB) PAD switches SW101, SW201, SW301, and SW401 control excessive
loudness resulting from close proximity to a central office or PBX telephone office by
providing a -3 dB signal level drop to, or from, the PBX or central office when set to the 3
position. Switches are factory set to the 0 (0 dB signal level drop) position.

➤ To install an RGLU2 PCB
1. If the DK KSU is within one mile of the PBX or central office, set the dB PAD switches
SW101, SW201, SW301, and SW401 to the 3 (-3 dB signal level drop) position.
2. Set each line for ground start (GND) or loop start (LOOP) by setting the following jumper
plugs: SW103 for line 1, SW203 for line 2, SW303 for line 3, and SW403 for line 4.
3. Insert the RGLU2 (component side facing right) into the appropriate slot and apply firm, even
pressure to ensure proper mating of connectors. RGLU2 can be installed in place of RCOU,
per tables in Chapter 2 – DK40i Configuration.
4. After installing the RGLU2, gently pull the PCB outward. If the connectors are properly
mated, a slight resistance is felt.

Slot PCBs

RSIU, RSIS, RMDS
RS-232/Modem Interface Unit

Older Version(s): none

The RSIU is a standard plug-in type PCB that must be installed into the first universal slot of the
DK424 base cabinet. The RSIU PCB provides one standard RS-232 port (modular jack) when
ordered from the factory; this port can be configured in system programming to support any one of
the hardware options listed above.
The RSIU can be equipped with up to three more optional RS-232 ports (total of four RS-232
ports) or with two optional RS-232 ports and one modem port (total of three RS-232 ports and one
modem port). The optional RS-232 ports are provided by installing RSIS piggy-back PCBs onto
the RSIU PCB. The optional built-in modem is provided by installing an RMDS piggy-back PCB
onto the RSIU (see Figure 7-38 in Chapter 8 – DK40i/DK424 Universal Slot PCB Wiring).
The RSIS PCB can support any one of the hardware devices listed above via its RS-232 modular
jack. The RMDS PCB can function two ways: the RMDS can operate like an RSIS allowing it to
support any one of the hardware devices listed above locally from its RS-232 modular jack; or, the
RMDS can operate as a 1200 bps (bits-per-second) or 2400 bps system remote maintenance
modem.
The RMDS PCB function (modem or RS-232 port) is set in a system program option. The RMDS
can be set for one function only; it cannot support both functions simultaneously. When configured
as a modem, the RMDS PCB supports only the DK424 remote maintenance, ASCII terminal, or
DKBackup, and DKAdmin functions, and does not simultaneously support SMDI, SMIS, SMDR,
etc. (See Figure 8-36 on Page 8-37.)
The total bits-per-second (bps) data rate of the four RSIU, RSIS, RMDS (RS-232/modem) ports
combined cannot exceed 9600 bps. The RSIU, RSIS RS-232 ports can be individually set in
system programming to operate at 1200 bps, 4 ports max.; 2400 bps, 3 ports max.; 4800 bps, 2
ports max.; or 9600 bps, 1 port max.; or, any other combination that does not exceed 9600 bps. The
RMDS modem function can be set to operate at 1200 bps or 2400 bps; however, if the RMDS port
is used as a RS-232 port instead of a modem, it can also be set for 4800 bps or 9600 bps.
The TTY and modem function cannot operate on separate RSIU, RSIS, RMDS ports
simultaneously. If both functions are programmed at the same time on separate ports, the function
of the lowest numbered RSIU, RSIS, RMDS port (TTY or modem) will be active.The
communication parameters for all RSIU, RSIS, RMDS port function types except the SMDR are:
♦

Data word bits = 7

♦

Parity = even

♦

Stop bits = 1

The communication parameters for an RSIU, RSIS SMDR port is:
♦

♦

Parity = none

♦

Stop bits = 1

Only one RSIU can be installed per DK424 system. When the RSIU PCB is installed, the RSSU,
PIOU2, PIOUS2, IMDU modem, and PEPU PCBs can still be installed with all of their respective
paging, modem, and RS-232 port functions available; however, five RS-232/modem ports can be
installed in one DK424 system.
When installed together in the same DK424 system, the RSIU, PIOU2, PIOUS2, RSSU port
functions are identified and enabled (turned ON/OFF) in system programming. If the same
function is programmed for an RSIU port and a PIOU2, PIOUS2, RSSU port, only the RSIU port
will function.

RSIS, RMDS Piggy-Back Installation
1. Install all RSIS and RMDS PCBs on the RSIU PCB before installing the RSIU into the
DK424. Each RSIS or RMDS piggy-back PCB is installed on the RSIU PCB as shown in
Figure 4-38.
Up to three RSIS PCBs can be installed on the RSIU PCB; only one RMDS PCB can be
installed on the RSIU. The function and bit-per-second (bps) data rate of each RSIS and
RMDS circuit port is set in Program 76 as described in the Programming Part that follows.
2. After installing all RSIS, RMDS PCBs, install the RSIU into the DK424 per the following
instructions.

RSIU Installation
1. The RSIU must be installed only in slot 11 of the base cabinet (see Figure 7-23 to install the
RSIU PCB).
2. A PDKU or PEKU PCB must be installed in slot 12 of the base cabinet to support the
programming telephone.
3. The first 8-station ports (000-007) appear on the PDKU or PEKU as installed in slot 12. The
programming telephone will then be on the 6th circuit (port 005; or, 013 until Program 03
Code 49 is set for slot 11) of the PDKU in slot 12.
The function and bit-per-second (bps) data rate of the RSIU or RMDS, RS-232 circuit port is
set in Program 76 as described in the Strata DK Programming Manual.
All information provided in the “RSIU Installation” on Page 7-46 applies to installing an RSIU in
an existing system. Hence, most PCBs must be moved to the next highest slot.

➤ To move the PCB to the next highest slot
1. Identify (mark) the attendant console and all station PCB wiring connectors so they can be
removed and then reinstalled on the same PCB later (console station PCBs include: PDKU,
RDSU, PEKU, PESU, RSTU, PSTU and RATU PCBs).
2. Turn system power OFF.
3. Disconnect the connectors from the attendant console and all station PCBs listed in Step 1.
4. Remove all station PCBs listed in Step 1.
5. Install each PCB that was removed in Step 4 into the next highest empty station PCB slot
number. Skip over all other types of PCBs that were not removed. Example: If a PDKU was
originally in slot 11 and a PSTU was in slot 12, the PDKU is moved to slot 12 and the PSTU is
moved to slot 13. The programming telephone will then be on the 6th circuit (port 005; or, 013
until Program 03 Code 49 is set for slot 11) of the PDKU in slot 12.
6. Connect all PCB connectors that were removed back into the same PCBs they were removed
from in Step 3.
7. Turn the system power ON and note that the programming telephone is on port 13 and all other
ports are shifted up by eight ports. Program slot 11 with Code 49 and all other slots with the
appropriate codes using Program 91-1 and/or 03.
Next, cycle system power OFF (five seconds) and ON, or, run Program 91-2 to transfer
Program 03 data from temporary to working memory. At this time the programming telephone
changes from port 13 to port 005 and all other ports shift down by eight ports.

The steps in “RSIU Installation” on Page 7-46 apply to installing an RSIU into an existing
system. Hence, most PCBs must be moved to the next highest slot using the following
steps.

Note

1. Identify (mark) all PCB wiring connectors so they can be removed and then reinstalled onto
the same station PCB later.
2. Turn system power OFF.

DK40i/DK424 Universal

➤ To install an RSIU PCB into an existing system with DID and/or Tie lines

3. Disconnect the connectors from all PCBs except PIOU2, PIOUS2, RSSU, PEPU, RCIU, and
RCIS.
4. Remove all PCBs except PIOU2, PIOUS2, RSSU, PEPU, RCIU, and RCIS.
5. Each PCB that was removed must be installed into the next highest empty PCB slot number.
Skip over all other types of PCBs that were not removed.
This step may have to be modified for the RDTU PCB, depending on the configuration to
meet the requirements of RDTU slot assignments per tables in Chapter 6 – DK424 T1.

Note

6. Connect all PCB connectors that were removed back into the same PCBs from which they
were removed.
7. Turn the system power on and note that the programming telephone is on port 13 and all other
ports are shifted up by eight ports. Program slot 11 with Code 49 and all other slots with the
appropriate codes using Program 91-1 and/or 03.
Next, cycle system power OFF (5 seconds) and on or, run Program 91-2 to transfer Program
03 data from temporary to working memory. At this time the programming telephone changes
from port 13 to port 005 and all other ports shift down by eight ports.

RSIU, RSIS, RMDS Programming
Program 03: Programs slot 11 with code 49 to identify that the RSIU PCB is installed in slot 11.
Program 76-1X-Y: Assigns each installed RSIU port to a function. Where X identifies the RSIU
port no. 1~4 (see Figure 7-23 for RSIU port number configuration) and Y identifies the RSIU port
function:
♦

Y=1, RS-232 TTY (Program 77-1, LED 14 OFF)

♦

Y=1, RMDS modem (Program 77-1, LED14 ON)

♦

Y=2, SMDR

♦

Y=3, MIS or SMIS

♦

Y=4, SMDI

♦

Y=5, Open Architecture

♦

Y=0, No function - this should be used for any of the four RSIU, RSIS, RMDS ports that are
not used.

Notes
●

Strata DK I&M

Function codes set in Program 76-1X-Y will override RSSU, PIOU2, and/or PIOUS2 function
codes (41, 42, 43) set in Program 03.

The TTY and modem function cannot operate on separate RSIU, RSIS, RMDS ports
simultaneously. If both functions are programmed at the same time on separate ports, the
function of the lowest numbered RSIU, RSIS, RMDS port (TTY or modem) will be active.
When uploading Program 76-1 with DKAdmin or DKBackup, the data will not change until
the system power is cycled.

Program 76-2X-Z: Assigns each installed RSIU port to operate at a specified transmission rate.
Where X identifies the RSIU port no. 1~4 (see Figure 7-23 for RSIU port number configuration)
and Z identifies the RSIU, RSIS, RMDS port transmission rate in bits-per-second (bps).
Notes
●

●

The sum of the used RSIU, RSIS, RMDS ports transmission rates cannot exceed 9600 bps.
Ports assigned as “non-function” (code 0) in Program 76-2X-Y will not be included in the
transmission rate sum. The RMDS will only function at 1200 or 2400 bps.
When uploading Program 76-2 with DKAdmin or DKBackup make sure that Program 76-2
bps rate for the TTY/ modem port is set the same in: DKAdmin communications setup,
DKAdmin customer database, and any DK424 RCTU. If the bps rate is not the same in all
three areas, uploading will fail on Program 76

Program 77-1, LED 14: Enables the RMDS modem function. If the RMDS should function as a
modem, turn ON LED 14. If the RMDS should function as a RS-232 port, turn OFF LED 14.
Program 77-1, LED 15: Sets the RMDS communications standard type to CCITT/V.22bis (2400
bps) or Bell 212A (1200 bps). The standard set in this program must match the standard of the
modem communicating with the DK424 RMDS.
If the RMDS modem standard should be CCITT/V.22bis, turn LED 15 ON. If the RMDS standard
should be Bell 212A, turn LED 15 OFF. Most Hayes compatible modems will function with either
standard. Check with the modem manufacturer’s documentation to verify which protocol should
be used. When the system is initialized the Bell 212A standard is set (LED 15 OFF).
Program 77-4, LED 01/LED 02: Enables CLID, ANI, and/or DNIS information for ACD calls to
be sent from the RSIU OA port.
➤ Turn LED 01 ON if the OA port should send CLID and/or ANI information for ACD calls.
➤ Turn LED 02 ON if the OA port should send DNIS information for ACD calls.
Program 77-4 allows LED 01 and LED 02 to be turned ON simultaneously, allowing CLID, ANI,
and DNIS information to be sent from the OA port for ACD calls.
The system will initialize with LED 01 and 02 OFF–no CLID, ANI, or DNIS information will be
sent from the OA port for ACD calls.

Notes
●

●

For the system to recognize the DTMF tones generated by a standard telephone (or any other
device connected to a standard telephone port), a DTMF Receiver Unit (RRCS-4, -8, or -12)
must be installed on any DK424 RCTU or the DK40i K4RCU3.
Most standard telephones and two-wire devices require the 190V P-P level; however, some
devices may experience ring-trip with 190V P-P and should be set for 130V P-P.

See Figure 7-27 for an illustration of the PSTU1, PSTU2. Figure 7-28 shows the RSTU2. See

RMCU/RCMS
E911 CAMA Trunk Direct Interface
System:

DK424

Circuits per PCB: four circuits
Interfaces with:

enhanced 911 locator services

Older Version(s): none

The E911 CAMA Trunk Direct Interface card (RMCU) enables cost-effective connection to the
Enhanced 911 locator services without third-party equipment. Figure 7-31 shows the RMCU. The
RMCU supports two subassemblies (RCMS) that provide a total of up to four ports as shown in
Figure 73.
The RMCU has no CAMA circuits. It requires one RCMS subassembly to provide one or two
CAMA trunks and two RCMS PCBs to provide up to four CAMA trunks.
When RMCU code 19 is entered for a slot in Program 03, that slot assumes the next four
consecutive CO line numbers in the system. Only one RMCU PCB can be installed in a DK424
system. If more than one slot is programmed with code 19 in Program 03, the lowest slot having
code 19 will be the CAMA trunk active slot.
The controls, indicators, and connectors for the RCMS are listed in Table 90.
Location of the RCMS LEDs are shown in Figure 76.
Functions of the RCMS LEDs are given in Table 91.
A wiring diagram is shown in “RCMS Subassembly (stand-alone)” on Page 7-57.

RCMS Subassemblies Installation
1. Attach one or two subassemblies (RCMS) to the connectors on the RMCU as shown in Figure
7-29. If only one RCMS is to be installed, install it in the bottom position.
2. Apply firm even pressure to ensure that the connectors are properly seated in the RMCU
connector blocks. If they are seated properly, a light resistance is felt when you pull the units
away from the RMCU.

RMCU Installation
1. Insert the RMCU (component side facing right) into the appropriate slot, and apply firm, even
pressure to ensure proper seating of the connectors.
2. Gently pull the unit outward. If the connectors are properly seated, a light resistance is felt.
3. Wire the RCMS jacks, J4 and J5, to the network CAMA trunks per Figure 8-26 on Page 8-27.
4. Test the CAMA trunk and set the 3-dB PAD switches, SW101 and SW 201, for the appropriate
volume level.

DK40i/DK424 Universal
Slot PCB Wiring

This chapter contains point-to-point wiring diagrams for connection of telephones, lines,
peripheral equipment, and power supplies for the universal slot PCBs of both the Strata DK40i
Expansion KSU and DK424 systems.
Wiring diagrams are divided into groups according to the PCB which provides the interface for, or
controls the operation of, the associated equipment, as listed below:
♦

Station Wiring:
♦

Digital Stations

♦

Electronic Stations

♦

Attendant Consoles

♦

Analog Stations

♦

Power Failure Cut-through (DPFT) Pin-outs

♦

CO Line Wiring

♦

DID and Tie Line Wiring

♦

Option Interface PCBs

Note

Before using the Connect Record Sheets (following each Wiring Diagram), make copies
for future use.

Diagrams which apply to only one system (e.g., DK40i) are in the installation chapter which
relates to the system. Wiring diagrams appear at the end of these two chapters:
♦

Chapter 1 – DK14 Installation

♦

Chapter 2 – DK40i Installation

The RDTU cable connection information (DK424 only) is in Chapter 6 – DK424 T1.

1. 4-wire modular jacks such as graybar part number AA-104A-4 could be used in place of the two modular jacks; or,
a T-connector such as graybar part number 267A2 Adaptor could be used as shown below:
2. Assign RCIU1/RCIU2/RCIS circuits to the appropriate CO line using Program *50.

CAUTION!

RCIU1 cannot be used in DK40i. Install RCIU2 in slot 17 only of the
DK40i Expansion Unit; it must never be installed in slot 18.

Telephone Installation
This section describes the wiring required to connect telephones to the system. Before installing
any telephone wiring, read the following warning and caution notes:
WARNING!
➤ Never install the telephone wiring during a lightning storm.
➤ Never install the telephone jacks in wet locations, unless the jack is specifically
designed for wet locations.
➤ Never touch uninsulated telephone wires or terminals unless the telephone line has
been disconnected at the network interface.
➤ Use caution when installing or modifying telephone lines.
➤ If telephone, DSS console, door phone control box, or door phone wiring exits the
building, external secondary protection is required. See Chapter 8 – DK40i/DK424
Universal PCB Wiring.

When installing the station cable, do not run the cables parallel if they are
within three feet of an AC power line. AC power lines should be crossed at right
(90°) angles only. In particular, avoid running station wire pairs near devices
that generate electrical noise, such as neon or fluorescent light fixtures.

Important!

For DK14, see Figure 1-15 on Page 1-22, for DK40i, see Figure 3-24, and for
DK424, see Chapter 5 – DK424 Installation for station apparatus secondary
protection information.

System Connection
Digital Telephones
The following provides information on how to connect digital telephones to the DK system.
Note

Before proceeding, see warning and caution notes in “Telephone Installation”.

Digital telephones connect to the digital telephone ports via the MDF with standard twisted-pair
jacketed telephone cable. If using 24 AWG cable, single-pair wiring is sufficient in most cases for
digital telephones to operate effectively at up to 1000 feet from the system.
Digital telephones that are equipped with Integrated Data Interface Units or ADMs should have
two-pair (or external power) to function effectively at this distance. This also applies to digital
telephones supported by systems that must operate with battery reserve power – Chapter 5 –
DK424 Installation, Table 5-2 on Page 5-5.
To accommodate the digital telephone line cord, the cable should be terminated in a modular
station connector block (RJ-11) at the station location. The standard single-pair, modular digital
telephone cord that is sent with the telephone is 7 ft. (the maximum allowed is 25 ft.).
Note

9-4

Digital telephone cable runs must not have cable splits (single or double), cable bridges
(of any length), or high resistance or faulty cable splices.

Strata DK I&M

Station Apparatus
Telephone Installation

Electronic Telephones
The following provides information on how to connect electronic telephones to the Strata DK
system.
Before proceeding, see warning and caution notes in “Telephone Installation” on Page 9-3.

Note

Electronic telephones are connected to electronic telephone circuits in the DK40i Expansion Unit
on the Electronic Telephone Interface Unit (PEKU) and the Standard/Electronic Telephone
Interface Unit (PESU) via the MDF with standard twisted-pair jacketed telephone cable. Two-pair
wiring, as a minimum, is required for telephone connection. However, three-pair wiring is
recommended for some upgrades, such as OCA.
To accommodate the electronic telephone line cord, the cable should be terminated in a modular
station connector block (RJ-11) at the station location. The standard two-pair modular electronic
telephone cord length is 7 feet (the maximum allowed length is 25 feet). See Chapter 8 – DK40i/
DK424 Universal Slot PCB Wiring for more details.
If using 24 AWG cable, the overall length of the station cable run from the DK40i Base KSU to the
telephone must not exceed 1,000 feet (305 meters).

The following provides information on how to connect standard telephones to the DK system.
Before proceeding, see warning and caution notes in “Telephone Installation” on Page 9-3.

Note

Standard telephones connect to standard telephone circuits of the Standard Telephone Interface
PCBs: RSTU, RSTU2, RDSU/RSTS, PSTU, PESU, KSTU2 (DK40i only), and QSTU2 (DK14
only). Standard telephones connect to RSTU, RDSU/RSTS, PSTU or PESU via the MDF with
standard twisted-pair jacketed telephone cable. (See single-pair wiring Chapter 8 – DK40i/DK424
Universal PCB Wiring for more details.)

Station Apparatus

Standard Telephones

The standard telephone cable’s overall loop resistance, connected on- or off-premises, is 300 ohms
maximum, (for PSTU, PESU, KSTU2, or QSTU2), 600 ohms for RSTU and RDSU/RSTS with
-24VDC (no R48S), and 1200 ohms for RSTU and RDSU/RSTS with -48VDC (R48S installed on
RSTU, RSTU2, or RDSU PCB), including the telephone resistance. This also applies to all devices
connected to standard telephone circuits.
A standard telephone connected off-premises via the telephone network should interface with
OL13A, OL13B, or OL13C lines (or equivalent) and connect to an RJ21X, FIC jack or equivalent,
(see Chapter 8 – Universal Wiring Diagrams and Table 5-3, “DK424 Network Requirements” on
Page 5-6).

Telephone Wall Mounting

Digital Telephone Upgrades
This section describes how to upgrade and configure 2000- and 1000-series digital telephones for
features and options.
TAPI and Simultaneous Voice and Data Upgrades (RPCI-DI, PDIU-DI2 and PDIU-DI)
Both the 2000- and 1000-series digital telephones can be upgraded with an integrated data
interface unit to transmit and receive simultaneous voice and data calls. There are three versions of
the integrated unit:
♦

RPCI-DI and PDIU-DI2 for the 2000-series telephones

♦

PDIU-DI for the 1000-series telephones.

Asynchronous devices, such as PCs and terminals, can be connected to the standard RS-232
connector of the RPCI-DI or PDIU-DI2. Station users are able to transmit and receive RS-232 data
over the single-wire pair of the RPCI-DI or PDIU-DI2 equipped telephone.
TAPI/Data Communications Modes
The RPCI-DI can operate in two modes: the TAPI or the data communications mode. The mode is
changed by sending the appropriate control signal to the RPCI-DI from the PC to which the RPCIDI is connected.
TAPI Mode
In the TAPI mode, the PC connected to the RPCI-DI can place telephone calls. The PC can also
receive Caller ID, ANI, and DNIS information received by the RPCI-DI telephone. When in the
TAPI mode, the RPCI-DI is designed to be compatible with Microsoft TAPI application programs.

Station Apparatus
Telephone Upgrades

For more information, see Chapter 13 – Computer Telephony Integration. If an RPCI-DI only
needs to support TAPI (and not data–see Notes below) it can be connected to any digital telephone
circuit.
Data Communications Mode
In the data communications mode, data calls can be from a telephone with the 'DWD&DOO button
and disconnected with the 'DWD5HOHDVH button. Digital telephones can have a 0RGHP button
for reserving a modem or monitoring modem availability and status. These feature buttons are
assigned to telephones with Program 39. Data and voice calls can be dialed from a terminal or PC
using standard “AT” commands.
Notes
●

●

●

1000-series digital telephones with an RPCI-DI or PDIU-DI2 cannot be wall-mounted or
equipped with an Add-On-Module (ADM) or DVSU for Speaker OCA. A 2000-series digital
telephone with a PDIU-DI2 or RPCI-DI can support an HHEU at the same time, but cannot
support a DVSU or ADM and can be wall-mounted.
Only PDKU1 circuits 1~7 can support RPCI-DI or PDIU-DI2s; all PDKU2 and Base Unit
digital circuits can support PDIU-DI2 and RPCI-DIs.
RPCI-DIs and PDIU-DI2s that support data communications mode, must be connected to
digital telephone circuits that support 2B channels. The digital circuits that support RPCI-DI
data communication are:
DK14 – all digital telephone circuits.
DK40i – all digital telephone circuits except those installed in slot 17 and 18 of the expansion
unit.
DK424 – see Tables 4-4 and 4-5 of the Chapter 4 – DK424 Configuration.

RPCI-DI/PDIU-DI2 Installation
See Figures 9-2, 9-5 and 9-6 and follow these steps:
1. Loosen the four screws on the digital telephone base and remove the base.
2. Insert the two integrated unit wire plugs into the connectors on the PCB in the telephone
(observing the red wire for correct positioning).
3. Attach the integrated unit to the bottom of the phone. Install the PDIU-DI for 1000-series;
install PDIU-DI2 or RPCI-DI for 2000-series phones. Secure with the four captive screws.
Note

RPCI-DI V2s require some modification when installed in DKT versions 1~3; RPCI-DI
V2s in DKT version 4 or higher do not require any modification.

4. Remove the directory tray from the original telephone base and install it on the integrated unit
phone base. Squeeze the tray on its sides so it bows slightly to remove and re-install.
5. See Chapter 5 – DK424 Installation, Table 5-2 on Page 5-5 for loop limits. Install a two-pair

Loud Ringing Bell/Headset Upgrade (HHEU)
The Loud Ringing Bell/Headset upgrade (HHEU) enables an external speaker (HESB) for the
Loud Ringing Bell feature and/or a headset to be connected to both series of digital telephones.
Notes
●

●

●

●

●

There are two types of HHEUs: the HHEU1 (which has four versions, V.1~V.4) and the
HHEU2.
Both 2000- and 1000-series digital telephones require either an HHEU2 or a V.3 or V.4
HHEU1 for HESB operation; earlier HHEU1 versions are only sufficient for headset operation
only.
Only digital telephones equipped with an HHEU2 can be wall mounted. The HHEU2 is
identical to the V.4 HHEU1, except that the HHEU2 has longer wires to accommodate wall
mounting.
A Toshiba HESC-65A cable is required to connect the HHEU in a digital telephone to the
HESB.
1000-series digital telephones cannot be equipped with the HHEU (any type or version) and
the integrated data interface unit (PDIU-DI) at the same time, but 2000-series digital
telephones can support an HHEU and a RPCI-DI or PDIU-DI2 at the same time.

HHEU Upgrade Installation
See Figures 9-2 and 9-8~9-12 and follow
these steps:

Tips on Extending Battery Pack Life
All rechargeable nickel cadmium batteries can develop a “memory” (reduced charge capacity)
caused by repeated charge and discharge cycles. Batteries that have developed this effect do not
operate to their fullest capacity.
➤ To avoid memory effect
➤ Operate the unit until the battery pack is completely discharged before recharging. For
example, use the handset off the base all day. Only replace the handset on the base at night
after a full day of use. Do not “top off” the charge after using the battery for a short time.
➤ To erase memory effect
➤ Operate the unit until the battery pack is completely discharged, then recharge it fully. Repeat
this process at least three times.
LCD Low Battery Indicator
When the battery pack in the handset is low and needs to be charged you see this message on the
display and the handset beeps. Table 9-3 shows symptoms.

PC Attendant Console

PC Attendant Console
A Strata DK system configured with RCTUB2 or RCTUBA/BB can support two Attendant
Consoles, and systems with RCTUC1/D2 or RCTUC3/D3 can support four Attendant Consoles.
The RCTUA1, RCTUA3, RCTUB1, or RCTUC/D1 do not support Attendant Consoles.
PC and conventional Attendant Consoles require RCTUB2 or RCTUC/D2 R 2 processors or
RCTUBA/BB, RCTUC3/D3, RCTUE3/F3 R3 processors.
The PC attendant console (DK-PCATT) requires a customer-supplied, IBM-compatible PC. A
VGA or SVGA monitor and a COM port dedicated to the PC attendant console is required.
Toshiba recommends the following for the PC attendant console: Pentium processor/100 MHz, 16
MB RAM, 1.44 MB floppy drive, 200 MB hard drive, and a mouse. A tower that sits on the floor
is provides better monitor visibility (as opposed to a desktop model). Microsoft® Windows® 95
software must be resident on the PC. Windows 3.1 will work, but Windows 95 is recommended.
Important!

Hardware Installation
The RATU PCB can support up to four Attendant Consoles in any combination. (See “RATU

Station Apparatus
PC Attendant Console

PC Attendant Console Programming
Program 03: Code 51 assigns the RATU PCB attendant console cabinet slot number.
Important!

The RATU PCB takes up four station ports in software; each attendant console will
be assigned one of the ports in consecutive order. Toshiba recommends installing the
RATU PCB in the next highest slot number following the last station PCB installed–
do not skip slots. The first port number will be the next consecutive port number
following the last station port installed.

Program 15: If the attendant console is used to set-up trunk-to-trunk (two CO-line or tandem)
connections with loop start lines, set Program 15-5 appropriately; if the CO sends the AR-Hold
signal, set 15-0 and 15-3 to Detect. If the CO does not send the AR signal, set 15-0 and 15-3 to
Ignore. Loop start trunk-to-trunk calls remain on attendant hold loops only if AR-Ignore is set.
Program 58
58-1: Sets the attendant console overflow time for each console.

♦

58-2: Sets the console display for EL or CRT (EGA) and enables or disables console call
waiting tone for each console. (Not used for the PC attendant console).

♦

58-4: Sets the console Answer key priority for each console.

♦

58-5: Sets the console overflow destination for each console.

Program 59: Assigns attendant console Flexible Buttons (Keys) for each console.
Attendant Console Load Share Programming
Program 81~89: Assigns CO lines (loop, ground, and DID) to share the incoming call load
between consoles. (Tie lines load share on Dial “0” calls only, without the use of Programs 81~89.)
All incoming CO lines (including DID lines) to be distributed between two or more Attendant
Consoles should be assigned to ring each console in Programs 81~89.
Note

Station Apparatus

♦

Delay ring assignments do not apply to DID lines.

Program *09: Assigns the user company’s main listed [DN] (last four digits) to the attendant
console if DID lines should ring the console. If the DID lines are assigned to ring multiple
attendant console ports in Programs 81~89, DID calls will be distributed between the consoles.
Only one console (any one) should be assigned with the main listed [DN] in Program *09.
Programs 71 and 72: Can be used to provide an alternative assignment of DID calls using Program
*09. Program 71 assigns the dialed number to ring at different locations during each Night Mode
(Day, Day2, Night). DNIS tags can be added for personalized identification of calls. Program 72
provides external forwarding of calls listed in Program 71.
Program *17: Assigns each CO line to an attendant console as the DID line intercept position as
required. (Intercept calls do not load share.)
Attendant Console Load Share Programming Example
The user’s company DID line [DN] is 583-3700; this number and other loop start lines should ring
in a load sharing manner to each of the Company’s two Attendant Consoles in the Day, Day 2, and
Night modes.
Attendant consoles one and two are connected to RATU ports 024 and 025 respectively and should
load share 583-3700 calls and other CO line calls. Program the DK424 as shown below:
♦

In Programs 81, 84, and 87, assign all CO and DID lines to ring ports 024 and 025.

♦

In Program *81, *84 and *87, assign all CO lines to flash the [PDN] of port 024.

Line Settings
Each line and line group within the system can be renamed to allow for easy identification. For
example, a private line for John Smith can be marked “John’s Pvt Line”. These identifiers are
unique to the PC attendant console.
In the Lines dialog box, you can change the names that appear in the Active Call window. The
Active Call window names are different from the names that appear in the PC attendant console
selection windows.
The Attendant can also define a default line or line group to make dialing more efficient. The
default line or line group can be used with the Directory to identify a Tie line group for easy
transfer of calls. (See “Setting up the Directory” later in this section).
➤ To change CO line and names

Answer Prompts
Answer Prompts can be entered so that when new calls are presented and answered by the
Attendant, the prompts will appear in the information window. Any currently recorded prompts are
listed in the Answer Prompts box (shown below) and two selections on the left allow linking the
prompts to a DNIS tag or CO line.
Note

DNIS applies to R3 and up only.

The DK424 identifies calls to the Attendant position by using the default CO line indication. It can
also attach a tag that was recorded in Program 71 for each DNIS number translated by the system.
When lines are marked as DNIS in the Telephony Setup (see “PC Attendant Console Software
Installation” on Page 9-34), the PC attendant console uses the DNIS tag to select the prompt
instead of the line number. The button marked DNIS Text... is used to record the DNIS Tags which
should match those listed in Program 71-5.
Toshiba recommends entering DNIS tags when they are programmed into the DK system. This
enables the Attendant or System Administrator to create prompts as needed. Even if some DNIS
lines are not scheduled to ring at the console, the calls to be forwarded to the Attendant and
answers prompts may be used later.
The Answer Prompts can have approximately 110 characters. The edit window, shown below, is
the same size as the window on the main screen in order to view the message as it will display.

Setting up the Directory
The directory is a central part of the PC
attendant console. Information in the
directory is used for the following:
♦

Auto Dial

♦

Auto Transfer

♦

Transfers to Voice Mail

♦

Recording an individual’s status

♦

Recording messages for people
without phones or for transferring
to Voice Mail

♦

Recording individual’s work departments so that when a caller asks for someone in “Sales,” a
list of department members will appear

1038

This is also a place to store information about different individuals and how they may be reached,
for example, pagers, home office, car phones, fax, etc. It can also be used to indicate location,
work schedule and supervisors of people if needed.
Multiple entries of the same information is allowed.
For example, two people may share the same [DN]. A call to John Smith will ring station 204 and
if Sandy Johnson has the same [DN], her telephone will also ring. The same person may be entered
twice. For example, John Brady may be entered with [DN] 204 and with a [PhDN] 504.

Strata DK I&M

5/99

Station Apparatus
PC Attendant Console

When there are multiple entries, Auto Dial (includes Auto Transfer) is disabled. In the first
example, where two people shared the same [DN], the system would pause if the [DN] is entered.
At this point, the Attendant can enter a name and as long as there are no name conflicts, the
console will now Auto Transfer. When the system pauses, other calls can still be handled by Auto
Dial if there are no conflicts.
It is important to enter names in the same format, otherwise, the directory search function will not
work and the individual will have to be selected manually. In other words, avoid entering first
names for some people and first and last names for others. For example, if I created an entry for
Pat L and another for Pat Long, the first entry would never be selected because the console will
look for a match to Pat Long. If an “o” is entered after the “L”, the console will select Pat Long.
Avoid using abbreviations in the initial entry.
Use the “Dept” field for grouping people who need to be reached by function. Directory entries
with this field left blank will not show in the “Dept Select” feature. Assigning a consistent list
allows for all people within a group to show on the list together, offering the Attendant a method to
choose the person that can best serve the caller.
See the Strata DK PC Attendant Console User Guide for instructions on adding entries into the
Directory.
Establishing the Speed Dial List
The Speed Dialing list must be established before the list will show in the Dialing window. This
can be done in one of two ways.
Method 1
With the first method, you transfer a Speed Dial list that was previously entered into the DK
system to the PC attendant console. Once you have completed the following procedure, the PC
attendant console will store the numbers to match those stored in the system.Then, when the
Attendant uses this Speed Dial list, the PC attendant console dials the code for speed dial and the
DK system uses the number it has in memory.
➤ To transfer the DK Speed Dial list to the PC attendant console
1. If the Speed Dial list has been
entered into the DK system, then
select each speed dial entry.
2. Press the Modify button.
3. (optional) Enter a name for the
number.
Note

This name is stored in the PC
attendant console only and is
not downloaded into the DK
system Speed Dial Memo.

Method 2
With Method 2, you enter a list of
Speed Dial names and numbers from
the console. The entered list will
automatically re-sort and display

9-42

1039

Strata DK I&M

5/99

Station Apparatus
PC Attendant Console

alphabetically by name. A second sort is performed by dialed number which also searches for
names that are the same.
Do not enter extra spaces after either the first or last names and do not put the full name in only
one box. The system searches the names by putting together the First and Last name by adding a
space between the first and last.
The system also adds a comma and space after the last and before the first. The Attendant can type
names using either first or last name which will be automatically dialed if there is a matching
name, but the name must match exactly, including any spaces and commas.
[DNs] are treated as a separate match, thus calls proceed with either a [DN] or name match.
➤ To enter Speed Dial numbers
1. Enter each number and name from the console.
2. Click the Save button.
Using LCD Messaging
LCD Messaging uses the system messages and the personal messages (if enabled).

Backup/Restore Configuration
After all the data parameters are entered, the system should be backed up to a floppy diskette for
restoring the operation later if needed. This backup diskette can be used to set up additional PC
Attendant Consoles to operate with the same directory and settings as the first. This saves time
when creating additional consoles and ensures that the buttons and operation of one console
matches the next.

BGM Options
The BGM options allow music to play over optional external speakers (external page system) and/
or digital and electronic telephone speakers. BGM can be configured in three ways:
Configuration A – One Music Source
This configuration enables BGM and MOH to share the same music source (see Figure 10-3).
With this configuration, the MOH/BGM music source is connected to the RCA jack on the DK14
KSU, DK40i KSU or RCTU PCB. The music source is sent to CO lines/stations on hold, to
electronic/digital telephone speakers, and to the external page system via the PIOU, PIOUS, or
PEPU optional PCBs. Station Port 000 must dial  to send MOH over BGM and to
disable the option.

Configuration C – Three Music Sources
This configuration enables the MOH source to be connected to the RCA jack of the DK40i KSU or
DK424 RCTU (as in Configuration A). The digital or electronic telephone BGM source is
connected to a PEKU, PESU, KSTU2, RSTU, RSTU2, RDSU or PSTU PCB (as in Configuration
B), and a separate BGM source is sent to the external page speakers via the PIOU PCB (see Figure
10-6). This option is not available on DK14.
When a separate BGM source is connected to the PIOU, two customer-supplied amplifiers are
required to drive the external speakers.One amplifier drives the speakers for BGM when page is
idle and the other amplifier drives the speakers during page. The PIOU switches BGM or page to
the external speakers via zone relays. (The PIOUS and PEPU do not provide zone relays; therefore
Configuration C is not possible with these PCBs.)

Peripheral Installation
Music-on-Hold (MOH)/ Background Music (BGM) Options

➤ To install the MOH/BGM as BGM
1. Ensure that the MOH option is installed in accordance with “To install the MOH option” on
Page 10-4 (see Figure 10-2).
2. The output of the RCTU page/BGM control is applied through the backplane to the output
select switch (SW4) on the PIOU or PEPU. Set the SW4 switch to either SPO or SPI, as
required:
♦

SPO – Directs external page and non-amplified BGM to the HESB or external amplifier
(pins 13 and 38).

♦

SPI – Directs external page and BGM through the on-board 3-watt amplifier to the
external speaker output (pins 25 and 50).
The PIOUS provides non-amplified BGM/page output only (SPT and SPR). See Figure
10-8.

Note

3. When using an HESB or external amplifier for paging/BGM, adjust volume using the HESB
or amplifier volume control.
4. When using the internal amplifier for paging/BGM, adjust the volume using the volume
control (VR1) on the PIOU/PEPU PCB.

Alternate BGM Source Installation

➤ To connect the BGM source to the QSTU2, KSTU2, RSTU2/PSTU, RDSU, PEKU or PESU
See Figures 10-4~10-6 and follow these steps:
1. Access Program 10-2. If the BGM source is connected to circuit 3 on a PEKU, set LED 09 to
ON. If the source is connected to circuit 8 on a PESU, set LED 10 to ON. If connecting BGM
to QSTU2, KSTU2, RSTU2, RDSU or PSTU, LED 09 and 10 should be OFF.

Peripheral Installation

A BGM source can be connected to a station PCB (QSTU2, KSTU2, RSTU2/PSTU, RDSU,
PEKU, or PESU) to send music to all electronic/digital telephone speakers and to the external page
system via a PIOU, PIOUS, or PEPU. The BGM source is separate from the MOH source
connected to the RCTU PCB. An isolation transformer is needed to connect a music source to one
of the above standard telephone circuits (see Figure 10-4).

2. Using Program 19, identify (assign) the BGM slot.
3. If connecting the BGM source to a PEKU or PESU: Connect the PEKU tip and ring of circuit
03 to the 600 ohms or 8 ohms output of the BGM source or connect the BGM output to circuit
8 of a PESU.
...or
If connecting the BGM source to a QSTU2, KSTU2, RSTU2/PSTU or RDSU: Connect circuit
2 of the RSTU2/PSTU or RDSU to a customer-supplied isolation transformer and BGM
source.
Note

The isolation transformer protects the BGM source from potentially damaging QSTU2,
KSTU2, RSTU2/PSTU or RDSU voltage. Some music sources which are designed for
telephone system applications may have this protection built-in and do not require the
transformer. (Consult the documentation provided with the music source.)

4. If the BGM source is connected to either a W5 on the PEKU or W7 on the PESU PCB, cut the
strap. There is no strap to cut on the QSTU2/KSTU2, RSTU2/PSTU or RDSU.

5. Using the BGM source’s volume control, adjust the BGM volume to the desired level while
listening to BGM via a telephone speaker and/or the external page speakers. When BGM is
sent to external speakers via a PIOU or PIOUS or PEPU PCB, use the external amplifier
volume control to balance the BGM and page volume levels.

External BGM Installation
The external BGM options are closely associated with the external paging options. See “External
Page Options” on Page 10-26 for external paging amplifier installation.

Relay Control Options and Door Lock Control
Two relays are provided on the PIOU, PIOUS, and PEPU PCBs to control the operation of
peripheral equipment:
♦

External Page/Door Lock Relay

♦

Night Transfer/Music-on-Hold Relay

Note

Only the PIOU/PIOUS/PEPU with the lowest Program 03 code (41, 42, or 43) will
provide the relay control function.

Each relay can be configured to provide one of two possible control functions and as normally
open (MAKE) or closed (BREAK). Electrical specifications for the relay contacts are as follows:
Voltage: 24VDC maximum
Current: 1 amp maximum
CAUTION!

Note

To prevent relay damage, do not connect relays directly to 120VAC power
source.

See the Strata DK Programming Manual, as necessary, when instructed to program the
PIOU, PIOUS, or PEPU in the following paragraphs.

External Page/Door Lock Relay Options (PIOU, PIOUS, or PEPU)
The PIOU, PIOUS, or PEPU PCB may be programmed for either the external page function or the
door lock control function. (See Figures 10-7 and 10-8.)
When configured in Program 77-1 for the external page function, the relay controls an external
music source connected to the PIOU, PIOUS or PEPU to provide BGM over external speakers.
When a paging announcement is made over the external speakers, the external page relay mutes
the BGM.
When configured in Program 77-1 for the door lock control function, the relay controls an external
door lock. When a door lock button at a digital or electronic telephone is pressed, the door lock
control relay unlocks the door for three or six seconds, as specified in Program 77-1 (LED 20).

External Speaker Unit (HESB) Options

External Speaker Unit (HESB) Options
Strata DK systems provide three options utilizing an HESB:
♦

Loud Ringing Bell

♦

Amplified Speaker

♦

Talkback Amplified Speaker

System hardware requirements vary depending on the HESB option selected. See the following
installation procedures for the hardware requirements for each option.

Loud Ringing Bell Option
The loud ringing bell option enables the voice first or ringing signal tone to be amplified without
the use of other manufacturers’ equipment. The voice first and signal tone can be amplified on all
electronic and digital telephones equipped with HHEU PCBs and HESB. (See Chapter 9 – Station
Apparatus.)
The HESB automatically turns OFF once the ringing call or voice first has been manually
answered from the electronic or digital telephone. This turn-off feature prevents audio feedback
problems.
Installing the HESB Loud Ringing Bell in Digital Telephones
1. Connect a jumper between terminals 2 and 10 on the HESB TB1 terminal block (Figure
10-11).
2. Connect a jumper between terminals 4 and 5 on the HESB TB2 terminal block.

Two-CO Line External Amplified Conference

Night Ringing over Selected Page Zones
In systems shared by 1~4 tenants, each tenant’s CO lines can be assigned to night ring separate
PIOU external page zones. This feature can also be used in one-tenant systems.
With shared systems, for example, Tenant 1’s night ringing CO lines could be programmed to ring
PIOU external page zones 1 and 2, while Tenant 2’s lines could be programmed to ring zones 3
and 4. In non-shared systems, night ringing CO lines can be assigned to ring all of the zones or just
selected zones.
Note

For DK424 only: any RCTU provides four tenants.

Programming CO Lines to Ring Selected PIOU Page Zones
Program 78-1: Assigns CO lines, Tenant 1 through Tenant 4, that will night ring over PIOU
external page zones.
Program *15: Assigns CO lines to Tenant 1 through Tenant 4. Lines are initialized as Tenant 1.
Note

For DK424 only: RCTUA and RCTUB provides two tenants, RCTUC/D and RCTU E/F
provide four.

Program 77-3: Assigns Tenant 1 through Tenant 4 CO lines to night ring specific PIOU external
page zones.
Program 39: Assigns appropriate 1LJKW7UDQVIHU and 7HQDQW3LFNXS (for Tenant or NonTenant systems) buttons to electronic and digital telephones.
Note

Any station can pick up CO lines that night ring over external page zones by pressing the
[PDN] and dialing .

PIOU Zone Paging Installation
See “External Page Option Installation” on Page 10-26, paragraph 4 and Figure 10-17 for
installation instructions.

Two-CO Line External Amplified Conference
Customer-supplied two-way amplifiers can be installed to amplify two-CO line tandem (DISA,
External Call Forward) and/or conference calls. Amplified Conference is not available for the
DK14.

DK40i Information
Up to two amplifiers per Strata DK40i System can automatically connect to any two CO line
conference.

DK424 Information
As many as four amplifiers (4-RCTUB, C/D, and /F; 3-RCTUA) can be installed to support up to
four of these calls simultaneously. If three amplifiers are installed, three simultaneous calls can be
supported. If all amplifiers are in use, then subsequent two-CO line tandem calls and/or conference
calls will be unamplified. Each amplifier is connected to two designated PEKU station ports and
will automatically be switched into a two-CO line connection established between any CO lines in
the system.

Two-CO Line External Amplified Conference

Amplified Talk Path
Figure 10-19 provides a functional diagram of a two-CO line amplified conference connection. (A
tellabs 7206 amplifier is used here.) The talk path for the connection is as follows: outside party 1
– public telephone network – CO PCB, CKTX – RCTU – PEKU, port A – into AMP, Line in, –
AMP, Line out – PEKU, port B – RCTU – CO PCB, CKTY – public telephone network – outside
party 2. This path is two-way so when outside party 2 talks, the talk level is amplified in the
reverse direction.
Note

Only the outside party 1 talk path is amplified to/from a system telephone when it is
connected into a two-CO line conference.

Amplifier Requirements
♦

Customer-supplied amplifier (two maximum for DK40i and four maximum for DK424).

♦

Must be FCC-registered, Part 68, and must provide automatic gain control.

♦

Each amplifier requires two PEKU station ports.

♦

See the amplifier manufacturer’s installation documentation for amplifier grounding
instructions.

➤ To connect a two-way amplifier to the Strata DK system
1. At the MDF, connect the voice pair (VT, VR, port A) of circuit 2 on the designated PEKU
PCB to one input of the customer-supplied two-way amplifier. In the example in Figure 10-19,
this is CKTA (CO Side A) of the amplifier. (See the Amplified Two-CO Line Conference
wiring diagram in Chapter 8 – DK40i/DK424 Universal Slot PCB Wiring.)

3. Plug the amplifier’s power cord into the 117VAC (standard) wall outlet.
4. Set the gain and other amplifier parameter options per the amplifier manufacturer’s installation
documentation.

Amplifier Programming
♦

Program 10-1: LEDs 19 and 20 must be ON.

♦

Program 10-2: LED 18 must be ON.

♦

Program 10-3: Enables the appropriate PEKU PCB ports for amplifier connection. Only
enable the ports that will be connected with the amplifier(s).

♦

Program 15-5: Enables appropriate CO lines for Two-CO line tandem connection.

Note

♦

Strata DK I&M

Peripheral Installation

2. At the MDF, connect the voice pair (VT, VR, port B) of circuit 3 on the designated PEKU PCB
to the other input of the amplifier. In Figure 10-19, this is CKTB (subscriber side B) of the
amplifier.

LED 19 in Program 10-1 should be ON if it is certain that an amplifier will always be
available for two-CO line conference connections (four maximum, simultaneously). If this
LED is ON and a two-CO line connection is established without an external amplifier, the
Strata DK424 station may be unbalanced and may receive a hum noise. LED 19 provides
additional station amplification when external amplifiers are switched into two-CO line
connections.

Program 78-2: Enables appropriate CO lines if amplified DISA is required.

SMDR Printer/Call Accounting Device Options

SMDR Printer/Call Accounting Device Options
An SMDR printer or call accounting device may be connected to the system to provide a hardcopy record of station activity. The Strata DK system can record incoming, outgoing, and
transferred calls, as well as Account Code entries and names and telephone numbers of answered
DNIS, ANI, Caller ID, E911 and ISDN calls. Call record data is printed out at the completion of
each eligible call. SMDR format is ASCII-formatted, 8-bits, no parity, 1-stop bit.
To support the SMDR printer/call accounting device option, a Strata DK system must be equipped
with a PIOU, PIOUS,...or
♦

For DK424 only, a RSIU/RSIS, PIOU, and PIOUS

♦

For DK40i only, TSIU

♦

For DK14 only, WSIU

Connection of the printer or call accounting device to the PIOU, PIOUS, RSIU/RSIS (DK424),
TSIU (DK40i), or WSIU (DK14) PCB is accomplished with a 3-pair modular cord (seven feet
maximum) and a PPTC connector adapter (Figure 10-21, “PIOU/PIOUS SMDR Cable
Connections”).
Note

PIOU, PIOUS will be 300 or 1200 bps (see Chapter 7 – DK40i/DK424 Universal Slot
PCBs); RSIU/RSIS (DK424), TSIU (DK40i) and WSIU (DK14) can be 1200~9600 bps
(see Program 76).

Note

If PIOU, PIOUS, RSIU/RSIS (DK424) or TSIU (DK40i) are assigned as SMDR
simultaneously in programming, RSIU/RSIS or TSIU will operate as SMDR – not PIOU,
PIOUS. A display of the customer database (Figure 10-22 on Page 10-41) can also be
printed using the SMDR RS-232 port by running Program 97.

Peripheral Installation

The PIOU, PIOUS, RSIU/RSIS (DK424), or TSIU (DK40i) contain a call record buffer which
stores call record data (up to 50 calls) when the printed or call accounting device is turned OFF, or
when no device is connected to the SMDR port. No further call records are stored after the buffer
is filled. When the printer or call accounting device is made operational, “ERROR BUFFER
OVERFLOW” prints out to indicate the buffer was full, and that some call information may have
been lost.

To program SMDR, use Program 60. The SMDR port is active only on the PIOU or PIOUS with
the lowest Program 03 code (41, 42, or 43), or the RSIU or RSIS Port programmed with code x2 in
Program 76-1.
SMDR sends out special names for the following types of calls:
♦

MSS – Prints on DISA and External Call Forward calls to stations. MSS prints only on DISA
calls that are answered after the threshold time (set in Program 60-2). If the call is answered
before the threshold time, the call will register as a normal incoming call and the MSS/transfer
portion of the call will not print out.

Note

The call threshold time – the length of time that a call must be in progress before it is
registered by SMDR – can be set for either 1.0 or 10 seconds in Program 60-2.

♦

MODM – Prints on calls to the RMDS or IMDU remote maintenance modem (Station #19).

♦

DISA – Prints on DISA and External Call Forward calls in which CO lines are accessed for
trunk-to-trunk outside calling.

Voice Mail Options

Voice Mail Options
Strata DK systems can support a Toshiba Stratagy, Stratagy DK, VP or customer-supplied voice
mail system.
Voice mail systems connect to standard telephone circuits (QSTU2, KSTU2, RSTU2, RDSU/
RSTS, PSTU or PESU). The number of circuits required by each device depends on the
customer’s voice mail requirements, such as the number of voice mail users. To support voice
mail, DK14 KSU must have QCRU3 installed, DK40i KSU must have K4RCU3 or K5RCU
installed and a DK424 RCTU must have an RRCS installed.
Voice mail integration is provided by Strata in-band tones and/or on DK424 (only) the Simplified
Message Desk Interface (SMDI) output of the PIOU, PIOUS, RSSU, RSIU, or RSIS SMDI port.
The PIOU/PIOUS/RSSU must be set with Program 03, code 43 or for RSIU/RSIS Program 03,
code 49 and Program 76-1 with code x4 to provide SMDI output. See the SMDI section for more
details about SMDI installation and operation.

Toshiba Stratagy, Stratagy DK, or VP Voice Messaging Systems
Strata DK systems are designed to support the full range of features offered by the Toshiba
Stratagy and/or VP systems. It provides various call routing, message handling, and information
management features, including:
♦

Auto Attendant

♦

Call Forward to Voice Mailbox

Answer (A) Tone
The Strata DK stations send an answer tone to Stratagy or VP when the station answers a VP or
Stratagy call.
Disconnect (D) Tone

Peripheral Installation

Some features of Strata DK system programming were designed for Toshiba Stratagy, Stratagy DK
or VP systems, and do not necessarily apply to customer-supplied voice mail messaging systems.
These programming features are:

The Strata DK stations send a disconnect tone to Stratagy or VP when the station hangs up while
connected to Stratagy or VP. [(D Tone is also sent to release the Stratagy or VP/Auto Attendant
port when an outside loop start CO line caller hangs-up and the CO provides a Calling Party
Control (CPC) or Auto Release (AR) disconnect signal per Program 15-0 and 15-3. Ground start
CO lines will send “D” tone to VM ports anytime an outside caller hangs up.]
Notes
●

●

●

Strata DK I&M

D Tone will not operate in all areas, because some COs fail to provide the CPC or AR signal
on loop start lines.
Both A and D Tones provide more efficient Stratagy or VP port use. Always enable these
options. Both options are enabled by accessing Program 31, and setting LED 15 ON.
The CPC or AR signal of some COs is not reliable and may occur during a CO line voice
connection, causing the call to disconnect. If this occurs, disable CPC /AR Hold and CPC/AR
Voice Mail calls on all CO loop start lines with Programs 15-0 and 15-3.

Voice Mail Options

Recall (B) Tone
Stations send a recall (B) tone to Stratagy or VP whenever Stratagy or VP answers a transfer
(camp-on) recall from stations that did not answer a Stratagy or VP blind transfer. (The B tone
notifies Stratagy or VP that the call is a recall and not a new call, allowing Stratagy or VP to
respond with the appropriate greeting.) For this feature to operate, QSTU2, KSTU2, RSTU2,
RDSU/RSTS, PSTU or PESU voice mail ports must have LEDs 19 and 20 turned ON in Program
31.
See “General Voice Mail (Standard Telephone Port) Programming” below for more information.

Customer-supplied Voice Mail Messaging Systems
Strata DK systems are designed to support a wide range of customer-supplied voice mail
messaging systems. Depending on the voice mail system used, some of the features available with
Toshiba Stratagy or VP (See “Toshiba Stratagy, Stratagy DK, or VP Voice Messaging Systems” on
Page 10-42) may be available with the customer-supplied system.

General Voice Mail (Standard Telephone Port) Programming
Voice mail (VM) QSTU2, KSTU2, RSTU2, RDSU/RSTS, PSTU or PESU port programming is
accomplished using Programs 31 and 10-2. (See Strata DK Programming Manual for more
details.) VM programming features are as follows:
VM Groups
This feature groups VM QSTU2, KSTU2, RSTU2, RDSU/RSTS, PSTU or PESU ports together so
that message waiting set/cancel signals appear to originate from the lowest port in the VM group.
All VM ports connected to a particular VM machine should be set in the same VM group (Program
31, LEDs 05~08). The same ports set in the Program 31 VM group should also be set in the
designated VM Distributed Hunt Group in Program *40.
Message Waiting (MW) Set/Cancel
If the VM machine has the ability to dial a code and the appropriate station numbers to set or
cancel the message waiting LEDs on digital and electronic telephones, you can use Program 10-2,
LED 04 to instruct the VM machine to set or cancel a MW LED. See the Strata DK Programming
Manual for more information.
Note

Only dial codes  and  are set in the VM device configuration; the VM device dials
the station number automatically to set/cancel the MW LED.

No Conference VM
Prevents undesired three-party connections during VM call transfers. All VM ports should be set
for No Conference (Program 31, LED 09).
Privacy Override Deny
Prevents stations from overriding (breaking in) in-progress VM calls (Program 31, LED 18).
End-to-End Signaling
Enables VM port DTMF operation. All VM ports should be set for end-to-end signaling (Program
31, LED 17).
Note

10-44

The RRCS -4, -8, or -12 must be installed on the DK40i or DK424 RCTU to enable Endto-End Signaling.

Voice Mail System Installation
1. Ensure that the QSTU2, KSTU2, RSTU2, RDSU/RSTS, PSTU or PESU PCB is installed in
the system per Chapter 7 – DK40i/DK424 Universal Slot PCBs.
2. Connect the VM system to the selected KSTU2, RDSU/RSTS, RSTU2, PSTU or PESU
standard telephone port. (See Chapter 8 – DK40i/DK424 Universal Slot PCB Wiring Chapter
3 – DK40i Installation or Chapter 1 – DK14 Installation.)
3. Program the Strata DK system for the required VM features. (See “Toshiba Stratagy, Stratagy
DK, or VP Voice Messaging Systems” on Page 10-42, paragraph 3 and “General Voice Mail
(Standard Telephone Port) Programming” on Page 10-44.)
4. For DK424, ensure that an RRCS -4, -8 or -12 is installed on the RCTU, and verify that the
RCTU code in Program 03 is for RRCS operation.
...or
For DK40i, K4RU3 is installed on the KSU.
For DK14, QRCU is installed.
5. Perform additional VM system programming as applicable (See customer-supplied
installation/programming manuals).
Note

10-46

Some VM devices may ring trip when called; in this case, set the square-wave ring voltage
jumper to L (low position) on the PSTU2, KSTU2, PESU or PSTU2 PCB connected to the
VM device. This is not necessary on RSTU2 and RDSU/RSTS PCBs because they have a
sine-wave ring generator.

Peripheral Installation
PC/Data Communications Interface Units

PC/Data Communications Interface Units
The Strata DK supports two types of Data Interface Units (DIUs) that enable digital telephone
users to simultaneously transmit and receive data on the same digital station port and wire pair
while communicating on a voice call.
One unit, called the integrated DIU (RCPI-DI, PDIU-DI/PDIU-DI2), becomes part of the digital
telephone, replacing the telephone’s base; the other unit, is a small self-contained unit called the
stand-alone DIU (PDIU-DS). Each RPCI or PDIU is powered by the digital port to which it is
connected (see Figure 8-3 on Page 8-4 for wiring requirements).
The RPCI-DI can operate in two modes: Telephony Application Program Interface Mode (TAPI)
or Data Communication mode. The RCPI operating mode is controlled by the PC connected to the
RPCI-DI. This section only covers the RCPI-DI data communications mode. See the PC/DIU User
Guide for information on changing the RPCI-DI mode.
Notes
●

●

“Digital Ports” include the PDKU and RDSU digital station ports.
2000-series digital telephones require RPCI-DI or PDIU-DI2 and 1000-series telephones
require PDIU-DI and are not compatible with RPCI-DI or PDIU-DI2.

Both RPCIs and DIUs can be connected to standard Electronic Industries Association (EIA) RS232 asynchronous serial data devices. EIA devices are divided into two categories: data
communication equipment (DCE) and data terminal equipment (DTE). Common DCE devices are
modems and some printers; common DTE devices are personal computers, ASCII terminals, and
some printers.

When in the data communications modes, RPCIs and DIUs can function with DCE and DTE
devices at data speeds of up to 19.2 kbps. However, keyboard dialing using AT commands (from a
PC or terminal connected to a RPCI or DIU) is limited to 9600 bps. RPCI or DIU data
transmission speed is set by the first AT command that the RPCI or DIU receives once it is in the
command state; if manual dialing or receiving calls in the auto answer (default) mode, the
transmission speed is transparent and can be up to 19.2 kps.
Important!

Strata DK I&M

5/99

Peripheral Installation

The RPCI-DI and PDIU-DI operate like a DCE and connect directly to DTE devices using
standard RS-232 cables. Depending on how its internal jumper plugs are configured, the PDIU-DS
can either operate like a DTE and connect to DCE devices; or operate like a DCE device and
connect to DTE devices. In most applications, DTE and DCE devices exchange data between each
other via the standard RS-232 cable connection.

To use the RPCI-DI, PDIU-DI or PDIU-DS with AT commands, communications
software or a PC program that performs terminal emulation must be used. AT
commands cannot be issued from the computer’s operating system prompt.

10-47

Peripheral Installation
PC/Data Communications Interface Units

RPCI-DI Dual Mode
RPCI-DI can operate in the data communication or Telephone Application Program Interface
(TAPI) mode.
♦

When in the Data Command mode, send the HEX (fØ), enter ALT (Hold) + 240 to the RPCI to
switch it to the Data Communications mode. (Unplugging the telephone cord and then
reconnecting it also resets the RPCI to the Data Communications mode.)

♦

When in the TAPI mode, send (ATCØ) to the RPCI to switch it to the Data Command mode.
In the TAPI mode, a constant stream of data is sent from the RPCI to the PC COM port.

♦

RPCI-DI mode switching should be performed automatically by the application programs
running on the PC connected to the RPCI-DI.

(See Chapter 13 – Computer Telephony Integration for instructions on configuring your PC for
TAPI software.)

Common DIU Connections
The block diagram in Figure 10-24 illustrates common RPCI and DIU data communications
connections. In this example, RPCI-DIs or PDIU-DIs are connected to PCs (PC1 and PC2), and
PDIU-DSs are connected to a serial printer and modems. PC users can transfer files internally,
print files on the same printer, and access the modem pool to send/receive data to/from an external
personal computer or dial up data service.
To access these devices, a data call connection must be established between the RPCIs and DIUs.
This is accomplished by dialing the destination DIU from a digital telephone dial pad or from a PC
keyboard using standard AT dial commands. RPCI-DIs and PDIU-DIs share the same intercom or
[PDN]/ports with the digital telephone to which they are connected, while PDIU-DSs have their
own. The intercom and data call LEDs on the digital telephone initiates a voice or data call,
respectively. When dialing from a keyboard with AT commands, ATD is typed for voice calls, and
ATDD for data calls.
Installation instructions for these devices are provided, starting from “RPCI-DI, PDIU-DI, PDIUDS SW1 DIP Switch Information” on Page 10-60 through “PDIU-DS Disassembly and
Assembly” on Page 10-65. Call paths and scenarios for five types of data test calls are provided in
“RPCI-DI/PDIU-DI/PDIU-DS Data Communication Installation Tests” on Page 10-66, paragraph
2 through paragraph 6. Step-by-step data calling procedures are provided in the PC/Data Interface
User Guide.

EIA Interface Leads (Signals)
Both DIUs operate with 10 standard EIA RS-232 interface leads (signals) on which signaling data
is transmitted and received. RPCIs and DIUs connect to serial data devices with standard RS-232
cables, available from telephone supply stores (see Figures 10-24~10-29 and 10-31). The RPCIDI/PDIU-DI/PDIU-DS requires 10 signals for some applications, but can function with eight using
modular cords and connectors with RJ45/DB25 adapters for other applications. If uncertain which
signals are necessary for an application, all 10 should be connected.
See Figure 10-33, “RPCI-DI, PDIU-DI, PDIU-DS SW1 DIP Switch Information” for more
information.
Important!
♦

The RPCI-DI and PDIU-DI is always a DCE device; the PDIU-DS may be a DTE or DCE,
depending on how its internal jumpers (1~9) are configured.

♦

In the descriptions below, when a signal is ON, its potential is about seven volts positive
relative to signal ground (pin 7); when a signal is OFF, it is about 7 volts negative relative to
the signal ground (pin 7).

Frame Ground (FG, Pin 1)
The FG signal (EIA circuit AA) is a protective or safety ground which is bonded to the PDIU-DI/
PDIU-DS PCB. If required by local codes, the FG should be connected to external ground.
Signal Ground (SG, Pin 7)
The SG signal (EIA circuit AB) establishes the common ground reference for all other PDIU and
data device signals and must be wired for all applications.
Transmit Data (TD, Pin 2)
DTE devices transmit and DCE devices receive data on the TD lead (EIA circuit BA). Before the
DTE device can transmit the TD signal, the RTS, CTS, DSR, and DTR signals (all discussed
below) must be ON. The TD signal is OFF in the idle state.
Receive Data (RD, Pin 3)
The DCE device transmits data to the DTE device on the RD lead (EIA circuit BB); the DTE
receives data on the RD.
Request to Send (RTS, Pin 4)
Some DTE devices send an RTS signal (EIA circuit CA) to the DCE device when they are ready to
transmit data on the TD lead. If the DTE device does not generate the RTS signal, the DIU DIP
switch SW1-4 should be set ON to inform the RPCI or DIU. Sometimes, the DTE/DCE device
may use RTS/CTS for Ready/Busy type flow control, in these cases DIP switch SW1-4 should be
OFF.

10-50

Strata DK I&M

5/99

Peripheral Installation
PC/Data Communications Interface Units

Clear to Send (CTS, Pin 5)
The DCE device sends the CTS signal (EIA circuit CB) which indicates that it is prepared to
transmit data to the line side. The DCE device sends this signal only when it receives the RTS
signal from the DTE device. Sometimes, the DTE/DCE device may use RTS/CTS for Ready/Busy
type flow control; in these cases, DIP switch SW1-4 should be OFF.
Data Set Ready (DSR, Pin 6)
When connected to the communication channel and prepared to exchange control characters to
initiate data transmission, the DCE device sends the DSR signal (EIA circuit CC) to the DTE
device. If the PDIU DIP switch SW1-2 is set ON, DSR will be ON continuously; if the switch is
set OFF, DSR follows DTR (if DSR is ON, DTR is ON, etc.) SW1-2 should be OFF in most cases.
Data Carrier Detect (DCD, Pin 8)
The DCE device sends the DCD signal (DCD, Pin 8) when receiving the carrier signal on the line
side. Before transmitting or receiving data, most DTE devices require that the DCD be ON. If the
carrier signal is removed by the remote end or lost due to a fault condition on the line, the DCE
notifies the DTE device by an OFF condition with the DCD signal. The PDIU DIP switch SW1-2
is set ON to set the DCD ON continuously. If set OFF, the DCD signal will only be ON when
connection between two DIUs is established and OFF when a connection is not established. SW12 is set OFF when the DTE/DCE uses the DTR/DSR signals for Ready/Busy flow control.
Data Terminal Ready (DTR, Pin 20)

Ring Indicator (RI, Pin 22)
The RI signal (EIA circuit CE) is sent by the DCE device to the DTE device. Whenever the DCE
device receives a ringing signal on the line side, it turns the RI signal ON. If RPCI or DIU DIP
switch SW1-3 is set ON, the RI signal will be continuously ON if ringing; if the switch is set OFF,
the RI signal will be one second ON/three seconds OFF when the RPCI or DIU detects ringing
signal.

Strata DK I&M

5/99

Peripheral Installation

The DTE device sends the DTR signal (EIA circuit CD) to the DCE device, prompting the DCE
device to open the communication line. The line is closed and the call disconnected when the DTE
device quits sending the DTR signal. DTR may be sent any time to indicate that the DTE is ready
to transmit or receive data. DIP switch SW1-2 should be set OFF in most cases.

Modem receives data on pin 2 (TD) and transmits data on pin 3 (RD).
The PDIU-DS must be in the Connect to Modem mode (P1~P9 strapped B-C) so that it transmits data
on pin 2 (TD) and receives data on pin 3 (RD).
For the above cable modifications, modem AT commands, and Program 20 settings are required for
proper call release when modems disconnect. With this configuration, the PDIU-DS “READY” light
will not light until modems at both ends establish communication (DCD is detected)

●

●
●

Never use modular cords and adapters when connecting a RPCI-DI/PDIU-DI/PDIU-DS to a modem.
Connection examples 1 and 2 work when using the RPCI-DI or PDIU-DI to make calls with personal computer applications
(auto-dialers, printer sharing, outgoing modem calls, etc). If the PC RPCI-DI or PDIU-DI must receive calls, the RI lead is
normally required; therefore, a standard RS-232 cable must be used (see Figure 10-24 on Page 10-49 and Figure 10-27 on Page
10-54).
In Connection Example 3, PDIU-DS must be in the connect to DTE mode (P1 ~ P9, strapped A-B).
All modular cords and adapters are customer-supplied.

DIP Switch Options
The RPCI-DI, PDIU-DI and the PDIU-DS each have a four-control DIP switch which can be
configured for signaling options. The switch is located on the bottom of the PDIU-DI, and on the
back panel of the PDIU-DS (see Figure 10-33).
SW1-1
Normally, this switch is set ON to disconnect devices from RPCIs or DIUs automatically. The
connection is maintained if data is exchanged between the device and the RPCI or DIU within
eight to nine minute intervals. If SW1-1 is OFF on the called and calling DIU, data calls will
remain connected until released manually.
SW1-2
This switch is placed in the ON position when the RPCI-DI or PDIU-DI (or PDIU-DS configured
like a DCE) must hold DCD and DSR ON continuously. If SW1-2 is OFF, DSR follows DTR and
DCD will be ON only when the DIU is connected on a data call to another DIU. SW1-2 should be
OFF on a RPCI DIU when it is connected to a personal computer that uses a communications
software program to establish data calls with AT commands; and whenever PDIU-DS is connected
to a modem.
SW1-3
The RPCI-DI or PDIU-DI (or PDIU-DS configured as a DCE) sends the Ring Indicate (RI) signal
to the computer to tell the computer (DTE) that the RPCI or PDIU is receiving an incoming call.
SW1-3 should be ON for the DIU to send RI steady, and OFF to send at one second ON/three
seconds OFF intervals.

This switch is placed in the ON position if the computer does not output the RTS signal or when
connected to a modem that tracks the DCD signal (modem set with AT&C1). Sometimes, the DTE
device may use RTS/CTS for Ready/Busy flow control, in these cases SW1-4 should be OFF.
In this case the DCD signal of the calling DTE is used as the RTS lead of the called DTE and the
DCD signal of the called DTE is used as the RTS signal of the other DTE. In this case a signal
which stops the DTE from transmitting data (usually the CTS lead) should be cross-connected to
the RPCI’s or DIU’s DCD signal. Consult the DTE device or application software documentation
to determine which type of flow control is required. If the DIU-DS is connected to a modem that
tracks carrier detect (AT&C1) SW1-4 should be ON.

RPCI-DI and PDIU-DI to PC Installation
The RPCI-DI and PDIU-DI always functions as a DCE device; it transmits data on the Receive
Data lead (RD) and receives data on the Transmit Data lead (TD). Most personal computers
function as a DTE device; PCs transmit data on the TD lead and receive data on the RD lead.
Note

The RPCI-DI or PDIU-DI can connect to a DCE computer or any other DCE-type device
using a specially configured RS-232 cable or adapter; but this application is rarely
required.

➤ To install the RPCI-DI or PDIU-DI to a DTE device, PC, or ASCII terminal
1. Install the digital telephone that is to be equipped with RPCI-DI or PDIU-DI per the
instructions in Chapter 9 – Station Apparatus and the drawing in Chapter 8 – DK40i/DK424
Universal Slot PCB Wiring.
2. Install the RPCI-DI or PDIU-DI under the digital telephone per the instructions in Chapter 9 –
Station Apparatus.
Note

The RPCI-DI or PDIU-DI always operates as a DCE device; therefore, unlike the PDIUDS, it has no internal jumpers.

3. Connect the appropriate RS-232 cable between the RPCI-DI or PDIU-DI’s DB-25 female
connector and the PC’s appropriate asynchronous serial communications port connector
(COM port).
Important!

4. Set the RPCI-DI or PDIU-DI DIP switch (SW1-1~4) for the desired application. See Figure
10-33, “RPCI-DI, PDIU-DI, PDIU-DS SW1 DIP Switch Information”.
RPCI-DI and PDIU-DI Programming

Peripheral Installation

Check the PC manufacturer’s serial communication port interface documentation
for correct RS-232 pin requirements; requirements vary with each manufacturer.
The number of EIA RS-232 signals required (8, 9, or 10 wires) depends on the
application. When EIA signal requirements are not known, connect the 10 EIA
signals listed in “EIA Interface Leads (Signals)” on Page 10-50. Figures 10-33 and
10-31 provide diagrams for connecting RS-232 cables between PDIU-DIs and PCs/
Toshiba portables.

Configure the RPCI-DI or PDIU-DI for DTE-type connection in Program 20 and the data button
assignments of the digital telephone connected to the PDIU-DI in Program 39.
♦

Strata DK I&M

assign '66 buttons to data devices; '66 buttons are used for voice calls only.

PDIU-DS to Printer Installation
Strata DK enables serial printers (laser, dot matrix, or other types) to be connected to stand-alone
data interface units (PDIU-DSs). Digital telephones equipped with RPCI or PDIU-DIs can share
access to these printers. Serial printers operate as DCE or DTE devices, depending on the vendor;
the PDIU-DS can be connected to either type, since it can be configured as a DTE or DCE device.
(The PDIU-DS comes from the factory configured as a DCE device.)
➤ To connect the PDIU-DS to a serial printer
Notes
●

●

Only serial printers (not parallel) that conform to EIA RS-232 signaling requirements can be
connected to PDIU-DSs.
In rare applications, it may be desired to connect printers to PDIU-DIs. See the printer’s
installation instructions.

1. Consult the serial printer’s documentation and determine if the printer operates as a DCE or
DTE device. Also, see Figures 10-32 and 10-34.
If the printer is a DCE device: Disassemble the PDIU-DS and configure it to operate like a
DTE device by placing the jumper plugs (P1~P9) in the “B-C” (MODEM) position.
Reassemble the PDIU-DS, and mark “B-C” on the bottom label for future reference.
If the printer is a DTE device: You may not need to disassemble the PDIU-DS, since it comes
factory-direct configured as a DCE device. However, if uncertain, disassemble the PDIU-DS
and verify that jumper plugs (P1~P9) are in the “A-B” (DTE) position. Reassemble the PDIUDS and mark “A-B” on the bottom label for future reference.
2. Connect the PDIU-DS to the appropriate digital telephone circuit per wiring diagrams in
Chapter 8 – DK40i/DK424 Universal Slot PCB Wiring and Chapter 9 – Station Apparatus.
3. Connect the appropriate RS-232 cable between the printer and the PDIU-DS (see Figures
10-27 and 10-30 for an example printer cable connection).
4. If Steps 2 and 3 are done properly, the Power and Ready LEDs on the PDIU-DS light when the
printer is turned on and ready.
5. Set the PDIU-DS DIP switch (SW1-1~4) for the application. See Figure 10-33 for DIP switch
locations.
Note

10-62

If using Toshiba computers and printers with X-ON/X-OFF flow control, set SW1-(4)
“ON” on the DIU connected to the computer and DIU connected to the printer.

PDIU-DS Programming
♦

♦

Program 20: Configures the PDIU-DS to connect to a serial printer (see Strata DK
Programming Manual for instructions and record sheets).
♦

LED 01: Should always be ON for PDIU-DS ports.

♦

LED 02: Should be OFF for PDIU-DS ports connected to printers.

♦

LED 03: Should be OFF for PDIU-DS ports that connect to DTE- or DCE-type printers.

♦

LED 04: Should always be ON for PDIU-DS ports.

♦

LED 05: Should be OFF for PDIU-DS ports connected to printers.

♦

LEDs 17~20: Data security groups can be used to enable or disable digital telephones
equipped with PDIU-DIs access to PDIU-DS ports connected to a printer. DIU stations
can only make data calls to DIUs in the same data security group.

Program 22: Configures PDIU-DSs to hunt if more than one PDIU-DS connected to the same
printer/server.

PDIU-DS to Modem Installation
Strata DK enables asynchronous-type (not synchronous) modems to be connected to PDIU-DSs.
This enables RPCI-DI or PDIU-DI equipped digital telephones that are connected to personal
computers, terminals, and other devices to share access to a modem or modem pool.
Important!

A modem(s) can be accessed internally for outgoing data calls or externally for incoming data
calls. Modems operate as DCE devices; so PDIU-DSs that are connected to them must be
configured to operate like a DTE device.
In the example shown in Figure 10-24 on Page 10-49, the line side of the two modems are
connected to RDSU/RSTS, RSTU2, PSTU, or PESU ports to establish a modem pool; however,
the line side of modems can be connected directly to a dedicated CO line.

Peripheral Installation

Modems must be “smart modems” that respond to AT commands and return result
codes. Modems are customer-supplied.

If modems are connected directly to telephone network CO lines, automatic transfer of CO line
voice calls to system modems (data call) do not function as described in the PC/Data Interface
User Guide.
For efficient operation and the best use of CO lines and modems, Toshiba recommends
configuring modems to RSTU2, PSTU or RDSU/RSTS standard station ports in a modem pool.
The RS-232 side of the modem connects to the PDIU-DS with standard RS-232 cables; the PDIUDS line side (RJ-11 connector) always connects to its own individual digital port.

Peripheral Installation
PC/Data Communications Interface Units

➤ To configure the PDIU-DS as a DTE device
1. Disassemble the PDIU-DS and place jumper plugs P1~P9 in the “B-C” position (MODEM).
2. Reassemble the PDIU-DS and mark “B-C” on the bottom identification label for future
reference. (See Figures 10-32 and 10-33.)
➤ To install modems to PDIU-DSs
1. Connect the PDIU-DS to the appropriate digital port circuit per the wiring diagrams in Chapter
8 – DK40i/DK424 Universal Slot PCB Wiring.
2. Connect the appropriate RS-232 cable between the modem and the PDIU-DS. Figure 10-29,
“PDIU-DS to Hayes-Type Smart Modem, RS-232 Connector/Cable Connections” shows an
example PDIU-DS to “smart modem” RS-232 connection.
Important!

All 10 PDIU-DS EIA leads (signals) should be connected to the modem. Consult the
modem’s documentation for correct RS-232 pin requirements; the requirements may
vary with each manufacturer.

3. Connect the line side of the modem to a RDSU/RSTS, RSTUS2, or PESU standard telephone
circuit or a dedicated CO line (consult the modem’s documentation to install it to a CO line).
Chapter 8 – DK40i/DK424 Universal Slot PCB Wiring provides station port wiring
information.
4. Set the PDIU-DS DIP switch (SW1-1~4) for the desired application. (See Figures 10-32 and
10-33.)
Note

If the modem tracks carrier detect (DCD, AT&C1), SW1(4) should be ON, and SW1(2)
should be OFF when PDIU-DS is connected to a modem.

5. Configure the PDIU-DS to connect to an asynchronous modem using Programs 20, 21, 22, 31
and 33.

♦

Program 21: For each PDIU-DS/modem pair, assign the digital, RSTU2, RDSU/RSTS, and
PESU ports that will be connected to the PDIU-DS and modem, respectively.

♦

Program 22/33: If more than one modem/PDIU-DS pair is configured as a system modem
pool, the PDIU-DSs should be set to hunt each other in Program 22. The modem RSTU,
PSTU, RDSU/RSTS, or PESU ports should be set to hunt each other in Program 33.

♦

Program 31: LED 18 should be turned ON for all RSTU2, RDSU/RSTS, or PESU station ports
that are connected to modems. This provides data security by preventing executive or privacy
override of modem calls.

Modem Setup Recommendations
1. Always make sure the escape sequence of the telephone PDIU-DI is default (+++).
2. Send AT command ATS2=43 to PDIU-DI.
3. Use a modified modem cable for the connection (see Figures 10-29 and 10-38) or reset the
PDIU-DS internal jumper plugs per the instructions in the DK Admin User Guide.
4. Send the following AT commands to the modem pool modem: ATS0=1, ATE0, ATQ0,
AT&C1, and AT&D2.

PDIU-DS Disassembly and Assembly
To set the jumper plugs (P1~P9) on the PCB inside the PDIU-DS for DCE or DTE operation, the
PDIU-DS must be disassembled.
➤ To disassemble the PDIU-DS

Auto Attendant
Auto Attendant operates like an automatic station attendant or switchboard operator that quickly
and efficiently distributes calls to stations selected by callers. Incoming calls are greeted by an
external announcement device that offers callers a menu of station locations associated with a
number, such as 3 for Sales, 4 for Customer Service, etc. Callers pick the destination just by
dialing the single number associated with it. The call is then transferred to the station. Callers can
also dial the intercom number directly.
This feature is available from three separate sources.

Peripheral Installation
Auto Attendant

Strata DK Built-In Auto Attendant (AA)
A built-in Auto Attendant feature is programmed into the Strata DK system software. To enable
the built-in AA to function, RRCS (-4, -8 or -12) DTMF tone receiver PCB (see Chapter 8 –
DK40i/DK424 Universal Slot PCB Wiring for RRCS and RKYS installation instructions).
The customer must provide digital announcement device(s), on which the greeting and menu that
the callers hear are recorded. The digital announcement devices must connect to Strata DK
standard telephone circuits. There is a series of programs (explained later) in the Strata DK
Programming Manual Record Sheets, which are for the built-in AA feature exclusively, not the
other two AA feature applications. Callers must use a DTMF (tone) telephone to select AA dialing
options.
The built-in AA feature offers flexibility in answering calls. Calls follow the basic sequences
described below and illustrated in Figure 10-41, “Built-in Auto Attendant Basic Call Sequences”.
Sequence A
The call is answered directly after being transferred from the Auto Attendant. The caller calls in on
CO lines assigned for built-in Auto Attendant, receives a greeting along with a menu of dialing
options, and then dials an option of the intercom number. The call is then transferred to a station,
which answers the call.
Sequence B
The call is not answered after being transferred from the Auto Attendant and is routed to an
optional secondary announcement, where it will receive a new announcement and the same or
additional dialing options. Some customers may not configure their AA system with a secondary
announcement; if so, their unanswered calls would follow sequence C or D.

The call is not answered after being transferred from the Auto Attendant and is routed to an
alternate station(s) assigned in system programming, ringing assignments.

Strata DK I&M

Peripheral Installation

Sequence C

10-77

Peripheral Installation
Auto Attendant

Sequence D
The call is not answered after being transferred from the Auto Attendant and is routed back to the
primary announcement. This is probably the least desirable of the four sequences, since the caller
hears a repeat of the announcement he just received seconds earlier.
Note

In all of the above sequences, the call can first ring telephones selected in system
programming for 12 or 24 seconds, and then be routed to the Auto Attendant if not
answered by any of the ringing stations. This is called Auto Attendant delayed ring.

Built-in Auto Attendant Programming
See Figures 10-41 and 10-42 for a comprehensive overview of built-in Auto Attendant (AA).

10-78

♦

Program 78 (61, 62, and 63): CO lines are assigned for built-in AA with this program. There is
no limit to the number of lines that can be assigned for AA, and each line can be set for any or
all of the ringing modes (DAY, DAY2, and NIGHT). See Programs 81~89 record sheet notes
in the Strata DK Programming Manual.

♦

Programs 81~89: Assign stations to ring if AA callers do not dial or AA calls are not
answered. Also, if not answered by a station set to ring during Immediate Ringing (or delay 2
ring), incoming calls can be set to ring built-in AA announcement ports on a Delayed Ringing
basis.

Strata DK I&M

5/99

Peripheral Installation
Auto Attendant

♦

Program 03: An RRCS (-4, -8 or -12) must be installed on the DK40i or DK424 RCTU for the
system to interpret DTMF tones generated by the CO. Use this program to tell the system that
the common control unit is equipped with an RRCS.

Important!

RKYS must also be installed on RCTU, RKYS does not need a Program 03 (or any
other) program assignment.

Program 25-1: If there are no RRCS circuits or announcement devices available for an
incoming CO line built-in AA call, the call will transfer to alternative station(s) (Programs
81~89) after a time duration assigned with this program.

♦

Program 23: As many as four digital announcement devices for primary announcements, each
requiring one standard telephone station port (Figure 10-42), can be assigned. Callers receive
primary announcements (60 secs. maximum announcement time) – which consist of the
greeting along with the delivery of menu prompts – when they first call (they may also be
rerouted back to the announcement after reaching a busy or ring no answer station).

♦

Program 24: Transferred calls that are unanswered at stations can be routed to a secondary
announcement device (60 secs. maximum announcement time), which typically first informs
the caller that the option they dialed was unavailable and then presents them with either the
same options offered by the primary announcement device or some additional ones (Figure
10-42).

♦

Program 09: Tells the system where to transfer built-in AA calls after the caller has dialed in
response to the delivered menu options.

♦

Program 60-6: Enter a DISA security code to prevent users from making unauthorized
external calls via the AA DISA access (Dial *) feature.

♦

Program 26: There will be times when transferred AA calls are not answered after camping-on
to a busy station. This program tells the system when to end the camp-on and to route the call
to another destination (it could be a secondary announcement device or alternative stations per
program 10-3, LED 18). If a station has Call Forward set, the call forwards to the proper
destination instead of routing per AA Program 10-3, LED 18.

♦

Program 10-3:

Strata DK I&M

♦

LED 18: Some customers may choose to configure their AA without a secondary
announcement device. In these arrangements, transferred calls that are unanswered can be
routed for normal ringing to some alternative stations set in Programs 81, 84, and 87, or
back to the primary announcement device. LED 18 should be ON if the calls should be
routed to stations assigned in Programs 81, 84, and 87. It should be OFF for the primary or
secondary announcement device option. If LED 18 is selected, see LEDs 16 and 17 for
disconnect timing options.

♦

LED 15: If LED15 is ON (and Music-on-Hold (MOH) is installed) the DK sends MOH to
callers when the AA routes a call to ring or camp-on a station. If LED 15 is OFF the DK
send ring-back-tone to the caller.

♦

LEDs 16 and 17: Set LEDs 16 and 17 to tell the system when to disconnect, as a
safeguard, built-in AA calls that have not been answered by stations. This feature assures
that the loop start CO line that the call was made on is free for other calls if the caller
hangs up before the call is answered. The initialized disconnect setting is 40 seconds. The
other timing options available are 150 secs. and 350 secs. Set LEDs 16 and 17 for the
desired time as follows:

5/99

Peripheral Installation

♦

10-79

Peripheral Installation

40 seconds: LED 16 = OFF. LED 17 = OFF.
150 seconds: LED 16 = OFF. LED 17 = ON.
350 seconds: LED 16 = ON. LED 17 = OFF.
Ground start lines disconnect automatically with this timer.
♦

Program 15: Selects Automatic Release (AR) on Voice Mail, AA or voice calls. This will
provide automatic release (if the calling party disconnects) without waiting for the safeguard
timer in Program 10-3.

Built-in Auto Attendant Installation
The built-in Auto Attendant feature only requires the installation of a feature key and customersupplied announcement devices to deliver announcements to callers. The feature does not require
the installation of any other devices.
➤ To install the customer-supplied digital announcement devices

Non-built-in Auto Attendant
Alternatives to using the Strata DK built-in AA feature, are voice mail systems, such as Toshiba
Stratagy or VP, with an AA feature and non-voice mail AA as a stand-alone device.
Non-built-in Auto Attendant Programming
The Auto Attendant programs described in “Built-in Auto Attendant Basic Call Sequences” on
Page 10-78 do not apply to the Non-integrated AA feature sources, but Strata DK Programs 03, 04,
10-1, 13, 16, 31, 33, 36, 37, 39, and 81~89 should be considered for proper operation.
Non-built-in Auto Attendant Installation
Non-integrated AA sources, such as voice mail devices and stand-alone units, connect to standard
telephone circuits (ports). See Chapter 8 – DK40i/DK424 Universal Slot PCB Wiring for more
information.

Multiple PIOU, PIOUS, RSSU Installation
Up to three PIOU, PIOUS, or RSSU PCBs can be installed in a system to simultaneously provide:
maintenance terminal (or modem) interface, Management Information System (MIS) for ACD
interface, and RS-232 voice mail interface (Toshiba proprietary or SMDI).
Each of these interfaces are provided by the modular jacks on a separate PIOU, PIOUS, RSSU
(Figure 10-37). Interface assignments are made in Program 03 (Code 41, 42, and 43). PIOU and
PIOUS Paging, SMDR, relay control, alarm sensor, and door lock functions will be active only on
the PIOU or PIOUS PCB which is assigned the lowest Program 03 code (41, 42, or 43). RSSU
only provides the TTY interface for SMDI, local maintenance, or ACD MIS but not for SMDR,
built-in maintenance modem or system OA.
If TSIU or RSIU/RSIS is installed, functions enabled in Program 76 will operate as programmed
and the same functions programmed in Program 03 (Code 41, 42, and 43) will not operate. For
more details regarding RSIU/RSIS/RMDS and TSIU installation, see RSIU installation in Chapter

Enhanced 911 Service (E911)

Enhanced 911 Service (E911)
The Toshiba Strata DK forwards 911 and 9+911 calls to designated ports to interface with external
third party adjunct translation equipment designed to handle them. The Strata DK provides up to
two QSTU2, KSTU2 or RSTU2 ports (standard telephone ports) to receive these calls and send
them to the third party E911 adjunct equipment along with the specific directory number of the
emergency calling station.
The Strata DK sends the telephone DN to the telephone company’s 911 tandem switch that
forwards the call to the proper Public Safety Answering Position (PSAP) where it is matched up
with a central Automatic Location Information (ALl) database to provide enhanced information to
the PSAP dispatcher.
Interface between the third party adjunct equipment and the E911 tandem CO must be via special
Centralized Automatic Message Accounting (CAMA) trunks. (Ordering of these specialized
trunks is done through a special ordering desk with your local phone company.)
Important!
●

●

DID numbers: In many cases, a DID service is the only way to provide a unique number
(CESID) for each station that is recognizable by the telephone company.
In order for this feature to be effective, 911 and 9+911 calls must be dialed from a DKT [DN]
or single-line telephone. 911 calls originating from a [PhDN] CO Line or Pooled Line button
bypass the adjunct equipment and go directly to the CO exactly as dialed.

E911 System Installation
1. Ensure that the QSTU2, KSTU2, RSTU2, RDSU/RSTS or PESU PCB is installed in the
system per Chapter 7 – DK40i/DK424 Universal Slot PCBs or each DK14 and DK40i
installation section.
2. Connect the E911 system to the selected QSTU2, KSTU2, RSTU2, RDSU/RSTS, or PESU
standard telephone port. (See Chapter 1 – DK14 Installation, Chapter 3 – DK40i Installation,
Chapter 8 – DK40i/DK424 Universal Slot PCB Wiring for wiring/interconnecting details.)
3. Program the Strata DK system for the required E911 features. (See “E911 Programming”.)
4. Install E911 external system per the manuals supplied by the vendor selected and used for the
interface.

E911 Programming
Program *10: Selections 11 and 12 assign the RSTU port to be used for E911 Service. Selections
91 and 92 assign an inter-digit timer for valid dialing and a delay timer before the station number
is sent to external E911 equipment.
➤ Remove the [DN] assignment for ports assigned to E911 so that someone calling a station
number will not accidentally call 911.

ACD Installation Guidelines

Digital announcement devices can be connected to DK standard telephone ports only; music
sources such as digital Music-on-Hold (MOH) devices, radio tuners, CD players, etc., can be
connected to standard telephone ports, electronic (not digital) telephone ports, or to the RCTU
MOH jack. The wiring diagrams for connecting announcement/music devices are:
♦

Digital announcers and/or music sources to standard telephone PCB ports: RSTU,
RSTU2, PSTU, PSTU2, RDSU/RSTS, PESU – see Chapter 7 – Wiring Diagrams. Digital
announcement devices and music sources can be assigned to any standard telephone port; they
are not restricted to designated Background Music (BGM) source ports (see Program 14-3 for
assignments). Announcement devices are designed to connect directly to standard telephone
ports. Do not use an isolation transformer to connect digital announcers.

Important!

Most music sources (600 or 8 OHM) are not designed to be connected to telephone
line circuits like the Strata DK standard telephone circuits. When connecting these
devices to standard telephone circuits, an isolation transformer may be required
between the music source and the standard telephone circuit. Figure 10-4 shows
how to connect an isolation transformer.

♦

Music sources to electronic telephone PCB ports: PEKU, PESU – see Chapter 8 – Wiring.
Music sources can be assigned to any PEKU or PESU port; they are not restricted to
designated BGM ports (see Program 14-3 for assignments).

♦

Music source to DK MOH input: The MOH source connected to the RCTU MOH jack can
be sent to ACD Groups selectively via Program 14-3.

➤ To connect a music source to the RCTU MOH jack
➤ See Chapter 10 – Peripheral Installation, “Music-on-Hold (MOH)/ Background Music (BGM)
Options” on Page 10-3.

ACD Installation Guidelines
The following steps show how to install the Strata DK ACD feature.

Step 1: Initialize the System
If installing a new RCTUBA/BB, RCTUC/D2, RCTUC3/D3, RCTUE3/F3 (ACD is not provided
with RCTUA3) processor PCB or if changing ROMs on the RCTU, the RCTU must be fully
initialized by running Programs 91-9 and 03 per the programming procedures in the Strata DK
Programming Manual.
If the system has been previously initialized and installed, it is not necessary to re-initialize the
RCTU when installing the ACD feature unless the RCTU ROMs or flash memory are changed to
install ACD. If changing ROMs, DK Admin or DK Backup software is recommended for
downloading/uploading previously programmed customer data.

11-4

Strata DK I&M

5/99

DK424 ACD Installation
ACD Installation Guidelines

Step 2: Install the RKYS Feature Key
➤ To install the RKYS2 (ACD/Auto Attendant) or RKYS3 onto the RCTU PCB
➤ Read the section titled “RKYS Feature Key Upgrades” on Page 5-48 and refer to Figure 5-30
for installation instructions.
Important!

It is not necessary to run any special programs (i.e., Program 03) when RKYS is
installed. RKYS can be installed before or after system initialization, and, before or
after the customer database is entered. The feature(s) provided by the RKYS are
enabled immediately when RKYS is installed. However, configuration programs for
Auto Attendant and ACD must be entered for the feature to operate.

Step 3: Install Related PCBs
1. Install PIOU, PIOUS, or RSSU PCBs in the highest numbered slots in any cabinets.
2. Install the RSIU PCB in slot 11 of the Base Cabinet only.

Step 4: Connect COM Port Wires
➤ Connect Strata DK to the SMIS PC per Figure 11-2.
SMDR, Page Outputs, Relay Controls, Alarm Sensor, and other miscellaneous options on the
PIOU or PIOUS PCBs will be active on the installed PIOU/PIOUS that is programmed with the
lowest Program 03 code (41, 42, or 43). The RSSU PCB only supports TTY, SMIS, or SMDI.

Step 5: Install ACD/SMIS Interface
If installing a SMIS personal computer, a RSSU, PIOU, PIOUS, RSIU or RSIS must be installed
(see Figure 11-2 for MIS RS-232 port installation).

Step 6: Set the MIS Channel
If there are more than 1,000 Agent calls in a heavy-traffic hour, the MIS channel must be set higher
than 1200 bps. The next higher speed, 2400 bps, can handle up to 1,300 calls per hour. Strata DK
allows 1200, 2400, 4800 or 9600 bps for the MIS channel.

SMIS registers ACD and PBX calls:
♦

An ACD call is a call that is sent (directly or transferred) to the ACD group.

♦

A PBX call is a call that is sent to the Agent’s$&'&DOO button [PhDN] or a call originated
from an Agent’s $&'&DOO button [PhDN].

Based on a total system speed of 10,800 bps (9600 + 1200) for auxiliary serial channels and a
requirement of one channel each for SMDI, TTY, SMDR, and MIS, the installation should use the
lowest MIS channel speed for the expected amount of traffic.
CAUTION!

Strata DK I&M

5/99

DK424 ACD Installation

Agent calls are defined as ACD incoming, PBX incoming/outgoing, and external/internal calls to
and from the Agent’s [PhDN].

If the channel speed is not set high enough, the MIS buffer may overflow,
causing loss of data to MIS.

11-5

DK424 ACD Installation
ACD Installation Guidelines

Step 7: Connect Announcement Devices
Connect the digital announcement devices that are used for each ACD Group (queue) to the
appropriate station ports. Digital announcers can be connected to any RSTU, RSTU2, RDSU/
RSTS, PSTU, or PESU standard telephone ports.
See Chapter 8 – Wiring Diagrams for MDF wiring to appropriate standard telephone ports.
♦

Use Program 14-3, Code 1, 2, and 3 to assign digital announcers to standard telephone ports.
Use Program 14-3, Code 5 and Program 14-5XX to configure the queue announcement pattern
for each ACD Group.

Step 8: Connect Music Sources
Connect the music source for each ACD Group (queue) to the appropriate station port or to the
RCTU MOH jack. Music sources can be connected to RSTU, RSTU2, RDSU/RSTS, PSTU,
PEKU, or PESU station ports or to the RCTU MOH jack. See Figures 10-3, 10-4, 10-5 and
“Alternate BGM Source Installation” on Page 10-9.
See Chapter 8 – Wiring Diagrams for wiring information.
Important!

If connecting a music source to RSTU, RSTU2, RDSU/RSTS, PSTU, PEKU, or
PESU standard telephone ports, an isolation transformer may be required as shown
in Figure 10-4 to protect the music source from excessive current/voltage.

Each ACD Group can have a separate music source or Groups can share music sources in any
combination.
Music source port assignments are made in Program 14-3, Code 4. Music source timers are set in
Program 11-5 (1, 2, and 3).

Step 9: Install ACD to Strata DK Built-in Auto Attendant (AA) Integration
If ACD calls route to an ACD Group via the Strata DK built-in AA, install and program the AA
per “Built-in Auto Attendant Basic Call Sequences” on Page 10-78 of Chapter 10 – Peripheral
Installation.
Auto Attendant “single digits” are assigned to ACD Groups in Program 09.

Step 10: Assign ACD to Toshiba Stratagy or VP AA Integration
If a Toshiba Stratagy or VP AA must answer calls and transfer CO lines to ACD Groups, assign
the CO lines to ring the Strata DK standard telephone ports connected to the Stratagy or VP AA in
Programs 81~89.
Also program the appropriate Strata DK station ports to interface with the Stratagy or VP ports in
Program 31.
Program the Stratagy or VP AA to hookflash and dial ;; to transfer calls to ACD Groups
(where XX = the ACD Group Number: 01~16).

ACD Line Operation/Programming Considerations

ACD Line Operation/Programming Considerations
ACD Programming
All types of DK lines can be routed to ACD Groups (ground/loop start, DID/Tie/DNIS/ANI).
Lines can be assigned in programming to route directly to ACD Groups when they ring or dial into
the Strata DK system. All line types can be programmed to transfer into an ACD Group from any
telephone, attendant console, or built-in or external AA.
Use the ACD programming guidelines and flowcharts provided in Chapter 6 of the Strata DK
Programming Manual to configure the remaining ACD items per the customer’s requirements.
The following paragraphs describe differences in the operation and programming of ground/loop
start lines versus DID/Tie/DNIS/ANI lines used with an ACD system.

Direct Incoming Assignments to ACD Groups
Ground/Loop Start Incoming Line Calls
Program 14-0: Used to make the line assignments to send calls directly to specific ACD Groups. If
a ground or loop start line is assigned to an ACD Group in Program 14-0, it routes per that ACD
Group’s call routing assignments.
ACD calls ring on Agent $&'&DOO [PhDN] buttons. Do not assign CO /LQH or 3RROHG/LQH
*US buttons to Agent telephones. ACD CO /LQH or 3RROHG/LQH*US buttons can be assigned
to overflow destination telephones.
Note

Program 14-0 has priority over all other ringing assignments except Program 78 (61, 62,
and 63). If a line is assigned to ring an ACD Group in Program 14-0 at the same time the
line is assigned to ring the DK built-in AA in Program 78, the line routes to the AA.

DID/Tie/DNIS/ANI Incoming Line Calls
Program *09 or Program 71-1, 2, or 3: assigns DID/Tie/DNIS/ANI incoming digits to ACD
Groups and DID digits to ring designated station ports. ANI only lines must route to the same
ACD Group (see Program 71-1, 2, or 3 address 349 or 499).

If the incoming digits (XXXX) dialed from a Tie or DID line match the digits assigned to an ACD
Group, the call routes per that ACD Group’s call routing assignments.
ACD calls ring on Agent $&'&DOO [PhDN] buttons. Do not assign DID/Tie/DNIS/ANI /LQH
buttons to Agent telephones. However, ACD DID/Tie/DNIS/ANI /LQH buttons can be assigned to
overflow destination telephones.

Transfer From Built-in Auto Attendant (AA) to ACD Group

DK424 ACD Installation

Program 04 or Program 71-1: assigns Tie line digits to ring at designated station ports (see
Program 17, LED 05).

Ground/Loop Start Line Calls
Calls can be assigned to ring into the DK built-in AA in Program 78. Each ACD Group can be
assigned a unique one or two-digit AA dialing prompt in Program 09. Incoming calls on these
lines are answered by the AA. The caller then enters the one or two-digit number and is connected
to a specific ACD Group.

Strata DK I&M

5/99

11-7

DK424 ACD Installation
ACD Line Operation/Programming Considerations

DID/Tie/DNIS/ANI ACD Line Calls
Calls cannot be assigned to ring the DK built-in AA, so they cannot be transferred from the DK
AA to an ACD Group.

Transfer From External AA to an ACD Group
The external AA (Stratagy or VP) can be programmed to transfer calls to specific ACD Groups by
assigning one-digit dialing prompts to each Group.
To transfer a call into an ACD Group from an external AA, the user must hookflash and dial
;; (;; = ACD Group number 01~16).
Ground/Loop Start Line Calls
Calls can be assigned to ring external AA ports in Program 81~89. The external AA can be
programmed to transfer calls to particular ACD Groups by assigning one-digit dialing prompts to
each Group.
DID/Tie/DNIS/ANI Line Calls
Calls can be assigned to ring directly into an external AA by assigning incoming digits to the AA
ports in Programs *09 or 71 for DID/DNIS/ANI lines and Programs 04 or 71 for Tie lines (see
Program 17, LED 05). Internal station to station [DN] calls cannot be transferred to ACD Groups.

Overflow From an ACD Group Queue
ACD Calls
ACD calls can be routed to overflow to a [PDN], [SDN], [PhDN], to normal CO line ringing
assignments, to another ACD Group, or to a Distributed Hunt [DH] Group (see Strata DK
Programming Manual, Flowcharts 6-3~6-10).
If the overflow [PhDN] or [PDN] is idle when overflow time occurs, an ACD call rings the
overflow destination [DN]. If it is busy, the ACD call does not overflow but remains in the ACD
queue until the overflow destination, an Agent telephone in the ACD Group, or a DH Group
member telephone becomes idle. The first device (Agent telephone or overflow destination) to
become idle receives the call. In this case, DID/Tie/DNIS/ANI lines operate the same as ground,
and loop start lines.
Ground/Loop Start Lines
Lines can overflow from an ACD queue to the DK CO line Normal Ringing assignments set in
Programs 81, 84, 87 and *81, *84, and *87; to the DK built-in AA or to an attendant console.
When the overflow time or point occurs, calls immediately exit the ACD Group queue and ring all
stations assigned to ring in Programs 81, 84, or 87 and *81, *84, and *87 (no delay ringing
assignment operates during overflow). Idle stations and [DNs] ring normally while busy stations
and [DNs] have a muted ring.
Auto Attendant
If the overflow destination is the DK built-in AA, calls overflow immediately when overflow time
occurs and are routed per the AA program assignments. If the AA is busy, the call still exits the
ACD queue and queues onto the AA announcement port.
Attendant Console
If the overflow destination is the attendant console, calls immediately exit the queue and alert the
console whether the console is idle or busy. This applies to overflow queue time out (Programs 111 and 14-4) and overflow point (see Programs 14-3, 14-5, and Flowcharts 6-8~6-10).

11-8

Strata DK I&M

5/99

DK424 ACD Installation
ACD Line Operation/Programming Considerations

DID/Tie/DNIS/ANI Lines
Lines cannot overflow to the DK CO line Normal Ringing assignments set in Programs 81, 84, 87
and *81, *84, and *87, or to the DK built-in AA.
If the overflow destination is assigned as either the DK CO line normal ringing or built-in AA,
DID/Tie/DNIS/ANI lines route to the substitute destination [DN] assigned in Program *14-2. This
applies to overflow queue time out and overflow point destinations assigned in Programs 14-4/111, and 14-5, respectively.
If the overflow destination [DN] is busy when overflow time occurs, the ACD call does not
overflow but remains in the ACD queue until the overflow destination [DN] or an Agent telephone
in the ACD Group becomes idle. The first device (Agent telephone or overflow destination) to
become idle receives the call.

ACD Group Status
After Shift Mode
When an ACD Group is placed in the After Shift mode, calls are not sent to the ACD Group’s
queue or Agents, but are routed to the After Shift destination set in Program 14-6. The After Shift
operation for each possible case is described below (also see Strata DK Programming Manual,
Flowchart 6-5):
If the After Shift destination is idle, all line types ring the idle destination. DID/Tie/DNIS/ANI
and ground/loop start lines operate the same.

♦

If the After Shift destination of an ACD Group is another ACD Group, and all Agents in the
destination Group are busy on calls or in the After Call Work Time mode, the call is placed at
the end of the destination ACD Group’s queue. If there are no Agents logged in for the After
Shift Group, the call is sent to that Group’s After Shift destination. DID/Tie/DNIS/ANI and
ground/loop start lines operate the same.

♦

If the After Shift destination is a [DN], the [DN] rings. If the station is busy, DID/Tie/DNIS/
ANI lines camp on to the [DN] while ground/loop start lines busy override ring the port.

♦

If the After Shift destination is the DK Normal Ringing assignment, ground/loop start lines
ring stations assigned to the ACD lines in Programs 81~89 (including delayed ringing
assignments). DID/Tie/DNIS/ANI lines do not ring stations in the Normal Ring assignments
but ring or camp on to the [DN] assigned in Program *14-2.

♦

If the After Shift destination is the DK AA, ground/loop start lines are answered by the AA
and routed after the caller dials a digit prompted by the AA. DID/Tie/DNIS/ANI lines do not
route to the AA, but ring or camp on to the [DN] assigned in Program *14-2.

♦

If the After Shift destination is the attendant console, calls ring or queue onto the console
whether it is busy or idle. This applies to DID/Tie/DNIS/ANI and ground/loop start lines.

All Agents Unavailable Mode
If all the Agents in an ACD Group become unavailable simultaneously, calls that would normally
ring into the ACD Group or enter the Group’s queue are routed to either the Group’s After Shift
destination, set in Program 14-6 or to the Group’s Overflow Point destination, set in Program 14-5
(see Strata DK Programming Manual, Flowchart 6-6).

DK424 ACD Installation

♦

The option of where to send calls when all Agents are unavailable is set system-wide for all ACD
Groups in Program 10-4, LED 04. All line types (ground/loop start and DID/Tie/DNIS/ANI)
follow this operation. If the “All Agents Unavailable Operation” is set to route calls to the After
Shift destination set in Program 14-6, (Program 10-4, LED 04 “Off”), calls to a Group whose
Agents are all unavailable are treated as if the ACD Group were in the After Shift mode.

Strata DK I&M

5/99

11-9

DK424 ACD Installation
ACD Line Operation/Programming Considerations

If the “All Agents Unavailable Operation” is set to route calls to the Overflow Point destination set
in Program 14-5 (Program 10-4, LED 04 “On”), calls to a Group whose Agents are all unavailable
are treated as if they overflowed from the Group’s queue even if the overflow destination is busy.
If the “All Agents Unavailable” overflow destination is another ACD Group, calls route to an idle
Agent, or are placed at the end of the overflow ACD Group’s queue.

Agent Ring No Answer Call Treatment
If an ACD call rings an Agent telephone for the time specified in Program 11-2 and the call is not
answered, the call is routed to ring another idle Agent in the same ACD Group for that same time
duration (see Strata DK Programming Manual, Flowchart 6-7).
This continues until all idle Agents in that Group have been rung. If the call is not answered by an
Agent, the call then routes to the destination assigned in Program 14-5. Two consecutive Ring No
Answer (RNA) calls to the same Agent automatically places that Agent’s telephone in the
Unavailable mode. The RNA operation for possible cases is described below:
♦

If the RNA destination is an idle [DN], it rings when RNA occurs. If the RNA [DN] is busy
when RNA occurs, DID/Tie/DNIS/ANI calls camp on to the [DN] and ground/loop start lines
route to the Normal Ringing assignments in Programs 81~89 and *81, *84, and *87 (including
delay ring assignments).

♦

If the RNA destination is an ACD Group, the call rings an idle Agent in that Group when RNA
occurs. If all Agents in the RNA destination ACD Group are busy when RNA occurs, DID/
Tie/DNIS/ANI lines route to the destination assigned in Program *14-2 and ground/loop start
lines route to the Normal Ringing assignments in Programs 81~89 and *81, *84, and *87
(including delay ringing assignments).

♦

If the RNA destination is the DK Normal Ringing assignment, DID/Tie/DNIS/ANI lines route
to the [DN] assigned in Program *14-2 and ground/loop start lines route to the Normal
Ringing assignments in Programs 81~89 and *81, *84, and *87 (including delay ring
assignments). If the RNA destination is busy when RNA occurs, DID/Tie/DNIS/ANI lines
camp on to the [DN] assigned in Program *14-2 and ground/loop start lines mute ring the busy
[DN].

♦

If the RNA destination is the DK built-in AA, DID/Tie/DNIS/ANI lines route to the [DN]
assigned in Program *14-2 and ground/loop start lines route per the AA program assignments.
If the AA is busy when RNA occurs, DID/Tie/DNIS/ANI lines camp on to the [DN] assigned
in Program *14-2 and ground/loop start lines queue onto the AA announcement port.

♦

If the RNA destination is the DK attendant console, RNA calls ring or queue on the console
whether it is busy or idle. This applies to ground, loop, Tie, DID, DNIS, and ANI lines.

ACD SMDR Printout Examples
Auto Attendant, DNIS, ANI, DID, and Tie line ACD calls can be identified on SMDR printouts.
Several SMDR printout examples noting ACD information are provided. (See Figures 11-3
through 11-10). However, Toshiba recommends using SMIS to track ACD call data rather than
SMDR. SMIS is designed to track ACD/PBX agent calls.
Loop and ground start line ACD calls can only be identified by line and station numbers. The ACD
tag is not applied. For detailed ACD call record reporting, Toshiba recommends using SMIS.
The Work Unit (or Stroke) count data, which is entered from the Agent telephone while on an
ACD call, is printed in the account code field of the SMDR output data (last 15 columns).
Note

11-10

If multiple Work Unit entries are entered on the same ACD call, SMDR only sends data
for the last entry. MIS or SMIS receives all entries made.

Insight DK (DK424 only)
The Insight DK™ and Insight DK Plus are full-featured ACD MIS tools for call center
supervisors, providing user-defined supervisor displays, user-defined historical reports, electronic
wall board connections, and inView LAN-based status display messaging. Insight DK and DK
Plus are Windows-based MIS software programs that work with PCs running Microsoft®
Windows® 95 (Vers. 4.00.950A, B, or C), Windows 98 or Windows NT® with Service Pack 3.
For more information, refer to the Strata DK424 Call Center Solutions General Description or
other Insight DK documents listed in “Related Documents/Media” on Page xviii of the
Introduction.

Call Center Viewer (CCV)
Call Center Viewer™ is a software application designed for ACD supervisors which enables them
to view the calling states and activities of ACD Groups and Agents. With the Call Center Viewer,
supervisors can customize the ACD displays, set Call Waiting alarms, and send messages to Wall
Boards. The software works on a PC running Windows 95.
This section discusses various combinations of connections between the Strata DK System and the
Call Center Viewer PC(s). The Call Center Viewer application can be configured to work directly
with the Strata DK, or with a SMIS PC, and/or with one Master PC plus additional PCs also
running Call Center Viewer application programs.

Application Overview
Call Center Viewer organizes and displays events reported by the Strata DK MIS port. This
application enables you to see the following:

Strata DK Requirements
The RKYS3 must be installed on the Strata DK RCTU processor card in order for the Call Center
Viewer to work.

Host PC Requirements
The host PC does not have to be dedicated to the application, since the Call Center Viewer
application was designed for multi-tasking.
When the Call Center Viewer application connects to the Strata DK system, it functions as a
machine-to-machine interface, constantly updating call center data. The Call Center Viewer
application should be installed on a PC with the following minimum requirements:
♦

Windows 95

♦

IBM®-compatible 100MHz Pentium® class processor

♦

16MB of RAM

♦

Hard drive with 10MB of available space

♦

One available serial communication ports; two if Wall Boards are used

♦

SVGA color display

♦

Windows Graphics Acceleration card

♦

Keyboard and Mouse

♦

Parallel Printer Port

Increasing the PC’s processor speed and adding RAM will improve the host PC’s performance,
therefore boosting the performance of the Call Center Viewer application.
To ensure data integrity, Toshiba strongly recommends that both the host PC and CCV application
remain in continuous operation once the CCV application session begins.

Note

Strata DK I&M

The term “Wall Board” refers specifically to the physical Wall Board. The Call Center
Viewer software uses the term “Reader Board” in place of “Wall Board.”

CCV Configuration
Considerations
The Call Center Viewer application can connect solely to the Strata DK280 or DK424 port, or in
parallel with other CCV applications, or with a Software MIS (SMIS) computer. The number of
CCV PCs and the hardware configuration determines the type of connectors needed.
Depending on the configuration of the RS-232 port of the Strata DK System, a null modem adapter
may be needed.

Connectors
This section describes the various connectors used with the CCV. Specific instructions for different
types of configurations appear later in this section.

CCV Configuration Instructions

Connecting CCV and SMIS
Call Center Viewer monitors the data flowing between the Toshiba SMIS and the Strata DK. This
enables the CCV application PC to display information and work in conjunction with a SMIS
computer that is connected to the same Strata DK280 or DK424 MIS port.
The CCV application and the SMIS application must reside on separate computers because SMIS
requires a dedicated PC. The CCV provides the real-time status displays and connection of
electronic Wall Boards. SMIS is used to provide historical ACD reports. The CCV can run
concurrently with other Windows applications on other ACD Supervisors’ PCs.
➤ To connect the CCV to SMIS PC, less than 50 feet from the DK
1. Install the CCVY connector into the Strata DK MIS port (RSIU, RSIS, RMDS, or PIOU
PCBs). See Figure 11-19.
Depending on the configuration of the RS-232 port of the Strata DK System, a null modem
adapter may be needed
2. Use a six-conductor modular telephone cord to connect the DK MIS port to the “DK MIS”
port on the CCVY.
3. Plug a six-conductor modular cord into the “MASTER” port of the CCVY. Use a PPTC-9 or
PPTC-25F at the other end of the cord to connect to the SMIS or Main Call Center Viewer PC.
4. To connect up to two more PCs, use a six-conductor modular telephone cord between the
CCVY “MNTR1” or “MNTR2” port(s) with a PPTC-9 or PPTC-25F to attach the PCs.

Spectrum Electronic Wall Boards
Electronic Wall Boards can be connected to each supervisor’s PC to display call center status data
over head from the Call Center Viewer application. This provides visibility of important call center
event information to both supervisors and agents. The supervisor can also send custom, user
defined, text information to the electronic Wall Board. This can be used for general information,
motivational messages, etc.
One copy of the Call Center Viewer application supports a Wall Board network which can cover
all active ACD groups. The Call Center Viewer application works with Spectrum 200, 300 and 700
series electronic Wall Boards listed below. In the following table, “R” stands for a red display and
“C” stands for a three-color display: green, amber, and red.

Fault Finding

12

This chapter describes the procedures to diagnose faults in the Strata DK14 and DK40i Key
Service Unit (KSU) and the DK424 system. Faults are classified and then cleared by replacing the
malfunctioning unit and by performing operational tests in the sequences by prescribed by the fault
clearing flowcharts in “Fault Isolation Flowcharts” on Page 12-10.

Fault Classification
A Fault Classification Flowchart is provided to ensure that fault clearing is pursued in a logical
sequence (Flowchart 12-1 on Page 10).
The flowcharts assume that the fault was discovered and reported by a digital or electronic
telephone user. All faults, therefore, are classified according to the way they would appear at the
digital or electronic telephone.

Fault Clearing Procedures
Before attempting to clear any fault, ensure that it is in the system and not caused by associated
external equipment, such as wiring, MOH source, etc.
Important!

Many system features are assigned, enabled or disabled using software entries as
described in the Strata DK Programming Manual. It is very important to verify that
the system programming is correct and functional before troubleshooting the
hardware.

Initialize the system (Programs 91-9 and 03) before testing new systems or when changing the
DK14 or DK40i KSU, or DK424 RCTU PCB.

CAUTION!

When handling PCBs, do not:
Drop a PCB.
Stack one PCB on top of another.
Handle a PCB without discharging any static electricity from your person by
touching the grounded cabinet.
Touch the PCB contacts with your fingers.

Important!

If the fault is not cleared by substituting a PCB, reinstall the original PCB in the
KSU/cabinet before trying another PCB.

Parts Return
1. Pack the part in a suitable container (original box is highly recommended). Use anti-static
containers for all PCBs and feature cartridges. Use plastic bags for digital or electronic
telephones, KSU/cabinet, etc.
CAUTION!

To avoid damage, never write on the part itself.

2. Describe the nature of the defect on an information tag. Attach the tag to the front of the unit
with string (not wire) so the tag can remain attached during the testing and repair.

Fault Finding
KSU/RCTU Fault Isolation

KSU/RCTU Fault Isolation
The DK14 and DK40i KSU circuits, and DK424 RCTU circuits may contain a “soft” fault due to
an extremely high level of static electricity and/or improper or no System Initialization.
If the KSU or RCTU is found defective during the fault finding procedures, attempt to clear a
“soft” fault before returning the DK14 or DK40i KSU, or the DK424 RCTU PCB for repair.
➤ To clear a “soft” fault
1. Initialize the system, then re-program the system as necessary to test for the fault.
2. If the fault returns again, tag the defective KSU or RCTU and return it for repair.

Fault Isolation Procedure
1. Test the power supply (see “Testing the System’s Power Supply” on Page 3-6). Test AC power
and ground per system installation section.
2. Verify that the BATT jumper plug on the DK14 or DK40i Base KSU motherboard, or the
DK424 common control RCTU PCB, is in the ON position.
3. If there are feature keys, verify that they are correctly installed:
♦

DK14: verify that the QKYS is correctly installed per Chapter 1 – DK14 Installation.

♦

DK40i verify the KKYS option installation on the K4RCU3 per Chapter 3 – DK40i
Installation.

♦

DK424 verify correct installation of the RRCS or RKYS options on the RCTU per
Chapter 7 – DK40i/DK424 Universal Slot PCBs.

4. For the DK14 and DK40i, skip to Step 6.
For the DK424, make sure the system power is OFF. Then install an RCTU in the “RCTU”
slot of the base cabinet. If RCTUD is installed, install RCTUC in the “R11” slot of the base
cabinet. If RCTUBB is installed in the “RCTU” slot, install RCTUBA in the R11 slot of the
base cabinet.
5. For DK424: If installing RCTUBA and RCTUBB, RCTUC and RCTUD, or RCTUE and
RCTUF connect them together with the two ribbon cables supplied per Chapter 5 – DK424
Installation.
6. Verify that all PCBs are installed in proper slots per Chapter 1 – DK14 Installation, Chapter 2
– DK40i Configuration, or Chapter 4 – DK424 Configuration.
7. Turn system power ON; backup the customer database using DK Admin or DK Backup. For
the DK424, verify that the heartbeat LED flashes on RCTUA3, RCTUBB, RCTUB, RCTUD,
RCTUE (RCTUA, RCTUBA, RCTUC and RCTUF do not have heartbeat LEDs).
8. Run System Initialization Program 91-9 (two times) per Program 91-9.
9. Run Program 03, for all option PCBs installed per Program 03.
10. Run the processor RAM tests with Program 00 (Part 2).
12. After performing the above steps, tag the defective PCB(s), Power Supply, or KSU, and return
for repair.

DK424 RPSU280 Power Supply Test

DK424 RPSU280 Power Supply Test
This test applies to the base and expansion cabinet RPSU280 and RPSU424 power supplies.
Cabinet PCBs may or may not be installed when beginning this test. Some steps in the test require
an AC/DC voltmeter that can measure up to 50VDC and 150VAC.
Notes
●

●

RPSU280 and RPSU424 power supplies are fit, form, and functionally the same. They can be
interchanged and mixed in DK280 and DK424 systems.
To test DK14 or DK40i power supplies, see their respective installation in
Chapter 1 – DK14 Installation or Chapter 3 – DK40i Installation.

➤ To test the Power Supply
1. Verify that the correct RPSU280 and RPSU424 jumper plug is installed in the jumper plug
socket. The plug with the wire must be installed on the base cabinet power supply and the plug
without the wire must be installed on all expansion cabinet power supply. One of each plug is
supplied in a plastic bag attached to each power supply.
2. Verify the power supply ON/OFF switch is in the ON position.
Note

The base cabinet ON/OFF switch must be ON to allow expansion cabinet power supplies
to operate.

Verify that the data ribbon cable is plugged into the base from all expansion cabinets.
Check AC power and ground per AC Power and Grounding Requirements in
Chapter 5 – DK424 Installation.
3. Ensure the AC power cord is plugged into the RPSU280 or RPSU424 AC IN connector and
the commercial AC outlet (or power strip (RPSB) if used). The green power LED indicator
will be on when AC power is connected to the power supply and the ON/OFF switch is ON.
Take appropriate action to restore AC power if necessary.
Note

The green power LED indicates that AC voltage is present at the AC IN connector only
when the power supply ON/OFF switch ON. This is helpful for battery backup systems—
the POWER indicator will be OFF and the +5V and –5V indicators will be ON when the
DK280 or DK424 is operating on reserve power (batteries).

4. Verify that the +5V and –5V green LED indicators are ON. If one or both indicators are OFF,
remove cabinet PCBs one at a time and check if +5V or –5V indicators turn on (it may be
necessary to turn power OFF and ON to restore ±5V). Replace defective PCBs causing a ±5V
fault.
Important!

If a CRCU PCB is installed on an RCTU PCB, ±5V will turn OFF. Do not install
CRCU on RCTU. Only RRCS DTMF PCBs can be installed on RCTU.

5. Lightly press the three –24 circuit breakers to ensure they have not accidentally opened during
shipment. If a circuit breaker continues to “trip,” remove cabinet PCBs, one at a time, and try
to reset the circuit breaker. Replace defective PCBs if causing –24V fault. If breakers continue
to trip, go to Step 7.
6. Using a DC voltmeter, measure the power supply DC output voltages at the “DC OUT”
connector on the power supply. Place the positive (black) meter lead on the FG screw. Insert
the negative (red) meter lead tip into the DC out connector until it makes contact.

12-4

Fault Finding
DK424 RPSU280 Power Supply Test

Make sure that +5V, –5V, and –24V are within the range specified in Figure 12-2. Do this test
with PCBs inserted; if a voltage(s) is not within specification, remove PCBs, one at a time and
recheck the voltage. (Power may have to be turned OFF and ON to restore a voltage.)
Replace any PCB which causes a voltage fault. If voltage tests out of specification with all
PCBs removed from the cabinet, go to Step 7.
7. Unplug the cabinet DC power connector from the power supply “DC OUT” jack. Attempt to
reset -24V breakers per Step 5. If breaker cannot be reset replace power supply; if breakers
reset go to Step 8.
8. Check the power supply DC voltages measuring at the power supply “DC OUT” jack with the
black meter lead on the BATT “+” terminal. If the DC voltages are within specification when
the cabinet DC power connector is disconnected but not within specification when the cabinet
is connected, the cabinet is probably defective.
If the DC voltages are not within specification when the cabinet DC power connector is
unplugged, the power supply probably is defective. Replace the defective cabinet or power
supply per Chapter 5 – DK424 Installation.
Important!

+5VDC (white wire) cannot be checked with the DC out cable disconnected.

9. Using the DC voltmeter, check the RPSU280 battery charger as follows: Remove the battery
cable from the power supply “BATT” connector. Place the positive (black) meter lead on the
“+” BATT pin and the negative (red) meter lead on the “–” BATT pin. The allowed range is
(–26.3VDC ~ –27.8VDC). The “BATT” connector output of the RPSU424 is 0VDC unless
connected to good batteries. If BATT output is not within specification, replace the RPSU280.

Computer Telephony
Integration

Computer Telephony Integration

This chapter gives you information about Computer Telephony Integration (CTI). Currently, it
includes procedures for using a Personal Computer Interface Unit (RPCI-DI) for Telephony
Application Programming Interface (TAPI) running under both Microsoft® Windows® 95,
Windows 3.1 and Windows 3.11 for Workgroups.

About Strata DK and TAPI
The Telephony Specification was jointly developed and copyrighted by Intel® and Microsoft. It
consists of both TAPI, used by applications, and the Telephony Service Provider Interface (TSPI),
implemented by other service providers.
Toshiba provides the TAPI connection through a Strata DKT2000-series telephone with a
modified Data Interface Unit. The Personal Computer Interface Unit (RPCI-DI) for TAPI
integrates into the bottom base of a 2000-series telephone.
There are two separate modes of operation for the Toshiba TSPI depending on the type of Strata
DK telephone system that the DKT/RPCI-DI is connected to. Toshiba’s TSPI is configured using
the Telephony icon installed as part of TAPI in the Microsoft Windows Control Panel.
Windows Telephony is a component of Windows Open Services Architecture. This architecture
provides telephony services when connected to many different telephone switches. Therefore, an
application needs to know only the definition of the API (Application Program Interface) and not
its implementation.
The Strata DK TAPI Service Provider (DK TSPI) comes with each RPCI-DI. This device, along
with this software module, allows a Windows-based PC to interconnect with the phone system for
receiving and making calls. Any TAPI-compliant PC software becomes compatible with Strata DK
systems.
The disk set also contains a “middleware” software known as StrataLink. This application enables
other Windows-based software to also work with Strata DK systems.

Requirements
To use TAPI with the DKT Service Provider, you must have an IBM-compatible PC with 8 MB
RAM, running:
♦

Windows 95, Windows 3.1 or Windows for Workgroups 3.11.

♦

Microsoft TAPI installed. (Most TAPI applications automatically install TAPI as part of the
normal installation process.)

Using StrataLink for CTI Connections

Using StrataLink for CTI Connections
This section provides important general information on StrataLink and how it operates. For
specific instructions on using StrataLink with a given software application, see the Application
Notes for that software.
Many Windows-based Computer Telephony software products either do not have a TAPI
compliant version of their product, or need the additional capabilities of a “middleware” software
to use their software with the Strata DK.
StrataLink is a “middleware” application that provides the multiple line and translation functions
for non-TAPI software applications. StrataLink provides the flexibility to interface multiple
applications and to be able to define the actions desired for each button on the connected phone.
StrataLink works with Toshiba’s TAPI Service Provider (TSPI) v2.26 or higher. Both the TAPI
Service Provider and the StrataLink application are included on the TAPI installation disks. Either
TSPI, StrataLink, or both can be installed. The installation program selects the appropriate TAPI
Service Provider for the PC’s operating system.

StrataLink Operation
StrataLink communicates with software applications using Microsoft Windows Open System
Architecture capabilities for Dynamic Data Exchange (DDE). The specific messages are defined
as Actions in StrataLink. StrataLink contains a number of Actions for popular applications. The
user can select from this list or define new Actions for an application.
StrataLink also accepts DDE Execute commands. These commands enable dialing calls,
answering calls, holding calls, blind transfer of calls, and hanging up. Many of these commands
can be directed to specific telephone buttons or the TSPI can choose the button.
When using this interface for dialing, StrataLink also provides for button preferences to be used
for intercom, local, or long distance calls. It can include prefix digits prior to dialing the number
and automatically insert a “1,” if required for long distance calling.
Incoming calls are based upon events from the TAPI Service Provider. These events (Call Ringing,
Call Connected, Call Hold, Call Cleared) are used in the Triggering Rules that define what Actions
are needed and when. Filters can be used to qualify when an action should be taken.
Figure 13-1 shows how StrataLink is used with Windows applications to provide telephone
services with your desktop PC.

StrataLink has three basic functions. It:
Accepts events from the telephone, applies filtering rules and conditions, and causes actions to
take place in the application

♦

Provides for outbound calling and call control from the application

♦

Provides tools for testing the interface and debugging or monitoring the call events

Incoming Call Events

Computer Telephony
Integration

♦

Using Windows TAPI, StrataLink accepts the Strata DK commands and provides a selection of
Actions based upon call events (Triggers). Each Trigger can have one or more conditions applied
to control how, when, or if the Action should be performed. Each Action has a set of parameters
that can customize the application for the user. A list of Trigger events can be created for the
desired Action.
Provides Outbound Calling and Call Control
The Computer Telephony Software creates events for controlling the telephone. The events are
controlled using DDE exchanges originating from the application and received by StrataLink. In
some programs, the application software must be configured for this operation.
Tests, Debugs, and Monitors
StrataLink provides several important testing and debugging functions. These tools enable the
installer to verify whether the link is functional. The installer can also use the TAPI link to view
the details of the information being passed. These tools reduce the guesswork in the
troubleshooting and operation verification.
Starting StrataLink
The Main Screen for StrataLink is shown in Figure 13-2. This screen provides access to the main
menu, driver setup, the ability to enable/disable the TAPI link, and a testing interface with the
telephone. Most Setup items are located under Setup item from the Main Menu.

➤ To install and set up StrataLink
1. Load the software by inserting Disk 1 in the floppy disk drive, and from Windows, selecting
Run…, typing A:\Setup.exe and pressing Enter.
2. Follow the instructions for installation.
3. Start StrataLink, enable TAPI and wait for the green light that indicates a communication link
with the TAPI Service Provider was successful.
4. Press Driver Setup to configure the driver if not previously done as part of the installation.
5. The Driver Setup selects the COM port, system type, and key definitions for the connected
phone. Be sure to assign meaningful labels for the keys on the phone as these are used for
creating the Triggering Rules.
6. Test the link with the phone using the Test section. Select the button to place a call, enter a
number to dial and press Dial.
7. Once the link has been established with the phone, go to Setup to establish the Preferences,
add or edit any new Actions.
Note

Actions can be tested using the Add/Edit Action and Show Test Params button.

8. Create Trigger Rules using the events expected from the phone and the desired Action.
9. Make several test calls to verify all the pieces are working and the installation is complete.
Preferences
Most application programs when attempting to dial using a DDE command are not able to specify
the line appearance for the call. A line appearance must be specified and can be different for the
different types of calls:
♦

Intercom Calls – dialing numbers with less than five digits.

♦

Local Calls – calls that match the local area code specified or calls with only seven digits.

♦

Long Distance Calls – any call with 10 or more digits (also indicate if a “1” needs to be added
when missing).

When an Intercom or [PDN] button is used to initiate calls, a prefix code is required to select an
outside line. Local and Long Distance calls have provisions for prefix digits to be dialed prior to
the number received from the software application.
Applications using DDE messages generally will dial the area code of the telephone number even
if it is a local call. By assigning a Local Area Code, StrataLink detects these calls, strips off the
Area Code of the telephone number, and dials using the “Local” appearance.
For example, if your Local Area Code is “714” and the application attempts to dial “714-5151234,” the program converts the number to “515-1234” before dialing.
It may be convenient to record a person’s extension number as part of the telephone number. When
dialed the 10 digit number is sent along with the extension number. As long as the number is stored
using any letter, such as “x,” all digits following are not dialed, e.g. “714-515-1234 x205” is dialed
as “515-1234”.
Some databases may not include a “1” as part of the dialed number. StrataLink can optionally
insert this missing digit by using the option “Add 1+ if Missing”. For example, if the application
attempts to dial a long distance call like “612-555-1234” (and your Local Area Code is “714”), this
option converts the number to “1-612-555-1234” before dialing.

13-8

Strata DK I&M

5/99

Computer Telephony Integration
Using StrataLink for CTI Connections

StrataLink provides a method for defining the format to present this number to the software
application. Any character other than “x” is included as part of the number, where “x” will be
replaced with the number received as part of Caller ID.
For example, if the international number plan is needed for the number, then a code for &H of
“1+(xxx) xxx-xxxx” is entered. When a number “6125551234” is received, it will be presented as
“1+(612) 555-1234”.

Computer Telephony
Integration

Incoming calls with Caller ID need to have the telephone number in a specific format for the
lookup function to work. Caller ID and ANI numbers are received from the telephone network as
10 digits. Many databases store the numbers in a more readable format using punctuation formats
by inserting hyphens, parenthesis, and spaces.

The Preferences dialog box is shown in Figure 13-3.

3542

DDE Commands
StrataLink accepts a number of DDE commands for controlling calls. StrataLink, wherever
necessary, offers more than one format for each command. The commands supported include Dial,
Answer, Hangup, Transfer, and Hold/Unhold.

Telephone System Events
Trigger Rules and Conditions
The Trigger Rules are established by the installer or user so that specific Actions can be performed
when an event occurs. The Triggering event can be any number of things (e.g., Call Ringing, Call
Connected, Call Holding, or Call Cleared). See Figure 13-5.

2657

Figure 13-5

Trigger Rules

The existing Trigger Rules can be displayed, edited, deleted or new rules can be added. Multiple
rules can be created and active at the same time.
Each rule uses the names assigned in the TAPI Service Provider to determine their application to a
given event. Buttons with the same name use the same rule written for that name. For example,
creating a Triggering Rule for “Call Ringing” on a [PDN] with multiple appearances can be
written to apply only to the PDN name, such as “3351.”
Specific [PDNs] can be labeled for “Call Ringing,” while other appearances may require a screen
pop whenever a call is connected. These other appearances could have the rule “Call Connected”
using  button. This prevents screen pops for calls which are directly ringing a particular
telephone button, while providing screen pops when a call is answered on another button on the
phone.

When adding or changing a rule, Filters and Conditions fields display on the Add/Change Trigger
Rule screen (see Figure 13-6):

Figure 13-6

Add/Change Trigger Rule

Filters
When the triggering event occurs, it may need to pass specific filters or conditions before the
Action is performed. The Filters (see Figure 13-6) are:
♦

Caller ID – required/not required. If there is no Caller ID associated with a call, you may not
want to have an Action performed. The most common example is “Screen Pop” where you
may select “any Number” to not perform the action until a Caller ID number has been
received. To trigger an event anytime a call rings, regardless of whether Caller ID is present,
you need select “none Required.”

♦

Trigger Delay – a short delay, expressed in tenths of a second, that will occur prior to the
action. The delay is needed to allow the Caller ID or other information to be received prior to
performing the action.

♦

Appearance – the Trigger can be used on any line or a specific line. If the same Trigger
applies to some lines but not to others, the rule must be entered for each line to which the rule
applies. Buttons having the same name need only one rule, e.g., two buttons labeled 205 would
have the same action whenever either ring when a Trigger Rule for Call Ringing is created for
appearance 205.

Conditions
Conditions (i.e., Phone State, shown in Figure 13-6) include performing the action “if not talking”
or “if trunk number is available.” You may not want to have an Action performed while you are
talking on a call. Again, a common example is to screen pop only “If Not Talking”. This prevents
an Action from occurring until you are finished with the call or placed it on hold.

Actions and Parameters
Actions are set up by the installer to perform a specific function (e.g., Screen Pop Goldmine, Pop
Telemagic, or Beep My Pager). These Actions can then be used as part of a Trigger Rule and
performed when a specific event occurs. The existing Actions can be displayed (Figure 13-7),
edited, deleted or new Actions added.

Type – Select the Action to be performed from the pull-down menu. Each Action has one or more
parameters that must be provided by the user/installer. These parameters often contain “tokens”
that enable the inclusion of real-time information (e.g., Caller Phone Number, Date, Time, etc.).
The choices are as follows:
♦

♦

DDE Execute – Sends a specific DDE command to the program you specify. This Action is
very flexible and can be used to communicate with many different types of programs for a
variety of purposes (e.g., Screen Pop). DDE Execute String parameters include:
♦

App Name – Used to set the DDE name of the application to receive the DDE event.

♦

App Topic – Used to set the DDE “Topic” for the application to receive the DDE event.

♦

DDE Execute String – This is the command executed by the application receiving this
DDE event. Typically this command includes token(s) so that real-time information is
included in the command string.

Computer Telephony
Integration

Action Name – Every event Action has a “Name” that you should set to describe the result the
action, such as “Beep My Pager.” This name is used in the Trigger Rules.

Show/Hide Test Params Button – When you set up an Action, it is always a good idea to
make sure the Action works correctly. The Show Test Params button exposes a set of
parameters (e.g., Calling Phone Number and Calling Name) that can be changed for verifying
the action defined.

➤ To execute the command, press the Do Test button.
The results of the action are displayed on the lower part of the window. Clicking on the open
part of the window clears the test results and the process repeated.
Some parameters contain token(s) that enable the inclusion of real-time information (like the
Caller Phone Number, Date, Time, etc.). The Tokens are described in Table 13-9.

TeleMagic Link
The TeleMagic program (from Telemagic, Inc.) communicates with StrataLink via a special link
called TeleMagic. The TeleMagic Link appears automatically each time StrataLink is accessed and
provides a means to set up and monitor communication between the two programs.
Important!

For this link to operate, the TeleMagic program must be loaded and operational.

If you select Auto Activate Link (see Figure 13-10), StrataLink automatically attempts to establish
the TeleMagic link periodically (every 30 seconds or so) until the connection is made. Once the
link is established, the Link Active light changes from Red to Green, dialing and Screen-Pop can
function. For Screen-Pop to work, the appropriate Trigger Rules must be set up.

3549

Figure 13-10

Telemagic Link

Pop TeleMagic
This instruction sends a “Pop” or “LookUp” command to TeleMagic with the configuration you
specify. This is used to Screen-Pop the TeleMagic contact manager when a call rings in. Pop
TeleMagic parameters are:
♦

Index Level – Tells TeleMagic the level on which to perform the search (e.g., 1, 2, 3, etc.).
Leaving this parameter blank causes the search to occur on the level in present use.

♦

Index Name – Selects the TeleMagic index to be used for the search. For Screen Pop this is
typically “TelePhone #”, but since the Indexes within TeleMagic are programmable, this could
be set to any appropriate index. The TeleMagic Link must be operational before you can make
this selection.

♦

Search String – This should be set to whatever string should be searched for using the above
two parameters. For Screen Pop, this is typically the Calling Phone number which would be
the token &P.

Testing TSPI Link
The TAPI dialog box provides a method for verifying the TAPI Driver is setup and operational. To
check the driver, select an appearance (e.g., Intercom) and click on each of the Pickup, Dial, and
Hangup keys individually. To complete the test, you should repeat this procedure for each line
appearance.
To access the setup screen for the Toshiba TAPI Service Provider, click on the Driver Setup button.

ISDN Interfaces

This chapter covers information on the ISDN Primary Rate Interface (PRI) and Basic Rate
Interfaces (BRI).

PRI and BRI Overview
♦

PRI is available on DK424 Release 4.0 systems with RCTUBA3/BB4, C3/D4, and E3/F4
processors; but unavailable for any other Strata DK systems or processors.
For PRI services, the Strata DK424 uses an RPTU PCB to connect to a Public Switched
Telephone Network (PSTN) PRI line using a UL listed Channel Service Unit (CSU) in most
locations in the U.S. Each RPTU provides 23B + D channels. The B-channels support CO
speech and data connections on the PSTN side only. The RPTU PCB is shown in Figure 14-2
on Page 14-6.

♦

BRI S/T is available for DK40i and all DK424 Release 4.1 processors including RCTUA4, but
not for any other DK systems.
For BRI S/T services, the DK424 uses an RBSU PCB; the DK40i uses TBSU and RBSU. Both
the RBSU and TBSU provide two BRI S/T circuits to connect to the PSTN BRI line using an
external UL listed NT1; or, on the station-side, connect to:
♦

S-type ISDN telephones and Terminal Equipment (TE-1-S)

♦

S-type Terminal Adapters (TA-S) with non-ISDN devices

Each TE-1-S and TA1-S device can support voice and/or RS-232 switched-circuit data as
shown in Figure 14-1. The station-side BRI S/T circuits are point-to-multipoint.
A subassembly (RBSS) can be attached to the RBSU for two additional BRIs for S-type
station-side connections only. The RBSU PCB and the RBSS subassembly are shown in
Figures 14-14 and 14-15 on Page 14-21. The combination of RBSU and RBSS uses only one
slot to provide up to four BRI S/T circuits.
Note

♦

Strata DK I&M

In DK424, each installed RBSU or RBSS circuit provides a 2B + D connection and uses a
system capacity of two station ports and two CO lines regardless of the circuit application,
even if the circuit is not actually connected. In the DK40i, each TBSU, RBSU, or RBSS
circuit uses two CO lines (no station ports) when configured for the CO side and two
station ports (no CO lines) when configured for the station side.

BRI U will be available on all Release 4.2 processors for the DK424, including RCTUA4, as
well as the DK40i.

5/99

14-1

ISDN Interfaces
PRI and BRI Overview

For BRI U services, the Strata DK424 uses an RBUU PCB. The RBUU provides two BRI U
circuits that connect directly to PSTN BRI lines; or, on the station side, connect to:
♦

U-type ISDN telephones and Terminal Equipment (TE-1-U)

♦

U-type Terminal Adapters (TA-U) with non-ISDN devices

Each TE-1-U and TA-U device can support voice and/or RS-232 switched-circuit data
depending on the device (see Figure 14-1). The station-side BRI U circuits are point-to-point.
A subassembly (RBUS) can be attached to the RBUU for two additional BRIs for PSTN and/
or U-type station connections. The RBUU PCB and the RBUS subassemblies are shown in
Figure 14-28 on Page 14-33 and Figure 14-29 on Page 14-34. The combination of RBUU and
RBUS uses only one slot to provide up to four U-type BRI circuits.
Each installed RBUU or RBUS circuit provides a 2B + D connection and uses a system
capacity of two station ports and two CO lines regardless of the circuit application, even if
the circuit is not actually connected.

Older Version(s): none

The DK424 Release 4.0 system supports the RPTU according to the common control units resident
in the system.
The RPTU cannot be installed in a system operating with the RCTUA4.

The RPTU requires installation of a customer-provided CSU in most locations of the U.S. Refer to
“CSU Requirements” on Page 14-3 for CSU installation.
Testing procedures (local and remote loop back) are in “Loop-back Testing” on Page 14-10.

ISDN Interfaces

Note

The RPTU’s LEDs indicate a continuous status of its operation. They are shown in Figure 14-3.
Table 14-5 on Page 14-7 lists the functions for each LED.
Switches, jumpers, and interface connectors are described in Figure 14-2.

RPTU Overview
The RPTU is a DS-1 divided into 24 TDM channels using standard T1 electrical signal format.
The RPTU’s D-channel is typically the 24th channel and can control the signaling of 23 of its own
B-channels and 24 B-channels of another designated RPTU. Each RPTU can also use its own
D-channel for control.
The RPTU’s in-service bit rate is 1.544 mbps (± 4.6 ppm), but during a maintenance session, the
rate may vary ± 32 ppm. The RPTU provides Binary 8-Zero Substitution (B8ZS) and ESF with
Framing Pattern Sequence (FPS) and Cyclical Redundancy Check (CRC) error checking in the
framing bits.
Note

The Embedded Operations Channel (EOC) which carries alarm notifications, statistics,
and error indications is not available with DK Release 4.0 software.

Extracting the Stratum-1 clock from the ISDN PRI, BRI, or T1 provider is the most common
method used to synchronize the RPTU PCB and the DK time switch to the public telephone
network. One RPTU, RBSU, RBUU, or RDTU T1 must extract the clock from the ISDN or T1
provider. The selected unit is designated as the “Primary” timing source in system Program *41-1.
For more information, refer to “Timing and Synchronization” on Page 14-11.
A dealer-supplied CSU must be installed between the ISDN PRI network line and the RPTU PCB
as shown in Figure 14-1. Some telephone companies supply the CSU and call it the Network
Interface Unit (NIU).

CSU Requirements
In the U.S., the CSU must be UL listed and comply with Part 68 of the FCC rules. It must also
comply with the limits for a Class A digital device, pursuant to Part 15 of FCC Rules. In Canada,
the CSU must be CSA certified.

Strata DK I&M

5/99

14-3

ISDN Interfaces
RPTU Interface Unit

The CSU is transparent to data, clock, and framing. It acts as a repeater, not a controller, for
timing. The CSU also acts as a signal regenerator and must be able to perform loop-back tests and
maintenance to both the network and DK RPTU. The CSU is the same type as used for T1 circuits
although it performs the function as NT1 for PRI ISDN in the ISDN reference model as shown in
Figure 14-1.

Slot Assignments
Up to eight RPTU PCBs can be installed in a DK424 system providing up to 188 PRI lines
(B-channels). If RPTU (PRI) and RDTU (T1) PCBs are installed in the same DK424, the
maximum combined PCBs cannot exceed the numbers provided in Table 14-1. The PCBs must be
placed in designated slots in each of the DK424 cabinets per Tables 14-2 and 14-3. The next
highest slot adjacent to the RPTU slot must be vacant.
Program 03, code 79 designates which cabinet slots contain RPTU PCBs. The maximum number
of cards and lines is listed in Table 14-3.

RPTU Installation
Before installing a RPTU PCB into a DK424, a number of system programs should be run. This
enables the RPTU to function immediately upon insertion. It is recommended that you run these
programs in the order listed in the DK Programming Manual (refer to the ISDN section) before
beginning installation.
➤ To install an RPTU PCB
1. Set the jumper wire plugs JP1 and JP2 (LB) to the OFF position.
2. Turn the DK424 system power OFF.
3. Insert the RPTU (component side facing right) into the appropriate slot (see “Slot
Assignments” on “Slot Assignments” on Page 14-4) and apply firm, even pressure to ensure
proper seating of connectors.
4. After installing the RPTU, gently pull the PCB outward. If the connectors are properly seated,
a slight resistance is felt.

ISDN Interfaces
RPTU Interface Unit

Cabling
To meet Part 15 of FCC Rules, ISDN PRI equipment must be connected using CAT5, Shielded
Twisted-Pair (STP) cabling between the CSU and the RPTU. CAT5 STP protects against cross
talk, Radio Frequency Interference (RFI), and/or Electro Magnetic Interference (EMI). STP
protects ISDN signal data while being transmitted through the cable and keeps the cable itself from
emitting EMI and RFI.
To avoid ground loops, connect only the RPTU end of the shielded cable to ground.
The DK grounds the CAT5 cable shield between the DK and CSU at the RPTU RJ45 jack. You do not have to connect the CSU ground drain. The CSU ground should
not be connected to the cable shield.

Important!

Shield continuity must be maintained from the RPTU to the CSU, particularly if using extension
connecting cables. Keep the cable as short as possible between the CSU and the PRI Demarcation
jack, because there is no shield between the CSU and the Demarcation jack.
Toshiba provides a cable kit (Part No. RPRI-CBL-KIT), that contains all that you need to connect
the network ISDN jack to the network side of most CSUs and the equipment side of the CSU to the
RPTU PCB. Depending on the manufacturer, the CSU may use DB15 or modular jacks. If the CSU
is equipped with the modular jacks, the DB15/modular adapters are not used. If this is the case,
make sure the CSU modular jacks are not shielded jacks. Refer to Figure 14-3 for more
information.
A detailed pinout diagram for the RJ-45 jacks (USOC RJ-48C or RJ-48X) and the modular cords/
adaptors is shown in Figure 14-2 on Page 14-6.
Cable Length
The distance between the RPTU and CSU or RPTU and other Customer Premise Equipment (CPE)
may vary (0~655 ft.). The RPTU must be equalized and its impedance must match the impedance
of the connecting cable. Set SW1 on the RPTU for the proper cable length as shown in Table 14-6.
Refer to Figure 14-2 for switch locations.

The modular pins are numbered left to right when looking into
the jack cavity with the locking clip down.
Shield continuity must be maintained between the RPTU and
the CSU, particularly on extension cords. Since there is no
shield continuity across the CSU and network jack, the cable
should be kept as short as possible.

RPTU Testing and Troubleshooting
Loop-back Testing
The RPTU has loop-back test jumpers that enable physical connections (cables/jacks/plugs)
between the RPTU, CSU, and the network PRI line to be tested (see Figure 14-6). The tests check
that the CSU receives and transmits the PRI signal properly in both directions. The test signals,
generated by the Network PRI provider, pass through the CSU and loop around the RPTU. The
RPTU sends the received test signal back through the CSU to the Network and the Network
detector checks for a valid signal.
➤ To perform the loop-back test
1. Remove the PRI modular cord from the RPTU RJ-45 jack and remove the RPTU from its card
slot.
2. Place the JP1 and JP2 jumpers to the LB-ON position. Install the RPTU with the DK power
OFF and the PRI modular disconnected from the RPTU RJ-45 jack.

3. Turn the DK power ON and connect the PRI modular cord to RPTU RJ-45.
4. After the PRI line and RPTU are synchronized, have the CO generate the loop-back test sign
(all “1s” or “0s”).
CAUTION!

Do not have the CO do a QRS loop-back test, because the test signal may cause
the DK to drop all calls and/or stop operating.

5. If the loop-back test fails, perform tests to isolate the problem with an ISDN test set, such as
the Sunbird, ISDN, or Trend DUET. In this case, the network PRI line is disconnected and the
test set is connected to the CSU network input jack. For testing details, refer to the ISDN test
set operating procedures.

Timing and Synchronization
The Digital Network is connected by timing clocks that synchronize the network and have various
degrees of precision (stratum levels). There are four stratum levels – 1 is the highest and 4 is the
lowest. They are associated with the following sources:
♦

Stratum – 1: Public Telephone Network clock

♦

Stratum – 2: #4 ESS Toll Switches

♦

Stratum – 3: #5 ESS Central Offices

♦

Stratum – 4: Digital PBXs

In the DK424, one PRI, BRI, or T1 PCB can be programmed to extract the Stratum clock signal. It
uses the signal as the DK system Primary clock reference. The clock provider should be a reliable
source, such as a Telco or common carrier (AT&T). All other PRI, BRI, or T1 lines connected to
the DK424 will be synchronized to the same clock provider. If the PRI, BRI, or T1 are not
synchronized to the same clock provider, the DK424 could experience “slip” problems.
Timing reference assignments for PRI, BRI, and T1 are made with the Program *42 series. The
timing or synchronization program determines how the DK424 digital voice or data transmission
path is synchronized with the far-end digital path. For proper PRI, BRI, and T1 operation, the
equipment at each end of the line must be synchronized.

Timing and Synchronization

The RCTU time switch is synchronized as the slave to the PRI, BRI, or T1 line (Line 1 in Figure
14-7). The DK424 PRI, BRI, or T1 in any slot number can be assigned as the Primary reference
(Program *42-1, DATA=1 for this PRI, BRI, or T1).
If a malfunction occurs and Primary reference synchronization is lost, the DK424 automatically
switches modes and synchronizes to the Secondary reference, provided that there is another PRI,
BRI, or T1 installed in the DK424. The Secondary reference PCB is assigned in Program *42-2.
