Toshiba Strata Dk14, Dk40i, Dk424i General Description Manual

							Strata DK General Description    6/0065
System Features6
This chapter describes system features for the DK14, DK40i and DK424i, in alphabetical order. 
These features are available on a system-wide basis and apply to all of these systems, except where 
noted. See Table 38 on Page 95 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. Stations can be 
programmed to store from 0 to 100 abandoned call numbers in increments of 10.

DK14 and DK40i can store up to 200 ANI and Caller ID abandoned call numbers

DK424i can store up to 2,000 ANI and Caller ID abandoned call numbers
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.
Alarm Sensor (DK40i, DK424i 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 

 button can turn off the 
alert tone. 
						

							System Features
Alternate Answer Point
66Strata DK General Description    6/00
Alternate Answer Point
Users can answer a transferred outside line call from any station that has the  button or a 
Secondary [DN] for the destination station.
Amplified Conference Interface (DK40i, DK424i only)
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 
(DK424i) amplifiers per system can automatically connect to any two CO line conference. This 
feature is available for the Strata DK40i and  DK424i.
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), 
KKYS1~3 (DK40i), RKYS1~3 (DK424i).
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 BRCS (DK424i) 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

DK424i each enable up to 24 caller connections
Auto Attendant is licensed by Dytel, Inc. under United States Patent No. 4,975,941.  
						

							System Features
Automatic Call Distribution (ACD)
Strata DK General Description    6/0067
Automatic Call Distribution (ACD)
An optional feature upgrade key (KKYS2 or KKYS3 on the DK40i, Release 4.3, or RKYS2 or 
RKYS3 on the DK424i) connected to the processor enables ACD group features. Thus, 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. 
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 KKYS3 and 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
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 2000, 98, 95 (Vers. 4.00.950A, B, or C), or Windows NT
® with a minimum Service Pack 
3 installed.
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 DK Call Center Solutions General Description for more 
information.
ACD Feature capacities are listed in Ta b l e  3 3.

							System Features
Automatic Number Identification (ANI)
68Strata DK General Description    6/00
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; BRCS for DK424i) is required for ANI line operation. DK14 does not 
support ANI.
ANI is also known as Calling Number Identification Service (CNIS) on ISDN lines. CNIS 
operates the same as ANI on the DK424i. 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, DK424i only)” on Page 72 and Ta b l e  3 4).
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 72).
Refer to the sections on ANI, Caller ID, DNIS or DID and Table 34 for more specific routing 
information.

							System Features
Automatic Release from Hold
Strata DK General Description    6/0069
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. 
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 processor 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 
 while the call is ringing to alternate between DNIS and ANI/Caller ID LCD displays. 
See “Computer Telephony Integration (CTI)” on Page 70 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 34).

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. 

DK424i – 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.  
						

							System Features
Centrex/PBX Compatible
70Strata DK General Description    6/00
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.
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, and is compatible with Windows 2000, 98, 
95, and Windows NT.
StrataLink software greatly enhances the use of the basic TAPI interface, enabling you to 
customize the call-control functions of your PC application, including: 
						

							System Features
Conferencing
Strata DK General Description    6/0071

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.

Enhance outbound calling – StrataLink provides for outbound telephone calling and call 
control from the PC application.

Easy setup, testing, and monitoring – StrataLink provides tools for testing the interface, 
debugging or monitoring the call events, and makes application setup easier. When you select 
from pre-defined tested applications, the proper interface is automatically assigned.
Conferencing
A variety of Conferencing combinations are available to all station users, as listed below. Stations 
and lines can be added in any order. (See “Amplified Conference Interface (DK40i, DK424i only)” 
on Page 66)

One or two stations and two outside lines

Two or three stations and one outside line

Four stations on one internal [DN] line
Credit Card Calling
Callers can make credit card calls (0 + telephone number + credit card number) that bypass Toll 
Restriction. The calls are billed to the credit card, not to the Strata DK line. The system requires 
that a specific quantity of digits be dialed; otherwise, the call will be dropped within 20 seconds to 
prevent operator-placed calls that would be billed to the Strata DK line.
Data Switching
Strata DK offers a sophisticated optional data switching capability using PDIU-DS and RPCI-DI 
that can interconnect a wide range of customer-supplied data equipment, including PCs, printers, 
and modems. Asynchronous data can be transmitted between devices connected to PDIU-DS/
RPCI-DI at speeds up to 19.2 kbps (see Table 40 on Page 109).
The system provides four data security groups to restrict data calls between groups. Dialing by PC 
(both data and voice calls) as well as modem pooling and printer sharing is supported. 
						

							System Features
Day/Night Modes
72Strata DK General Description    6/00
Day/Night Modes
The system has three available ringing modes for routing incoming line calls. The routing 
destinations are [DNs], ACD groups, Distributed Hunt groups, Auto Attendant, DISA, and a night 
bell. The ringing modes are Day, Day2, and Night.
Each mode can be assigned a distinct ringing destination. The system can be programmed with 
either two modes (Day, Night) or three modes (Day, Day 2, Night), which can be changed by any 
station programmed with a 
#(
 button. A supervisor’s #( button can be 
provided to prevent false changes in modes. Day/Night call routing applies to all incoming line 
types: ANI, DNIS, Caller ID, DISA, Tie, and DID lines.
Delayed Ringing
If an incoming CO, DID or Tie line or internal [DN] call rings a station [DN] and is unanswered, 
alternate stations can be programmed to ring 12 or 24 seconds later. The stations that were ringing 
initially will continue to ring after the Delayed Ringing begins. This feature is assigned on a line-
by-line and [DN] basis. 
It is also possible to direct loop or ground start CO line calls to the Strata DK built-in AA on a 
delayed ring basis. In this case, the telephone(s) that initially ring will stop ringing when the AA 
answers.
Dialed Number Identification Service (DNIS)
(DK40i, DK424i only)
This feature enables incoming DNIS (called party) telephone numbers to display on the LCDs of 
ringing telephones. DNIS is provided on analog, and/or digital (T1, ISDN PRI/BRI), DID and Tie 
lines. An optional DTMF tone receiver PCB is required for DNIS.
Normally, DNIS is associated with “1-800” type calls offered by various long distance carriers; 
however, the Strata DK can provide DNIS information over DID and Tie line circuits.
Traditionally, each 800-number is assigned to its own line group, often resulting in a large number 
of under-used lines. DNIS allows multiple numbers to ring into the same line or line group, which 
provides a more efficient use of 800-numbers. Each DNIS line is used on an as-needed basis for 
different 800-number calls.

DK40i supports up to 200 DNIS numbers and a maximum of 100 telephone network numbers. 
The K5RCU (DK40i) optional tone receiver PCB is required for DNIS. Each DNIS, DID or 
Tie line reduces the station capacity by one.

DK424i each support up to 500 DNIS numbers and a maximum of 300 telephone network 
numbers. BRCS optional tone receiver PCB is required for DNIS. See “Station Features by 
Station Type” on Page 110.
The DNIS numbers are correlated in the system database with assigned DNIS names. DNIS names 
(up to 16 alphanumeric characters) display on direct incoming, transferred, and Call Forward calls. 
This allows incoming calls to be identified and answered appropriately.
DNIS numbers can be assigned to ring unique destinations in the Day, Day2, and Night Ring 
modes (Table 34). The DNIS (called number) digits can be received independently or 
simultaneously with ANI “calling number” digits (see “Automatic Number Identification (ANI)” 
on Page 68).  
						

							System Features
Direct Inward Dialing (DID) Lines (DK40i, DK424i only)
Strata DK General Description    6/0073
Priority of ANI or DNIS is set for each line in system programming. DNIS digits can also be sent 
to a PC. See “Computer Telephony Integration (CTI)” on Page 70.
External Telephone Network Numbers
All DNIS/DID/Tie numbers that ring into the Strata DK can be routed externally to any outside 
telephone number. Depending on the application, the caller DNIS name may be passed to the 
destination Strata DK when routed over the telephone network.
Voice Mail
If assigned in the system database, incoming calls for each unique DNIS/DID/Tie number can be 
directly routed or Call Forwarded to a designated voice mailbox. This allows callers of each DNIS/
DID/Tie number to receive immediate personal custom greetings.
NoteThis feature is available on in-band integration only. It is not available using SMDI.
Direct Inward Dialing (DID) Lines (DK40i, DK424i only)
Based on the final digits of a dialed telephone number, DID enables incoming calls over a single 
line to directly ring one or a number of stations which share a common [DN]. DID numbers can be 
assigned to ring a number of destinations (see Ta b l e  3 4). DK14 does not support DID.
DID is provided by analog or digital (T1, ISDN PRI/BRI) lines. The TDDU and RDDU analog 
PCBs support DID. For the DK424i only, the digital T1/DS-1 (RDTU2) or ISDN PRI (RPTU) 
PCBs support DID. 
Each DID number can be assigned a Name to display on an LCD telephone that rings when the 
DID number is called. Each DID line has a single office code and a block of extension numbers 
(the final digits) that can be individually assigned in system programming to ring stations.
DID lines can directly access the remote maintenance modem and can optionally provide 
automatic Camp-on-busy when callers dial a busy [DN] on incoming DID calls. This feature 
provides a camp-on tone and distinctive LED flash at the busy station.

DK40i and DK424i – DID lines do not affect station port capacity. 
An optional tone receiver PCB (K5RCU or BRCS) is required for DID line DTMF operation.
Direct Inward System Access (DISA)
Outside callers using a DTMF-capable telephone can dial internal stations or outgoing lines 
directly, without going through a receptionist or operator. DISA security codes and/or a verified 
account codes, each up to 15 digits, can be assigned to prevent undesired access to lines.
DISA is available to any quantity of ground or loop start lines (not Tie or DID), either directly or 
through the Strata DK built-in AA. It enables privileged users to take advantage of the benefits of 
the Strata DK even when they are not on the premises. An optional tone receiver PCB (QRCU3, 
K5RCU or BRCS) is required for DISA.
DISA can be accessed by calling into the DK built-in AA. To prevent users from calling into the 
Auto Attendant and accessing an outgoing line with DISA to make unauthorized external calls, be 
sure to use the DISA security code. 
						

							System Features
Distinctive CO Line/Directory Number Ringing
74Strata DK General Description    6/00
Distinctive CO Line/Directory Number Ringing
The incoming line ringing tone to digital telephones is distinct from the internal ringing tone 
indicating the type of the call. This feature is optional for standard telephones by using a different 
ring pattern.
Door Lock Control
Digital and electronic telephone station users can unlock a customer-supplied electronic door lock 
at the touch of an optional button on their telephone. 

DK14 supports up to two locks

DK40i supports up to three locks

DK424i supports up to five locks
Door Phones (MDFB)
Door phones are frequently mounted near building entrances and associated with a customer-
provided door lock to help screen visitors. Door phones can be assigned to ring [PDNs] and/or 
[PhDNs]. Each door phone must be connected to a DDCB or HDCB.
They also monitor sound—station users can call the door phone and listen to sounds from the 
surrounding area. In a warehouse-type environment, a door phone can work as a “hot link,” for 
example, the door phone can have a preassigned button that accesses a certain telephone [DN] in 
an office, and any common [DNs]. 

DK14 supports up to six door phones

DK40i supports up to nine door phones

DK424i each support up to 12 door phones
DTMF Back Tone
The system can be programmed to allow or prevent 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 Compatible
The Strata DK System works with either DTMF or rotary dial pulse CO lines on a line-by-line 
basis.
DTMF Signal Time (80/160 ms)
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. The time can be set independently for line out-dialing and for 
voice mail automatic dialing. See “Continuous Dual-tone Multi-frequency (DTMF) Tone” on Page 
102.
