General End User Information
The Strata CTX100 or CTX670 Digital Business Telephone System is registered in
accordance with the provisions of Part 68 of the Federal Communications
Commission’s Rules and Regulations.
FCC/ACTA Requirements
Means of Connection: The Federal Communications Commission (FCC) /
Administrative Council Terminal Attachments (ACTA) has established rules which
permit the Strata CTX100 or CTX670 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,
log onto www.toshiba.com/taistsd/locator.htm or call (800) 222-5805 and ask for a
Toshiba Telecom Dealer.
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 CTX100 or CTX670 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 CTX100 or CTX670
system to the telephone network, the telephone company may request the following:
1. Your telephone number.
2. FCC registration number:
•Strata CTX100 or CTX670 may be configured as a Key, Hybrid or PBX
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.
•CTX28 FCC/ACTA Registration Numbers
Hybrid: CJ6MF03BDTCHS28, fully-protected multifunction systems
Key: CJ6KD03BDTCHS28, key systems for analog applications
•CTX100 Registration Numbers

•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.
3. Network connection information USOC jack required: RJ11/14C,
RJ21/2E/2F/2G/2HX/RJ49C (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.)
Important Notice — Music-On-Hold
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

Strata CTX28 Overview 1
This chapter provides a system overview of the
Strata CTX28 telephone system.
The Strata CTX28 system is a compact system that
provides large system features (for dimensions, see
Table 1). The CTX28 is designed for wall mounting
and occupies very little space.
The CTX28 does not require processor licenses for
Line/Station ports, DTMF Receivers, etc.
The CTX28 basic system comes with eight digital
telephone ports, three CO line ports with Caller ID
interface and one standard telephone port.
The system can be expanded to 16 digital telephone
ports, six CO line ports with Caller ID Interface and
two standard telephone interfaces.
The GCTU processor comes with a built-in
maintenance modem, one Music on Hold (MOH)
interface, one External Paging interface, one Relay
contact, and one SmartMedia card slot. The
processor is a standard part that is shipped inside
the CTX28 cabinet shipping box. The GCTU plugs
into a dedicated cabinet slot.
An optional four port voice mail circuit card (GVMU) can be added to provide Auto Attendant/
Voice Mail features including: Voice Mail Call Monitor, Voice Mail Soft keys and Record to Voice
Mail. The GVMU provides 20 hours of voice recording storage or up to 1,024 saved messages.
The GVMU plugs into a dedicated cabinet slot and requires no additional hardware to provide its
full set of features.
The plug and play CTX28 is easy and very cost effective to install. The system is pre-programmed
to match all related voice mail programming in the GVMU Voice Mail system. This includes
station numbers, mailboxes, voice mail hunt groups, voice mail station IDs and many other items
which are listed in the CTX28 Installation documentation. The pre-programmed data is set when
the processor is initialized even if the Expansion cards or GVMU Voice Mail system is not
installed prior to system initialization.

2Strata CTX General Description 10/04
The CTX28 easily connects to outside public and private telephone lines. All of the telephones
(stations) tied to the system can have direct access to each other, as well as to the public and
private network. All lines, stations, and options are tied together through the cabinet.
The table below lists the CTX28 cabinet specifications.
Digital Telephone Compatibility
The Strata CTX28 supports all
current Toshiba 2000-series and
3000-series digital telephones,
Add-on Module, DSS Console,
CTX Attendant Console, and generic
single-line telephones (2500-sets).
In addition, the Strata CTX28
supports a new Toshiba 7-button
LCD digital speakerphone model
(DKT3007-SD).
The DKT3007-SD telephone
provides the same functionality as the
10-button LCD digital speakerphone
model (DKT3010-SD), except with
fewer buttons and at a lower price.
The DKT3007-SD is designed only
for use on Strata CTX28 systems and
is not upward compatible with
CTX100 or CTX670 systems.
The Strata CTX28 does not support
analog electronic telephones (6500-series, 6000-series, etc.) or IP telephones.
CTX28 supports Handset Off-hook Call Announce (OCA), but not Speaker OCA.

Strata CTX General Description 10/04 3
CTX28 Cabinet Slots
The CTX28 Cabinet has two dedicated slots
used for the GCTU system processor card and
GVMU optional Voice Mail circuit card. All
other optional interface cards plug onto the
Processor or the Motherboard.
CTX28 Processor
Each system operates with one processor
(GCTU1A) that installs in a dedicated slot of
the Cabinet. The CTX28 processor does not
require any licenses. This includes all items
(line/station ports, DTMF receivers, ABR
circuits, etc.) The processor incorporates the
following hardware features:
CPU/Memory
The processor uses a high-speed, 32-bit, RISC
processor, Dynamic Random Access Memory
(DRAM) working memory, Static Random
Access Memory (SRAM) with lithium battery
for memory back-up, and flash program
memory.
Large Scale Integrated (LSI) Circuits (no licenses required)
The processor has an LSI circuit that supports the following:
• 16 DTMF receivers.
• 16 Busy Tone (BT) detector circuits for Auto Busy Redial (ABR).
• 64 built-in conference circuits.
• Built-in, adjustable, digital volume PAD technology enables audio volume to be adjusted in
eight steps to compensate for conference and/or CO line network losses.
GCTU Processor Interfaces
Memory Protection Battery
If commercial AC power is lost or if a system is moved or stored without power, the processor has
an on-board battery that protects data and the customer’s programmed configuration from memory
loss. This information will be maintained in a powerless system for at least six years.
Relay Control Interface
An on-board terminal strip provides an interface to a normally open relay contact which can be
programmed to control a Night Bell, door lock or to mute BGM during an external page.

Circuit Cards
Note See the “CTX28 Functional Block Diagram” on page 7 to see how the circuit cards and
interface connectors can be used for connecting stations and peripherals.
Reserve Power
One or two HPFB-6 optional units can be added to the CTX28 to provide reserve power. The
amount of reserve power time depends on the hardware (see Table 4). The table below is an
estimate of battery backup time based on the premise that the HPFB-6 unit(s) are fully changed at
the time of AC power failure. This estimated backup time is based on normal call traffic, the time
estimates will be reduced by as much as half with extreme heavy traffic volumes.
Note The CTX28 should be plugged into AC power and the DC power switch should be turned
On when installing the HPFU-6. The HPFU-6 will not start to operate if AC power is not
available during the initial installation.

Strata CTX100-S / CTX100 Overview 2
This chapter provides a system overview of the
Strata CTX100-S and CTX100 telephone
systems.
The Strata CTX100-S/CTX100 systems are
compact systems, yet they provide large system
features (see Figure 5 and Table 6). They are
designed for wall mounting and occupy very little
space.
The CTX100 processor (ACTU2A) comes with
32 ports (licensed) and can grow to 112 ports by
adding 4-port licenses.
The CTX100-S processor (ACTU2A-S) comes
with 16 ports (licensed) and can grow to 32 ports
by adding two eight-port licenses. Then, it can
grow to 112 ports with four-port licenses.
Note The Strata CTX100-S and CTX100 system capacities depend on the licenses stored on the
system processor and the hardware described in this chapter. See “CTX100-S/CTX100
License Control” on page 14.
Important! The Strata CTX100-S uses the same hardware and configuration as the Strata
CTX100, with a few exceptions. Whenever the CTX100 is mentioned in this book, it
applies to both the CTX100-S and CTX100, unless specified otherwise.
Each ACTU2 basic processor can be configured with a one or two cabinet system. A single (Base)
cabinet system supports a combination of up to 64 Central Office (CO) lines and stations, while a
two cabinet system (Base and Expansion) can support up to 112 CO lines and stations.
System line and station capacity is expanded by adding CO line and station Circuit cards and port
licenses into its universal slot architecture.
The CTX100 easily connects to outside public and private telephone lines. All of the telephones
(stations) tied to the system can have direct access to each other, as well as to the public and
private network. All lines, stations, and options are tied together through the cabinets.

CTX100-S and CTX100 Processors
12 Strata CTX General Description 10/04
CTX100-S and CTX100 Processors
Each system operates with one processor card (ACTU2A-S for CTX100-S, ACTU2A for
CTX100) that installs in a dedicated slot of the Base Cabinet. The processors incorporate the
following hardware features.
CPU/Memory
Either processor card uses a high-speed, 32-bit, RISC processor, Dynamic Random Access
Memory (DRAM) working memory, Static Random Access Memory (SRAM) with lithium battery
for memory back-up, and flash program memory.
Large Scale Integrated (LSI) Circuits
The processors each have LSI circuits that support the following:
• 16 DTMF receiver hardware processor are built into the ACTU2. Five or more DTMF
receivers requires appropriate licenses. See “CTX100-S/CTX100 License Control” on page 14.
• 16 Busy Tone (BT) detector circuits for Auto Busy Redial (ABR) are built into the ACTU2.
• 64 built-in conference circuits (see Table 12 on page 26 for more information).
• Built-in, adjustable, digital volume PAD technology enables audio volume to be adjusted in
eight steps to compensate for conference and/or CO line network losses.
Memory Protection Battery
If commercial AC power is lost or if a system is moved or stored without power, either processor
has an on-board battery that protects data and the customer’s programmed configuration from
memory loss. This information will be maintained in a powerless system for at least six years.
Relay Control Interface
An on-board terminal strip provides an interface to a normally open relay contact which can be
programmed to control a Night Bell, door lock or to mute BGM during an external page.
External Page Interface
A 600 ohm RCA jack is built into each processor to interface with a Toshiba External Amplified
Speaker (HESB) or a customer-supplied page amplifier and speaker(s) for external paging, night
ring over external page, and external BGM applications.
Music-on-hold/Background Music Interface
A 600-ohm RCA jack and volume controls are built into each processor to interface with Music-
on-hold and/or Background Music (BGM) sources (one of the jacks is for future use). With the
CTX100, you can have up to 15 MOH/BGM source interfaces by adding:
• Up to two BIOU circuit cards, each provides three MOH/BGM input sources
• An RSTU circuit card that provides up to eight MOH/BGM input sources
SmartMedia Memory
Each processor has an on-board SmartMediaTM memory card slot. A SmartMedia flash memory
card can be inserted into the slot to backup and restore customer program data. It also makes it
easy to upload operating system data for software upgrades and is used for maintenance functions
(see “System Fault Finding and Diagnostics” on page 95 for more details).

Strata CTX General Description 10/04 19
CTX670 Remote Expansion Cabinet
A CTX670 Expansion Cabinet can be located up to three kilometers (1.86 miles) from its Base
Cabinet. Remote Expansion Cabinets are enabled by the RRCU circuit card. One RRCU connects
to up to two ribbon-type Data Cables and applies the inter-cabinet signal to a multi-mode fiber-
optic pair. One fiber pair can support one or two Expansion Cabinets in one remote location using
one RRCU in the Base Cabinet and another in the Remote Expansion Cabinet.
The CTX670 Base Cabinet supports up to six Remote Expansion Cabinets (at least one RRCU
circuit card is required for each remote location).
Remote Cabinets support the BIOU for external Page Zones, Night Bell, etc., and all CO line and
trunk interface circuit cards. Network clock synchronization can only be derived from digital
trunks installed in the Base Cabinet (Master) location.
A Remote Cabinet can support all circuit cards that can be installed in a local Expansion Cabinet,
including digital trunk cards. However, the system cannot derive network clock synchronization
from a digital trunk installed in a Remote Cabinet. This requires a digital trunk installed in the
Base Cabinet or in a local Expansion Cabinet connected to the Base by a standard ribbon cable.
For each Remote Cabinet location, local trunks may be required for correct 911 service.

CTX670 Rack Mount Cabinets
The Strata CTX Rack Mount cabinets consist of a Base cabinet
(CRSUB672A) and Expansion cabinets (CRSUE672A). These
cabinets are deeper, narrower, and designed specifically to fit
standard (customer-supplied) 19” racks (shown right). The
cabinets are made of plated sheet metal, dark gray in color with
black cover plates. These cabinets support the same features as
the floor/wall-mountable CTX670 cabinets.
A CTX670 Rack Mount system can expand from one to seven
cabinets using the same processors and interface cards as the
CTX670 floor/wall-mountable cabinets. The power factors and
slot configuration rules are also the same as the floor/wall-
mountable CTX670.
The difference between the Rack Mount and the floor/wall-
mountable CTX670 is the new size for the Base and Expansion
cabinets, a new power supply that is installed in the cabinets,
and a unique power strip for Rack Mount cabinets
(BRPSB120A and the 240V version).
Toshiba does not recommend mixing the floor/wall-mountable
cabinets with the Rack Mount cabinets. The 19 inch-wide rack
and rack screws must be supplied by the dealer. Interface
cables plug into the front of the station and trunk cards and
fold under each cabinet to exit the rear of the cabinets.

Strata CTX General Description 10/04 43
IP Telephone
Toshiba offers an Internet Protocol (IP) Telephone
model, the IPT1020-SD (shown right). The BIPU-M2A
circuit card IP telephone interface must be installed in
the Strata CTX100 or CTX670 (for more details, see
“IP Telephone Features” on page 76).
The IPT1020-SD is a 20-button speakerphone model
equipped with an LCD that displays two rows of 24-

DKT3001
The DKT3001 is a Digital Single Line Telephone (shown
right). It looks similar to the other 3000-series telephone, but it
has a smaller footprint. It is narrower because there are no
flexible buttons and no LCD.
DKT3001 is not a speakerphone and does not have a Mic
button, so it does not support handsfree answerback or call
origination.
The DKT3001 connects to same digital station port as other
3000-series digital telephones. This makes it compatible with
all Strata CTX and Strata DK systems.
Features
The DKT3001 supports many features of the other 3000-series digital telephones, including:
• On-hook dialing
• Headset/Loud Ringer Interface (BHEU)
• Line button with a red LED. The Line button for the DKT3001 is the [PDN] on this telephone.

or 2000-series telephone, IPT1020-SD or DSS console.
The BSTA tilt stands support 3000-series digital telephones and
IPT telephones with one or two Add-on modules. Both types of
tilt stands can adjust to four different angles.
Telephone Upgrade Options
Upgrade options for the Toshiba 3000-series digital telephones
and IP telephones are described below.
Digital Add-on Modules
(DADM3120, DADM3020)
The DADM3120 adds 20 feature buttons to the
IPT1020-SD or the DKT3000-series telephones.
The DADM3020 (shown right) adds 20 feature
buttons to DKT3000-series telephones only.
Both the DADM3120 and the DADM3020 provide
the same functions, but they are not interchangeable.
Both the DADM3120 and the DADM3020 have 20
flexible feature buttons that can be assigned as CO
line, Directory Number, DSS, One Touch Speed Dial
or any other flexible feature.
Add-on modules connect directly to the telephones
and do not require an additional interface circuit
(port).

Direct Station Selection (DSS) Console
The DDSS3060 console (shown right) is for system
attendants.
The DDSS3060 operates alongside a digital telephone and
have 60 flexible feature buttons. These flexible feature
buttons can be assigned as CO line, Directory Number, DSS,
One Touch Speed Dial or any other flexible feature. The
DDSS3060 is not compatible with the IPT1020-SD.
Up to eight consoles can operate with one digital telephone;
16 consoles max. per system.
The DDSS3060 console uses LEDs to indicate call and
feature status; the DDSS has dual red and green LEDs to
help further define status, such as station in DND status. The
DDSS3060 console connects to a digital station port on the
ADKU, BDKU, BDKS or PDKU card.
Integrated PC Interface (BPCI)
An optional BPCI can be installed inside any 3000-series telephone to provide a USB connection
to a PC with Microsoft® Windows® Telephony Application Programming Interface (TAPI)
applications.
Information such as ANI, DNIS, and Caller ID data is sent from the digital telephone/BPCI to a
computer to provide information for “pop-up” screens. The Telephone Service Provider Interface
(TSPI) PC software is included with each BPCI.
The BPCI also enables simultaneous Computer Telephone Integration (CTI) and voice features,
without the need of a modem or an extra outgoing line.
The PC Interface (BPCI) cannot be installed in digital phones shared with the Cordless DKT-2004-
CT telephone, DKT3001 single line telephones, or telephones that have Speaker OCA Interface
(BVSU) or Add-on modules.
Headset/Ringer Interface (BHEU)
The BHEU provides interfaces for both a headset and a loud ringing speaker for DKT3000-series
telephones. The optionally used amplifier in the BHEU enables users to adjust the headset volume
with the volume button on their telephone.
With the loud amplified speaker feature, the speaker amplifies the ringing or voice announcement
of an incoming call. The HESB speaker box is required for the loud ringing speaker and is
normally mounted on a wall near the telephone.
BHEU can be installed in the same telephone that has BPCI or BVSU modules installed.
The BHEU is not required on the IPT1020-SD telephone which has a built-in headset interface.
Speaker Off-hook Call Announce (BVSU)
BVSU-equipped digital telephones can receive Speaker OCA which enables stations to receive
internal calls over their speaker while on another call using the handset. The BVSU is not required
in a telephone to originate OCA calls or in a digital telephone that receives OCA calls through the
handset or headset.
Speaker OCA Interface (BVSU) cannot be installed in DKT3001 telephones or in telephones with
a PC Interface (BPCI). The BVSU cannot be installed in the IPT1020-SD telephones. IPT1020-
SDs do not support Speaker OCA, but they do support Handset OCA.

Cordless Digital Telephones
Toshiba offers two cordless digital telephone models, the DKT2204-CT and the DKT2304-CT
(see photos in this section). These compact cordless digital telephones bring mobility and
productivity to office telephones. Greater call access cuts down on leaving messages and playing
“telephone tag.”
The DKT2204-CT and DKT2304-CT telephones operate from the same digital station port as the
DKT3000-series digital telephone. They cannot receive Group Pages or All Call Pages. They can
be attached to a Toshiba DKT3000- or 2000-series corded digital telephone or used as a stand-
alone. If a cordless telephone is attached to a DKT3000, the DKT3000 must be put into 2000-
mode.
Some of the features for both cordless models include:
•Liquid Crystal Display (LCD) that wraps using two lines, total of 32 characters
•Ringer and handset volume control
•Single button access to: Conference, Hold, Redial, Message and Transfer features
•Four programmable function buttons

CTX Attendant Console
48 Strata CTX General Description 10/04
CTX Attendant Console
The Strata CTX Attendant Console runs on a PC with Microsoft® Windows® 2000 Professional
operating system. The Strata CTX Attendant Console PC is equipped with an Intel two gigahertz
CPU in a small, compact desktop chassis that is just the right size for a receptionist’s desk. If there
isn’t any room on the desk for the system to lay flat, it can also be stood on its side for an even
smaller footprint. Add to that the powerful Strata CTX Attendant Console software, and you have
a winning solution for any Strata CTX installation!
The Console connects to the Strata CTX processor via the LAN as a Customer Supported
Telephony Application (CSTA). The Strata CTX system requires the processor NIC interface
subassembly. This is standard on CTX670 and is optional on CTX100 (AETS1A) and CTX28
(GETS1A). It also connects to a digital telephone port for the speech path.
The Attendant Console (CTX-ATTCONSOLE2) consists of the following standard items:
• Attendant Console License for the CTX processor
• Intel 2 GHz CPU
• 256M Random Access Memory (RAM)
•CD R/W drive
• Windows 2000 Professional (factory installed)
• CTX Attendant Console software (factory installed)
• Comprehensive set of multimedia inputs and outputs
• Keyboard & Mouse
The optional items are:
• Special Attendant Keyboard stickers (CTX-KL-ATCON-VA)
• 17” Flat screen Monitor – Toshiba offers a 17” Liquid Crystal Display (LCD) flat screen
monitor; part number CTX-LCD-MONITOR.
• Attendant Console Interface Unit (BATI) and Handset/Cradle (BATHC) connects to a digital
telephone interface port on the Strata CTX. An optional headset can be used in conjunction
with the handset.
...or
a DKT3001 can be used as the console handset. If an optional headset is used, it connects to the
optional BHEU installed in the DKT3001.
Important!
•If a digital telephone is used in place of the BATI/Handset, it can be used as the Attendant
Console Handset only. It cannot be used as a telephone to make or receive calls independent of
the console. This includes when the console is in service or out of service.
The Strata CTX670 system supports up to four, and the CTX28 and CTX100 supports up to two
Attendant Consoles. Multiple consoles automatically share the incoming call load on a call-by-call
rotation basis. Features such as Overflow, Position Busy, and Interposition Call Transfer add to the
efficiency of single or multiple console applications.
Telephones and Peripherals
CTX Attendant Console
Strata CTX General Description 10/04 49
The CTX Attendant Console is designed to handle all call activity within a single Call Monitor
screen, shown below. All calls will appear in a single list.
Calls are marked with icons to show the current status.
Features such as Paging, Call Pickup, Call Park offer many alternatives. The Administration
window enables which option is the primary operation for that Attendant. For example, if two
zones are used for paging, as well as the All Call, then an option pull down arrow is next to the
icon. Clicking the icon starts the All Call Page, then the Attendant can select one of two page
zones.
All other views available for the Attendant are for administrative and management use. They do
not control any type of call handling except how chosen options affect the overall operation.
The CTX Attendant Console also enables an attendant to manage console settings, maintain a user
directory, and view call statistics. The Console provides a Name/Number search that works with
automatic or manual call handling. Other features include Queuing, DSS, signaling, Emergency
Call ID, keyboard or mouse operation, and headset or handset operation with volume control.

as door phones for visitor screening, a music source interface for MOH and ACD queues, a
speaker for amplified ringer, Toshiba Voice Processing systems for voice mail/auto attendant
applications, and more.
Toshiba Digital Solutions Division (DSD) does not provide ISDN or IP station equipment, such as
ISDN IP telephones, fax machines, and computer interface devices for high speed Internet access
or video conferencing. Toshiba does provide the interface circuit boards that support all of the
above ISDN station equipment.
MCK Office Extender and PBX Gateway
The MCK Office Extender enables groups of remote workers to have cost-effective, digital line
extensions off the main location’s Strata CTX system and voice mail system, without the cost or
administrative difficulty of installing a separate system. The Extender offers the following:
• Supports up to one, eight or 12 or 24 users per stackable unit.
• Fully-featured Toshiba digital telephones with Strata CTX system features and ACD.
• Choice of network protocol support and compression rates minimizes communications cost.
• Corporate or remote management tools provide flexible administration.
• Dual Wide Area Network (WAN) interfaces allow multiple network options like T1, Frame,
Digital Data Systems (DDS), Integrated Services Digital Network (ISDN), Digital Subscriber
Line (DSL), cable, etc.
Door Phone (MDFB)
Door phones can be assigned to ring telephones when the button on the door
phone is pressed. The Door Phone location displays on the called telephone’s
LCD. When the telephone answers, a two-way talk path exists between the
telephone and door phone.
Door phones can also be used as sound monitors. Station users can call the
door phone (it will not ring) and listen to sounds from the surrounding area.
Door phones also can operate as a “hot line.” For example, a door phone can
be used for calls between an office and a warehouse. Door Phones are often
used with a door lock to screen building visitors. The door lock can be opened
for a predetermined amount of time by pressing a button on a telephone.

Door Phone/Lock Control Unit (DDCB)
The DDCB can support as many as three door phones (MDFBs)
or two door phones (MDFBs) and one door lock control relay.
Using the door lock control, digital station users can unlock a
customer-supplied electronic door lock at the touch of a button
programmed on their digital telephone or by dialing a feature
access code from any type of telephone. Each DDCB requires
one digital station circuit.
Each door lock can be programmed to remain open between
three~30 seconds. The Door Lock button LED remains On while
the lock is open. LCD telephones display “DOOR
UNLOCKED” until the telephone releases or times out.
External Speaker (HESB)
The HESB is a multi-functional, external, six-inch speaker unit with a built-in three-watt amplifier.
It can be used as a paging speaker, an amplified talkback speaker, or a telephone’s Loud Ringer.
Toshiba Stratagy and Stratagy DK Voice Processing
The Strata CTX can operate with Toshiba Stratagy and Stratagy DK voice processing systems,
which provide a number of helpful features. The Strata CTX supports in-band DTMF voice mail
integration for all of the above voice mail systems and requires DTMF receivers. It also supports
standard SMDI and Toshiba Proprietary voice mail integration. Refer to the appropriate Stratagy
literature for details.
Cabling and Connectors
The Strata CTX uses industry standard cabling and connectors to interface with lines, stations, and
peripherals. Stations use standard twisted-pair cabling to connect to the system via the MDF.
Digital and standard telephones require just one pair-cabling. Two pairs may be required to
achieve full distance when optional DKT subassemblies are used.
Digital telephones connected to BDKS require an external power supply to reach maximum
distance from KSU when the telephone has a DADM, BPCI or BVSU.
Station circuit cards connect to stations and peripherals with a 25-pair Amphenol connector via the
MDF. Analog CO, DID, and Tie line circuits interface with the public telephone network via
modular connectors. T1 and ISDN use industry-standard Amphenol and modular connectors (for
details, see Table 34 on page 107).
Peripheral devices such as CTX WinAdmin maintenance PCs, etc., connect to a hub or LAN,
which connects to the processor’s Ethernet LAN interface via an RJ45 connector and Category 5
wiring. Call Accounting and Voice Mail SMDI require RS-232 modular adapters and cords to
connect to the processor BSIS interface.

Features 7
This chapter contains the Strata CTX100 and CTX670 features. They are presented in alphabetical
order to make it easy to locate each feature.
Account Codes
System Availability: All systems
Account Codes are often used for cost allocation of the call or the time the caller was involved on
a phone call. The codes are printed on a Station Message Detail Recording (SMDR) printout along
with other call details so that the customer can identify all calls associated with a specific account
code.
Account codes may be forced (required after dialing all or specific phone numbers) or voluntary
(optionally entered anytime during calls). Codes can be as long as 15 digits and can be verified or
non-verified by the system. An account code button can be programmed on a digital telephone to
make voluntary account code entry convenient and easy.
Add-on Module (DADM)
System Availability: All systems
One to two DADM3020s or DADM3120s can be attached to a DKT3000-series digital telephone
to provide an additional 20 or 40 flexible buttons. DADM3020 and DADM3120 buttons can be
programmed with outside line or Directory Number buttons, Direct Station Selection, One Touch
Speed Dial or any other flexible feature button. For more information, see “Digital Add-on
Modules (DADM3120, DADM3020)” on page 44.
Advisory Messages
System Availability: All systems
Any telephone user can set a message on his or her telephone. Whenever another station with a
display calls a station with a message set, the information in the message displays on the calling
station’s LCD. This feature allows users to define their current status and make that status
available to others attempting to call that person. This status is also sent to Attendant Console
positions.
Features
Alternate Answer Point
54 Strata CTX General Description 10/04
Alternate Answer Point
System Availability: All systems
Users can answer a transferred internal or outside line call from any station that has a Directory
Number button appearance of the “transferred to” Directory Number.
Automatic Busy Redial
System Availability: All systems
Automatic Busy Redial (ABR) enables a digital or standard telephone user to automatically redial
a busy outside number multiple times at programmed intervals. Strata CTX supports a maximum
of 16 or 32 simultaneous registrations of ABR (limited by the number of busy tone detectors in the
system). Each station may only have at most one call registered with ABR at any time.
Automatic Call Distribution (ACD) Server
System Availability: All systems
An external ACD software option with the Strata CTX provided by connection of an external PC-
based CTI application server. The CTI server will run both the ACD call processing application
and the separate Management Information System (MIS) application such as Insight CTX, as well
as other CTI applications.
The ACD application will be available in Basic and Enhanced feature functionality, along with the
number of groups and active agent size increments to provide cost-effective pricing levels
according to the user’s needs. Enhanced ACD includes all basic capabilities plus multiple group
login, skills-based routing, priority queuing, time scheduled ACD queues, agent and call priority
escalation handling, and balanced call count agent search. For more information, refer to the Strata
ACD General Description, or the Strata ACD Application Software and Documentation Library or
OAISYS CD-ROMs.
Basic ACD Features
Advanced Call Routing
The optional Call Router enables calls to be routed based upon parameters such as Caller ID,
Account Numbers, private lists, time-of-day, day-of-week, day-of-year, and user entered data
(account code, etc.). This is an optional feature that can be added to the ACD application.
Intelligent Announcements
The holding caller can be informed of call status, such as their place in queue or estimated time
before an agent answers. The intelligent announcement function can also offer alternative options
to continuing to hold, such as going to voice mail.
IVR Voice Assistant Open Database Connectivity (ODBC) Access
There are two options that can be used with customized services: Interactive Voice Response
(IVR) Voice Assistant (VA) application can be used as a stand-alone product and/or as an IVR
service to the ACD application. For example, an IVR port could be used to do an external page to
alert agents to return and login to an ACD queue when it gets too overloaded with calls.
Other useful functions include gather and validate user input, play menus and act on response, and
trigger other events. The IVR VA can also be used to provide low cost text to speech capabilities.
The IVR VA is an optional feature that can be added to the ACD application.
Features
Automatic Callback (ACB)
Strata CTX General Description 10/04 55
Enhanced ACD Features
Agent Priority Routing
The Agent pool can be expanded when traffic gets heavy based upon agent priority levels. When
all agents are busy at one level, calls automatically get distributed to agents at the next level. Calls
can be distributed by agent priority, preferred agent treatment, or balanced call count.
Multiple Group Agent Login
ACD agents can be logged into multiple ACD groups, enabling agents to answer calls for multiple
groups. This is very useful for back up coverage between groups. It is also the foundation for
skills-based routing and agent priority routing, enabling many advanced call center applications.
Skills-based Routing
Based on the caller’s input, the system can route the call to the agent best suited to handle the call.
Calls can be routed to certain agents, based upon agent capabilities, in addition to Dialed Number
Identification Service (DNIS), CO line, or Auto Attendant routing into different groups. With the
capability for agents to log into multiple groups, calls can be routed to different agents based upon
skills needed for each specific call.
Priority Queuing
ACD calls can optionally be tagged with a priority number before they are placed into the ACD
group queue. The priority number assigned to the call determines where the call is placed in queue.
This feature enables high priority calls to be answered sooner than low-priority calls. The
escalation parameter ensures that no call is lost by higher priority calls.
Automatic Callback (ACB)
System Availability: All systems
When a station user dials a busy station [DN] or outside line access code and receives busy tone,
ACB can be activated by pressing an ACB feature Soft Key or by dialing 4. When the busy [DN]
or outside line becomes available, the station will be automatically called back and be connected to
and ring the originally called station or receive dial tone from an outgoing line.
When ACB is activated, the calling station receives success tone followed by busy tone. Once
ACB is activated, the caller can hang up. ACB can be canceled any time using an access code. It
will also cancel automatically after a predetermined time.
Automatic Line Selection
System Availability: All systems
This feature automatically connects a telephone to a specific line or extension button when the user
lifts the handset off-hook, presses the Spkr (speaker) button, or presses a digit on the dial pad (Hot
Dialing). This feature is necessary to make telephone operation consistent for the user because a
telephone can have up to 20 line and extension buttons. Each telephone can be assigned in system
programming with various options that determine what type of line or extension button is selected
when the user takes the handset off-hook to make or answer calls.
When answering calls, this option can be set to answer the call or not when a call rings the
telephone and the user takes the handset off-hook. If the option is set to not answer automatically,
the user can press the ringing button on the telephone to answer manually. With Automatic line
selection, if more than one type of call is ringing simultaneously on the telephone, this option
selects which type of call will be answered as a priority, then the longest ringing call in that call
type will be answered first.
Automatic line selection options are set independently for each telephone, for originating new
calls and answering ringing calls. This feature can also be disabled on all or selected telephones to
allow users to manually press a button to originate or answer calls.
Features
Automatic Release
56 Strata CTX General Description 10/04
Automatic Release
System Availability: All systems
The system will automatically release line connections under certain conditions.
Automatic Release from Hold
When a line is on hold and the held party hangs up, the line is automatically released. Individual
loop start CO lines can be programmed to detect disconnect supervision signals from the CO and
to respond by releasing the line. If the CO does not provide Disconnect Supervision, the user must
manually retrieve the held line and then hang up.
Automatic Release of Incoming Calls
An outside caller may be placed in a queue waiting for an external application to handle the call
such as an Auto Attendant, IVR, ACD or other device. If the CO line for that call does not offer
“disconnect supervision,” that call may remain in a holding position until forced to release the
connection.
This feature provides full use of all CO lines at all times. A CO line is not tied up if the call goes
unanswered and no alternative call handling is provided. This is very useful for disconnect
supervision in voice mail and built-in auto attendant applications, but availability and reliability of
the signaling from the CO must be confirmed.
Station Automatic Release
When the distant party disconnects from a call, the remaining digital telephone is automatically
made idle, busy tone is not sent to the speakerphone or handset, and the digital telephone is
automatically released. A digital telephone is released and returned to idle state. A standard
telephone is simply released and returned to standard dial tone. The programming choice for this
feature is system wide.
Background Music (BGM)
System Availability: All systems
Background music audio can be played through the speakers of digital telephones and external
paging equipment. The Strata CTX supports up to 15 BGM audio input interfaces. Selection of
which BGM source is played can be done individually by each telephone user and for each
external page zone through the System Administrator’s telephone.
Call Completion
System Availability: All systems
When calls are not completed because the station does not answer, is busy, or is in Do Not Disturb.
A series of options are available to the user when encountering these conditions. They include
changing the calling signal from Voice Announce to Ringing or vice versa, setting Automatic
Callback, setting the Message Waiting light, Camp on Busy, Overriding the condition with
Privacy/DND/Executive Overrides, or using Off-Hook Call Announce.
These options are easily activated by dialing a single digit code or pressing a soft key when the
condition is recognized. These options are individually set for each telephone to be able to activate
the call completion feature and separately to permit the feature to be activated when called.
Features
Call Forward
Strata CTX General Description 10/04 57
Call Forward
System Availability: All systems
Call Forward diverts internal and external calls intended for a Directory Number [DN] to a
destination specified for that [DN], under calling conditions specified for that [DN]. Call Forward
may be activated from the station that owns the [DN] or remotely from another station or from
outside the system from a DISA line. Call Forward may be applied to any [DN] ([PDN], [PhDN],
or Pilot [DN]).
There are two types of Call Forward options: System Call Forward and Station Call Forward. Each
type may be activated independently or simultaneously for each telephone. If Station CF is
activated, it will override System Call Forward on some or all calls.
Station Call Forward
Station users can set their individual call forwarding conditions and destinations as they choose
(see “Call Forward Conditions” and “Call Forward Destination” in this section). Station
forwarding has priority over System Call Forwarding, if set.
Station Call Forward provides two types of Call Forward (Any Call and Incoming line calls only).
One type directs any type of a call to a designated destination; the other type directs only private or
DID lines to a designated destination. Both types can be set on a telephone simultaneously with
each type having a unique destination.
This allows the user to forward incoming calls on private or DID lines to a different destination
than internal or transferred calls. If private and DID line calls are set to forward independently to
an alternate destination, then internal and transferred calls will forward to another destination per
Station Call Forward (any call) or System Call Forward.
System Call Forward
A system option is available to forward unanswered calls to voice mail or some other pre-
determined destination. This option is set up for each station by the System Administrator using
CTX WinAdmin. This feature is applied to station users that do not have any type of Station Call
Forward set on their telephone. This ensures efficient call handling and better service to callers
even when station users do not have Station Call Forward set at their telephone. Call Forwarding
can also be set up by department with a special mailbox or destination with the use of Phantom
Directory Numbers [PhDNs].
There are 32 different System Call Forward patterns that can flexibly forward calls with unique
call type, condition and destination settings. Each pattern can be set up and assigned to individual
stations by a System Administrator using CTX WinAdmin. Any pattern can be applied
independently to each station’s [PDN] or [PhDN]. System Call Forward patterns applied to
stations can be changed automatically per Day/Night CO assignments.
Although System Call Forward is set up and assigned to individual telephones by a System
Administrator, each telephone user can turn the feature On/Off from their telephone using a One
Touch button or access code. Station Call Forwarding always overrides System Call Forward.
With Release 1.3 and higher, you can enable/disable System Call Forward Cascade, which means
that a call that forwards to a destination that is also forwarded will follow the destination’s call
forward.
Features
Call Forward
58 Strata CTX General Description 10/04
Call Forward Conditions
Call Forward (CF) conditions refer to the status of the [DN] that causes a call to forward. Whether
using Station or System Call Forward, the CF conditions include: Busy, No Answer, Busy-No
Answer, and All Calls (station CF only). Call Forward No Answer times are set individually for
each station in Station Call Forward and system wide for all System Call Forward Patterns.
Note OCA and Voice First Calls will not Call Forward-No Answer unless the caller presses 1 to
switch the call to tone ringing.
Call Forward Destination
Whether using Station or System Call Forward, the CF destination can be an internal Directory
Number, a Hunt or ACD Group, Voice Mail, or a public or private network telephone number.
In the last case, the forwarded call will access an outside line or line group and dial an external
telephone number. Both the line access code and the telephone number are set in the Call Forward
destination during the Call Forward setup operation.
Station Call Forward allows one destination per each type of Station Call Forward (Any Call or
Incoming Line Calls) set on a telephone. System Call Forward allows two destinations per Call
Forward pattern: the Primary Destination and an alternate, in case a call cannot forward to the
Primary Destination (e.g., the Primary Destination has been unplugged or malfunctions).
Call Forward – Call Types
In each System Call Forward pattern, the Call Forward conditions and destinations can be set
independently.
For Station Call Forward, the destination and condition for each station can be different for
incoming CO line calls, and internal and transferred calls.
Call Forward Remote
A station’s personal call forwarding destination can be cancelled or changed to another outside
number or an internal voice mailbox either remotely via DISA or from another user’s telephone.
Changing Call Forward remotely is password protected. System Call Forward can be changed
locally or remotely using CTX WinAdmin.
Call Forward Override
See “Call Forward Override” on page 88.
Features
Call History
Strata CTX General Description 10/04 59
Call History
System Availability: All systems
Incoming calls with Caller ID or ANI information may be optionally recorded into a rolling list for
the station where the call is ringing. The call is placed in the list along with the number, name (if
provided), time and date of the call, and status of the call (answered, abandoned, or redirected).
This list is accessible by the user from the telephone LCD and any call may be selected and
redialed using the flexible Caller ID button.
When calls ring a button (Line or [DN]) that appears on multiple stations, the number is stored on
the telephone that is designated as the owner of the Line or [DN] and on the telephone that
answers the call. If an incoming call is directed to a telephone, but the call is not answered by that
telephone because it hunts or forwards to another destination, the call record will still be stored on
that telephone as “redirected” and on the telephone that answers the call as “answered.” If a call is
not answered, it is stored on the line or [DN] owner’s telephone as “abandoned.”
To store call records, a telephone must be allocated Call History memory by the System
Administrator. The number of call records allowed per station and the total number of call records
per system is provided in Table 12 on page 26.
Call Park
System Availability: All systems
Call Park gives any station, regardless of type, a method for holding calls. By parking a call, you
are free to make other calls and retrieve the call at a later time or use the paging system to
announce a call to be picked up by someone else on the system. Any call can be parked. Parking a
call to your phone is known as Local Park, parking a call on someone else’s phone is known as
Remote Park, and if a general orbit is used, it called Auto Park.
Call Park Orbits
The Call Park feature enables a station user to place a call temporarily in an orbit so that the call
can be retrieved by any user, either from the same station or from a different station. Personal Park
Orbits are available to any type of telephone, including standard telephones. If a call is parked, but
not retrieved within a preprogrammed time period, it will recall the parking telephone. The Park
recall time is set individually for each station.
Refer to Table 12 on page 26 for the number of General Park and Personal Park Orbits, depending
on the system processor.
Park and Page
This feature enables station users to park a call (in a General or Personal Park Orbit), enter a Page
Zone or Group access code, and then announce the orbit number of the waiting call to the Paged
party. A pre-programmed One Touch button can be assigned to telephones to automatically
connect to a predesignated External Paging circuit, a Telephone Paging group or both.
Features
Call Pickup
60 Strata CTX General Description 10/04
Call Pickup
System Availability: All systems
Call Pickup enables station users to pick up all types of ringing or held calls including internal,
[PDN] or [PhDN] calls ringing or on hold at other stations. Station users can also pick up CO/DID/
Tie line calls ringing or on hold at other stations, CO lines ringing during Night Mode to External
Page or night bell, tandem CO line connections and Door Phone calls. Call pickup can be
performed through programmable buttons (Directed Pickup, Group Pickup), or with an access
code.
Call Waiting
System Availability: All systems
When a station is busy with a call and another call is directed to that station’s busy Line or [DN]
button, two short beeps are issued to alert the telephone user of the pending call. To answer the
Call Waiting, the user must transfer or disconnect the existing call.
Call Waiting works for calls originating from within or outside the system. The length of the Call
Waiting beeps is different for internal and external Call Waiting. The different beeps distinguish
which type of call is waiting.
Caller ID DNIS or ANI information appears on LCD telephones for 10 seconds. If Caller ID
information is not available, the device name, such as the CO line or DNIS name or number is
shown.
Digital telephones can be adjusted to receive or not receive Call Waiting tone over the handset or
headset receiver, as well as the speaker. Standard telephones will receive Call Waiting tone twice
from the handset receiver. Call Waiting tones can also be turned off on each station by a System
Administrator.
When a station is busy with a call and another call is being received, a tone alerts the caller of a
pending call. On LCD telephones, the Caller ID information displays for 10 seconds. The
combined effect of the Call Waiting alert tone with the displayed information enables users to
identify whether or not they want to interrupt their current call for the waiting call.
To answer the Call Waiting, the current call must be put on hold, terminated or transferred.
Multiple calls can be queued to a single station, all waiting for that station to become free; the call
at the head of the queue provides the Call Waiting signal and LCD indication.
This feature works with both digital and analog single-line telephones. The tone (two beeps)
signaling Call Waiting tone is provided through the speaker of the digital phone. For standard
analog telephones, the tone is inserted into the speech path. Caller ID display is not available with
standard telephones.
Features
Caller Identification
Strata CTX General Description 10/04 61
Caller Identification
Caller Identification (Caller ID) is the general term for the information provided identifying the
originating party of a public network call. The name and telephone number of the calling party
displays on the ringing telephone’s LCD. Incoming calls with Caller ID or Automatic Number
Identification (ANI) information may be optionally recorded into a rolling list for individual
stations. Station users with LCD displays can access this list to select and redial these calls (see
Call History). Caller ID service from the carrier must be subscribed on analog CO lines or T1 ANI
in order to receive calling number and name into the Strata CTX system.
Caller ID lists can include the number, name (if provided), time and date of the call, and status of
the call (answered, abandoned, or redirected). Digital stations are assigned memory for creating
the Call History. See Table 12 on page 26 for the number of call records per station and system.
ISDN Calling ID Name and Number
System Availability: Strata CTX100, CTX670
Both Caller ID name, if available from service provider, and number are supported for incoming
calls using either ISDN NI-1 or NI-2 BRI or PRI lines. Caller ID names can be accepted by the
Strata CTX from a CO with NI-1 or NI-2. NI-2 is the only way a 5ESS CO delivers Caller ID
names on PRI and BRI. Nortel DMS CO with NI-2 installed also uses NI-2 to deliver Caller ID
names. Only a Nortel DMS CO can provide Calling Names for NI-1.
Camp on Busy
System Availability: All systems
Automatic Camp On
When a call comes in to a busy station from an outside line and that station does not have an idle
button for the call to ring in on, and Station Hunting or Call Forward is not applied, the call
automatically camps on to the busy station. This permits incoming calls to be accepted even if the
station is busy. The outside caller will receive ring-back-tone immediately and the called station
will receive two bursts of Call Waiting tone.
If the calling line has Caller ID, ANI, or DNIS information, it will be displayed on the called
station’s LCD for 10 seconds. Auto Camp On also applies to incoming line calls directed to Hunt
Groups, Voice Mail systems, etc.
Various types of internal calls from one station to a busy station, voice mail system or hunt group
can also Camp On automatically with system programming options. For details on these types of
calls see the Camp On-Busy and Station Hunting descriptions.
Off-hook Camp On
A station caller who dials a busy station or line access code can remain off-hook to be
automatically connected when the station or line becomes idle. After dialing a busy [DN] and
receiving busy tone, the caller can just remain off-hook and Camp On will be initiated
automatically after a predetermined time or the user can dial a 1 and remain off-hook to initiate
Camp On immediately. When camp-on is activated, the caller will receive success tone followed
by Ring Back Tone. The station that is the object of a camped-on call will receive two bursts of
call waiting tone (see Call Waiting).
Features
Cancel Button
62 Strata CTX General Description 10/04
Even if Voice First is set at the called [DN], the station will be called by tone ringing when it is
connected by Camp On. Internal and external stations can be the object of a Camp On. Calls may
be camped on to the pilot number of Station Hunting groups and will be delivered to the first
station in the group to become idle. ACD pilot numbers cannot be the object of a Camp On.
Incoming calls from outside lines to busy DNs camp-on automatically (see “Automatic Camp
On,” previous section). When a station dials the access code for an outside line and receives busy
tone because all lines are busy, the user can remain off-hook and dial 1 to camp on to the busy line
group. When a line becomes available, the station will connect to the line and receive dial tone.
When more than one party is camped on (queued) to a destination, the party with the highest
Queuing Priority Level (QPL) will be connected first when the destination becomes available. If
the parties have the same QPL, the longest waiting call will be connected first.
Calls will camp on to hunt groups when all members of the group are busy (see “Station Hunting”
on page 92 for more details).
Cancel Button
System Availability: All systems
The Cancel button voids the last entry or step in a procedure. This enables the station user to
correct an error and then continue without having to starting over.
It is important to consider the consequences of this button in regards to the overall task. For
example, during a conference call, Cancel will disconnect the last party added to the conference.
Centrex/PBX Compatible
System Availability: All systems
All system features are compatible with Centrex/PBX operation, including repeat of Centrex/PBX
ringing cadence, one-button access to Centrex/PBX features, a two- to five-digit station numbering
plan, and Delayed Ringing to selected stations.
Centrex Ringing Repeat
System Availability: All systems
The system can mimic CO/Centrex/PBX ringing cadences received from outside lines when it
rings a called station.
Classes of Service (COS)
System Availability: All systems
Classes of Service are the mechanisms for assigning features and services to lines and stations
within the system. The Class of Service for a given device, such as a station, is defined using 38
parameters. There are 32 Class of Service patterns available, each pattern can be set up to allow a
unique combination of features. Each station and line group can be assigned independently to one
of the 32 COS patterns.
Features
Computer Telephony Integration (CTI)
Strata CTX General Description 10/04 63
Computer Telephony Integration (CTI)
System Availability: All systems
CTI combines the capabilities of the Strata CTX digital business telephone system with custom
functionality provided by computer applications. This can be provided through the optional Digital
Telephone Integrated PC Interface or a system connection using the LAN connection.
Digital Telephone Integrated PC Interface
For CTI applications, digital telephones interface to a PC that runs the application software using
the Microsoft Telephone Application Programming Interface (TAPI), to provide customized
functionality. The PC must run Microsoft Windows software.
Any TAPI-enabled PC software is compatible with Strata CTX systems. The most common types
of application are database look-up and pop-up screens that provide information on the calling
party. From a Strata CTX system, Caller ID, ANI, DNIS and call processing information can be
passed from the digital telephone to the application computer.
The 3000-series digital telephone uses an integrated PC Interface Unit (BPCI) for TAPI and data
switching simultaneous voice/data applications. The 3000-series digital telephone must be
connected to the system through a BDKU digital station card. The BPCI provides a highly
functional interface for fast, positive call control via a USB port and supports media streaming
with TAPI 2.0 functionality.
Conference Calls
System Availability: All systems
Conference calling enables other people to join your conversation. These additional people can be
inside or outside the Strata CTX system. Any station can set up a conference with other stations or
outside lines. A conference is defined as any time three or more parties join into one conversation.
A maximum of eight parties are allowed into a conference with up to six from outside lines or
standard stations. The originator of the first conference is the “master” and controls adding and
deleting conference parties. The conference “master” can drop off the last added party by using the
Cancel button.
Conference On-Hold
A conference call may be put on Hold so that all the remaining conferees remain connected and no
Music-on-hold is applied. The person putting the conference on hold may rejoin the conference by
pressing the Line button on his phone. The Hold state of the conference can be released from
another station by pressing the Line button of that station. At this time, the station that released
the Hold state becomes Conference Master. This enables one person to establish a conference call
for others.
Join Button
Join allows an attendant or digital station user to connect two established calls to each other.

This feature enables the conference master to add (Join) other phones to a conference. The
conference master and another member of the conference can leave (Split) the conference for a
private conversation. During this time, other conference members remain connected. The
conference master can then Join both of the Split callers back into the conference, or the master
can Drop (disconnect) the Split member he/she is connected to. This feature requires an LCD
phone with Soft Keys. A flexible Split button can be added to a 3000- or 2000-series telephone to
use this feature.
Releasing from Conference Tandem CO Line Connections
This feature enables unattended line-to-line connections for the Strata CTX, freeing the
conferencing analog station or voice mail port for other calls and important tasks. When a tandem
connection is set up with a [DN] button, the [DN] button will go idle after releasing from the
connection. The [DN] can then be used to make or receive calls from the originating digital
telephone.
Standard telephones and/or VM devices can establish tandem analog CO line connections and then
release from them without disconnecting the tandem connection in the Strata CTX. After releasing
from a tandem call, reconnecting to the call can be accomplished by dialing an access code. This
reconnect feature does not work if one or both of the CO lines are digital.
Whether or not tandem line buttons appear on a telephone, the telephone user can enter the
connection and release the line that was connected to the original line or release both lines by
pressing the Cancel button. For details on 2-B channel release from conference transfer, see
“Integrated Services Digital Network (ISDN)” on page 84.
Voice Mail Conference
Voice Mail ports may be included in conference calls. This enables all members of the conference
to listen to and play voice mail messages.
Continuous DTMF Tone
System Availability: All systems
Dual-Tone Multi-Frequency (DTMF) dial signal is transmitted to the CO line or voice mail/Auto
Attendant device for as long as the telephone user presses a button on the dial pad. This feature
may be selected for each digital telephone. Standard telephones always provide continuous DTMF
tone operation.
Credit Card Calling
System Availability: All systems
Callers can make “0+” telephone credit card calls from selected toll restricted stations. When
dialing from toll restricted stations, if the caller does not enter a credit card number after dialing
“0,” the call will be disconnected. Calls are billed to the credit card instead of the Strata CTX CO
line. The “0+” credit card calling feature can be enabled, selectively, or assigned to stations and
CO lines capable of supporting this service.
Features
CTX WinAdmin
Strata CTX General Description 10/04 65
CTX WinAdmin
System Availability: All systems
CTX WinAdmin is the Strata CTX administration software application for programming and
maintaining the system. It operates with Microsoft Windows 2000 Professional® and Windows
XP Professional, with Windows Explorer 6.0 or higher. It has a user-friendly GUI and provides
access levels for technicians and end-user administrators.
Strata CTX WinAdmin connects to the system processor’s network jack or maintenance modem
(33.6Kpbs/V.34) modem. Direct wire connection, LAN connection or remote connection over the
Internet or PSTN is also available.
Data Privacy
System Availability: All systems
This option blocks calls to data devices that are in use. This prevents override calls and warning
tones from interfering with data devices such as modems and ISDN data terminals.
Day/Night Mode – Auto Schedule
System Availability: All systems
The system has three operating modes that are based on the time-of-day, day-of-the-week, and up
to 128 holiday schedules. The operating modes are Day, Day2, and Night. Each mode controls the
routing of incoming line calls and settings for station and line Class Of Service restrictions. The
system can be programmed to use all three modes, Day/Night mode only, or just the Day mode. The
system switches automatically from one mode to the next based on the system’s time-of-day clock.
Example Day/Night Mode Applications:
•Incoming Calls – Incoming line call routing of individual DID and DNIS numbers or ground/
loop start lines change their ringing destinations automatically according to the date and time of
day.
For example: On workdays, calls are routed to the attendant, individual telephones, ACD groups,
etc., until 5:00 p.m. After 5:00 p.m., calls are routed off-primes to another office, to the Night
Bell, or to night announcements and voice mail message boxes. On holidays and weekends, calls
are routed independently to the appropriate holiday announcements or voice mail message boxes.
•Class Of Service – Station, lines, and DID numbers are assigned 38 options in Class of Service.
These include Toll Restriction, Override privileges, allowed tandem connection, security code
administration, etc. Any of these options can be changed independently for each telephone, line
and DID number when the system switches from one operating mode to another.
For example: When the system changes from the Day to Night mode, selected stations can be
automatically restricted from dialing outside or long distance calls. Note that outgoing route
selections set in LCR are switched using a route selection schedule that is independent of the
Day/Night mode schedule.
•System Call Forward – The System Call Forward settings for stations can be changed
automatically when the system changes from the Day to Night mode. For example: During the
day, a telephone can forward to a person’s car or cell phone, and at night automatically forward
to the person’s voice mailbox.
Features
Delayed Ringing
66 Strata CTX General Description 10/04
•Tenant Services – Up to eight different tenants can each have different attendant or night bell
assignments for day-of-the week schedules using Day 1, Day 2, or Day 3 modes. This feature
is enabled in system programming.
The system also enables users to manually change the Day/Night operating mode, even if the
system is using the Auto Schedule feature. A Night Transfer button can be set on telephones for
manually switching at any time from one mode to another. The button’s LED flash rate indicates
the system’s operating mode.
If used with the System Auto Schedule operation, the Night Transfer button overrides the
current Auto Schedule mode. However, when it is time for the system to switch to another mode
per the Auto Schedule timer, the system will switch to the mode set by the Auto Schedule.
Example: If the system is switched from Day to Night at 2 p.m. manually with the Night Transfer
button (Auto Schedule is set to switch from Day to Night at 6 p.m.), the system will still
automatically switch back to the Day mode at 8 a.m. the next morning per the Auto Schedule.
Delayed Ringing
System Availability: All systems
If an incoming CO, DID or Tie line or internal [DN] call rings a station [DN] and is unanswered,
alternate DKTs can be programmed to ring at a later time. A separate delayed ring time can be set
for each CO line group. The stations that were ringing initially will continue to ring after the Delayed
Ringing begins. This feature is assigned for each line or [DN] button independently for each DKT.
With Strata CTX Release 1.3 and higher, you can assign Delayed Ringing to voice mail and auto
attendants. This feature can also be used to ring multiple (25 max.) telephones immediately or with
a delay to voice mail, auto attendant and/or standard telephones by dialing a group pilot number.
Each group member can have Immediate, Delayed Ring 1 or Delayed Ring 2. Delayed Ring times
are adjustable (1~180 seconds) for each Multiple Call Group.
Destination (Toll) Restriction
System Availability: All systems
Strata CTX offers Destination Restriction as a major expansion of traditional Toll Restriction.
Historically, Toll Restriction was used to prevent the unauthorized use of toll prefixes to the PSTN:
long distance (1), operator assistance (0) or international (011).
Strata CTX has expanded this to include restriction based on any string of dialed digits. A true,
international business telephone system, Strata CTX can restrict any string of up to 11 dialed
digits, including * and #. Eleven-digit screening allows control of access to individual telephone
numbers in remote Area Codes. Restriction of * and # controls users’ access to vertical service
codes from the CO, such as Camp On and Call Forwarding.
A stations’s Destination Restriction level can be changed automatically with Day/Night mode
Auto Scheduling. One use of this feature is to allow a telephone to make outside calls during the
day, but to restrict them at night.
Through Dialing
A telephone user or an attendant can connect a destination-restricted station to a trunk enabling
temporary access to an outside line. The connected station can then use external dial tone to complete
the call, and revert back to destination-restricted status after the call is completed. This maintains the
integrity of toll restriction, while still extending outgoing calling privileges when necessary.
Features
Direct Inward Dialing (DID)
Strata CTX General Description 10/04 67
Direct Inward Dialing (DID)
System Availability: All systems
This feature allows external callers to dial directly to individual extensions or groups of telephones
without intervention by an operator, IVR or auto attendant. Each incoming DID number, which is
sent to the CTX on a DID line from the CO, can be routed individually to an extension, pooled or
group line button, ACD group, maintenance modem, external page, night bell, voice mail box, or
back out over the public or private telephone network. DID routing assignments can change
automatically when the system switches between the Day and Night Modes.
DID numbers can vary between 1~7 digits in length for each DID line group. Each DID number
can be assigned to 1 of 15 possible music-on-hold sources.
DID service is provided by DID analog, T1, or ISDN line interfaces.
Dialed Number Identification Service (DNIS)
System Availability: All systems
DNIS lines receive 800- and 900-type telephone calls that provide the number the caller dialed to
reach the Strata CTX. The Strata CTX translates the DNIS number into a name that displays on the
telephone’s LCD. This allows the user to identify where the call is coming from and the purpose of
the call before the call is answered.
The DNIS Name/Number routes calls to specific telephones, departments or ACD groups. When
the call is ringing and after it is answered, the DNIS Name/Number displays on the telephone’s
LCD. The name and number display can also be sent to an agent computer to be used by a CTI
application.
Applications include sending DNIS calls to a group of agents that take orders for a number of
different companies and products. The agents know how to answer the calls from the DNIS
display. Using DNIS capabilities allows one group of lines to be used to serve multiple
applications. DNIS service is provided by DID analog, T1 or ISDN line interfaces and provides the
same call routing options and destinations as DID calls.
Digital Pad
System Availability: All systems
The Strata CTX digital pad (decibel loss) is activated for the receiving path of the terminal,
external line or resource.
The system adjusts for differing transmission levels between internal and external devices. This is
very useful for conference calls when external parties have difficulty hearing due to public
network loss. The Strata CTX can be programmed to insert the appropriate digital pad for each
terminal and call type when establishing speech paths between telephones, external lines, and
resources such as conference circuits, external paging devices, and external sound sources. This
minimizes volume loss in conference calls.
The system recognizes these devices:
• Standard analog telephone (Type 500, Type 2500 and the equivalent)
• Toshiba digital telephone, cordless, wireless, door phone
• Analog trunk
• T1 trunk
Features
Direct Inward System Access (DISA)
68 Strata CTX General Description 10/04
• ISDN extension terminal (Audio and Speech)
• ISDN trunk/Tie line (Audio and Speech)
• Conference circuit
• Holding music source
• External paging device
Direct Inward System Access (DISA)
System Availability: All systems
Direct Inward System Access (DISA) allows outside callers to connect to the Strata CTX and
make station or trunk calls as if they were stations within the system. An incoming call may be
directed to DISA by Direct Inward Dialing lines, ground/loop start lines or Automated Attendant.
Note DISA lines require DTMF receivers.
DISA security code is changeable from a specific station. The station to change the security code
needs to be allowed by Class of Service. This security code can also be changed using the Strata
CTX WinAdmin administration console.
DISA provides access to the features listed below:
• Station Calls
• Station Calls over Private Network
• Attendant Access
• Account Codes
• Tie lines
DISA also provides access to these features, which require a security code:
•LCR
• Direct line access
• Outgoing line group access
•Emergency Call
• Call Forward Remote Control
Directory Numbers
System Availability: All systems
A Directory Number [DN], sometimes called an “extension number,” is the number someone must
call to reach a destination within the system. Each [DN] is assigned to a flexible button on a digital
telephone or as the main directory number of a standard telephone. To maximize call coverage
flexibility. Any [DN] can appear on multiple telephones. Also, individual telephones can have
multiple [DN] buttons with different Directory Numbers.
The system provides Primary and Phantom [DN] buttons on telephones. All [DN] buttons can be
used to originate and answer calls. If you press a [DN] while on a call, it releases the existing call
and provides dial tone to make another call.
Features
Distinctive LED Indicator
Strata CTX General Description 10/04 69
Primary [DN] Buttons
Primary Directory Number buttons [PDNs] are needed to make calls and receive calls. It is a
telephone’s main extension number. Each telephone is assigned only one [PDN] and that telephone
is designated as the owner of the [PDN]. This [PDN] button can be made to appear multiple times
on the owner telephone and on other telephones (see Phantom [DN] Buttons). Features, Class of
Service, etc., are associated only with the station assigned as the owner of the [PDN]. [PDNs] that
appear on telephones other than the owner telephone are referred to as Secondary DNs [SDNs].
Phantom [DN] Buttons
Phantom [DN] buttons [PhDNs] are additional directory numbers appearing on telephones as
extension buttons. [PhDNs] can be used as independent extensions on the phone or can appear on
multiple phones to be used to allow call handling for departments or groups of telephones.
[PhDNs] can be used to make a telephone appear to have multiple [PDN] extension buttons. When
assigning a [PhDN] for use as another appearance of the [PDN], the display properties are set the
same as the [PDN] and a hunting sequence is set up to roll the calls from the [PDN] over to the
other [PhDN]s associated with the [PDN]. With this arrangement, Call Forward will send calls to
the [PDN]’s destinations and Voice Mailbox.
Pilot [DN]
A Pilot [DN] is a pseudo-location that is assigned a [DN] where calls may be directed. Unlike
[PDNs] and [PhDNs], a Pilot [DN] is not a button on any telephone. A Pilot [DN] is used as a
device where calls can ring and be held while an external application using the Computer
Telephony Interface (CTI) can control the call. To ensure calls do not get lost in the Strata CTX, a
time-out and overflow service is provided to redirect the call when the link is down. Calls being
held on the Pilot [DN] using the CTI link can specify any of the 15 on-hold music sources that are
possible on the Strata CTX.
Pilot DNs are also assigned to Station Hunt Groups (for details, refer to Station Hunting).
Distinctive LED Indicator
System Availability: All systems
Each feature button on a digital telephone has a Light Emitting Diode (LED) indicator. Distinctive
LED indicators provide a method for quickly identifying the status of a line or feature button. The
LED color or flash pattern can identify the call you are currently on, as well as other calls you are
controlling, versus other calls that may appear on your telephone. Each telephone uses dual-color
LEDs: green for lines you are using; red for lines used by someone else.
Distinctive Ringing
System Availability: All systems
Users sometimes need to distinguish the ringing of one button on their phone from another button
and sometimes stations in close proximity to one another need to distinguish the calls on one desk
from another. Typically, multiple sounds are used to provide this distinction. Distinctive ringing
can be assigned to each Line or [DN] button on each telephone.
With Strata CTX Release 1.3 and higher, you can set up to ten different incoming ringing tones for
internal, as well as external calls. Previously, distinctive ring was not provided for internal calls.
Features
Do Not Disturb (DND)
70 Strata CTX General Description 10/04
Do Not Disturb (DND)
System Availability: All systems
Station users with digital telephones can activate DND to prevent any calls from ringing their
telephone. Callers will hear a fast busy tone when calling stations in the DND mode. Stations in
DND mode can originate calls normally; however, they receive DND stutter dial tone (optional)
when originating calls. With Release 1.3 and higher, users can disable DND stutter dial tone (1/2
sec. burst of busy tone before dial tone) in programming.
Call Forward-Busy will forward calls directed to a telephone with DND set, even if the telephone
has idle [DNs]. Telephones with DND Override capability can ring DND telephones (see “Do Not
Disturb (DND) Override” on page 88).
Direct Station Selection (DSS) Buttons
System Availability: All systems
[DSS] buttons can be placed on digital telephones, add-on modules and DSS consoles. When
placed on one of these devices, these buttons serve two functions: to make direct calls or transfer
calls to other stations; and to display the status of other stations and [PDNs].
The [DSS] button is numbered with a station’s [PDN] and when pressed, calls that [PDN]. [DSS]
buttons are not [DN] buttons, so they do not provide dial tone when pressed. The [DSS] button
LED shows the status of the station and [PDN] it represents (idle, busy, DND or ringing). The
[DSS] LED will turn on steady or flash at a unique rate, depending on the status (see “[DSS]
Button Status Display.”
The [DSS] LED displays the telephone’s status for any type of call on any button, including
[PhDN] and Line buttons. The [DSS] LED also indicates the status of the station’s [PDN] itself. If
the [PDN] appears as a Secondary DN [SDN] on multiple telephones, the DSS status will display
Busy if any telephone is using the [SDN].
[DSS] Button Status Display
Red, steady: Busy on a call not connected to your telephone
Green, steady: Busy on a call connected to your telephone
Red, quick flash rate: Ringing
Red, slow flash rate: Do Not Disturb
DTMF Receivers
System Availability: All systems
DTMF receivers are used when receiving incoming DNIS DID, Tie or DISA line calls and when
originating calls with standard tone-dial telephones. Voice mail systems also require DTMF
receivers for a number of VM features, even if using SMDI or Toshiba Proprietary VM
integration. Four circuits are automatically active with the initial basic processor. Activation of
more than four receivers requires the purchase of a DTMF software license, in four-circuit
increments.
DTMF receivers require an optional ARCS subassembly on the CTX100 processor and are built
into the CTX670 processor. For the number of receiver circuits, refer to Table 12 on page 26.
Features
Emergency Call
Strata CTX General Description 10/04 71
DTMF Back Tone
The system can be programmed to allow or prevent Dual-tone Multi-frequency (DTMF) tones
from being returned to digital telephones when a user dials on outside lines or sends DTMF digits
to a voice mail device.
DTMF and Dial Pulse CO Line Compatibility
When making outside calls, signals generated by pressing the dial pad buttons of a digital
telephone are neither DTMF nor rotary dial signals – they are digital signals. The system can be
programmed to translate these signals to either DTMF or rotary dial signals as required by the
serving CO. Once the connection has been made, any further digits sent will always be sent as
DTMF or rotary to allow the operation of devices at the other end of the connection.
DTMF Signal Time
DTMF tones that are sent via Speed Dial to lines and via automatic dialing to voice mail devices
can be set to 80 or 160 milliseconds, or continuously. The time can be set system wide
independently for line out-dialing and for voice mail automatic dialing.
Emergency Call
System Availability: All systems
An Emergency Call access code can be established in the Strata CTX to route calls to specified
emergency destinations and to prioritize their delivery to those destinations. Up to four emergency
destinations can be programmed for each mode of operation: Day, Day2 and Night. This is
particularly useful in applications where employees, patients or guests are not expected to know
where to call for help at different times of the day.
Feature Prompting with Soft Keys
System Availability: All systems
As an alternative to dialing access codes and using feature buttons, station users with LCD digital
telephones use Soft Keys (shown on their LCD) to access features. Abbreviated feature names
appear during a call (when the telephone is in the ring or talk state) on the LCD above fixed keys.
Users can select a feature by pressing the associated key. The LCD feature selections change
according to the call state to provide the most logical options.
Enhanced E911
System Availability: All systems
Enhanced 911 calling means the routing of a call to the appropriate Public Safety Answering
Position (PSAP) accompanied by Caller Emergency Services Identifier (CESID). The CESID
identifies the location to which emergency services are to be sent. The Strata CTX can use two
types of trunks to deliver E911 calls: ISDN Primary Rate Interface and CAMA (Centralized
Automatic Message Accounting) trunks. Each 911 call generates an SMDR record at the
beginning of the call to enable the business to initiate its own emergency response. Internal
emergency destinations can also be automatically included in an emergency call. E911 calls can be
routed across a Strata Net network for connection to the public network.
Features
External Amplified Speaker
72 Strata CTX General Description 10/04
External Amplified Speaker
System Availability: All systems
The External Amplified Speaker (HESB) is a six-inch, three-watt speaker with a three-watt
amplifier built into a wooden speaker box. The amplified ringer can be used to:
• Amplify the ringing on a digital telephone.
• Provide a paging amplifier/speaker.
• Create an amplified talk-back speaker arrangement in an area where a telephone is not needed.
The HESB is installed as a speaker and connected to a door phone unit that is used as the talk-
back microphone.
Amplified ringing can improve call handling in noisy areas where non-amplified ringing on a
phone may not be heard.
A paging speaker ensures that paging announcements can be clearly heard throughout an area. In
an area where a DKT is not needed, a talk-back speaker provides a cost-effective communications
solution.
The number of HESBs that can be installed per system depends on the function of the HESB. Any
number of HESBs can provide loud ringers for digital telephones. Only one HESB can be installed
if it is used as a paging or an amplified talk-back speaker.
Note A BHEU interface and an HESC-65A cable are required for each digital phone that has a
loud ringing bell. IP telephones require HESC-65A, but not BHEU to support External
Amplified Speaker. A 3000- or 2000-series digital telephone that has been upgraded with a
data interface unit can be upgraded with the BHEU options, but older telephone models
cannot.
Flash Button
System Availability: All systems
This is an optional button that can be assigned on digital telephones. It can be used either to
disconnect a line and regain CO dial tone, or to gain access to Centrex features. The timing choice
is set system wide through system programming. Standard telephones can dial an access code to
flash Centrex lines.
Flexible Line Ringing
System Availability: All systems
CO line ringing can be assigned to ring a specified [DN] on a station, a [DN] appearing on
multiple stations, a Pilot [DN], a direct appearance of the CO line, a Pooled appearance of CO
lines, or Group CO line appearance. These assignments direct the ringing of the incoming call
based upon the three Day/Night Modes of operation and offer immediate and two delayed ringing
parameters. The delay parameters are assigned for each incoming Line Group.
Features
Flexible Numbering
Strata CTX General Description 10/04 73
Flexible Numbering
System Availability: All systems
The Strata CTX allows the system-numbering plan to be customized for the user’s needs.
Directory numbers, line and feature access codes, and Network Coordinated Numbering can be
established uniquely in each system.
Handsfree Answerback
System Availability: All systems
When a voice-announced internal [DN] call comes in to a digital telephone, users can answer
without lifting the handset. Cordless and single line digital telephones and standard telephones are
not compatible with this feature.
Headset
System Availability: All systems
3000-series digital telephones may be optionally equipped with a modular headset jack by
installing a BHEU circuit card.
Hearing Aid Compatible
System Availability: All systems
All Toshiba digital telephones are hearing aid compatible.
High Call Volume Buttons
System Availability: All systems
Release, Release/Answer, and Cancel buttons can be assigned to digital telephones. They
enable a busy user to handle calls quickly and efficiently in high call volume situations.
With one touch of the Release button, a user can disconnect from a call. This is especially useful
in headset applications. The Release/Answer button disconnects or transfers the current call,
and answers the next. The Cancel button voids the last operation, such as disconnecting internal
or external parties from conference or tandem calls.
Features
Hold
74 Strata CTX General Description 10/04
Hold
System Availability: All systems
There are several variations of Hold:
Automatic Hold
This option enables a user to place a CO Line or [DN] call on Hold by pressing another CO Line or
[DN] button. The user can then alternate between the new and the old call by pressing the desired
Line or [DN]. If this feature is not activated, users must press Hold before accessing another line
and switching between calls.
Analog Hold
This option enables a user to place a CO Line or [DN] call on Hold and the Line LED will flash on
other DKT telephones when the call is parked. This enables the call to be picked up from other
telephones. This feature must be set in programming.
Call Hold
This is the most commonly used. Call Hold temporarily suspends a call, allowing the station user
to do other things, including using the phone. Callers on hold can receive music or announcements
as described in the Music-on-hold feature.
Consultation Hold
This is used when invoking other call features, such as Call Transfer or Conference.
Exclusive Hold
A call can be placed on Exclusive Hold to ensure the privacy of the connection and that the call
can only be retrieved by you, even if the held call appears on buttons on other telephones.
Hold Recall
After placing a call on hold, it will recall the holding telephone after a predetermined time to
remind the user of the held call. The hold recall time is set independently for each telephone (from
0~255 secs.). Hold recall time can also be disabled.
Hot Dialing
System Availability: All systems
Hot dialing enables the digital telephone user to begin on-hook dialing without pressing a Line or
[DN] button. The station can be programmed to automatically select a Line or [PDN] button when
the dial pad is pressed while the station is idle. This saves a keystroke by not requiring the station
user to press a [DN] or Line button to begin on-hook dialing. On-hook dialing saves time by not
requiring the station user to lift the handset to begin dialing.
Hotline Service
System Availability: All systems
If a station remains off hook for a programmable period, it can automatically be directed
(immediately or with a delay) to a pre-programmed destination. The station may have partially
dialed a number or have dialed no digits at all.
Each station is programmed with its specific ring down destination. This is particularly useful in
applications where employees, patients or guests are not expected to know where to call for help at
different times of the day. This feature is compatible with standard and digital telephones.
Features
IP Telephony
Strata CTX General Description 10/04 75
IP Telephony
Data Network Assessment for Voice Traffic
System Availability: Strata CTX100, CTX670
Important! Voice over Internet Protocol (VoIP) can be affected by numerous factors related to
network structure and design. To prevent delays, jitter and voice data packet loss,
and achieve optimum VoIP traffic performance, your network must be designed or
redesigned for voice traffic with priority over data.
Toshiba highly recommends that the installing dealer assess the existing network for proper
handling of voice traffic and make sure it provides the required bandwidth per the number of
deployed VoIP instruments. Toshiba is not responsible for: network assessment for voice traffic,
network design/redesign or network support outside the topology it provides. Nor is Toshiba
responsible for diminished Quality of Service (QoS) caused by networks not capable of providing
necessary VoIP bandwidth.
Expected voice QoS as it relates to network parameters is shown in Table 41 on page 112.
Overview
The CTX supports Toshiba proprietary IP telephones, enhancing the CTX VoIP capabilities, and
providing powerful IP telephony add-on solutions for remote users. The Toshiba IPT1020-SD IP
telephone is compatible with Strata CTX100 and CTX670 systems with R2.0 or higher software.
The Toshiba IP telephony strategy is based upon a transitional approach. For most enterprises, the
migration path to IP telephony will be a gradual process rather than an event in time. Instead of
acquiring IP technology benefits through complete system replacement at higher cost and higher
risk, most enterprises prefer to integrate voice and data IP traffic into their existing telephone
systems as the need arises. This protects their investment in existing voice and data networks and
represents a low risk migration path. Toshiba has transformed Strata CTX systems into IP-enabled
communication systems to achieve this very important objective.
IP Telephone
System Availability: Strata CTX100, CTX670
The Toshiba IPT1020-SD IP telephone supports almost all the same Strata CTX features as 3000-
series digital telephones, extending the functionality of the Strata CTX to any location supported
over an IP network. The only feature the IPT1020-SD telephone does not support is Speaker Off-
hook Call Announce, but it does support Off-hook Call Announce over telephone handset. (For a
photo, see “IP Telephone” on page 43).
CTX IP Protocol
System Availability: Strata CTX100, CTX670
CTX IP uses an industry standard IP communication protocol, RFC3015 Media Gateway Control
(MEGACO+). Toshiba chose the MEGACO+ protocol for call control because it provides better
stimulus response that makes the telephone work efficiently over the IP network local area or wide
area network (LAN or WAN). In fact, Toshiba uses an enhanced version of MEGACO+ that
enables the Strata CTX to provide all the feature functionality of DKT3000-series telephone to IP
telephone users much better than could be done using other protocols.
This represents a very powerful feature set, as compared to many competitors’ IP telephones
which don’t support important telephone features such as:
Features

• Busy Lamp Field (BLF) display of station status
• Background Music through telephone speakers
• Paging over telephone speakers
• Off-hook Call Announce over telephone handset
IP Telephone Features
System Availability: Strata CTX100, CTX670
The Toshiba IPT1020-SD IP telephone is
a 20-button speakerphone with a two-line
by 24-character display. It looks and
functions just like a DKT3020-SD digital
telephone; however, it has different built-
in connectors (shown right):
• The AC adapter (model BADP120-
1A supplied with the IPT1020-SD)
powers the telephone if PowerDsine’s
Power Over LANTM is not used (see
“Power Over LAN” on page 80 for
details). IPT1020-SDs do not use the
CTX power supply, so there is no
power restriction to limit the number
of IP telephones that can connect to an
individual Strata CTX cabinet.
• The RJ45 LAN jack connects the
telephone to the network via the
10Base-T/100Base-TX cable supplied
with the IPT1020-SD. The IPT1020-
SD operates on the network at 10/100
Mbps and can be connected to a fast
switch hub, router, LAN, WAN, etc.
• The RJ45 PC jack can connect the IPT1020-SD to the user’s PC. The IPT1020-SD can operate
like a switch, as opposed to a hub, so the telephone can be connected directly to the LAN or
Cable/DSL modem, and then a PC can be connected to the telephone PC jack to connect to the
LAN through the telephone.
• The built-in headset jack enables headsets to be connected to the telephone. No optional
headset interface is required. The same carbon or ECM headsets used on Toshiba digital
telephones can be used on IP telephones.
The IPT1020-SD also has the following attributes and capabilities:
• The IPT1020-SD contains two types of codecs (coder/decoder): G.711 and G.729A. The codec
determines the IP telephone voice quality and network bandwidth requirements. The G.711
requires the most bandwidth and provides the best voice quality. The G.729A requires less
bandwidth, but it does not provide the best voice quality. The desired codec is selectable for
each IP telephone in IP station administration using CTX WinAdmin.
• The external ringer interface connector is mounted inside the telephone base. This enables
connection of an HESB external speaker device to provide a loud ringer for the IP telephone.
• Existing tilt stands (BTSD and BTSA) are compatible with then IPT1020-SD to adjust the
angle of the telephone as desired.

• There is no limit to the number of IP telephones that can be configured on Strata CTX systems.
All telephones in the system can be IP telephones up to the system’s maximum station capacity
(see Table 9 on page 23).
• Terminal Authentication is an option that allows a particular IP telephone to keep a reserved
directory number on a CTX system. This prevents IP telephones from logging in with another
telephone’s directory number if the other telephone has been disconnected to be taken to
another location. This feature uses the unique Media Access Control (MAC) address that is
permanently coded into each telephone network interface circuit. The unique MAC address of
the telephone is assigned to a particular directory number in system programming.
• IPT firmware can be updated locally or remotely using CTX WinAdmin. This enables service
personnel to update IP equipment with new features and enhancements as they become
available. Updates require a brief interruption of IP telephone operation (a few minutes).
• IP telephones have a discovery retry timer to prevent network congestion when many IP
telephones request services simultaneously. If network congestion is detected, the telephone
will pause and then retry for service.
• IP telephones have loop back and ping capabilities for maintenance and fault finding purposes.
• IP telephones support Dynamic Host Configuration Protocol (DHCP) or static IP addressing.
For a photo of the IPT1020-SD, see “IP Telephone” on page 43.
IP Add-on Module
System Availability: Strata CTX100, CTX670
A 20-button Add-on Module (DADM3120) is available for use with the IPT1020-SD IP telephone.
It looks and functions just like a DADM3020 digital Add-on Module. The DADM3120s can
connect to the IPT1020-SD IP or DKT3000-series telephones to provide 20 or 40 additional
feature or DSS/BLF buttons.
IP Interface Unit
System Availability: Strata CTX100, CTX670
The IP interface unit (BIPU-M2A) is a 16-port circuit card that installs in a slot in the Strata CTX.
The BIPU-M2A has the following attributes and capabilities:
• The BIPU-M2A can be programmed in software to activate 16 channels to interface with
IPT1020-SD telephones.
• The BIPU-M2A supports both G.711 and G.729A standard codec compressions simultaneously.
The type of compression used is set independently for each telephone in system programming
(see the “IP Telephone” section.)
• With the BIPU-M2A, the IP telephone will now work with DSL and cable routers.
The BIPU-M2A operates on the network at 10/100 Mbps and can be connected to a fast switch
router, LAN, WAN, etc. When connecting remote IP telephones to the BIPU-M2A over the
Internet, a VPN router is needed to circumvent Network Address Translation (NAT) and
firewall issues by tunneling. Otherwise, the BIPU-2MA must be configured with a public IP
address outside the network firewall.
• BIPU-M2A provides MEGACO+ mobility to enable roaming with Toshiba Mobility
Communications System (MCS) applications (available with Toshiba MCS R1.0). The
BIPU-M2 enables remote IP telephones to be connected over VPN and non-VPN IP networks.
• BIPU-M2A firmware can be updated locally or remotely using CTX WinAdmin. This enables
service personnel to update IP equipment with new features and enhancements as they become
available. Updates require a brief interruption of IP telephone operation (a few minutes).

IPT Anywhere
System Availability: Strata CTX100, CTX670
IPT Anywhere enables you to connect IP telephones remotely through the Internet and use all Strata
CTX telephone features (except Speaker OCA). IPT remote connections can be set with or without
the use of Virtual Private Network (VPN). VPN connections provide increased security and are
recommended for permanent type IPT remote connections. When moving IPT telephones frequently
to different locations (hotels, conferences, etc.), non-VPN connections are more practical.
When using home type xDSL or cable connections, only one or two IPTs may be connected
because of xDSL and cable bandwidth limitations. High speed T1, fiber, or Asynchronous Transfer
Mode (ATM)-type connections are required when installing more than two IPTs at a remote site.
An Internet configuration could use the following connections:
•No VPN, and thus, no security
•Third party VPN software residing on DHCP gateway server. To connect IPTs over the Internet,
using third party or Microsoft VPN software residing on a DHCP gateway server, see Figure 18.
•ATM (IP over ATM virtualization by VC/VP)
•Broadband Ethernet virtualization by Virtual LAN (VLAN)
•IP-VPN (IP-VPN based on Multi-protocol Label Switching (MPLS)
•Private line connection
For an access line to link the user’s location with the access point of the carrier or provider, using a
private line, broadband line (xDSL, CATV), or fiber optics is recommended.
The IPT Anywhere feature enables remote IP telephone users working in branch offices or home
offices to make full use of the extension features of the Strata CTX. The diagram below shows IPT
Anywhere connections using the optional VPN conection.

Quality of Service (QoS) and Bandwidth
System Availability: Strata CTX100, CTX670
In any telephone system, deploying many IP telephones on a data LAN can have some unexpected
pitfalls if the network does not have the bandwidth and speed required to handle VoIP traffic. To
prevent delay, jitter, and data loss for VoIP traffic and retain the performance of your other
business-critical network applications a Network Voice Readiness Assessment must be completed
before installing VoIP. Toshiba is not responsible for Network Voice Readiness Assessments.
More information about Voice Readiness Assessment can be found at http://www.netiq.com/
products/vm/whitepapers.asp.
CTX IP provides a number of adjustable tuning parameters dealing with sharing of network
resources, collectively referred to as Quality of Service (QoS). Expected voice QoS as it relates to
network parameters, including bandwidth, is shown in Table 41 on page 112.
Some CTX IP voice quality adjustable parameters are listed below:
System Wide Parameters
• Software selectable G.711 or G.729A codecs with variable interval timing
• Type of Service (TOS) precedence, delay, throughput and reliability types can be individually
selected
• Differentiated Services (Diffserv) can be enabled
IP Telephone Group Parameters (256 groups)
• Voice Packet Transmission Interval
• Jitter buffer type
• Jitter buffer length
• Maximum acceptable delay
• Packet loss threshold
• IEEE802.1p
Priority Control
Priority Control can be enabled system wide. It provides a framework in which voice traffic
flowing on an IP network is given priority for processing. The CTX supports IEEE802.1p and
Differentiated Services “Diffserv” priority control protocols- selectable. In order to have priority
control processing work accurately, network equipment (router, switch, etc.) must support this
function and appropriate service must be ordered from the ISP provider or carrier.
QoS Measurement
CTX WinAdmin can measure the IPT QoS parameters listed below:
• Packets (sent/received)
• Delay (msec.)
• Jitter (msec.)
•Loss (%)

80 Strata CTX General Description 10/04
CTX Analog CO Line Interface Compatibility
To provide optimum voice quality of IP telephones and IP QSIT Strata Net networks on Strata
CTX systems, there are some compatibility requirements that must be followed when using analog
CO line cards in the system.
• Toshiba highly recommends only using RCOU3A, RCOS3A, REMU2A (two-wire/four-wire),
REMU1A (four-wire), RDDU2A, and RGLU3A analog CO line interfaces in IP phone
applications. These circuit cards provide optimum speech quality for IPT1020-SD IP phone
connections.
• Do not use RCOU1A, RCOS1A, REMU1A (two-wire), RDDU1A, RGLU1A, or RGLU2A
analog CO line interfaces in IP telephone applications. These circuit cards will work, but will
cause IP telephone users to experience unacceptable voice quality and echo return loss.
Power Over LAN
System Availability: Strata CTX100, CTX670
The IPT1020-SD IP telephone requires local power for operation unless connected to a LAN that
has been equipped with special equipment to provide telephone power over the LAN. The AC
adapter (model BADP120-1A) supplied with the IPT1020-SD powers the telephone and is
included in the price.
If the customer prefers not to use local power in favor of powering the telephones over the LAN,
certain PowerDsine PD-6000 Power Over LANTM products, with software revision 6805 or later,
are compatible with IPT1020-SD usage on a LAN. These products are purchased from
PowerDsine, Ltd., http://www.powerdsine.com, and are not available from Toshiba.
The PowerDsine PD-6000 Power Over LAN products shown in Table 23, with software revision
6805 or later, are compatible with the Toshiba IPT1020-SD. AC and AC/DC models are available.
Important! Whenever ordering PowerDsine PD-6000 “Power Over LAN” products, be sure to
specify they have software revision 6805 or later, and they are for use with the
Toshiba IPT1020-SD IP telephone. You can tell the software version by looking at
the serial number of the PowerDsine unit. The four-digit software version number is
imbedded in the middle of the 15-digit serial number.

Toshiba SoftIPT IP Telephone
System Availability: Strata CTX100, CTX670
The Toshiba SoftIPTTM is an IP telephony client that works with a wired or wireless (Wi-Fi) tablet,
laptop or desktop PC. The Toshiba SoftIPT integrates the power of a PC with all of the features
available on a DKT3000-series telephone, except background music.
With the Toshiba SoftIPT installed on a Wi-Fi laptop PC, users can have true mobility with access
to voice mail, programmable feature buttons, and a directory that works with Microsoft®
Outlook® 2002. (In the future, the SoftIPT will be available for installation on Wi-Fi Pocket PCs.)
SoftIPT operation requires a wired or wireless connection over the IP network (Internet, WAN,
LAN, etc.) to the CTX BIPU-M2A IP interface. The software uses the MEGACO+ protocol for
call control signaling and RTP for voice transmission, allowing virtually all of the features of a
desktop phone to be implemented on a desktop computer.
The Toshiba Soft Phone works on desktop or laptop PC with Windows XP, or higher, operating
systems (OS).
The Toshiba SoftIPT operates much the same as a Toshiba Digital 3000-series telephone (see
Figure 19).
A mouse or stylus is used to click or select the buttons. The Call button operates the same as the
DKT3000-series telephone Spkr button. Additionally, there are multiple feature buttons that can
be customized from telephone programming mode.

Figure 20 Example of SoftIPT Directory
The SoftIPT can be connected to the CTX several different ways:
• Intranet – A wired or wireless PC can connect to the office LAN that connects to an IP
telephone that connects to a BIPU-M2A in the Strata CTX.
• Internet – A wired or wireless PC at a remote site can connect to a Cable or DSL modem, to an
Internet Service Provider (ISP), to a router, to the BIPU-M2A in the CTX (see Figure 21). (For
additional connection examples, refer to the Strata CTX I&M manual – IPT Chapter.)
• Wireless – The wireless PCs, such as the Toshiba Pocket PC or Toshiba Tablet PC need a Wi-Fi
system that uses the 802.11b standard. The SoftIPT wireless units can operate within 300 feet
of an access point (dealer-supplied or use existing).

Private Networking Over Internet Protocol
Strata CTX General Description 10/04 83
Private Networking Over Internet Protocol
System Availability: Strata CTX100, CTX670
Strata Net CTX multi-system networking can be implemented over an IP network using Strata
CTX systems with BIPU-Q1A IP interface circuit cards. The BIPU-Q1A requires CTX Release
2.1 software. This feature offers the same connection service as ISDN dedicated lines with QSIG
protocol on the public network. QSIG over IP, does not support modemized data signals, such as
modem signal and G3 fax because these signals require very low jitter and low delay on the
networks.
The BIPU-Q1A can be configured for up to 16 channels in system programming. The BIPU-Q1A
supports the same functions of call control as the dedicated ISDN QSIG interface and the two
interface types can be mixed in on a Strata Net network. However, the BIPU-Q1A only interfaces
with the BIPU-Q1A, not with the BPTU or RPTU interfaces and vice versa.
CTX private networking QSIG over IP can support up to 128 separate nodes.
For bandwidth requirements, refer to the section “Strata Net QSIG Over IP and IPT Bandwidth
Requirements” on page 112.
Refer to “CTX Analog CO Line Interface Compatibility” on page 80 if you are planning to mix
analog and IP QSIG circuit cards in the same Strata CTX system.
BIPU-Q1A interface parameters include:
• 100Base-TX: Automatic recognition and switch
• Transmission: TCP/IP, UDP/IP
• Protocol: IP QSIG (ECMA-336), NAT compatible
• Protocol: RTP/RTCP for voice transport
• Voice coding: G.711, G.729A, selectable
• Priority process: Diffserv/IEEE802.1p

Integrated Services Digital Network (ISDN)
84 Strata CTX General Description 10/04
Integrated Services Digital Network (ISDN)
System Availability: Strata CTX100, CTX670
ISDN is a set of integrated telecommunications services, available over the public
telecommunications networks. ISDN makes it possible to send, receive and modify information
using telephone lines in ways that were not previously possible, such as:
• Dynamic use of individual or groups of standard (POTS), DID, Tie, FX, WATS, 800 lines on an
as-needed basis
• Much faster call setup and data transfer up to 128Kbps
• Multi-purpose line use, including sharing lines for voice, data, fax, and video
• DID functionality based on the number dialed; without needing to reserve a block of numbers
• 2-B channel transfer: Allow two external PRI line calls conected to a station conference to be
released from the CTX and reconnected by the PSTN when the station drops out of the
conference. Requires CTX R2.0 or above and special ordering from the ISDN provider.
ISDN service comes in two forms:
•Primary Rate Interface (PRI) supports simultaneous voice or data connections (eight, 16 or
23). PRI is similar to digital T1 service and uses two pairs of wires from your phone company.
The RPTU circuit card supports PRI on the Strata CTX.
•Basic Rate Interface (BRI) supports up to two simultaneous connections using a single pair of
wires. The Strata CTX BRI cards support both station side and trunk side connections. Strata
CTX systems also support BRI interface from the public network as a CO line service. There
are two types of ISDN BRI interfaces: S/T type (via RBSU/RBSS) and the
U-type (via RBUU/RBUS).
Least Cost Routing (LCR)
System Availability: All systems
Least Cost Routing chooses the most appropriate route over which to connect an outgoing call
based on the following:
• Dialed Digits
•Time of Day
• Type of Day (Business, Weekend, Holiday)
• LCR group of the caller
The combination of routing tables, indices, route definitions and time-of-day qualifiers can
produce up to 75 million combinations. Routing changes automatically for each type of day,
according to the time of day. This schedule is independent of the Day/Night mode schedule which
applies to ringing and CO assignments.
Line Buttons
Telephone buttons that are used for making and receiving outside calls are referred to as Line (or
CO Line) buttons. (For information on various [DN] buttons, refer to “Directory Numbers” on
page 68.) The Strata CTX supports the following types of line buttons:
Features
Live System Programming
Strata CTX General Description 10/04 85
CO Line Buttons
System Availability: All systems
Smaller systems have traditionally provided the direct appearance of the CO lines on the
telephones where maximum visibility of the line status, flexible ringing assignments, and informal
call transfers associated with key telephone systems may be implemented.
Pooled CO Line Button
System Availability: All systems
Pooled Line Group buttons enable a group of CO lines to “appear” under one button. Pooled and
single appearing line buttons are designed for use with loop and ground start lines, not Tie, DID,
DNIS or ANI lines.
Group CO Line Button
System Availability: Strata CTX100, CTX670
Group CO line buttons are like individual CO line buttons except these buttons represent all the
lines for a particular ISDN Channel Group. This enables ISDN channels to operate similar to
analog CO lines on a key telephone system. These buttons may have appearances on multiple
telephones providing call coverage across several telephones. Multiple appearances of the same
Group CO line button is possible on each phone to allow multiple call handling for that group from
each station.
Live System Programming
System Availability: All systems
Programming the Strata CTX from an on-site or off-site location does not interrupt the operation
of the system in most cases. It is interrupted for hardware upgrades.
Lost Call Treatment
System Availability: All systems
Lost Call Treatment provides the CTX a mechanism for terminating calls that cannot be
terminated with the usual calling patterns. One scenario would be a call that is recalled to a station,
the station user is no longer there to answer the recall and no forwarding pattern is programmed.
The call will ring at the recalled station until the Lost Call Timer has expired after which the
system will direct the call to the Lost Call Destination.
Message Waiting
System Availability: All systems
Any station and most voice mail devices can turn on a message waiting indicator for a designated
digital or standard telephone station.
LED Indication
Message waiting lights can be activated when a voice mail message has been left, or they can be
turned on by a calling station. The station user can retrieve messages by pressing the button next to
the message waiting light or by dialing an access code from a standard telephone.
Features
Microphone (External Unit)
86 Strata CTX General Description 10/04
The telephone main Msg light indicates a message is waiting for the telephone [PDN]. Up to four
[PhDNs] per telephone can also have individual MW LEDs assigned to flexible buttons.
Stutter Dial Tone
Stutter dial tone is also used to indicate a message is waiting or your telephone is in the DND
mode. When a station user goes off-hook, two different available stuttered dial tones indicate
whether a Message Waiting (MW) or DND condition exists. The MW-stutter dial tone indicates a
message is waiting for the station. DND-stutter dial tone indicates DND is set at the station. (DND
provides a fast busy tone burst as stutter dial tone.) If both conditions exist simultaneously, the
MW-stutter dial tone has priority. This is very valuable to station users that do not have a MW
Light Emitting Diode (LED) or DND button LED on their telephone. (See Table 38 on page 110
for details of each type of stutter dial tone.) With Release 1.3 and higher, users can disable (in
programming) stutter dial tone for message waiting and when in the DND mode. If stutter dial tone
is disabled, they will hear normal dial tone when you go off hook.
Microphone (External Unit)
System Availability: All systems
An external microphone (RFDM) can be connected to the DKT2020-FDSP digital telephone
enhancing “full-duplex” operation by virtue of the “superdirectional” characteristic of the
microphone. When this option is on, the internal microphone is disabled on all but Voice First
Handsfree Answerback calls and OCA calls. The external microphone is powered by the DKT and
does not need to be turned off when not in use.
Music-on-hold
System Availability: All systems
Music-on-hold can be derived from a customer-supplied radio, tape player, tuner, CD player or
other device to provide music or announcements to parties on hold on CO lines or on [DNs]. With
the Strata CTX, you can have up to 15 MOH/BGM sources. Each CO line group and each DID/
DNIS number may be assigned a specific MOH source. Stations and network Tie lines can also
share a unique MOH source.
Multiple Call/Delayed Ringing
System Availability: All systems
With Strata CTX Release 1.3 and higher, you can assign Delayed Ringing to voice mail and auto
attendants. This feature can also be used to ring multiple (25 max.) telephones immediately or with
a delay by dialing a group pilot number. Each group member can have Immediate, Delayed Ring 1
or Delayed Ring 2. Delayed Ring times are adjustable (1~180 seconds) for each Multiple Call
Group. Multiple calls to digital telephone is supported; however, delayed ring to digital telephones
is not supported as of this printing.
Features
Off-Hook Call Announce (OCA)
Strata CTX General Description 10/04 87
Off-Hook Call Announce (OCA)
System Availability: All systems
Station users may announce a call when the station they call is busy talking with the handset off-
hook. The announcement is only audible to the telephone user receiving the OCA call, not to the
other party in the original conversation.
Two different methods of operation are provided – handset or speaker OCA. With handset OCA,
the OCA caller’s announcement comes in on the telephone handset. With speaker OCA, the
announcement comes in on the speaker. Handset or speaker OCA can be set individually for each
telephone that must receive OCA calls. Speaker OCA requires a BVSU option circuit card
installed in the telephone that receives the OCA call. Handset OCA has no optional hardware
requirement.
When a busy telephone receives a handset OCA call, replying confidentially to the OCA caller can
be accomplished by pressing the Msg button (toggle) to place the original call on hold or holding
down the Mic button to make a short reply. In either case, the original caller will not hear the reply
to the OCA caller. To reply to a speaker OCA call, the user covers the handset mouth piece and
talks back through the telephone microphone.
Any type of telephone can be enabled to originate OCA when calling a busy digital telephone. The
feature is activated automatically (optional setting) or manually (Call Completion code – digit 5).
Stations receiving OCA must be proprietary digital telephones assigned with OCA-receiving
capability in system programming. Standard single-line telephones cannot receive OCA.
Any type of station can make an OCA call, as long as the station has this option enabled in system
programming. OCA to DND telephones is allowed only if DND Override is allowed on the called
and calling telephones.
Off-Premise Stations
System Availability: All systems
Off-premise stations are supported using either standard analog telephones or Toshiba digital
telephones. This can accommodate both individual telephones and branch office connections. Off-
site standard analog telephones can be part of the system, having access to many of the features
offered by the Strata CTX. Each off-site station requires a special OPX line from the CO.
Off-site digital telephones can be part of the Strata CTX system using MCK Branch Office
EXTenders. This is ideal for organizations with geographically dispersed locations, extending the
power of the main location’s Strata CTX to small branch offices over your existing data network.
This enables groups of remote workers to use Toshiba digital telephones to have seamless access
to the main location’s telephone system and voice mail system.
Remote employees have transparent access to all the same capabilities as if they were locally
connected to the Strata CTX system. They have can the same ability transmitting voice traffic and
digital telephone signaling over the customer’s existing Local Area Network (LAN) Wide Area
Network (WAN) private IP packet network or the public Internet.
Features
Override
88 Strata CTX General Description 10/04
Override
System Availability: All systems
Call Forward Override
Stations with this feature will not forward when they call stations that have System or Station Call
Forward activated. This applies when using the telephone dial pad or [DSS] button to make a call.
It also applies to [DSS] buttons on DSS consoles or add-on modules associated with the Call
Forward Overriding telephone.
Class Of Service Override
By dialing a Class of Service Override (COS) code, a user can change a station’s class of service to
one associated with the override code. When the call is terminated and another is attempted from
the same station, the original Class of Service is applied. This allows selected users to override toll
restriction or other restrictions that are placed on any telephone in the system.
Do Not Disturb (DND) Override
A privileged caller may invoke the DND Override feature after dialing an internal station and
receiving a DND indication. If that privilege is granted to the calling station and the called station
permits its DND to be overridden, the call will ring on that phone.
Executive Override
Stations with this feature allowed by COS can enter any conversation in the system by dialing a 3
or pressing a Feature Prompting Soft Key after dialing a busy station. An optional warning tone
notifies the parties that another party is about to conference into their conversation. Executive
Override can be blocked selectively to any station in system. Executive Override must be allowed
in system programming for the called and calling station.
The Do Not Disturb feature can also be used to block Executive Override; however, stations that
are allowed DND Override can use Executive Override on stations in the DND mode. The
Privacy button does not block Executive Override.
Privacy Override
Privacy override controls the ability of multiple station users with a shared (common) Line or
[DN] button appearance to join in each other’s conversation by pressing the busy button
appearance. A station must be programmed with Privacy Override to permit the intrusion on a
shared Line or on [DN] buttons.
In the case where Privacy Override is normally allowed, a telephone can have a “Privacy” button
to block Privacy Override (intrusion) to the call. The Do Not Disturb feature does not block
Privacy Override. In the case where Privacy Override is not normally allowed, a telephone can
have a “Privacy Release” button to allow intrusion to the call by any station with the shared button
appearance. (See “Privacy” for more information.)

Paging
Strata CTX General Description 10/04 89
Paging
System Availability: All systems
The Strata CTX has a paging interface that supports a Toshiba External Speaker (HESB) or a
customer-supplied amplifiers and speakers for Paging, Night Ringing over Page, and BGM
applications. Users can access any of the Paging options by dialing access codes or by using a
programmed One Touch button.
Telephone Group Paging
Paging is activated from an extension by specifying a Paging Group. Paging can be broadcast
through digital telephone speakers and external paging devices simultaneously. The system
supports up to 16 telephone page groups with up to72 (CTX100) or 120 (CTX670) telephones per
group. Standard telephones cannot be members of a page group.
External Speaker Page Zones
The Strata CTX supports eight different paging zones for external speakers. Users can access
zones by dialing an access code plus the zone or pressing a One Touch button. The zones are
composed of customer-supplied speaker(s) and amplifier(s). One BIOU supports up to four page
zone interfaces, a second BIOU is required for 5~8 zones.
Emergency Page
Designated stations can be permitted to place an Emergency Page to ensure they can reach all
concerned with an important announcement. An Emergency Page is one that will supersede any
current page to allow this privileged station to take over the paging apparatus. Like other forms of
paging, an Emergency Page can be an All Page or directed to a specific Page Group and External
Page Zones.
Each of the 16 Paging Groups supports up to 32 devices. Emergency Page groups follow the
regular Group Paging. The list for Emergency All Call Paging is a separately defined list from
regular paging. An emergency page may be answered in the same manner as a regular page.
Night Ringing Over Selected Page Zones
Lines can be programmed to night ring over eight selected Page zones via customer-supplied
paging equipment. Up to two BIOU circuit cards can be installed to connect external paging or
night ringing equipment. Each BIOU supports up to four page zones.
Power Failure Protection
System Availability: All systems
The Strata CTX has important optional capabilities that keep the system operating when
commercial AC power is interrupted.
Power Failure Transfer
The Strata CTX can immediately switch loop start analog CO lines directly to dedicated standard
telephones (customer-provided 2500- or 500-type) for incoming and outgoing calls in the case of a
commercial AC power failure. The transfer is automatic with no manual transfer procedure
required. During normal operation with AC power, the Power Failure telephones function with all
Features
Privacy
90 Strata CTX General Description 10/04
Strata CTX features available to a normal standard telephone. This feature requires an external unit
called the Power Failure Transfer Unit (DPFT).
Each DPFT provides interface for eight power failure telephones. A Standard Station Interface
(RSTU) circuit card is required to supply the DPFT with a -24VDC control power and ground
connections. The number of Power Failure telephones available depends on system configuration.
The system maximum is 264.
Reserve Power Battery Backup
Two or four 12-volt gel-cell, maintenance-free batteries can be connected to the CTX system
power supplies for system battery backup (80 amps./hours max.). The CTX670 system power
supply is standard-equipped with a battery charger and the batteries continuously trickle charge to
capacity while electrical power is present. The CTX100 power supplies must be equipped with the
optional ABCS battery charger to charge reserve power batteries.
If the AC power fails, the Strata system automatically switches over to battery power without any
interruption in operation. Calls in progress are not interrupted. Battery operation duration depends
upon the condition and ampere hour rating of the batteries and the system load. However, the
minimum battery operation time would be several hours. Connection of reserve power batteries
must be made when commercial AC power is available.
Privacy
System Availability: All systems
Privacy prevents intrusion on calls that appear on shared (common) [DN] or line buttons. If a
telephone has a call on a [DN] or line button that appears on other telephones, the other telephones
cannot intrude on the call by pressing the shared button unless the intruding telephone has the
Privacy Override feature or the telephone with the call activates the Privacy Release button.
Repeat Last Number Dialed
System Availability: All systems
This feature enables a digital station to automatically redial the last number dialed from their
station by selecting an outgoing line and pressing the Redial button or by dialing an access code.
Digital key telephones have a fixed Redial button for automatic redialing of the last number
dialed.
Ringing
System Availability: All systems
Ring Over Busy
When a digital telephone is busy on a call and then receives an internal or external call on an idle
[DN] or line button, the button will automatically flash and ring with Ring Over Busy tone. The
tone burst can either be sent two times (three seconds apart) or repeated continuously every three
seconds or not sent as a station option. To answer a Ring Over Busy call, the user can hold, transfer
or disconnect the existing call.
On Voice First calls to a busy telephone that has an idle [DN], the caller will get busy tone. The
caller can then dial the digit 1 to cause the idle [DN] to Ring Over Busy.
Features
Speed Dial
Strata CTX General Description 10/04 91
Ringing Cadence
With Release 1.3 and higher, you can choose between two different ringing cadences for standard
telephone circuits in programming. This option is necessary to accommodate some voice mail and/
or auto attendant devices. This is a system wide option that allows external calls to ring with the
traditional one sec. on./three sec. off cadence or optionally with a faster cadence of .4 sec. on./.2
sec. off. This option does not apply to digital telephones. If ringing cadence is used, Centrex ring
repeat must not be used.
Delayed Ringing
See “Delayed Ringing” on page 66.
Distinctive Ringing
See “Distinctive Ringing” on page 69.
Speed Dial
System Availability: All systems
This feature, sometimes known as automatic dialing or one-touch dialing, enables the customer to
assign dialing codes to telephone numbers that are frequently called. Strata CTX offers three forms
of Speed Dial: System Speed Dial (up to 800 max. per system), Station Speed Dial (100 max. per
station), and One Touch buttons. Station Speed Dial numbers and One Touch buttons are unique
for each station and cannot be used by other stations. System Speed Dial numbers can be used by
any station in the system.
To dial System and Station Speed Dial numbers, the user presses the Spdial button and then dials
the appropriate three-digit code for the telephone number to be dialed. To dial a telephone number
assigned to a One Touch button, the user simply presses the One Touch button. Users can program
Station Speed Dial and One Touch buttons from their telephones.
CTX WinAdmin is required to program System Speed Dial numbers and can also be used to
program Station Speed Dial numbers, but not One Touch button numbers. Each Station and
System Speed Dial number can be assigned a nine-character name using CTX WinAdmin.This
name appears in the DKT3014 large LCD screen System Speed Dial and Personal Speed Dial
directories.
One Touch Buttons
One touch buttons enable users to store speed dial and custom feature access sequences on a single
button. When this button is pressed, the stored number is dialed or the feature is accessed.
You can store frequently dialed numbers, such as three-digit System Speed Dial codes, onto a One
Touch button. This eliminates the need to enter the three-digit code to dial a System Speed Dial
number. Complete telephone numbers up to 32 digits can also be stored on a One Touch button.
These buttons make it easy to access features that usually require pressing multiple buttons and/or
dialing special access codes. For example, a user may have to dial an access code (#31) plus a
zone number (5) to page the warehouse. This sequence can be set on a One Touch button labeled
“Page Warehouse.” Another button can be set to page a particular group of telephones.
The One Touch button also has a “stop” function that can be entered between two numbers, such
as a telephone number and security code. When the One Touch button is pressed, it can speed dial
a telephone number, then pause (LED flashes). When the call is answered, it prompts for a security
code. The user can then press the flashing button and enter the security code. Any number of
“stops” can be set to enable dialing multiple numbers.
Features
Station Hunting
92 Strata CTX General Description 10/04
Multiple feature buttons such a Cnf\Trn, [DN], CO line, etc., can be set on One Touch buttons to
allow multiple button presses to be stored under one button. This enables tandem line connections
and other call setup sequences to be dialed easily by pressing one button.
Station Hunting
System Availability: All systems
A series of Directory Numbers (DNs) can be organized in groups in such a way that if a called
[DN] is busy the call will try to ring another [DN] in the group. If that [DN] is busy it will hunt to
a third [DN], etc. Telephones in the same department, voice mail ports and boss/secretary call
coverage situations are typical applications for hunt groups. Hunt group members can remove
themselves from the group by placing their station into the Do Not Disturb mode. The system
supports three types of station hunting:
Serial Hunting
In this type of hunt group, calls hunt [DNs] in a series from first to last in a specific order. When
any [DN] in the series is called, the system will ring the first idle [DN] in the series, starting with
the called [DN], hunting to the last [DN] in the series. As an option, this type of hunt group can
have a unique Pilot [DN] assigned to it. When callers dial the Pilot [DN] to reach a telephone in
the group, calls will hunt all [DNs] from first to last.
Circular Hunting
In this type of hunt group, calls hunt [DNs] in a series in a specific order; however, the series forms
a loop, which enables the last [DN] to hunt to the first [DN]. When any [DN] in the series is called,
the system will ring the first idle [DN] in the series, starting with the called [DN], hunting to all
[DNs] in the series. As an option, this type of hunt group can have a unique Pilot [DN] assigned to
it. When callers dial the Pilot [DN] to reach a telephone in the group, calls will hunt all [DNs] from
first to last.
Distributed Hunting
This type of hunt group always has a unique Pilot [DN] assigned to it. Callers dial the pilot [DN] to
reach a telephone in the group. Calls hunt in such a way so as to distribute the calls evenly to each
[DN] in the group. Hunting rotation always starts in sequence with the [DN] that follows the [DN]
that received the last call – even if all other [DNs] are idle.
Camp on to Hunt Groups
On incoming CO line calls to busy hunt groups, the caller automatically camps on to the called
[DN] or Pilot [DN] and the caller receives ring-back-tone.
On internal calls to busy hunt groups, the caller may get busy tone. The caller can then dial a digit
to initiate Camp On-Busy to the called, busy [DN] or the Pilot [DN], if used. As an option, for
each hunt group that uses a Pilot [DN], calls will automatically camp on to the called Pilot [DN].
With the Automatic Camp On option, the caller does not get busy tone, instead the caller receives
confirmation tone followed by ring-back-tone. When using hunt group Pilot [DNs], camped on
calls queue onto all [DNs] in the group and will connect to any [DN] in the group that becomes
available. When not using Pilot DNs, Camp On is only applied to the called [DN].
When more than one party is camped on (queued) to a hunt group, the party with the highest
Queuing Priority Level (QPL) will be connected first when the destination becomes available. If
the parties have the same QPL, the longest waiting call will be connected first.
Features
Station Message Detail Recording (SMDR)
Strata CTX General Description 10/04 93
Station Message Detail Recording (SMDR)
System Availability: All systems
For each incoming, outgoing or tandem call, the Strata CTX can generate a record that includes
details of the call, including the originating station or trunk, the start time of the call, its duration,
authorization codes, etc. If a station user dials “911,” the Strata CTX will also generate a record at
the beginning of the call as part of its internal notification that an emergency call is in progress.
SMDR requires an optional BSIS interface circuit card and a connected Call Accounting system.
Strata Net Multi-system Networking
System Availability: Strata CTX100, CTX670
Strata Net is a private networking application based on QSIG, an international standard for inter-
connecting PBXs. Strata Net delivers a rich set of calling features across multiple CTX systems
throughout the enterprise. Users benefit from transparent dialing and simple feature operation.
Advanced networking features include Centralized Voice Mail, Centralized Attendant, Network
SMDR and Station DSS button appearances across all nodes. Alternate Routing provides for toll
bypass configurations and automatic recovery from network disruptions.
Strata CTX systems are interconnected with DS1 (T1) circuits to provide ISDN-type inter-
connectivity. DS1 circuits may be leased from public carriers, derived from Frame Relay or IP
networks, or connected across twisted-pair cabling or fiber optics.
QSIG over IP also provides full Strata Net connectivity and capabilities over an IP network (VPN
WAN, Internet or intranet).
Up to 128 nodes can be accommodated within the Strata Net numbering plan. Up to four nodes
connected in tandem can give satisfactory performance with regard to latency. As with any
network design, transport, delay speech volume and other issues must be carefully considered.
You can set up network DN tables across nodes. Through system programming, you can attach a
node ID to non-redundant DNs, PhDNs and Pilot numbers. This enables someone in one node to
call an extension in another node without having to dial the node ID number. The caller dials the
extension and the system automatically routes the call to the node in which the called extension is
located and rings the called extension.
Coordinated Numbering Plan
System Availability: Strata CTX100, CTX670
Strata Net can be configured to allow users to call each other across network nodes with simple
network directory numbers. This eliminates the user’s need for access codes and network maps.
Calls that encounter a busy or unanswered destination can be forwarded to any node in the
network, including a centralized voice mail system or attendant.
QSIG Basic Call Control
System Availability: Strata CTX100, CTX670
The Strata CTX conforms to the QSIG standard for Basic Call Control. This is the basis for all
Strata Net connectivity and interoperability with PBXs from other manufacturers. Basic Call
Control provides for connection, dialing, identification of calling and called parties’ names and
numbers and message waiting indications among other features.
Important! Toshiba does not guarantee interoperability with other manufacturer’s products:
only conformance to the standard.
Features
Strata Net Multi-system Networking
94 Strata CTX General Description 10/04
Alternate Routing
System Availability: Strata CTX100, CTX670
Each Strata CTX can be programmed for thousands of routing patterns for Strata Net alone. This
allows the creation of networks in which calls can be automatically re-routed around network
disruptions. Centralized facilities and features can continue to work and users will be unaware of
problems while they are being repaired.
Alternate Routing also permits Toll Bypass in which Strata Net can be used to deliver a public call
from a point in the network where toll charges are minimized. Such a scheme is known as “Hop
Off” for the ability of the private network to determine the point at which the call will hop off to
the public network.
Centralized Attendant
System Availability: Strata CTX100, CTX670
One attendant can serve an entire Strata Net (requires Strata CTX R1.3 and higher, as well as CTX
Attendant Console application R1.3 and higher). Station users only need to dial “0” to reach the
centralized attendant regardless of the node in which they reside. The attendant can reach any
station in the network using its Network Directory Number. Trunks attached to any network node
can be programmed to terminate to the centralized attendant and their source and calling party
information will be delivered to the attendant’s display. The BLF appearances of all stations from
all nodes can appear on the centralized Attendant Console.
Telephone DSS Buttons
System Availability: Strata CTX100, CTX670
Telephone DSS buttons can appear across the QSIG network. This enables a user’s DSS button to
function in all nodes in a CTX network. The DSS function works within or across a network.
Centralized Voice Mail
System Availability: Strata CTX100, CTX670
Requires Stratagy ES or iES Release 4 or higher. A voice mail system attached to any Strata Net
network node can serve users throughout the enterprise. Unanswered calls will be forwarded to the
voice mail, the source and calling conditions identified and the appropriate voice mailbox greeting
will be played. The voice mail system can control message waiting indications throughout the
network as messages are left and retrieved. A single network can even support multiple centralized
voice mail systems with each station being programmed for the appropriate system. Record to
voice mail and voice mail soft keys are available across all network nodes from a single Stratagy
R4 ES or iES voice mail system.
Network SMDR
System Availability: Strata CTX100, CTX670
An external Strata Net call will generate a call record at the terminating node for that call. Transit
nodes will not generate records. The records can be stored in customer-supplied external buffers at
each node. Polling call accounting software can gather and organize the data from multiple nodes.
Local buffering provides survivability in the event of network disruption.
Features
System Fault Finding and Diagnostics
Strata CTX General Description 10/04 95

The Strata CTX can detect problems in the system. These conditions can be detected, alerted,
logged, and traced. Strata CTX includes many useful diagnostic tools.
Alarm Indication of System Faults
Visual Alarms are presented to CTX WinAdmin.
SmartMedia Card
This is a small memory card that is commercially available in retail stores. It is the same as
SmartMedia cards used in digital cameras, MP3 players, etc.
The Strata CTX uses the SmartMedia card to store all error, trace logs and a backup copy of the
system operating software and the customer database. The SmartMedia card is inserted into a
socket on the CTX processor. The CTX processor creates directories and files onto the card for
maintenance functions. Using CTX WinAdmin enables moving, copying, or deleting these files
without having to remove the SmartMedia card from the CTX processor. With CTX WinAdmin,
this works locally or remotely. SmartMedia files can also be managed by removing the
SmartMedia card from the CTX processor and inserting it into a PC SmartMedia card read/write
adapter.
Fault Detection and Error Logs
The Strata CTX detects and logs abnormalities that it encounters during operation. All error and
trace logs are stored on the SmartMedia card on the system processor and are monitored by
CTX WinAdmin. Examples are trunk failure detection and auto busy-out, digital telephone port
failure detection and auto busy-out plus error log, Expansion Cabinet power supply failure alarm
and error log, etc.
Event and System Administration Logs
Events such as station buttons pushed or lines accessed are stored in an Event Log. All actions
made by the System Administration user are logged. Both logs may be called up at a later time.
Automatic Fault Recovery
The system can automatically correct certain conditions detected during operation. This enables
the system to continue operating normally without requiring correction.
System Trace
The system records telephone key strokes and other high level events and presents the data in a
format understandable and useful to the field technician for troubleshooting purposes. The system
also records more detailed data useful to a software support engineer.
Manual Test
The maintenance technician can perform certain test functions using CTX WinAdmin to determine
proper operation of the system.
Features
Transfer
96 Strata CTX General Description 10/04
Backup/Restore

database is a file that can be stored on the SmartMedia card, transferred to the PC hard drive,
e-mailed, etc.
Maintenance and Administration
The CTX WinAdmin terminal can be connected directly to the Strata CTX or via the customer’s
LAN as well as remotely over the Internet and via modem over the public network. The Strata
CTX processor comes standard with a network interface port and a built-in modem.
Software Upgrade
The Strata CTX operating software can be upgraded using the SmartMedia card or by
downloading it from a remote location. The operating software is a file that can be stored on the
SmartMedia card, transferred to the PC hard drive, e-mailed, etc.
Transfer
System Availability: All systems
Transfer is the ability to redirect a connected call to new destination. The Strata CTX provides
three means of transferring a call and three means of terminating transferred calls, depending on
the calling state of the destination. The transferring features and the terminating features may be
used in combination to serve most needs that arise.
Transfer with Camp On
This feature enables the transfer of a call to a busy destination. The transferred party automatically
camps on to the busy destination when the transferring party releases the call.
Transfer Immediate
Call Transfer Immediate simplifies the transfer of calls for users of digital display telephones. With
a conversation in progress, the display phone user presses the TRNS Soft Key and dials the transfer
destination. The calling party is placed on Consultation Hold, the call immediately transfers and
the transferring phone returns to idle. This feature does not apply to network calls.
Transfer Privacy
An outside call that has been transferred can only be answered at the station to which the call has
been transferred. Another station cannot pick up the transferred call using a common CO line
button unless it is another station using the Directed Call Pickup feature or a station that has a
[DN] appearance of the “transferred to” [DN]. A flashing red LED indicates the call is transferred.
Privacy for transferred calls can be disabled in programming.
Transfer (Screened)
The transferring party can talk privately with the receiving party before connecting the party to be
transferred. While that conversation is going on, the transferred party is on Consultation Hold
listening to Music-on-hold. When the receiving party agrees to accept the call, the transferring
party can use the switch hook or feature button to include the original party in the conversation. At
this point, the transferring party can hang up and the other two parties remain connected.
Features
Tenant Services
Strata CTX General Description 10/04 97
Transfer (Unscreened)
Unscreened Transfer allows the transferring party to exit the connection before the transfer
destination answers. After the destination answers the call, the system treats it as a regular call. If
the destination does not answer the call within the predetermined time of period, the transferring
party is recalled.
Transfer to Voice Mail
See “Direct Transfer to Voice Mailbox” on page 99.
Music or Ringing Option
This feature enables ringing or music to be heard by the caller when their call is transferred,
depending on system programming.
Tenant Services
System Availability: All systems
This feature enables one CTX to provide separate service to multiple companies or departments
(tenants). PDNs (including ISDN BRI PDNs), DIDs and incoming line groups (ILGs) can be
assigned to one through eight tenants. Each tenant can have different attendant or night bell
assignments for day-of-the week schedules using Day 1, Day 2, or Day 3 modes. This feature is
enabled through system programming.
User Programming Mode
System Availability: All systems
Digital telephone users can use the programming mode for customizing their Toshiba telephones
without the aid of an Administrator or Service Technician. The User Programming mode is
accessed with a Program button assigned to a flexible button or through an access code. User
Programming enables users to customize these features:
•Flexible Buttons – Toshiba telephones have 10, 14, or 20 flexible buttons to which the user can
assign any one of approximately 50 different features (DND, ACB, Release, etc.). Once
assigned to a button, the feature is accessed by pressing that button. Some buttons have
parameters that users can set. These include:
•Call Forward – Users can set the Call Forward (CF) destination and CF-No Answer Timer
for the CF buttons.
•One Touch – Users can set speed dial and custom feature access code sequences for
One Touch buttons.
•Background Music – Users can select the music source (up to 15 sources) that will play on
their telephone’s speaker when they activate the BGM button.
•Ring tones – Line and [DN] button ringing tones can be changed to one of four different
tones. These tones apply to direct or transferred incoming calls from outside lines, not
internal calls.
Note Directory number and external line buttons cannot be added or deleted, but their ring tones
can be individually changed.
In addition to the Programming Mode, an advanced programming function enables administrators
to individually turn On/Off the telephone’s beep tone, handset call waiting tone, and microphone
background noise cancellation option. This mode enables LCD contrast adjustment and testing the
DKT3014 large LCD screen.
Features
Voice or Tone Signaling
98 Strata CTX General Description 10/04
Voice or Tone Signaling
System Availability: All systems
Each [DN] button can be programmed for either Voice or Tone Signaling as the standard method
of internal incoming call signaling. Tone Signaling rings the telephone when a call comes in and
ensures better privacy. With Tone Signaling, the called telephone receives a one-second ring tone
every three seconds. The pitch and sound of internal tone signaling is always the same. Incoming
CO line ringing is uniquely different, with up to four optional ring tone sounds.
With Voice Signaling, station users will hear a tone burst followed by the caller's voice over their
telephone speaker when called by another station user locally or over the private network. Voice
Signaling allows handsfree talkback from the called telephone on internal and private network Tie
line calls.
After calling a directory number that has Voice Signaling, the caller can switch to Tone Signaling
by dialing 1. The signaling method can also be switched from Tone to Voice Signaling by dialing
2. Whether a call is initiated with Tone or Voice Signaling, it can always be switched back and
forth by dialing 1 or 2.
Note A call to a Voice Signaling [DN] will not Call Forward No Answer unless the signaling is
switched from Voice to Tone Signaling.
Voice Mail Integration
System Availability: All systems
The CTX670 supports Dual-tone Multi-frequency (DTMF) integration, Simplified Message Desk
Interface (SMDI) integration, and Toshiba Proprietary integration.
DTMF Integration
DTMF integration uses DTMF strings to pass and interpret information between the Strata CTX
and a voice mail system. DTMF integration can be used with any compatible voice mail system. It
does not require optional hardware interface.
Simplified Message Desk Interface (SMDI)
SMDI is an industry standard method of integrating a telephone system with voice mail or other
peripheral systems. This interconnection is made via an RS-232 data connection. SMDI requires
the BSIS interface in the Strata CTX. SMDI integration can be used with any compatible voice
mail system.
Toshiba Proprietary Integration
Toshiba proprietary integration provides the highest functionality between the Strata CTX and a
Stratagy voice processing system. Toshiba proprietary integration requires the BSIS interface for
control signaling between Stratagy and Strata CTX. Toshiba proprietary integration is required to
use Stratagy voice processing system’s support the features of Call Record to Voice Mail and Voice
Mail Soft Keys.
Call Record to Voice Mail
While on an active call, a station user can record the conversation and store it in a Stratagy ES
voice mailbox by pressing Record on the digital telephone. To end the recording, they can press
Record again. Station users can also stop and start recording by pressing PS/RES.
Features
Volume Control
Strata CTX General Description 10/04 99
Users can replay recorded messages by calling the voice mailbox that has the stored recording and
play it back as any other message. The “record to” mailbox can be any mailbox number and can be
accessed automatically when Record is pressed or dialed after Record is pressed.
Recording to Voice Mail (VM) is available on two-party and multi-party conference calls.
Voice Mail Soft Keys (Stratagy ES/iES32 Only)
Voice Mail Soft Keys provide LCD telephone
users with an active set of Soft Keys that prompt
the user with available commands to play Voice
Mail messages and to manage their mail boxes
(shown right).
The LCD shows the number of New and Saved
messages in the user’s mailbox.
The number of New/Saved messages displays on
the LCD when the telephone is idle and has at least
one new message.
Soft Keys requires the Toshiba Proprietary VM
integration and connection to the Strata CTX LAN.
Direct Transfer to Voice Mailbox
The transferring party can transfer a call directly to a person’s voice mailbox without waiting for
the call to forward from the called party’s telephone. The voice mailbox does not need to be
associated with an active telephone in the Strata CTX. Direct transfer to voice mail (VM) can be
performed to a centralized VM system connected to a network node other than the user’s node.
The transferring party presses Direct Transfer to VM and dials the mailbox number, and the
call transfers immediately on receipt of the last digit. The transferred party hears the greeting
associated with the specified mailbox and can then leave a message.
Direct Transfer to Voice Mailbox simplifies getting a call for a busy or absent employee to his/her
mailbox. It eliminates the need for the caller to enter the desired mailbox number after being
connected to the voice mail system. This feature is available using standard DTMF or SMDI VM
integration and does not require Toshiba proprietary VM integration.
Volume Control

Reserve Power
Two or four customer-supplied 12VDC reserve batteries (80 ampere-hours max.) can be connected
to either system to maintain normal operation during a power failure (see Tables 27~31). The
batteries are kept in a highly-charged state by the power supply’s battery charger and must be
connected when the system is operating normally. Fully charged batteries must be connected when
normal AC power is available, batteries cannot be connected after/during an actual power failure.
The battery changer is standard on the CTX670 power supply. An optional ABCS battery changer
must be used in the CTX100 power supply.

Strata Net QSIG Over IP and IPT Bandwidth Requirements
112 Strata CTX General Description 10/04
Strata Net QSIG Over IP and IPT Bandwidth
Requirements
The amount of bandwidth required for communications over a particular IP network segment
depends on the number of voice channels supported, the anticipated call setup traffic, and how
much other data network traffic is present.
The quality of service (Excellent, Good, Fair, and Poor) provided by CTX IP QSIG channels and
IP telephones depends heavily on the LAN parameters as shown in Table 41. This table shows the
amount of bandwidth required for each IP QSIG voice call (without data traffic) based on the
interval and the CODEC.
Table 41 Strata Net QSIG Over IP and IPT Quality of Service
IP Network Quality Parameters
Speech
Excellent: No one
perceives delay.1
1. Ratings of Excellent, Good, Fair, Poor were based on the tester in a quiet room and the tester could not see the other call
party.
Good: Very few
people perceive
delay.1
Fair: Some people
may perceive
delay.1
Poor: Many people
may perceive delay.1
IPT is usable even
with a "Poor" rating if
delay is acceptable.
Latency (Round trip delay)2
2. When selecting router equipment, the Latency, Jitter, Packet loss and Packet error conditions above should be considered as
well as the bandwidth. Bandwidth can be calculated with the CODEC and packet size. For better results, more bandwidth may
be required, depending on the amount of overall data traffic. For more details on QoS refer to “A Handbook for Successful
VoIP Deployment: Network Testing, QoS, and More” by John Q. Walker, NetIQ Corporation on www.netiq.com.

Strata Net QSIG Over IP and IPT Bandwidth Requirements
Strata CTX General Description 10/04 113
When sharing voice and data on the same network segment, the data will cause some jitter in voice
communications, especially on slower segments. Table 42 shows calculations of the amount of
jitter assuming a worst case data packet size of 1500 bytes (Maximum Transmission Unit (MTU) =
1500) based on a segment’s bandwidth. This also requires that the routers connecting the segment
through the WAN support Diffserv.
Note A router that doesn’t support Diffserv may stack multiple data packets together increasing
the jitter perhaps indefinately. And the voice quality will be indeterminate.
Class definition categories are shown in Table 43.
Table 44 shows the amount of bandwidth required for setting up and tearing down calls
independent of the amount of voice traffic.
So the amount of bandwidth that is required on a segment to support a specific number of calls is
the sum of the number of channels multiplied by the bandwidth for the selected CODEC and
interval, plus the bandwidth required for the selected number of busy hour call attempts. And the
jitter is determined by the bandwidth of the WAN segment.
Example: If you want to support 4 calls using the G..711 CODEC with a 20 msec. interval, this
requires 4 x 88 kbps = 352 kbps of bandwidth. In addition, to support 1000 busy hour call
attempts, 6 kbps must be added for a total of 358 kbps. If only voice is going to be carried on the
segment, then a 384 kbps segment (6 B-channels) is sufficient. If voice and data are going to be
mixed on the segment, then at least 25% (89.5 kbps) should be added, or more, based on the
amount of data traffic desired. In this case, a total of 447 kbps will be required which would best
be supported by a 512 kbps segment (8 B-channels). This would result in an expected jitter of 20
ms in the voice traffic.
