5. INSPECTION, PACKING and STORAGE

5.00 Inspection

5.01 When the system is received, examine all

packages and make careful note of any visible

damage. If any damage is found, bring it to the

attention of the delivery carrier and make the proper

claims.

5.02 Check the system against the purchase order

and packing slip. If it is determined that equipment

is missing, contact your supplier immediately.

5.03 After unpacking (and before installing), in-

spect all equipment for damage. If any is detected,

contact your supplier immediately.

CAUTION!

When handling (installing, removing, ex-

amining, etc.) printed circuit boards (PCBs),

do not touch the back (soldered) side or

edge connector. Always hold the PCB by

its edge whenever handling it.

5.10 Packing and Storage

5.11 When storing or shipping PCBs, be sure they

are packed in their original antistatic bags for pro-

tection against static discharge.

5.20 Required Tools

5.21 Installation of the PERCEPTION sys-

tems requires standard telephony tools. A 13mm

socket wrench and extension is recommended for

ease of expansion cabinet installation.

SYSTEM DESCRIPTION

1. PERCEPTION

1.00 Basic Equipment Cabinet

1.01 The basic equipment cabinet (NCEC-M) con-

sists of a single, free-standing cabinet mounted on

casters for easy movement. Once system installa-

tion has been completed and the cabinet has been

positioned, the casters can be locked to prevent

movement. The interior of the cabinet houses two

shelves for printed circuit card installation. A sepa-

rate area is provided for installation of the power

supply and peak load battery. MDF connections

are facilitated by amphenol connectors located on

the rear of the cabinet (Figure 2-1).

FIGURE 2-1—PERCEPTION BASIC CABINET

1.10 Expansion Cabinet

1.11 The expansion cabinet (NCEC-S) is a single

cabinet that mounts on top of the basic cabinet and

is secured in place with four bolts. The cabinet

houses two shelves for printed circuit card installa-

tion. MDF connections are facilitated by amphenol

connectors located on the rear of the cabinet (Fig-

ure 2-2).

1.20 Power Supply

1.21 The Main Power Supply (NPSA-M) consists

of a single metal chassis. In addition to the power

FIGURE 2-2—PERCEPTION EXPANSION CABINET

supply, this chassis contains the system ring gen-

erator and a charger/inverter for Reserve Power.

Located on the front of the chassis are a circuit

breaker and LED indicator for each power supply

output, and an AC power indicator, and the system

power switch. The battery switch is also on the front

of the NPSA-M.

2. PERCEPTION

2.00 Basic Equipment Cabinet

2.01 The basic equipment cabinet (LCEC-M) is a

single free-standing cabinet mounted on casters

for easy movement. The cabinet contains three

shelves for printed circuit card installation. A sepa-

rate area is provided for power supply and peak

load battery installation. MDF connections are fa-

cilitated by amphenol connectors located on the

rear of the cabinet (Figure 2-3).

2.10 Expansion Cabinet

2.11 The expansion cabinet (LCEC-S) is a single

cabinet that houses a single printed circuit card

shelf. MDF connections are facilitated by amphe-

nol connectors located on the rear of the cabinet

(Figure 2-4). Up to two expansion cabinets may be

added to the PERCEPTION basic equipment

cabinet.

2.20 Power Supply

2.21 The Main Power Supply (LPSA-M) consists

of a single metal chassis which contains the system

ring generator and charger/inverter for the Reserve

Power. A circuit breaker switch, LED indicators, AC

power indicator and system power switch are lo-

cated on the front of the chassis. For ease in

installation a handle is located at the top front of the

power supply (Figure 2-5).

3. PEAK LOAD BATTERY

3.00 The peak load battery will maintain call proc-

essing for a maximum of two minutes in the event

the PERCEPTION or PERCEPTION experi-

ences a power failure. Additionally, when the sys-

tem is under heavy usage the peak load battery will FIGURE 2-5—PERCEPTION

avoid power degradation by supplementing the -24

volts, maintaining a constant power level.

4. EXTENDED RESERVE POWER

4.00 The power supply is equipped, as a standard

feature, with an internal battery charger/inverter.

Full reserve power can be provided for any system

by connecting an appropriate, customer-supplied

24-volt battery pack. During normal operation, the

power supply charger/inverter will maintain the

proper charge in the battery pack. In the event of an

AC power failure, switchover to battery power will

be automatic. There will be no loss of system

operation as a result of power switchover. When

AC power is restored, switchback to the power

supply will be automatic.

4.01 Battery selection and size will depend on

system size and desired reserve operating time.

The maximum power consumption of the basic

cabinet is 11.5 amps at -24 VDC. For both a basic

and expansion cabinet configuration, the maxi-

mum will be 19 amps at -24 VDC. The selected

batteries must be compatible with the system’s

charger float voltage of 27.3 VDC.

5. POWER FAILURE/EMERGENCY TRANSFER

5.00 The function of the Power Failure/Emergency

Transfer Unit (DPFT) is to automatically connect

selected trunks to selected standard telephones in

the event of system failure while permitting normal

operation when the system is in service (maximum

of 1 per cabinet).

5.01 The DPFT is a self-contained module that

mounts externally to the basic cabinet, typically on

the MDF. Connections to the trunks, stations and

basic cabinet are made via two 50-pin amphenol-

type connectors (J1 and J2) on the DPFT (see

functional diagram in Figure 2-6).

5.02 The module consists of eight relays that are

normally operated, connecting the telephones to

NSTU circuits and the trunks to NCOU circuits. If a

power failure (or other emergency) occurs, the

relays release, connecting the telephones directly

to the trunks. Calls can then be placed from the

telephones over the CO trunks, bypassing the

system (which is out of service).

5.03 Power Fail Transfer (PFT) telephones con-

FIGURE 2-6—DPFT FUNCTIONAL DIAGRAM

nected to ground-start trunks must have ground

taps (tap buttons) in order to make outgoing calls

during power fail transfer conditions.

5.04 A transfer can be caused by a loss of power

or triggered manually by either of two buttons, one

of which is located on the underside of the atten-

dant console and the other on the front of the NPRU

PCB. A transfer that is caused by a power failure

will be reset automatically when power is restored;

a manual transfer must be reset manually.

5.05 When the DPFT is reset after a transfer,

existing PFT conversations will be protected. Indi-

vidual circuits will be restored only when they

become idle.

6. PRINTED CIRCUIT BOARD DESCRIPTION

6.00 Sixteen different types of PCBs are available

for use in both PERCEPTION systems (Figures 2-

7 & 2-8). The universal port architecture enables

multiple installation of trunk cards. The

PERCEPTION can support a maximum of 16

system via 2-conductor modular line cords. In ad-

dition, all models may be used at any or all stations.

8.10 Headset Upgrade (HHEU)

8.11 Each electronic/digital telephone may also

be upgraded to provide a modular headset jack

by installing a headset upgrade assembly. The

assembly consists of a small PCB (HHEU) which

installs on the main PCB, inside the electronic or

digital telephone, with a plug-in connector. Most

standard headsets are compatible with the HHEU

jack.

8.20 Attendant Console

8.21 The Attendant Console is available with face-

plates for the Business and Lodging/Health Care

applications. The console consists of a plastic

housing with handset/headset modular jacks. Two

horizontal rows of non-locking buttons, LEDs and

a 12-button dialpad enable call processing.

8.30 DSS Console

8.31 As an option both electronic and digital Direct

Station Selection (DSS) consoles can be used with

systems that do not require attendant consoles, or

require distributed call-handling positions. Two DSS

consoles per electronic/digital telephone, up to a

system maximum of eight DSS consoles, can be

installed.

8.40 Standard Telephone

8.41 Standard telephones can be mixed with elec-

tronic telephones as required by the user’s applica-

tion. Standard telephones can access all telephone

features using dial code access.

8.50 DDIU/PDIU

8.51 There are four types of Digital Data Interface

Units (DDIUs/PDIUs), DDIU-MAT, DDIU-MA, PDIU-

DI, and PDIU-DS. The DDIU-MAT is a built-in unit

that attaches directly to the bottom of a 10- or

20-button electronic telephone (replacing the base).

The PDIU-DI is a built-in unit that attaches directly

to the bottom of both digital telephones (replacing

the base). The DDIU-MA and PDIU-DS are stand-

alone units. Each unit is equipped with a female

RS-232C connector and operation switches. Both

the DDIU-MAT and DDIU-MA are equipped with a

power supply that connects to the DDIUs via a 6'

cord, and plugs into a standard 117 VAC wall outlet.

8.60 Paging Equipment

8.61 A customer-supplied paging amplifier can

work in conjunction with the system’s paging inter-

face and speaker zone switching to provide a

system paging capability.

8.70 Music-on-Hold

8.71 A standard interface enables a customer-

provided music source to be connected to the

system. This music is connected to all calls placed

in the hold, camp-on or call waiting condition by a

station or the attendant. The same music source

can also be used by the Automatic Wake-up fea-

ture for wake-up calls.

8.80 Universal Night Answer

8.81 Incoming calls, when the system is in night

operation, can be programmed to go either to a

night answer station or to a Universal Night Answer

device such as a bell or loud ringer. Any station user

can pick up a UNA call by either pressing a UNA

button on the telephone or by dialing an access

code. Up to two UNA zones can be programmed

per system, when the system is in tenant service.

8.90 Station Message Detail Recording

8.91 PERCEPTION automatically record call

data (such as call duration, digits dialed, originating

station and account codes) of calls made to and

from the system. Lodging/Health Care feature ac-

tivation (Automatic Wake-up, Message Registra-

tion, etc.) is also recorded. This data can then

output to a printer, recording device or call account-

ing system. The Lodging/Health Care feature audit

can be combined with SMDR or can be output

separately. SMDR helps the user reduce tele-

phone costs and monitor employee telephone

usage.

3) OPTION 3; Four digital DSS consoles: this

option uses one of the B channels for each of

the two circuits to interface up to four 1000-

series digital DSS consoles.

4) OPTION 4; Eight digital DSS consoles: this

option uses both B channels for each of the

two circuits to interface up to eight 1000-

series digital DSS consoles.

NOTE:

1. When using option 2 or 4, the next highest

number adjacent PCB slot cannot be

used. For example, if an NDKU is installed

in L01 or U01, the PCB slot L02 or U02

respectively, must be left vacant.

2. When using option 4, program the first

four DDSSs on circuits 1, 3, 5 and 7 on the

NDKU PCB. Program the second four

DDSSs on cirucits 1, 3, 5 and 7 on the

adjacent slot next to the NDKU PCB.

3. When using option 4, wire the first four

DDSSs to circuits 1, 2, 3 and 4 on the

NDKU PCB (these are the NDKU as-

signed DDSSs) and the second four

DDSSs to circuits 5, 6, 7 and 8 (these are

the DDSSs assigned to the adjacent slot)

on the NDKU PCB.

3.46 The NOCU PCB is installed at a rate of one

PCB for each group of eight electronic telephones.

There are no strapping options on this PCB. The

NOCU is installed in any of the line designated slots

L00 ~ L11 and/or L15 ~ L26 in PERCEPTION ,

and in any designated slots U00 ~ U31 in

PERCEPTION . If any of the eight circuits is not

used for Off-hook Call Announce, the remaining

circuits

slots or in any of slots L00 ~ L11 or L15 ~ L26 in the

PERCEPTION system. Two NDSUs can be

installed in the same cabinet. There are no straps

on this PCB. There are no C slots resident within

the PERCEPTION system so NDSU PCB instal-

lation will be in any U slot .

3.70 NEMU, NCOU, and NLSU

3.71 Trunk PCBs (NEMU, NCOU, and NLSU) may

be installed in any T slot. Additionally, up to 16 U

slots may also be used for trunk PCBs.

3.72 There are four circuits on the NEMU PCB,

and each circuit has its own set of straps (Figure 4-

18). On a circuit-by-circuit basis, strap the PCB as

follows:

1) For Type I/II operation:

2) For 2-wire/4-wire connection:

3) For 600-/900-ohm operation:

3.73 The NCOU PCBs have Ground-/Loop-start,

600/900-ohm termination, and 2dB pad strap se-

lections that must be made before they are installed

(Figure 4-19).

1) Each NCOU circuit is individually strapped for

either Ground Start or Loop Start operation.

The strapping location and options for each

circuit are shown as follows:

NOTES:

1. The GROUND START “EXTEND/NO EX-

TEND” options refer to “loop extenders”

on long trunk loops. If a battery boost is

used on the trunk, select EXTEND, other-

wise NO EXTEND should be selected.

2. The LOOP START “NORMAL/REVERSE”

options refer to the system’s ability to

detect a pre-ring supervision signal in the

form of a battery polarity reversal on the

CO TIP and RING.

If NORMAL is selected, the system will

not be sensitive to CO trunk polarity.

If REVERSE is selected, the CO cir-

cuit will be “made busy” when the CO

reverses polarity prior to ringing on an

incoming call.

2) Determine the proper impedance for each

trunk and then strap its NCOU circuit for either

600- or 900-ohm operation. Install the short-

a 2dB pad can be inserted into the line to

reduce the sidetone. The following table shows

the strapping position for each circuit to either

insert or remove the 2dB pad.

2) When the CO distance exceeds 2,000-ohm

loop resistance, Battery-to-Ground Dial Puls-

appropriate CO distance strapping (step 2)

has been made. The CO trunk loop resistance

values are arbitrary and are used as an initial

strapping guide. If the incoming digits are not

being detected properly, move the strap to the

next most sensitive position and test again for

proper operation.

3.80 NDTU

3.81 A maximum of two NDTU PCBs (Figure 4-21)

may be installed. The system must be equipped

with an NTWU-3 to ensure proper operation of the

NDTU. The NDTU is connected to the telco through

a customer-supplied Channel Service Unit (CSU).

A separate CSU is required for each NDTU. Each

NDTU has 11 DIP switches and 8 strapping op-

tions, which must be verified before installation.

nels, divided into groups consisting of four

channels each. The first group would fill trunk

slot T00, the second T01 with the remaining

four groups occupying trunk slots T02 ~ T05

for a total of six groups. For example, if eight

channels are active on the NDTU then slots

T00 and T01 are active i.e., no PCB may be

installed in slot T01. However, PCBs may be

installed in slots T02 ~ T05. Enable the appro-

type, either 64 Kbit or 256 Kbit, using the

the same manner, and they may be mounted on a

wall or any other flat, vertical surface to which the

base can be secured. When selecting the mounting

site, consider the electronic telephone’s weight and

the additional stresses to which the mounting will

be subjected.

5.12 Loosen the four captive screws securing the

electronic telephone's base, and remove the base

(Figure 4-24).

5.13 Using a cutter, remove the handset hanger

from the base. Insert the handset hanger in the slot

provided on the front of the telephone (Figure 4-

5.20 Off-hook Call Announce

5.21 The Off-hook Call Announce (OCA) feature

enables an electronic telephone to originate and

receive voice announcement when the station’s

handset is off-hook. Standard telephones can origi-

nate off-hook call announces, however, it cannot

receive them. A station user is allowed or denied

the ability to originate the Off-hook Call Announce

feature in the DCOS Program. In order to receive

the Off-hook Call Announce feature, PCBs are

required to be installed in each affected electronic

telephone and the cabinet.

5.22 A PCB called NOCU is required to be installed

in the cabinet. Each NOCU provides eight Off-hook

Call Announce circuits. This PCB takes up a station

slot. Therefore, for each NOCU installed, station

capacity is decreased by eight stations.

5.61 See the DSS Program in Section 200-255-

300,

Programming

, to input information concerning

the electronic DSS consoles.

5.62 The DSS console must be positioned adja-

cent to an electronic telephone (preferably an LCD

model). DSS consoles use 2-pair wiring and are

connected to the MDF via standard twisted-pair

telephone cables. The console connection is made

using only the data pair. An RJ25 modular connec-

tor should be attached to the instrument-end of the

telephone cable to permit connection to the DSS

console.

5.63 The overall length of the DSS console cable

run from the equipment cabinet must not exceed

500 feet (152.5 M), 24 AWG cable.

IMPORTANT!

When installing the DSS console cable, do

not run parallel to and within 3' of an AC

power line. Such power lines should be

crossed at right angles (90

°

) only.

5.64 DSS console(s) connection details are shown

5.71 See the DDIU Program in Section 200-255-

300,

Programming

, to input information concerning

Digital Data Interface Units. The system

must

be

told which type of DDIU (-MA or -MAT) is installed

at each location.

5.72 Digital Data Interface Units require only single-

pair wiring and are connected to the MDF via

standard twisted-pair telephone cables.

NOTE:

The DDIU-MAT requires an additional two-

pair for electronic telephone operation. (For

this reason, three-pair cable should be used at

locations where a DDIU-MAT may be installed.)

5.73 Digital Data Interface Unit connection details

are shown in Figure 4-37.

5.80 DDIU-MAT

5.81 The DDIU-MAT (Figure 4-38) mounts directly

on the bottom of an electronic telephone (forming a

single unit) as follows:

1) Remove the electronic telephone base (see

Paragraph 5.12).

2) Replace the telephone base with the DDIU-

MAT.

NOTE:

An electronic telephone with a DDIU-MAT

attached cannot be wall-mounted.

5.82 The DDIU-MAT requires four types of con-

nections for proper operation.

Power supply (to power outlet).

25-pin female RS-232C connector (to data de-

vice).

2-pair modular line cord (to electronic telephone).

3-pair modular connector (to LCEC/NCEC).

5.83 The power supply (provided) connects the

DDIU-MAT to a 117 VAC wall outlet. The 25-pin

female RS-232C connector interfaces with the cus-

tomer-supplied Data Terminal Equipment (DTE)

ON-Data device provides an Equip-

ment Ready signal to the DDIU (the

Terminal Ready LED will light only

when the signal is received).

OFF-Data device does not provide an

Equipment Ready signal to the DDIU

(the Terminal Ready LED will remain

lit continuously).

Switch 2 = not used.

Switch 3 = not used.

Switch 4 = ON (Enables automatic answer mode of

operation.)

Switch 5 = ON (Activates Automatic Data Release

feature. The data connection is auto-

matically released if no data is transmit-

ted for a period of 18 minutes.)

Switch 6 = 2400 BPS **

Switch 7 = 4800 BPS **

Switch 8 = 9600 BPS **

*A data path cannot be established if the

Terminal Ready light is OFF (even though a

DDIU-MA can be answered manually). The

Terminal Ready light must be ON to establish

a data path when answering manually.

**Select the appropriate speed for synchro-

nous data transmission. If the asynchronous

mode of operation is used, these switches

have no effect and the DDIU-MA will automati-

cally adjust to the appropriate speed (to a

maximum of 19.2 kbps).

5.95 Two switches on the DIUB PCB must be set

for either DTE or MODEM (DCE) operation. The pin

assignments shown in Paragraph 5.83 explain the

RS-232C cable signaling differences between DTE

and DCE devices. (Typically, a DTE is a terminal

device such as a personal computer or printer,

while a DCE is an intermediate device such as a

modem or protocol converter connected to a host.

Refer to the data device manufacturer’s documen-

tation for its signaling information.) Set the DIUB

PCB switches as follows:

1) Loosen the two screws found under the DDIU-

MA’s faceplate on the right side (top and

bottom) of the DIUA PCB (Figure 4-40).

2) Carefully separate the two halves of the DDIU-

5.87 Switches 2, 3, and 4 select the data speed for

synchronous transmission only.

Switch 2 = 2400 bps

Switch 3 = 4800 bps

Switch 4 = 9600 bps

5.88 If asynchronous operation is used, the

switches will have no effect and the data speed will

self-adjust to a maximum speed of 19.2 kbps or

less.

5.89 A power ON/OFF switch that appears on

some early DDIU-MAT models controls power to

the DDIU-MAT from the power supply. If the switch

is OFF, the DDIU-MAT will not function, but the

electronic telephone will continue functioning nor-

mally. When the switch is ON, both DDIU-MAT and

electronic telephone are functional. In later models,

the DDIU-MAT is operational when the power sup-

ply is plugged in.

IMPORTANT!

All connections to DDIUs (-MA or -MAT)

must observe correct tip and ring polarity

for proper operation.

5.90 DDIU-MA

5.91 The DDIU-MA is a stand-alone unit that incor-

porates both the manual dialing and auto-answer-

ing features of the DDIU-MAT, but is used as a data

transceiver only.

5.92 The DDIU-MA has several internal and exter-

nal switches that must be set for proper operation.

5.93 The power ON/OFF switch, on the bottom of

the DDIU-MA, must be turned ON for the DDIU-MA

to operate. When the switch is ON, an LED on the

front faceplate will light.

5.94 The DDIU-MA’s faceplate must be removed

to set the internal DIP switches. Remove the face-

plate by carefully lifting the lower right corner and

then pulling the faceplate away from the base. Set

the following parameters as required at switch S26

on the internal DIUA PCB (Figure 4-40):

3) If the DDIU-MA is to be connected to a DTE,

both switches must be in the DTE position. If

it will be connected to a DCE, both switches

must be in the MODEM position.

EQUIPMENT INSTALLATION

6.00 Digital Telephone Connections

6.01 See the DEKT Program in Section 200-255-

300,

Programming

, for instructions on program-

ming digital telephones. When installing digital

telephones, digital DSS consoles, PDIU-DI, or PDIU-

DS, Version D.04 software or higher must be in-

stalled. The system must be told the type of digital

telephone (20-button, or 20-button with LCD) and

what button assignment is required.

6.02 Digital telephones are connected to the MDF

via standard twisted-pair jacketed telephone cable.

(Single-pair wiring is required; however, 2- or 3-pair

wiring is strongly recommended to permit expected

distances for data, spare pair, etc.) To accommo-

date the digital telephone line cord, terminate the

cable in a modular station connector block (RJ25)

at the station location. The standard modular digital

telephone cord length is 7 feet (the maximum

allowed length is 25 feet).

6.03 The overall length of the digital telephone

cable run from equipment cabinet to phone must

not exceed 1,000 feet (305 M), 24 AWG cable.

IMPORTANT!

When installing the digital telephone cable,

do not run parallel to and within 3 feet of an

AC power line. Such power lines should be

crossed at right angles (90

°

) only.

6.04 Digital telephone connection details are shown

in Figure 4-42.

6.10 Digital Telephone Wall Mounting

6.11 Both telephones are wall-mounted in the same

manner, and they may be mounted on a wall or any

other flat, vertical surface to which the base can be

secured. When selecting the mounting site, con-

sider the digital telephone’s weight and the addi-

tional stresses to which the mounting will be sub-

jected.

6.12 Loosen the four captive screws securing the

with a single-pair station line cable that plugs into

the modular connector on the back of the base (see

Digital Data Interface Unit Connections, Paragraph

5.70).

, to input information concern-

ing the digital DSS consoles.

6.82 The DSS console must be positioned adja-

cent to a digital telephone (preferably an LCD

model). DSS consoles use 2-pair wiring and are

connected to the MDF via standard twisted-pair

telephone cables. An RJ25 modular connector

should be attached to the instrument-end of the

telephone cable to permit connection to the DSS

console.

6.83 The overall length of the DSS console cable

run from the equipment cabinet must not exceed

1000 feet (304 M), 24 AWG cable.

IMPORTANT!

When installing the DSS console cable, do

not run parallel to and within 3' of an AC

power line. Such power lines should be

crossed at right angles (90

°

) only.

6.90 DIGITAL DATA INTERFACE UNIT

(PDIU)

6.91 The Perception with D.04 software

provides two new style digital Data Interface

Units (DIUs) that enable digital telephone users

to simultaneously transmit and receive data on

the same NDKU station port and wire pair while

communicating on a voice call. One unit, called

the integrated DIU (PDIU-DI) replaces the digital

telephone’s base; the other unit is a small self-

contained box called the stand-alone DIU (PDIU-

DS). Each DIU is powered by the NDKU PCB it is

connected to; therefore, no external power is

required.

6.92 Both PDIUs can be connected to standard

Electronic Industries Association (EIA) RS-232

asynchronous serial data devices. EIA devices

are divided into two categories:

Data communication equipment (DCE). Com-

mon DCE devices are modems and some

printers.

Data terminal equipment (DTE). Common DTE

devices are personal computers, ASCII termi-

nals, and some printers.

The PDIU-DI operates like a DCE, and it con-

nects 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 a

DTE device. In most applications, DTE and DCE

devices exchange data between each other via

the standard RS-232 cable connection.

6.93 PDIUs can function with DCE and DTE

devices at data speeds of up to 19.2kbps; how-

ever, keyboard dialing using AT commands (from

a PC or a terminal connected to a PDIU) is limited

up to 9.6kbps. PDIU data transmission speed is

set by the first AT command that the PDIU re-

ceives once it is in the command mode. The

transmission speed is transparent to the PDIU if

data is being sent via manual dialing or if the

PDIU is receiving calls.

NOTES:

1. See the DDIU Program in Section 200-

255-300 for information on programming

the Digital Data Interface Units. The sys-

tem must be told which type of PDIU (-DI

or -DS) is installed at each location.

2. Digital Data Interface Unit (PDIU-DI and

PDIU-DS) connection details are shown

in Figure 4-42, the Digital Telephone

Connection diagram.

commands, communications software or

some program that performs “terminal

emulation” must be loaded in the com-

puter. The AT commands cannot be issued

from the computer’s operating system

prompt.

6.100 Common DIU Connections

6.101 The block diagram in Figure 4-51 illustrates

common DIU connections. In this example, PDIU-

DIs are connected to laptop personal computers

(PC1 and PC2), and the PDIU-DS’s are connected

to a serial printer and modems. The PC users can

transfer files internally, print files on the same

printer, and access the modem to send/receive

data to/from an external personal computer, or dial

up a data service.

6.102 To access these devices, a data call connec-

tion must be established between the DIUs. This is

accomplished by dialing the destination DIU from a

digital telephone dialpad or from a PC keyboard

using standard AT dial commands. PDIU-DIs have

port and DATA DN assignments adjacent to the

digital telephones that they are connected to, while

PDIU-DS’s have separate port and DATA DN as-

signments. The DN and DATA buttons on the

digital telephone tell the system whether a voice or

data call is being made: The DN button indicates

voice calls, and the DATA button indicates data

calls. When dialing from a keyboard with AT com-

mands, enter ATD for data calls. Only DATA calls

can be made through keyboard dialing.

6.103 Installation instructions for these devices are

provided in Paragraphs 6.140 ~ 6.160. Call paths

and scenarios for four types of data calls are

provided in Paragraphs 6.181 ~ 6.185. Step-by-

step data calling procedures are provided in the

PDIU User Guide

.

6.110 EIA Interface Leads (Signals)

6.111 Both DIUs operate with the ten standard EIA

RS-232 interface leads (signals) on which signal-

ing data is transmitted and received. DIUs connect

to serial data devices’ signals with standard RS-

232 cables, available from telephone supply stores.

The PDIU-DI/PDIU-DS Data Units require ten sig-

nals for some applications, but can function with

eight, using modular cords and connectors with

RJ45/DB25 adapters for other applications (Fig-

ures 4-52 and 4-53). If uncertain which signals are

necessary for an application, all ten should be

connected.

IMPORTANT NOTES!

1. The 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 (see Figure 4-54).

2. In the descriptions below, when a sig-

nal 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. If required by local

codes, the FG may be connected to

external ground.

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 later in this sec-

tion) 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).

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 generates the

RTS signal, the DIU DIP switch SW1-4

should be set to ON to inform the PDIU.

Sometimes, the DTE/DCE device may

use RTS/CTS for Ready/Busy-type flow

control. In these cases, DIP switch SW1-

4 should be set to OFF (see Figure 4-55

for the DIP switch information).

INSTALLATION INSTRUCTIONS

SECTION 200-255-204

FEBRUARY 1992

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 DTE device. The

DCE device sends this signal, only when

it receives the RTS signal from the DTE

device. Sometimes, the DTE/DCE de-

vice may use RTS/CTS for Ready/Busy-

type flow control; in these cases, dip

switch SW1-4 should be set to OFF (see

Figure 4-55 for the DIP switch informa-

tion).

Data Set Ready (DSR, Pin 6): When

connected to the communication chan-

nel 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 SW1-1 is set to OFF,

DSR and DCD (see DCD description

below) will be ON continuously; if the

switch is set to ON, the PDIU generates

DSR only after receiving the DTR signal.

Sometimes, DTE/DCE devices use DTR/

DSR for Ready/Busy flow control; in these

cases, DIP switch SW1-2 should be set

to OFF (see Figure 4-55 for the DIP

switch information).

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.

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 re-

quire 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. To

set the DCD on continuously, PDIU DIP

switch SW1-2 is set to ON; if set to OFF,

the DCD signal will be on during the

communication state only. SW1-2 is set

to OFF when the DTE/DCE uses the

DTR/DSR signals for Ready/Busy flow

control (see Figure 4-55 for the DIP switch

information).

Data Terminal Ready (DTR, Pin 20):

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 re-

ceive data. Sometimes, DTE/DCE de-

vices use DTR/DSR for Ready/Busy flow

control; in these cases, DIP switch SW1-

2 should be set to OFF (see Figure 4-55

for the DIP switch information).

Ring Indicator (R1, 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

PDIU DIP switch SW1-3 is set to ON, the

RI signal will be on continuously; if the

switch is set to OFF, the RI signal will be

one second on/three seconds off.

6.120 DIP Switch Options

6.121 Each of the PDIU-DI and the PDIU-DS data

units has 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 4-55).

SW1-1: Normally, this switch is set to OFF.

When set to ON, it automatically disconnects

devices from the PDIUs if no data is exchanged

between the devices and PDIU for an interval of

eight to nine minutes.

SW1-2: This switch is placed in the ON position

when the PDIU-DI (or PDIU-DS configured like a

DCE) must hold DCD and DSR on continuously.

Sometimes, a computer may use DTR/DSR for

Ready/Busy flow control; in these cases, this

switch should be OFF. Consult the DTE/DCE

device or application software documentation to

determine which type of flow control is required.

SW1-3: The PDIU-DI (or PDIU-DS configured as

a DCE) sends the Ring Indicate signal (RI) to the

computer to tell the computer (DTE) that the

PDIU is receiving an incoming call. SW1-3 should

be set to ON for the DCE to send RI continuously,

and OFF to send at one-second-ON/three-sec-

onds-OFF intervals. Consult the DTE/DCE de-

vice or application software documentation to

determine which type of flow control is required.

SW1-4: This switch is placed in the ON position

if the computer does not output the RTS signal.

Sometimes, the computer may use RTS/CTS for

Ready/Busy flow control; in these cases, SW1-4

should be OFF. Consult the DTE/DCE device or

application software documentation to deter-

mine which type of flow control is required.

6.130 PDIU-DI INSTALLATION

6.131 The PDIU-DI (Figure 4-56) mounts directly

on the bottom of a digital telephone (forming a

single unit) as follows:

1) Remove the digital telephone base (see Para-

6.140 PDIU-DI to Personal Computer (PC)

Installation

6.141 The 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 DTE

devices; PCs transmit data on the TD lead and

receive data on the RD lead. Follow the steps below

to install the PDIU-DI to a DTE or DCE PC:

NOTES:

1. Use the steps below when installing an

ASCII terminal, or any other DTE device to

a PDIU-DI.

2. The PDIU-DI can connect to a DCE com-

puter or any other DCE-type device using

a specially configured RS-232 cable or

adapter; however, this application is rarely

required.

1) Install the digital telephone that is to be

equipped with PDIU-DI in accordance with the

instructions in Section 200-255-205, MDF

Arrangement, Paragraph 1.01 and in Figure

5-2.

2) Install the PDIU-DI in the digital telephone’s

base in accordance with the instructions in

Paragraph 6.130.

NOTE:

The PDIU-DI operates only as a DCE device;

therefore, unlike the PDIU-DS, it has no inter-

nal jumpers.

3) Connect the appropriate RS-232 cable be-

tween the PDIU-DI DB-25 female connector

and the PC’s appropriate asynchronous serial

communications port connector.

IMPORTANT NOTE!

Check the PC manufacturer’s serial com-

munication port interface documentation

for correct RS-232 pin requirements; re-

quirements vary with each manufacturer.

The number of EIA RS-232 signals re-

quired (8, 9, or 10 wires) will depend on

the application. When EIA signal require-

ments are not known, connect the 10 EIA

signals listed in Paragraph 6.110. Fig-

ures 4-57, 4-58, and 4-59 provide dia-

grams for connecting RS-232 cables be-

tween PDIU-DIs and a Toshiba printer

and laptop computer, IBM XT-type and

AT-type personal computers.

4) Set the PDIU-DI/PDIU-DS DIP switch (SW1-

1 ~ 4) for the desired application. Figure 4-55

shows the DIP switch locations and Para-

graph 6.120 describes the switch functions.

5) Access the DEKT and DDIU Programs for

PDIU port connection and data button assign-

ments.

The port number entered for the PDIU-DI

in the DDIU Program is the adjacent port

number of the digital telephone.

Example: DKT port number = L024, PDIU-

DI port number = L034

IMPORTANT NOTE!

The eighth port (circuit) of the NDKU can-

not be used for data switching connec-

tions (PDIU-DI or PDIU-DS).

6.150 PDIU-DS To Printer Installation

6.151 PERCEPTION enables serial printers

(laser, dot matrix, or other types) to be connected

to stand-alone data interface units (PDIU-DS). Digi-

tal telephones equipped with PDIU-DI and Elec-

tronic Telephones equipped with DDIU-MAT can

share access to these printers. Serial printers oper-

ate 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.) Follow the steps

below to install the PDIU-DS to a serial printer.

INSTALLATION INSTRUCTIONS

SECTION 200-255-204

FEBRUARY 1992

NOTES:

1. Only serial printers that conform to EIA

RS-232 signaling requirements can be

connected to PDIU-DS units.

2. In rare applications, printers can be con-

nected to PDIU-DIs. Refer to the printer’s

installation instructions.

1) Consult the serial printer’s documentation,

and determine if the printer operates as a DCE

or DTE device:

As a DCE device:

a) Disassemble the PDIU-DS, and con-

figure it to operate like a DTE device

by placing the jumper plugs P1 ~ P9

in the “B-C” (MODEM) position.

b) Reassemble the PDIU-DS, and mark

“B-C” on the bottom identification la-

bel for future reference. (Paragraph

6.170 provides PDIU-DS disassem-

bly/assembly instructions, and Fig-

ure 4-54 provides jumper plug infor-

mation).

As a DTE device:

It may not be necessary to disassemble

the PDIU-DS, since it comes direct from

the factory configured as a DCE device.

However, if uncertain,

a) Disassemble the PDIU-DS, and verify

that jumper plugs P1 ~ P9 are in the

“A-B” (DTE) position for DTE opera-

tion.

b) Reassemble the PDIU-DS and mark

“A-B” on the bottom identification la-

bel for future reference. (Paragraph

6.170 provides PDIU-DS disassem-

bly/assembly instructions, and Fig-

ure 4-54 provides jumper plug infor-

mation).

2) Connect the PDIU-DS to the appropriate NDKU

circuit in accordance with the wiring diagrams

in Section 200-255-205.

3) Connect the appropriate RS-232 cable be-

tween the printer and the PDIU-DS.

4) If steps 2 and 3 are properly done, the POWER

and READY LEDs on the PDIU-DS should

light when the printer is turned on.

IMPORTANT NOTE!

Check the printer’s serial documentation

for correct RS-232 pin requirements. The

requirements vary with each manufacturer.

5) Refer to the DDIU Program for PDIU-DS data

assignments.

IMPORTANT NOTE!

The eighth port (circuit) of the NDKU can-

not be used for data switching connection

(PDIU-DI or PDIU-DS).

6.160 PDIU-DS To Modem Installation

6.161 With D.04 software, PERCEPTION

enables asynchronous-type (not synchronous)

modems to be connected to PDIU-DS’s. This al-

lows PDIU-DI-equipped digital telephones that are

connected to PCs, terminals, and other devices to

share access to a modem.

6.162 Modems can be accessed internally for out-

going data calls or externally for incoming data

calls. Modems operate as DCE devices, so the

PDIU-DS must be configured to operate like DTE

devices. The installation example in Figure 4-51

shows that two modems are connected to NSTU

ports; however, the line side of modems can be

directly connected to a dedicated CO line. The

modem connects to the PDIU-DS with a standard

RS-232 connector; the PDIU-DS line side (RJ-11

connector) always connects to its own individual

NDKU port. Use the following instructions to con-

nect modems to PDIU-DS’s.

1) Configure the PDIU-DS as a DTE device:

a) Disassemble the PDIU-DS, and place

jumper plugs P1 ~ P9 in the “B-C” position

(MODEM).

b) Reassemble the PDIU-DS, and mark “B-C”

on the bottom identification label for future

reference (Paragraph 6.170 provides

4-52

INSTALLATION INSTRUCTIONS

SECTION 200-255-204

FEBRUARY 1992

PDIU-DS disassembly/assembly instruc-

tions, and Figure 4-54 provides jumper

plug information).

2) Connect the PDIU-DS to the appropriate NDKU

circuit in accordance with the wiring diagrams

in Section 200-255-205.

3) Connect the appropriate RS-232 cable be-

tween the modem and the PDIU-DS. Figure

4-60 shows an example of PDIU-DS to a

Hayes modem RS-232 connection.

IMPORTANT NOTE!

All ten 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.

4) Connect the line side of the modem to a NSTU

standard telephone circuit, or a dedicated CO

line (Consult the modem’s documentation to

connect it to a CO line). Section 200-255-205

provides NSTU station port wiring informa-

tion.

5) Refer to the DDIU Program for PDIU-DS

connection assignments.

IMPORTANT NOTE!

The eighth port (circuit) of the NDKU can-

not be used for data switching connec-

tions (PDIU-DI or PDIU-DS).

6.170 PDIU-DS Disassembly and Assembly

6.171 To set the jumper plugs P1 ~ P9 on the sub-

assembly inside the PDIU-DS for DCE or DTE

operation, the PDIU-DS must be disassembled

(Figure 4-61). Disassemble the PDIU-DS in accor-

dance with the steps in Paragraph 6.172.

6.172 Disassembling the PDIU-DS

1) Remove the four screws securing the bottom

panel to the rest of the unit. These screws are

not captive, so place them together where

they can be easily accessed.

2) Remove the bottom panel.

3) Remove the PCB by lifting the back panel from

its side grooves.

4) Turn the PCB over and set jumper plugs P1 ~

P9 as follows:

If the PDIU-DS is connected to a DTE,

set the plugs to the “A-B” position.

If the PDIU-DS is connected to a DCE

device, set the plugs to the “B-C” posi-

tion.

6.173 Assembling the PDIU-DS

1) Position the back panel to the PCB.

2) Slide the back panel down into its side grooves.

3) Attach the bottom panel, and secure it with the

four noncaptive screws.

6.180 PDIU-DI/PDIU-DS Installation Tests

6.181 Figures 4-62 ~ 4-65 provide tests for four

PDIU call applications. The telephone and port

9.21 Install Reserve Power as follows (Figure 4-

68):

1) Place the customer-supplied battery pack

where it will be located.

CAUTION!

Batteries can emit fumes that are poison-

ous to people, potentially explosive, and

corrosive to electronic components. Lo-

cate batteries so that any fumes are ade-

quately vented per local fire codes.

2) Place the POWER switch (on the front of the

main power supply) in the OFF position and

remove the AC power cable from the outlet.

3) Connect the battery pack leads (customer-

supplied) to TB2 BAT on the NPSA-M or

6) Plug the AC cable into the outlet and turn the

POWER switch ON.

9.30 Paging Equipment

9.31 By combining a single customer-supplied pag-

ing amplifier with the system’s paging interface and

speaker zone switching, it is possible to provide a

paging system of up to five zones with All Zone

Page capability.

9.32 Figures 4-69, 4-70 and 4-71 show possible

paging arrangements. As a standard feature (part

of the NPRU PCB), the system provides a 600-ohm

output to a paging amplifier. If more than one

paging zone is required, the output of the amplifier

can be routed back to the NPRU PCB where it will

be switched to one of five sets of speakers. The

speaker operated is determined by the access

code dialed by the station user. The actual access

code is assigned in software (see Section 200-255-

300,

Programming

).

9.33 An All Page code can also be defined in

software. When that code is dialed, all relays will be

activated simultaneously to permit paging to all

speaker zones.

9.34 If the power loads of the different zones are

such that a single amplifier is not suitable, multiple

amplifiers (up to one for each zone) can be con-

nected as shown in Figure 4-71.

9.35 If music is to be broadcast over the paging

system, two arrangements are possible:

1) If the music is supplied from a separate ampli-

fier (as in Figures 4-70 and 4-71), it can be

connected between the speaker common line

and the PG GND input to the NPRU

(PERCEPTION J2/J502 and pin 2 or

PERCEPTION J1/J2 and pin 2). The music

will be connected to all speaker zones when

no page is in progress. When a page access

pins 4 and 29 (Br-W and W-BR) of J2 or J502 / J1

or J2 for the PERCEPTION systems, respec-

tively (see Tables 5-4 and 5-10). The input imped-

ance is 600 ohms. (This cannot be the same

source used to provide music over external speak-

ers.)

9.43 Adjust the MOH volume with the MOH vol-

ume control on the front of the NPRU PCB. Maxi-

mum volume is limited by internal circuits in order

to comply with FCC regulations.

9.50 Universal Night Answer

9.51 The Universal Night Answer (UNA) feature

provides an output of interrupted ringing voltage

(85 +10 VRMS, 20 Hz superimposed on -24 VDC)

whenever the system is in Night Service and an

incoming call is received by a trunk designated for

UNA. Any station user, upon hearing the chime or

bell, can dial the UNA access code and be con-

nected to the caller.

9.52 The ringing voltage output is intended to

control a strategically located chime or loud ring-

ing bell. The available power is five ringer equiva-

lents.

9.53 Two UNA zones can be installed in tenant

systems. Either zone can be assigned in pro-

code is dialed, the music is disconnected from

the zone and the page amplifier output is

connected.

2) If the music is connected to a second input of

the paging amplifier (Figure 4-69), the PG1

control lead (J2 and J502 pin 27 or J1 and J2

for PERCEPTION , respectively) can be

connected to the MUTE terminal of the page

amplifier music channel. When any page ac-

cess code is dialed, a ground output is applied

to the PG1 lead to mute the music.

9.36 All paging connections are made at the J2

and J502 or J1 and J2 connectors on the

PERCEPTION systems, respectively. The con-

nectors are located on the rear of the basic and

expansion cabinets. See Tables 5-4 and 5-10 for

details.

9.40 Music-on-Hold

9.41 A Music-on-Hold (MOH) interface is a stan-

dard feature on the system. The circuitry occupies

part of the NPRU PCB. If MOH is equipped, it will be

heard by any station or trunks on-hold in the sys-

tem, or by any trunk put into the camp-on state.

9.42 A tuner or other program source, supplied by

the customer, is connected to the MOH input via

9.60 Station Message Detail Recording

9.61 The Station Message Detail Recording

(SMDR) feature enables a business to monitor and

control its telephone costs. Data can be collected

for each outgoing and/or incoming trunk call. Each

such call generates a call record that is output at the

SMDR connector on the connector panel at the

upper rear of the LCEC-M or NCEC-M. (In Lodging/

Health Care applications, data specific to those

applications are included in the SMDR output.)

9.62 SMDR output can be connected to a variety of

gramming to either tenant. For PERCEPTION ,

connections to the UNA ringing signal are via

pins 12 and 37 (O-BK, BK-O) of J2. This connec-

tion is to J502 in the expansion cabinet for UNA

Zone 1 (see Tables 5-4 and 5-10). UNA zone 1

requires a second NPRU PCB in the expansion

cabinet.

9.54 UNA connections for PERCEPTION are

made at pins 12 and 37 connectors J1 and J2 on

the basic cabinet. A second UNA device requires a

second NPRU to be installed in the basic cabinet.

9.70 The recording criteria and account code length

are defined in DMDR Program (see Section 200-

255-300,

Programming

).

9.71 Each time a trunk is seized, data is collected

for that call until the trunk is released. This data is

output at the SMDR port in the following format (see

Figure 4-73).

Call accounting equipment to provide custom-

ized call reports.

9.63 Refer to the external device manufacturer’s

documentation for information on its SMDR con-

nector pin assignments.

9.64 The SMDR output speed can be set for either

300 bps or 1200 bps by the MDR switch on the front

panel of the LCCU PCB (Figure 4-72). SMDR pin

assignments are as follows:

9.65 The code used by SMDR is standard 7-level

ASCII using one start bit, one stop bit and one parity

bit (even parity).

9.80 Lodging/Health Care Data Audit

9.81 The Lodging/Health Care Data Audit feature

enables the user to record and analyze the registra-

tion and operation of specific features in Lodging/

Health Care applications.

9.82 Lodging/Health Care audit data is output at

either the SMDR (as part of the SMDR printout) or

the TTY (as a separate report) connector on the

upper rear of the basic cabinet. (Because the TTY

connector is required for on-site programming and

maintenance procedures, it is recommended that

the SMDR port be used.) The selection of data to be

output and the connector choice (TTY or SMDR)

are software-controlled (see DHMF Program in

Section 200-255-300,

Programming

).

9.83 The SMDR or TTY output can be connected

to either:

A local 80-column printer for an on-line printout.

Compatible call accounting or property manage-

ment interface equipment, supplied by another

vendor.

9.84 The audit pin-out assignments at the SMDR

or the TTY connector are not identical. Refer to

Paragraph 9.64 for the pin-out assignments of each

connector. For instruction on connecting equip-

ment provided by other vendors, refer to the

manufacturer’s documentation.

9.85 The audit data output rate can be set for either

300 bps or 1200 bps (depending on the configura-

tion of the receiving equipment) at either the SMDR

switch or the TTY switch on the front panel of the

LCCU PCB.

CAUTION!

If the TTY connector is used for program-

ming and maintenance operations, (either

with an on-site teleprinter or remotely via a

modem) be careful not to change the data

rate setting of the TTY switch so that it is

incompatible with programming equip-

ment.

9.86 Figure 4-74 shows a typical Lodging/Health

Care audit printout. Notes on the figure explain the

possible value for each column.

10. SYSTEM POWER UP

10.00 General

10.01 Upon initial power up, the system will

automatically load its operating system and cus-

tomer data from the disk. Two sets of disks are

provided with each system; one set should always

be mounted in the drive, the other kept as a spare.

10.02 Activate the system as follows:

1) Be sure the main power switch on the NPSA-

M is in the OFF position, and plug the AC cord

into the outlet.

2) If the system uses D.02 or later version soft-

ware, insert the SYSTEM disk in FDD0. If two

drives are used, insert the MAINTENANCE

disk (Figure 4-75) in FDD1. If the system uses

D.01 software, insert the program disk in FDD0.

3) Turn the main power switch on the NPSA-M to

the ON position.

4) The floppy disk will run: LED will come on.

LCCU MAJ ALARM LED will be on.

NPRU PFT LED will be on.

CHAPTER 5

MDF ARRANGEMENT

1.00 All connections from the system to external

equipment, such as trunks, stations, data interface

units, etc., are made via a customer-provided main

distribution frame (MDF).

1.01 Cables with male amphenol-type connectors

are attached to the connector panels of the basic

and expansion cabinets and secured with the con-

nector locking bar (Figure 5-1). Plastic cable clamps

are provided along the base of the basic cabinet to

secure cables. The opposite ends of the cables are

then terminated on 66-type quick-connect terminal

blocks on the MDF (split blocks with bridging clips

should be used to allow for fault isolation). A typical

MDF layout is shown in Figure 5-2. Connect each

cable from the basic and expansion cabinets to one

side of the block and external equipment cables to

the other side. Use bridge clips to make the connec-

tions.

1.02 FCC regulations prohibit unregistered equip-

ment from being terminated on the same block as

CO trunks. It is good practice to separate trunks

from all other equipment at the MDF.

1.03 Table 5-1 shows the connector-card slot

match-up. Table 5-2 lists the connector cables

required for the system. Each connector provides

the interface for only a single card slot.

1.04 To protect against transient voltages and

currents beyond what is provided by simple primary

protectors, the Underwriters’ Laboratories’ Standard

1459 2nd edition lists secondary protectors that

should be installed if there are outside leads. See

Figure 5-3 for these conditions.
