Background Music (BGM) Interface
A BGM/Music-on-Hold (MOH) RCA jack is built into the common control unit on DK14, DK40i, 
and DK424 systems and connects a customer-supplied music source to the system. The music 
source or sources is flexible, providing one music source for telephone and external speakers or a 
separate source for each.
When BGM is broadcast over digital or electronic telephone speakers, no optional hardware is 
required. The customer-supplied music source for both background music on telephone speakers 
and MOH connects directly to the common control unit.
To connect BGM (separate music source) over telephone speakers, a station port should be 
assigned. The required interfaces cards are:
©DK14 – QSTU
©DK40i – KSTU, RSTU, PSTU, PEKU, or PESU
©DK424 – RSTU, RDSU, PSTU, PEKU, or PESU
When a music source is connected and this feature is activated, a station user can access BGM 
through the speaker of a digital or electronic telephone. The music is turned on and off at the user’s 
option using the BGM button or a dial access code. The user can also control the volume.
On DK40i and DK424 systems, up to three separate music sources can be connected to the system 
at the same time. One source can broadcast BGM over digital or electronic telephone speakers, the 
second broadcasts over external speakers, and the third provides music or a recording for MOH. 
DK14 systems can support two separate music sources, one for MOH, and the other shared by 
DKT and external speakers.
When the source input for BGM over external speakers is unamplified, a DK40i or DK424 system 
can use the built-in, three-watt amplifier of an Option Interface Unit (PIOU or PEPU). Amplified 
music output requires the PIOU or PEPU, or the music input source must be connected through an 
external amplifier.
If an external paging system is installed, music can also be broadcast through the external paging 
speakers, providing background music throughout the facility. Music on both the external speaker 
and the telephones is muted when a paging announcement is made or when night ringing occurs.
NoteThere is an optional secondary interface.
Benefits
Provides music that is conducive to the work environment and enable employees to listen without 
the conflict that can accompany the use of radios or tape recorders.

Caller Identification (ID)  
On the DK14 system, the WSIU PCB provides 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 is available from TEL-CONTROL, Inc., 
P.O. Box 4087, Huntsville, AL 35815-4087, (205) 881-4000.
On the DK40i, the TCIU2, RCIU2 and RCIS PCBs provides 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 TCIU2/RCIU2/RCIS circuit must be available 
for each line that is to receive Caller ID.
On the DK424, the RCIU2 provides four Caller ID circuits when installed at the factory; however, 
an RCIS piggyback 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.
The telephone number or name of the calling party can be displayed on the LCD of a ringing 
telephone, Attendant Console display, and/or sent to an application computer or voice mail. The 
information is displayed on direct, incoming, transferred, and forwarded calls. The Caller ID 
information continues with the call as many times as the active call is forwarded or transferred 
within the system.
A maximum of 10 telephone number digits can be displayed or sent to a computer, and a 
maximum of 16 characters for the name. A typical Caller ID display with soft keys off is shown 
below:
If both the name and number of the caller are sent by the COs, the name, rather than number, 
appears on the top line of the LCD display. The name and number do not appear together on the 
same LCD display. However, while the call is ringing, the user can press the Page button to toggle 
the top line display from name to number and back. This enables the station user to see both the 
name and number of the caller while the telephone is ringing. If the Caller ID feature is being used 
in conjunction with a CTI application, both the name and number are sent to the TAPI application 
computer.

Strata DK Feature Description 5/9929
Caller ID, on ground or loop start lines, provides similar capabilities as ANI. However, Caller ID 
in addition to the telephone number, can also provide the name of the caller, (if provided by the 
local CO). Caller ID is a feature offered by local COs on ground or loop start lines, whereas, ANI 
is delivered by long distance providers on digital (T1) or analog DID and Tie lines.
NoteCaller ID is not available on analog DID, Tie, or digital T1 lines.
Caller ID data is routed to DNs, Distributed Hunt groups, ACD groups (DK424 only), voice mail 
devices, and external network numbers through External Call Forward for private lines only. 
Caller ID data on answered calls can be displayed on SMDR reports and routed to different 
destinations during Day, Day 2, or Night mode. 
Abandoned Call Numbers
Caller ID data is stored in system memory for calls that ring, but are abandoned before being 
answered. This gives the user the name (if provided by the local CO) and telephone number of 
caller, even if the caller did not leave a message. LCD telephone and Attendant Console users can 
display and Auto Dial the “abandoned call” numbers.
The DK424 system stores up to 2,000 abandoned calls with the RCTUE/F processor, up to 1000 
on RCTUC/D, up to 400 on RCTUBA/BB, and up to 200 on RCTUA3. DK14 and DK40i can 
store up to 200 abandoned call numbers. Individual stations can be programmed to store from 0 to 
100 of the total abandoned calls in increments of 10. A typical abandoned call display is shown 
below:
Computer Applications
For computer applications, Caller ID digits are sent to an individual PC using an Integrated PC 
Data Interface Unit (RPCI-DI). On DK424 ACD applications, the digits can also be sent to ACD 
agents using a LAN computer with system open architecture if it has the Serial Interface Unit 
(RSIU). It enables pop-up screens on the PC that provide information regarding the calling/called 
party before answering and during the call. System open architecture requires Release 3.2 or 
higher DK424 software.
Benefits
Provides instant information about the calling person. It expedites call handling by shortening the 
length of the phone call. Most of the information that the caller has to provide is already available 
to the call taker. Even abandoned call information is available, so station users know the phone 
number, even if the caller hung up without leaving a message. This provides better service to 
callers and is a big productivity boost to call takers.

Centrex/PBX Compatibility
Any Strata DK system can be installed behind a Centrex or PBX system. It can function as part of 
the Centrex or PBX system while providing its users with the Strata DK features and digital 
feature telephones.
To further enhance Strata DK compatibility with Centrex and PBX, access codes for features in the 
host system can be programmed as if they were system Speed Dial numbers. These codes can then 
be assigned to the Speed Dial button, also known as station Automatic Dialing buttons, providing 
one-button access to the CO, Centrex or PBX feature. Each CO/Centrex/PBX feature access code 
can have up to 20 digits, including pauses and flashes.
When a Strata DK system is installed behind a PBX, some or all of the CO/PBX line buttons 
function like PBX extensions. When such a PBX line button is accessed, the station user receives 
PBX dial tone, not CO dial tone. To access a CO line on the PBX, the user must dial an access 
code. For example, “9” might be dialed to get a local CO line; Tie lines to other company locations 
might be accessed by “72” or “73.”
A Strata DK system can be programmed to recognize these PBX access codes or disregard them 
on identified lines when it inspects dialed numbers for toll restriction purposes or performs other 
features such as Last Number Redial. This enables the system to continue to provide its features, 
even when calls are ultimately going out from the PBX.
Benefits
Increased cost savings to the customer because the economical Strata DK systems can be used in 
satellite locations. Users can take advantage of the Centrex and/or PBX features, the PBX 
trunking, and the PBX networking capabilities.
Strata DK systems can also be used within a PBX environment to serve a community of interest 
which needs the functionality of electronic telephone sets that may not be provided by the PBX.
Also, CO/Centrex/PBX feature buttons give users easy, one-button access to features that would 
otherwise require more complicated access procedures. Since users do not have to look up feature 
access codes, this saves time. Time wasting dialing errors can also be eliminated through the use of 
feature buttons.

Centrex Ringing Repeat
Strata DK systems can be programmed to reproduce Centrex or PBX ringing patterns, enabling the 
user to differentiate between station or CO line calls and various callback features on the Centrex 
or PBX line.
Benefits
Enables the user to hear the same on/off ringing patterns that are heard for special calling and 
callback features on CO, Centrex, or PBX lines. Users do not have to learn new ringing cadences 
and can easily differentiate between station or CO line calls or various callback features on the 
Centrex or PBX line.

Computer Telephony Integration (CTI) 
CTI combines the capabilities of the Strata DK digital business telephone system with custom 
functionality provided by computer applications. This is provided through digital telephone 
integrated PC interface. The PC must be running Microsoft Windows software.
Digital Telephone Integrated PC Interface
Toshiba 2000-series digital telephone can be connected to a PC, enabling routine simultaneous 
voice and data switching applications and 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 Personal 
Computer Interface Unit (RPCI-DI). This is an optional unit that replaces the normal telephone 
base.
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 of a 
modem or an extra outgoing line. The system can also 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 can be connected to a computer with application software 
using the TAPI to provide customized functionality. Any TAPI enabled PC software is compatible 
with Strata DK systems. The most common use of this application is a database look up and 
pop-up screens that contain calling party information. Caller ID, ANI, DNIS, and call-processing 
information is passed from the digital telephone to the application computer, providing 
information necessary for the look-up and pop-up screens.
StrataLink
The Strata DK can interface with computer applications that conform to Windows TAPI format. 
The Toshiba StrataLink Telephone Service Provider Interface (TSPI) software enables the Strata 
DK to communicate with TAPI applications. It is bundled with the RPCI-DI on a 3.5 inch, IBM-
compatible, floppy disk.
StrataLink software greatly enhances the use of the basic TAPI interface. It enables you to 
customize the call-control functions of your PC application with many value-added capabilities, 
such as:
©Selecting how the PC application responds to the next call event.
StrataLink accepts call events from the telephone, applies call handling rules and conditions, 
and causes resulting actions to take place in the PC application. You choose the rules and 
conditions to customize how your application works.
©Handling multiple telephone calls

Strata DK Feature Description 5/9933
Most TAPI compatible applications only respond to a ringing line for Caller ID database look 
up and screen display so only one call is handled at a time. StrataLink enables the application 
to respond to multiple calls and events that capture calls and when reconnecting to a held call. 
You can delay the screen display while on another call or for a programmed amount of time.
©Handling 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 a “customer database” application display of callers on your regular DNs
©Use “help desk” application software generated from ACD calls
©Beep your pager with Caller ID when you are away from your desk
©Assign different applications to work on specific buttons on your telephone, or on all 
buttons
©Enhancing outbound calling
StrataLink provides for outbound telephone calling and call control from the PC application.
©Setting up, testing, and monitoring are easy
StrataLink provides tools for testing the interface, debugging or monitoring the call events, 
and setting up. Simply select from predefined tested applications and the proper interface is 
automatically assigned.
Figure 1 is an example of the TAPI interface that connects the digital telephone to the PC in a 
desktop integration application example. This is used when the database information resides in the 
individual PC.

Benefits
Provides custom functionality for business telephone systems by combining the two technologies. 
Users gain functionality that cannot be provided by the telephone or the computer by themselves. 
Simultaneous voice and data transmission over a single-wire pair eliminates additional wiring 
requirements and minimizes port usage on the system. For example, modem pooling and printer 
sharing enables multiple users to maximize efficient usage of expensive peripheral devices.
PC keyboard dialing of data or voice calls increases user efficiency. Auto dialing by name from 
directories stored in PCs equipped with inexpensive desk organizer-type software (modem not 
required) is an example. Data security groups control who is authorized to make outside data calls, 
which can get expensive if linked to databases which charge for access.

Conferencing
Conferencing enables other people to join your conversation. These additional people can be 
inside or outside the DK system. Any digital or standard telephone can set up conferencing with 
other digital or standard telephones. The following combinations are available:
©One or two stations and two outside lines
©Two or three stations and one outside line
©Four stations on one internal DN line
©Voice mail plus one station and two other internal or outside line parties (DK424 only)
NoteAmplified conference is available on DK40i and DK424 systems, but unavailable on the 
DK14.
System-wide programming enables or disables Conferencing. The number of simultaneous 
conferences are:
On DK40i and DK424 systems, the CO line conference can be amplified with a customer-supplied 
two-way amplifier to improve the negligible loss encountered through the system over the public 
network (see “Amplified Conference” for details).
The basic application of this feature enables a station user to call voice mail during a conference 
call and play messages to all parties in the conference. The DTMF tones can be sent from any 
DK424 station in the conference.
Benefits
Provides a convenience to business, because everyone participating in the conference gets the 
same information at the same time reducing confusion and saving time.

Credit Card Calling (“0+” Dialing)
Callers can make “0+” telephone credit card calls from selected toll restricted stations. Calls are 
billed to the credit card instead of the Strata DK CO line. The “0+” credit card calling feature can 
be selectively assigned to stations and CO lines.
If a toll restricted station has the credit card calling feature, the Strata DK system requires the user 
to enter a certain number (programmable) of digits after dialing “0” on a CO line that has the 
feature. If the caller does not enter that number of digits within 20 seconds after dialing “0”, the 
call is dropped.
If the system has LCR, a station that has the feature can place a “0+” credit card call on any CO 
line accessed by LCR.
Benefits
Provides the convenience of “0+” telephone credit card calling without compromising toll 
restriction.
