Various telephone and system parameters can be changed from the console, without a separate 
maintenance port. These include Telephone User Names and System Speed Dial numbers.
The PCATT provides a Name/Number search that works with automatic or manual call handling. 
Other powerful features for the PCATT include Call Answer Priority and Queuing, Direct Station 
Selection, dial pad DTMF signaling, Emergency Call ID, Flexible Programmable Keys, Loop 
Keys with Status Indication, keyboard or mouse operation, and headset or handset operation with 
volume control. See “PC Attendant Console Features” on Page 102 for feature descriptions and 
Table 36 on Page 108 for a list of features.
Direct Station Selection (DSS) Console
The DSS consoles are for system operators.
They operate alongside a digital or electronic 
telephone and have 60 buttons which can be 
programmed for DSS, CO line access, All Call 
Page, Night Transfer, and Station or System Speed 
Dial. DSS consoles do not have their own [DNs], 
since they are connected to a telephone.
 Multiple consoles can operate with one DKT:
©DK14 does not support DSS consoles
©DK40i supports up to three consoles
©DK424 supports up to eight consoles (Table 34 
on Page 89 for DK424 DSS console capacities 
for various common control units)
The DSS console uses LEDs to indicate call and feature status; the DDSS has dual red and green 
LEDs to help further define status. The DDSS console connects to the PDKU2. For details on data 
interface specifications (Table 43 on Page 116). The older electronic HDSS console is also 
supported.
Door Phone (MDFB)
MDFBs are often used with a door lock to screen 
building visitors. Door phones also can operate as a 
“hot line.” For example, a door phone can be used 
for calls between an office and a warehouse 
(requires DDCB).
©DK14 can have up to 6 door phones
©DK40i can have up to 9 door phones
©DK424 can have up to 12 door phones (see 
Table 34 on Page 89 for MDFB capacities for various common control units)

Toshiba Stratagy and Stratagy DK Processing
The Strata DK can operate with Toshiba Stratagy and Stratagy DK voice processing systems, 
which provide a number of helpful features.
The DK14, DK40i and DK424 also support SMDI voice mail integration (see “Simplified 
Message Desk Interface (SMDI)” on Page 80). Refer to the appropriate Stratagy literature for 
details. For Stratagy voice mail processors, a standard telephone PCB is also required (QSTU2, 
KSTU2, RDSU, RSTU2).
The Strata DK supports in-band DTMF voice mail integration for all of the above voice mail 
systems and requires DTMF receivers:
©DK14 requires the QRCU3 for DTMF voice mail integration.
©DK40i requires the DK40i Expansion KSU for Stratagy DK voice mail. The K5RCU3 is 
required for DTMF voice mail integration. The Stratagy DK does not require a KSTU2, 
RDSU or RSTU2; it acts as an RSTU2 in the Strata DK KSU slot.
©DK424 requires the RRCS for DTMF voice mail integration. 
						

							Stations and Peripherals
Cabling and Connectors
60Strata DK General Description     5/99
Cabling and Connectors
Strata DK uses industry standard cabling and connectors to interface with lines, stations, and 
peripherals (Table 39 on Page 112).
Stations use standard twisted-pair cabling to connect to the system via the MDF. Digital and 
standard telephones require just one pair-cabling, or two pair, if equipped with DADM, RPCI or 
DVSU. Electronic telephones need two-pair cabling or three-pair for Speaker OCA. 
Station PCBs connect to stations and peripherals with a 25-pair Amphenol connector via the MDF. 
CO, DID, and Tie line circuits interface with the public telephone network via modular connectors.
Peripheral devices such as SMDR, DKAdmin maintenance PC, etc., are connected to the interface 
PCBs (TSIU, RSIU, PIOU, etc.) with three-pair (six wires) modular cords and the Toshiba PPTC9 
or PPTC RS-232-to-modular adapters.
The Strata AirLink Wireless Telephone system configured to standard ports (RSTU2) connects to 
all Strata DK systems using the Base Station Interface Adapters (BSIAs) and one or two Base 
Stations.
The Strata AirLink Wireless Telephone system configured to digital ports interfaces to the DK40i 
and DK424 (standard cabling and connectors) using the proprietary RWIU PCB. The RWIU uses 
industry standard RJ11 jacks to support up to four Base Stations. Multiple RWIUs can be installed 
to increase the capacity of the wireless system.

DK424, in alphabetical order. These features apply to all of these systems, except where noted.
This chapter includes these sections:
©System Features
©Station Features
©PC Attendant Console Features (DK424 only)
System Features
This section describes features that are available on a system-wide basis. See Table 32 on Page 88 
for a list of system features.
Abandoned Call Numbers
Automatic Number Identification (ANI) and Caller ID calls that ring but are abandoned before 
they are answered can be stored in system memory. LCD telephone and attendant console users 
can display and Auto Dial the “abandoned call” ANI and Caller ID numbers. 
©DK14
 and DK40i
 can store up to 200 ANI and Caller ID abandoned call numbers
©DK424
 can store up to 2,000 ANI and Caller ID abandoned call numbers
For DK14/DK40i/DK424, stations can be programmed to store from 0 to 100 abandoned call 
numbers in increments of 10.
Account Codes (Forced/Voluntary/Verified)
Account Codes provide a method of tracing and categorizing CO line calls on the SMDR report. 
They may even be used to temporarily change a restricted stations class of service to allow long 
distance calling after an Account Code is entered. 
Account Codes may be required before dialing calls (Forced) or optionally entered during calls 
(Voluntary). Codes can be as long as 15 digits and can be verified or nonverified. If a printer is 
connected to the system, a record of each Account Code prints out on the SMDR report.
NoteThe 911 emergency number and two other optional customer-designated numbers (up to 
four digits long) can be assigned to bypass Forced Verified Account Code requirements.

62Strata DK General Description    5/99
Alarm Sensor (DK40i and DK424 only)
Both the PIOU and PIOUS option interface PCBs have a sensor that can be connected to a 
customer-supplied alarm system. If the alarm is activated, the sensor triggers a loud alert tone to all 
digital and electronic telephones. Any station programmed with an 
$ODUP button can turn off the 
alert tone.
Alternate Answer Point
Users can answer a transferred outside line call from any station that has the /LQH button or a 
Secondary [DN] for the destination station.
Amplified Conference Interface
Provides interface for a customer-supplied amplifier to improve low volume levels due to losses 
on some CO lines. The amplifier is not dedicated to certain CO lines (it is shared by all CO lines) 
and automatically connects to calls that include two CO lines: for example, DISA, conferencing 
and external call forward.
This amplifier provides a louder sound level on these types of calls and requires two circuits on a 
PEKU or PESU PCB installed in the Strata DK per amplifier. A maximum of two (DK40i) or four 
(DK424) amplifiers per system can automatically connect to any two CO line conference. This 
feature is available for the Strata DK40i and DK424.
Auto Attendant (Built-in)
The built-in AA feature acts as an operator that automatically directs incoming calls to stations. 
Strata DK provides a built-in AA feature via optional feature upgrade keys: QKYS (DK14), 
KKYS (DK40i), RKYS1~3 (DK424).
Callers who dial in to assigned Strata DK AA lines can receive a dialing prompt menu, such as, 
“Dial 5 for Sales, dial 6 for Tech Support.” When the caller dials the digit, the call routes to a 
[DN], ACD group, or Distributed Hunt group (assigned in system programming). 
AA can be programmed to answer CO line calls immediately or with a delayed ring option. AA 
can pick up unanswered calls that ring for either 12 or 24 seconds at selected stations. An 
unlimited number of CO lines can be assigned for built-in AA. Built-in AA applies to loop and 
ground start CO lines only; it does not answer Tie or DID line calls.
Built-in AA enables access to outgoing lines via DISA, which should be security protected with 
account codes and/or a DISA security code.
The AA feature requires customer-provided digital announcement device(s) and optional QRCU3 
(DK14), K5RCU (DK40i) or RRCS (DK424) tone receiver PCBs. Callers can be connected to one 
digital announcer simultaneously. One DTMF receiver is needed per caller.
©DK14 enables up to three caller connections
©DK40i enables up to five caller connections
©DK424 allows up to 24 caller connections
Auto Attendant is licensed by Dytel, Inc. under United States Patent No. 4,975,941. 
Automatic Call Distribution (ACD) (DK424 only)
With an optional feature upgrade key (RKYS2~3) connected to an RCTU processor, stations in the 
DK424 can be arranged in ACD groups. Such an arrangement enables incoming calls over a CO 
line to be distributed among a group of ACD Agents. This is ideal where a number of staff 
members receive the same type of calls, since calls can be automatically distributed.  
						

							Features
System Features
Strata DK General Description    5/9963
Incoming calls that are not directly connected to Agents wait in queue for the first available Agent 
in the called group. While waiting, callers hear programmed announcements and music at 
designated intervals to encourage them to remain on hold. This feature requires a customer-
provided, digital announcement device(s) and music source. 
When the number of ACD calls waiting in queue reaches a programmable threshold, calls can 
overflow to another ACD group or destination such as a Distributed Hunt (DH) group.
The ACD feature also enables supervisor stations to provide ACD Agents with call assistance and 
call monitoring. ACD Supervisor LCD telephones can display ACD group status, individual Agent 
status (available/unavailable, on an ACD call, etc.) and Call Status (the number of calls in queue, 
longest call in queue, etc.).
Additionally, the RKYS3 feature key enables the use of a Call Center Viewer, SMIS, or Insight 
DK application. SMIS provides detailed supervisory monitoring of Agent calls (on a PC screen) 
and printed reports regarding an Agent’s performance. Call Center Viewer presents real-time ACD 
Agent and Queue Status to multiple PC screens.
Insight DK (DK424 only)
The Insight DK and Insight DK Plus systems are full-featured ACD MIS tools for call center 
supervisors, providing user-defined supervisor displays, user-defined historical reports, electronic 
wall board connections, and inView LAN-based status display messaging.
Insight DK and DK Plus are Windows-based MIS software programs that work with PCs running 
Windows 95 (Vers. 4.00.950A, B, or C), Windows 98 or Windows NT
® with Service Pack 3. 
They both support external wallboard displays and scheduled reporting. The data collected can be 
exported for further processing using other report generator programs or spread sheets. They also 
support inView, which provides LAN-based status displays in a wallboard format on Agent’s or 
Supervisor’s PC screens. See the Strata DK424 Call Center Solutions General Description
 for 
more information.
ACD Feature capacities are listed in Ta b l e  2 8.
Table 28 ACD Capacities
Automatic Number Identification (ANI)
LCD telephones can display the telephone number of the calling party for direct, incoming, 
transferred, and Call Forwarded calls. The telephone number can also be sent to an application 
computer or to voice mail.
The system supports ANI on analog or digital lines (T1 or ISDN PRI/BRI), DID and Tie lines, and 
provides the calling telephone number to answering parties. An optional tone receiver PCB 
(K5RCU for DK40i; RRCS for DK424) is required for ANI line operation. DK14 does not support 
ANI.

64Strata DK General Description    5/99
ANI is also known as Calling Number Identification Service (CNIS) on ISDN lines. CNIS 
operates the same as ANI on the DK424. ANI digits can be received independently or 
simultaneously with DNIS called number digits. 
Calls received with DNIS digits can be routed to unique destinations for each DNIS number (see 
“Dialed Number Identification Service (DNIS) (DK40i and DK424 only)” on Page 68 and 
Table 29).
If ANI is received without DNIS, all ANI calls ring the same selected destination. ANI calls are 
calls can be routed to a unique destination for each system ringing mode (Day, Day 2, Night). All 
routing destinations except Intercept can be assigned by system programming to change according 
to the time of day (see “Day/Night Modes” on Page 67).
In the DK40i, each ANI line reduces station capacity by one. ANI (DID or Tie) lines do not reduce 
the station capacity in DK424 systems, Release 4.0. 
Refer to the sections on ANI, Caller ID, DNIS or DID and Table 29 for more specific routing 
information.
Automatic Release from Hold
If an outside caller on hold hangs up, the system will automatically disconnect the call and free the 
line for other calls. This feature applies to DISA, DNIS and/or ANI external routed calls, AA, 
voice mail calls, and regular voice calls. 
Automatic Release is available on a line-by-line basis and operates only with COs that provide a 
disconnect (Calling Party Control) signal. 
Background Music (BGM)
BGM can be sent to telephone and external speakers. The customer-supplied BGM source(s) can 
be applied in a flexible manner.

Strata DK General Description    5/9965
One music source can feed both types of speakers, or both types can have their own separate 
source. The source used for MOH can also be piped to telephone speakers for BGM or an alternate 
BGM source can be connected so callers on-hold have a separate music/announcement source. 
The BGM source connects to the RCA jack in the system’s Base Cabinet, RCTU, or to a 
designated standard or electronic telephone circuit port.
Caller ID
This feature enables the telephone number or name of the calling party to display on the ringing 
telephone’s LCD. It can also be sent to an application computer or to voice mail. Up to 10 digits or 
16 characters can be displayed or sent to a computer. 
Caller ID (CLID) information displays on direct, incoming, transferred, and Call Forwarded calls. 
For PCs, CLID allows both the caller’s name and number to be sent. If the Strata DK system is 
programmed to receive both ANI and DNIS information on incoming calls, the station user can 
press 
3DJH while the call is ringing to alternate between DNIS and ANI/Caller ID LCD displays. 
See Computer Telephony Integration (CTI) on Page 66 for more information.
Caller ID is similar to ANI except that Caller ID is offered by local carriers on ground or loop start 
lines. Most local carriers charge an extra fee for this service.
A Caller ID Interface PCB is required, in conjunction with the normal ground or loop start CO line 
PCBs, to provide the Caller ID feature. 
Caller ID can be provided only on analog loop start lines (with QCDU2, KCDU2, TCOU, RCOU 
or RCOU/RCOS) and analog ground start lines (RGLU2). It is not available on any other type of 
analog lines (TDDU, RDDU and/or REMU) or any type of T1 or ISDN digital lines (see Table 29).
©DK14
 – the WSIU PCB is required to provide an RS-232 interface to a customer-provided 
Caller ID interface device (TC-1041). CO lines that receive Caller ID must be cross-connected 
to the TC-1041 (MLX-41) Caller ID interface box. The TC-1041 (MLX-41) is available from 
TEL-CONTROL, Inc., P.O. Box 4087, Huntsville, AL 35815-4087. Phone (205) 881-4000.
©DK40i
 –the TCIU2, RCIU2 and RCIS PCBs come with four Caller ID circuits each. The 
TCIU2 is used for Base Cabinet lines and the RCIU2/RCIS is used for Expansion Cabinet 
lines to provide up to eight Caller ID interface circuits. A KCDU2 can also support Caller ID 
with an RCIU2. A TCIU2/RCIU2/RCIS circuit must be available for each line that is to 
receive Caller ID. 
©DK424
 – when ordered from the factory, the RCIU2 PCB comes with four Caller ID circuits; 
however, an RCIS piggy-back PCB can be installed on the RCIU2 to provide four more Caller 
ID circuits, for a maximum of eight Caller ID circuits per cabinet slot. An RCIU2/RCIS circuit 
must be available for each line that is to receive Caller ID.
ANI is delivered by long distance providers on DID or Tie lines. 
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 four-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.

System Features
66Strata DK General Description    5/99
Computer Telephony Integration (CTI)
CTI combines the capabilities of the Strata DK digital business telephone system with custom 
functionality provided by computer applications. This can be provided through the Digital 
Telephone Integrated PC Interface.
Digital Telephone Integrated PC Interface
A Toshiba 2000-series digital telephone can be connected to a PC. This can be used for both 
routine data switching simultaneous voice and data applications, and for more robust CTI 
applications.
The connection is made with an RS-232 cable from a communication port on a PC to an RS-232 
port on the digital telephone. The RS-232 port is provided by equipping the digital telephone with 
an integrated PC Interface Unit (RPCI-DI). This optional unit replaces the normal telephone base 
and equips the telephone for simultaneous computer-telephone interface and voice/data features.
Data switching applications enable users to make data calls to printers, PCs, and other data 
devices. Users can also make voice calls using PC directory dialing software, without the need for 
a modem or an additional outgoing line. 
The system can be programmed with one to four security groups, and can restrict calls between 
groups. It can also support modem pooling and printer sharing.
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 DK 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 DK system, Caller ID, ANI, DNIS and call processing information can be passed 
from the digital telephone to the application computer.
StrataLink
The Strata DK can interface with computer applications that conform to Microsoft Windows TAPI 
format. The Toshiba StrataLink Telephony Service Provider Interface (TSPI) software enables the 
Strata DK to communicate with TAPI applications. StrataLink TSPI software is bundled with the 
RPCI-DI in the form of a 3-1/2” IBM-compatible disk.
StrataLink software greatly enhances the use of the basic TAPI interface, enabling you to 
customize the call-control functions of your PC application, including: 
©Select how the PC application responds to the next call event – StrataLink can accept call 
events from the telephone, apply call handling rules and conditions, and invoke actions in a PC 
application.
©Handle multiple telephone calls – Most TAPI compatible applications can only handle one 
call at a time because they only respond to a ringing line for Caller ID database lookup and 
screen display. StrataLink enables the application to respond to multiple calls and events that 
capture Caller ID and generate screen displays. It also displays transferred calls and 
reconnections to held calls. The display can be delayed until after the current call or for a 
programmed amount of time.
©Handle multiple PC applications from the same telephone – Incoming calls can activate 
actions in different applications, depending upon the type of call.
For example, you can generate “customer database” application screens of callers on your 
regular directory numbers, use “help desk” application software generated from ACD calls, 
and have your pager beep with Caller ID when you are away from your desk. Different 
applications can be assigned to work on specific buttons on your telephone, or on all buttons.
