Strata CTX100 and CTX670
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 Requirements
Means of Connection: The Federal Communications Commission (FCC) 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.

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.

Limited Warranty
Toshiba America Information Systems, Inc., (“TAIS”) warrants that this telephone equipment (except for fuses,
lamps, and other consumables) will, upon delivery by TAIS or an authorized TAIS dealer to a retail customer in new
condition, be free from defects in material and workmanship for twenty-four (24) months after delivery. This
warranty is void (a) if the equipment is used under other than normal use and maintenance conditions, (b) if the
equipment is modified or altered, unless the modification or alteration is expressly authorized by TAIS, (c) if the
equipment is subject to abuse, neglect, lightning, electrical fault, or accident, (d) if the equipment is repaired by
someone other than TAIS or an authorized TAIS dealer, (e) if the equipment’s serial number is defaced or missing, or

respect to the equipment, is the repair or replacement by TAIS or its authorized dealer of such defective or missing
parts as are causing the malfunction with new or refurbished parts (at their option). If TAIS or one of its authorized
dealers does not replace or repair such parts, the retail customer’s sole remedy will be a refund of the price charged by
TAIS to its dealers for such parts as are proven to be defective, and which are returned to TAIS through one of its
authorized dealers within the warranty period and no later than thirty (30) days after such malfunction, whichever
first occurs.
Under no circumstances will the retail customer or any user or dealer or other person be entitled to any direct, special,
indirect, consequential, or exemplary damages, for breach of contract, tort, or otherwise. Under no circumstances will
any such person be entitled to any sum greater than the purchase price paid for the item of equipment that is
malfunctioning.

INC., OR TOSHIBA CORPORATION WHICH EXTEND BEYOND THE FACE OF THIS WARRANTY. ALL
OTHER WARRANTIES, EXPRESS OR IMPLIED, INCLUDING THE WARRANTIES OF
MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND FITNESS FOR USE, ARE

Strata CTX100 Overview

The Strata CTX100 is a compact system that
provides large system features (see
Figure 1). It is designed for wall mounting and
occupies very little space.

Base

Expansion

The CTX100 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 (Base and Expansion)
cabinet system can support up to 112 CO lines
and stations.
System line and station capacity is expanded by
adding CO line and station Printed Circuit
Boards (PCBs) 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.

Strata CTX100 Overview
CTX100 Processor

CTX100 Processor
The system operates with one processor circuit board (ACTU2) that installs in a dedicated slot of
the Base Cabinet. The ACTU2 processor has built-in receivers and other interfaces than the earlier
ACTU1 model. The ACTU2 processor incorporates the following hardware features:

CPU/Memory
The CTX100 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 processor has LSI circuits that support the following:
• The ACTU2 provides a built-in 10/100 Base-T Ethernet LAN interface. The Ethernet LAN
Interface provides one 10baseT Ethernet circuit with an RJ45 connector for CTI Open
Architecture applications, CTX Attendant Console, ACD Server, Toshiba Proprietary Voice
Mail integration and system administration connection (including local and remote CTX
WinAdmin).
• 16 DTMF receiver hardware circuits are built into the ACTU2. Five or more DTMF receivers
requires appropriate licenses. See “CTX100 License Control” on page 4.
• 16 Busy Tone (BT) detector circuits for Auto Busy Redial (ABR) are built into the ACTU2.
• 64 built-in conference circuits (see Table 7 on page 14 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, 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.

External Page Interface
A 600 ohm RCA jack is built into the 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 the processor to interface with Music-onhold 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 PCBs, each provides three MOH/BGM input sources
• An RSTU PCB that provides up to eight MOH/BGM input sources

Strata CTX General Description

The Strata CTX670 system provides sophisticated
telecommunication features in a modular system
designed for growth. Its universal slot architecture
enables you to select the combination of Central Office
(CO) lines, stations, and peripheral options that best suit
your needs.
The CTX670 basic processor can be configured for
smaller systems as a one or two cabinet system with a
capacity of up to 192 CO lines and stations combined. It
can expand to support up to seven cabinets with a
capacity of up to 672 CO lines and stations combined
(see Figure 3).
System line and station capacity is expanded by adding
processor expansion Printed Circuit Boards (PCBs),
cabinets and line/station PCBs.
The CTX670 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.
The Base Cabinet and optional Expansion Cabinets are
the building blocks of the system. Each system has a
Base Cabinet, and can have from one to six Expansion
Cabinets. All lines, stations, and options are tied together
through the cabinets.

Expansion Cabinet Interior

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 PCB. 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
PCB 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 PCBs. Network clock synchronization can only be derived from digital trunks
installed in the Base Cabinet (Master) location.
A Remote Cabinet can support all PCBs 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.

Telephone Upgrade Options

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).

5843

Up to two DADMs can be attached to a telephone to provide 40 buttons to supplement the
telephone’s 10 or 20 buttons.
The CTX supports a limited number of DADMs per cabinet (see Table 4 on page 11 for the
capacities of different common control units).
Telephones with Add-on modules cannot support the Integrated PC Interface (BPCI).

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.

Strata CTX General Description

Telephones and Peripherals
Telephone Upgrade Options

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-2004CT 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. IPT1020SDs do not support Speaker OCA, but they do support Handset OCA.

CTX Attendant Console

CTX Attendant Console
The Strata CTX Attendant Console runs on a PC with Microsoft® Windows® XP or 2000
operating systems. The Strata CTX Attendant Console PC requirements include:
• Pentium III running at 500 mHz or better
• 256M RAM (Windows XP) or 128M RAM (Windows 2000)
• 500MB hard disk space
• NIC interface for 10/100 Base T
It connects to the Strata CTX processor via the LAN as a Customer Supported Telephony
Application (CSTA). It also connects to a digital station port for the speech path. The console
consists of the following items:
• CTX Attendant Console software application (may be supplied on CD-ROM only or preinstalled, both options are available)
• Keyboard
• Special Attendant Keyboard stickers (CTX-KL-ATCON-VA).
• Mouse
• Color VGA monitor (600x800 pixels) or better
• Attendant Console Interface Unit (BATI), which connects to the BDKU or PDKU station
interface on the Strata CTX. Plus, a handset and cradle (BATHC). A headset can be ordered
...or
a DKT3001 can be used as the station interface. If a headset is used, it connects to the BHEU
installed in the DKT3001.
Important!

• If a DKT telephone is connected to the CTX Attendant Console PC, the keyboard must be used
for all Attendant operations when the console is running. (When the console is in Position
Busy, it is still running.)
• When the Attendant Console software is not running, the DKT3001 telephone can be used for
regular calling. Calls intended for an Attendant (Dial “0”) when the software is not running
will follow the Alternate Destination programmed in Strata CTX. Only calls directed to the
DKT’s primary extension number will ring the phone.
• If the handset interferes with the headset, you can unplug the handset while using the headset.
The Strata CTX670 system supports up to four, and the 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.

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 PCBs 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 28 on page 91).
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

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
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)
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 33.

Advisory Messages
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.

Alternate Answer Point
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.

Features
Automatic Busy Redial

Automatic Busy Redial
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
An external ACD software option with the Strata CTX provided by connection of an external PCbased 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)

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)
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 . 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
This feature automatically connects a telephone to a specific line or extension button when the user
lifts the handset off-hook, presses the 6SNU (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

Automatic Release
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)
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
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

Call Forward
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 predetermined 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.

Strata CTX General Description

Features
Call History

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 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 73.

Call History
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 &DOOHU,' button.
When calls ring a button (/LQH or [DN]) that appears on multiple stations, the number is stored on
the telephone that is designated as the owner of the /LQH 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

Strata CTX General Description

Features
Call Park

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 7 on page 14.

Call Park
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 7 on page 14 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.

Call Pickup
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
When a station is busy with a call and another call is directed to that station’s busy /LQH 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.

Strata CTX General Description

Features
Caller Identification

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.

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 7 on page 14 for the number of call records per station and system.

ISDN Calling ID Name and Number
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
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.

Strata CTX General Description

06/03

Features
Cancel Button

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 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).
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 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 77 for more details).

Cancel Button
The &DQFHO 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, &DQFHO will disconnect the last party added to the conference.

Centrex/PBX Compatible
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
The system can mimic CO/Centrex/PBX ringing cadences received from outside lines when it
rings a called station.

Strata CTX General Description

Features
Classes of Service (COS)

Classes of Service (COS)
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.

Computer Telephony Integration (CTI)
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
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
&DQFHO 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 /LQH button on his phone. The Hold state of the conference can be released from
another station by pressing the /LQH 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.

Features
Continuous DTMF Tone

Releasing from 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 &DQFHO button.

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
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
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.

CTX WinAdmin
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
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.

Features
Day/Night Mode – Auto Schedule

Day/Night Mode – Auto Schedule
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 the
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.
The system also enables users to manually change the Day/Night operating mode, even if the
system is using the Auto Schedule feature. A 1LJKW7UDQVIHU 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 1LJKW7UDQVIHU 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
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.

Strata CTX General Description

06/03

Features
Destination (Toll) Restriction

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
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.

Direct Inward Dialing (DID)
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)
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.

Strata CTX General Description

06/03

Features
Digital Pad

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
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
• 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)
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

Strata CTX General Description

06/03

Features
Directory Numbers

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
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.

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).

Strata CTX General Description

06/03

Features
Distinctive LED Indicator

Distinctive LED Indicator
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
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 /LQH 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.

Do Not Disturb (DND)
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 73).

Direct Station Selection (DSS) Buttons
[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 /LQH 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].

Features
DTMF Receivers

[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
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 7 on page 14.

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
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.

Strata CTX General Description

06/03

Features
Feature Prompting with Soft Keys

Feature Prompting with Soft Keys
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
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.

External Amplified Speaker
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 talkback 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.

Strata CTX General Description

06/03

Features
Flash Button

Flash Button
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
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.

Flexible Numbering
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
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
3000-series digital telephones may be optionally equipped with a modular headset jack by
installing a BHEU PCB.

Hearing Aid Compatible
All Toshiba digital telephones are hearing aid compatible.

High Call Volume Buttons
5HOHDVH, 5HOHDVH$QVZHU, and &DQFHO 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 5HOHDVH button, a user can disconnect from a call. This is especially useful
in headset applications. The 5HOHDVH$QVZHU button disconnects or transfers the current call,
and answers the next. The &DQFHO button voids the last operation, such as disconnecting internal
or external parties from conference or tandem calls.

Strata CTX General Description

06/03

Features
Hold

Hold
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
/LQH or [DN]. If this feature is not activated, users must press +ROG 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
Hot dialing enables the digital telephone user to begin on-hook dialing without pressing a /LQH or
[DN] button. The station can be programmed to automatically select a /LQH 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 /LQH 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
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.

Data Network Assessment for Voice Traffic
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 35 on page 96.

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 both Strata CTX100 and CTX670 systems with Release 2.0 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
The Toshiba IPT1020-SD IP telephone supports almost all the same Strata CTX features as 3000series 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 Offhook Call Announce, but it does support Off-hook Call Announce over telephone handset. (For a
photo, see “IP Telephone” on page 31).

CTX IP Protocol
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:
• 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
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 builtin connectors (shown right):
•

The AC adapter (model BADP1201A supplied with the IPT1020-SD)
powers the telephone if PowerDsine’s
Power Over LANTM is not used (see
“Power Over LAN” on page 66 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 IPT1020SD operates on the network at 10/100
Mbps and can be connected to a fast
switch hub, router, LAN, WAN, etc.

6682

• 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.

Strata CTX General Description

Features
IP Telephony

• 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 4 on page 11).
• 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 31.

IP Add-on Module
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
The IP interface unit (BIPU-M2A) is a 16-port PCB 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.)
• 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 not needed to circumvent Network Address Translation (NAT) and
firewall issues by tunneling.
• 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).

Features
IP Telephony

IPT Anywhere
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:
•
•

•
•

Quality of Service (QoS)
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 is shown in Table 35 on page 96.
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

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.

CTX Analog CO Line Interface Compatibility

To provide optimum voice quality of IP telephones 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 telephone
applications. These PCBs provide optimum speech quality for IPT1020-SD IP telephone
connections.
• Do not use RCOU1A, RCOS1A, REMU1A (two-wire), RDDU1A, RGLU1A, or RGLU2A
analog CO line interfaces in IP telephone applications. These PCBs will work, but will cause IP
telephone users to experience unacceptable voice quality and echo return loss.

Power Over LAN
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 18, with software revision
6805 or later, are compatible with the Toshiba IPT1020-SD. AC and AC/DC models are available.

IP Telephony

Toshiba IP Soft Phone
The Toshiba IP Soft Phone will be available in a future release. The Toshiba IP Soft Phone is an IP
telephony client that works with a wired or wireless (Wi-Fi) desktop or laptop PC or Pocket PC.
The Toshiba IP Soft Phone integrates the power of a PC with all of the features available on a
DKT3000-series telephone, except background music.
With the Toshiba IP Soft Phone installed on a Wi-Fi Pocket PC or laptop PC, users can have true
mobility with access to voice mail, programmable feature buttons, and a directory that works with
Microsoft® Outlook® 2002. Users can access the Internet on the same Pocket or laptop PC that
has the Toshiba IP Soft Phone.
IP Soft Phone operation requires a wired or wireless connection over the IP network (Internet,
WAN, LAN, etc.) to the CTX BIPU-M2A IP interface. The voice communications uses the
MEGACO+ protocol for call control signaling and RTP for voice transmission.
The Toshiba Soft Phone works on the following:
• Desktop or laptop PC with Windows XP, or higher,
operating software (OS)
• Toshiba Pocket PC e750 series with Windows Pocket PC
2003
The Toshiba IP Soft Phone operates much the same as a
Toshiba Digital 3000-series telephone (see Figures 13 and 14).
A mouse or stylus is used to click or select the buttons. The
&DOO button operates the same as the DKT3000-series
telephone 6SNU button. Additionally, there are six feature
buttons that can be customized from telephone programming
mode.

Features
Private Networking Over Internet Protocol

Private Networking Over Internet Protocol
Strata Net CTX multi-system networking can be implemented over an IP network using Strata
CTX systems with BIPU-Q1A IP interface PCBs. 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 (see “Strata Net Multi-system Networking” on page 78 for more
information). QSIG over IP does not support data calls (modem signal and G3 FAX).
The BIPU-Q1A can be configured for 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.
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

Features
Integrated Services Digital Network (ISDN)

Integrated Services Digital Network (ISDN)
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
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 PCB 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)
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 /LQH (or
&2/LQH) buttons. (For information on various [DN] buttons, refer to “Directory Numbers” on
page 55.) The Strata CTX supports the following types of line buttons:

CO Line Buttons
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.

Strata CTX General Description

06/03

Features
Live System Programming

Pooled CO Line Button
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
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
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
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
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.
The telephone main 0VJ 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 '1' button LED on their telephone. (See Table 32 on page 94 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.

Features
Microphone (External Unit)

Microphone (External Unit)
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
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
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.

Off-Hook Call Announce (OCA)
Station users may announce a call when the station they call is busy talking with the handset offhook. 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 PCB 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 0VJ button (toggle) to place the original call on hold or holding
down the 0LF 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.

Strata CTX General Description

06/03

Features
Off-Premise Stations

Off-Premise Stations
Off-premise stations are supported using either standard analog telephones or Toshiba digital
telephones. This can accommodate both individual telephones and branch office connections. Offsite 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.

Override
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
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
3ULYDF\ button does not block Executive Override.

Strata CTX General Description

06/03

Features
Paging

Privacy Override
Privacy override controls the ability of multiple station users with a shared (common) /LQH 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 /LQH 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
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 to 32 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 PCBs can be installed to connect external paging or night
ringing equipment. Each BIOU supports up to four page zones.

Strata CTX General Description

06/03

Features
Power Failure Protection

Power Failure Protection
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
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
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 3ULYDF\5HOHDVH button.

Repeat Last Number Dialed
This feature enables a digital station to automatically redial the last number dialed from their
station by selecting an outgoing line and pressing the 5HGLDO button or by dialing an access code.
Digital key telephones have a fixed 5HGLDO button for automatic redialing of the last number
dialed.

Strata CTX General Description

06/03

Features
Ringing

Ringing
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 to cause the idle [DN] to Ring Over Busy.

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 52.

Distinctive Ringing
See “Distinctive Ringing” on page 56.

Speed Dial
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 6SGLDO 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

Station Hunting

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 () plus a
zone number () 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.
Multiple feature buttons such a &QI?7UQ, [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
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.

Features
Station Message Detail Recording (SMDR)

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.

Station Message Detail Recording (SMDR)
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 PCB and a connected Call Accounting system.

Strata Net Multi-system Networking
Strata Net is a private networking application based on QSIG, an international standard for the
interconnection of PBX. Strata Net delivers a rich set of calling features across multiple Strata
CTX systems distributed throughout the enterprise. Users benefit from transparent dialing and
simple feature operation.
Advanced networking features include Centralized Voice Mail, Centralized Attendant and Station
DSS button appearances across all nodes. Network Station Message Detail Reporting (SMDR).
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 interconnectivity. 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.

Coordinated Numbering Plan
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.

Strata CTX General Description

Features
Strata Net Multi-system Networking

QSIG Basic Call Control
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.

Alternate Routing
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
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
With Release 1.3 and higher, 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
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
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

System Fault Finding and Diagnostics
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 and attendant consoles.

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

Backup/Restore
The customer database can be backed up and restored using the SmartMedia card. The customer
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
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.

Strata CTX General Description

06/03

Features
User Programming Mode

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 84.

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.

User Programming Mode
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 3URJUDP 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 %*0 button.
• Ring tones – /LQH 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.

Strata CTX General Description

Features
Voice or Tone Signaling

Voice or Tone Signaling
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 . The signaling method can also be switched from Tone to Voice Signaling by dialing
. Whether a call is initiated with Tone or Voice Signaling, it can always be switched back and
forth by dialing or .
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
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.

Strata CTX General Description

Features
Volume Control

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 5HFRUG on the digital telephone. To end the recording, they can press
5HFRUG again. Station users can also stop and start recording by pressing 365(6.
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 5HFRUG is pressed or dialed after 5HFRUG 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

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 'LUHFW7UDQVIHUWR90 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
Digital Telephone users can independently adjust their handset hearing volume, speaker hearing
volume including BGM, speaker incoming tone volume and beep tone volume.
