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 
+ , [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.

Station Message Detail Recording (SMDR)
78Strata CTX General Description    06/03
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 inter- 
connectivity. DS1 circuits may be leased from public carriers, derived from Frame Relay or IP 
networks, or connected across twisted-pair cabling or fiber optics. 
QSIG over IP also provides full Strata Net connectivity and capabilities over an IP network (VPN 
WAN, Internet or intranet). 
Up to 128 nodes can be accommodated within the Strata Net numbering plan. Up to four nodes 
connected in tandem can give satisfactory performance with regard to latency. As with any 
network design, transport, delay speech volume and other issues must be carefully considered.
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 Net Multi-system Networking
Strata CTX General Description    06/0379
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.

System Fault Finding and Diagnostics
80Strata CTX General Description    06/03
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
Tr a n s f e r
Strata CTX General Description    06/0381
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. 
						

							Features
User Programming Mode
82Strata CTX General Description    06/03
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 

, 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 
-. button.
Ring tones –  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.
NoteDirectory number and external line buttons cannot be added or deleted, but their ring tones 
can be individually changed.
In addition to the Programming Mode, an advanced programming function enables administrators 
to individually turn On/Off the telephone’s beep tone, handset call waiting tone, and microphone 
background noise cancellation option. This mode enables LCD contrast adjustment and testing the 
DKT3014 large LCD screen. 
						

							Features
Voice or Tone Signaling
Strata CTX General Description    06/0383
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 /.
NoteA 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. 
						

							Features
Volume Control
84Strata CTX General Description    06/03
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 

 on the digital telephone. To end the recording, they can press 

 again. Station users can also stop and start recording by pressing 
0
. 
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 

 is pressed or dialed after 
 is pressed.
Recording to Voice Mail (VM) is available on two-party and multi-party conference calls.
Voice Mail Soft Keys (Stratagy ES/iES32 Only)
Voice Mail Soft Keys provide LCD telephone 
users with an active set of Soft Keys that prompt 
the user with available commands to play Voice 
Mail messages and to manage their mail boxes 
(shown right).
The LCD shows the number of New and Saved 
messages in the user’s mailbox.
The number of New/Saved messages displays on 
the LCD when the telephone is idle and has at least 
one new message.
Soft Keys requires the Toshiba Proprietary VM 
integration and connection to the Strata CTX LAN.
Direct Transfer to Voice Mailbox
The transferring party can transfer a call directly to a person’s voice mailbox without waiting for 
the call to forward from the called party’s telephone. The voice mailbox does not need to be 
associated with an active telephone in the Strata CTX. Direct transfer to voice mail (VM) can be 
performed to a centralized VM system connected to a network node other than the user’s node.
The transferring party presses 

1 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.
Vo l u m e  C o n t r o l
Digital Telephone users can independently adjust their handset hearing volume, speaker hearing 
volume including BGM, speaker incoming tone volume and beep tone volume.
