System:DK14 
Circuits per PCB:two serial interface ports 
Interfaces with:SMDR connection for call accounting device

Older Version(s):none
The WSIU1 PCB enables the DK14 system to connect to various hardware devices. It does not 
have an internal modem and does not support IMDU or RMDS.
Only one WSIU1 can be installed per DK14 system. When installed, the WSIU1 port functions are 
identified and enabled automatically when power is turned on. See Program 76-1 for initialized 
data. 
CO lines that receive Caller ID must be cross-connected to the TC-1041 (MLX-41) Caller ID 
interface box. See Figure 1-18 for wiring.
The TC-1041 (MLX-41) is available from TEL-CONTROL, Inc., P.O. Box 4087, Huntsville, AL 
35815-4087. Phone (205) 881-4000. 
The communication parameters for TTY and Caller ID (WSIU1 SI01 or SI02) ports are:
©Data word bits = 7
©Parity = even
©Stop bits = 1
The communication parameters for SMDR (WSIU SI01 or SI02) are:
©Data word bits = 8
©Parity = None
©Stop bit = 1

WSIU1 Installation
1. Make sure that the power supply switch is OFF. See 
Figure 1-14.
2. Slide the front edge under the System Frame Ground Bar. 
Align and insert WSIU connector J4 into the 
motherboard connector J21, and J3 into J20. Apply firm, 
even pressure to ensure proper making of the connectors. 
Make sure the edge of the WSIU is next to the connector 
J1 and J2.
3.Remove the “knock-out” from the KSU cover SI01 or 
SI02 access slot, and store the “knock-out” in the slots 
provided in the KSU base. (See Figure 1-11.)
WSIU Programming
Program 03: 
No assignment is necessary. WSIU1 is 
automatically enabled when installed and power is turned 
ON. It is not assigned to a slot.
Program 76-1X-Y: 
Assigns each installed WSIU1 port to a 
function. Where X identifies the WSIU1 port number (1~2) 
and Y identifies the WSIU1 port function:
©Y=1, RS-232 TTY (Program 77-1, LED 14 OFF)
©Y=2, SMDR
©Y=4, SMDI
©Y=6, Caller ID Interface
©Y=0, No function - this should be used for any WSIU1 ports that are not used.
Program 76-2X-Z: Assigns each installed WSIU1 port to operate at a specified transmission rate. 
Where X identifies the WSIU1 Port number (1, 2). Z identifies the WSIU1/port transmission rate 
in bits-per-second (bps):
©Z=1; 9600
©Z=2; 4800
©Z=3; 2400
©Z=4; 1200
NoteThe sum of WSIU1 port 1 and port 2 bps rate cannot exceed 9600 bps.
WSIU Wiring
NoteRefer to Chapter 10 – Peripheral Installation, SMDR and TTY for WSIU wiring/
interconnecting details. See Figure 1-18 for Caller ID interface box to WSIU wiring.

DK8/DK14 Compatibility
Strata DK I&M 5/991-21
DK14 InstallationDK8/DK14 Compatibility
Generally, Strata DK components are upward compatible to make upgrading cost-effective. 
Furthermore, there is a lot of cross-compatibility between similar systems. Most of the PCBs that 
were introduced for the DK14 can also be used in the DK8 system (see Table 1-2). Also, a number 
of DK8 PCBs can be used in the DK14 (see Table 1-3).

Important!To protect against transient voltages and currents, solid state secondary protectors 
must be installed if there is outside wiring. These protectors, which contain fast 
semiconductors in addition to fuses, shall comply with the requirements for 
secondary protectors for communication circuits, UL497A. 
Care must be taken to ensure that they are very well grounded to a reliable earth 
ground. Recommended protectors are available in the fast Series 6 line from 
ONEAC® Corp., Libertyville, Illinois 60048, (800) 327-8801. Install and test the 
secondary protectors precisely to the installation instructions of thee manufacturer.

PT/PR can also be used with normal 
station runs.
3. DKT circuits (1~4) are standard on 
the DK14 main PCB.
4. DKT circuits (5~6) require one 
optional QCDU2 circuit and DKT 
circuits (7~8) require a second 
QCDU2 to be installed.

Strata DK I&M    5/992-1
DK40i Configuration2
This chapter explains how to configure a Strata DK40i system. It also provides tables for recording 
the hardware and station devices that make up the system.
Base Key Service Unit (KSU)
Station and CO Lines
The DK40i Base KSU comes equipped with eight digital telephone station circuits. One of three 
optional PCBs can be added to provide either four loop start or DID lines, or two ISDN BRI S/T 
circuits (Ta b l e  2 - 1). An optional TCIU2 Printed Circuit Board (PCB) can be added to the Base 
KSU loop start line PCB to provide Caller ID interface. An optional KSTU2 PCB can be added to 
provide four standard telephone circuits (ports).
NoteAn Expansion KSU can be added to the DK40i to increase the system capacity to 28 
station ports and 12 lines.
Peripherals
The DK40i Base KSU can support a number of peripherals, which are not considered as stations or 
lines and do not affect the maximum station and line capacities. The DK40i Base KSU comes 
standard with built-in interfaces for connecting the following dealer-supplied equipment: an 
amplifier and speaker for paging and night ringing, Music-on-Hold (MOH) source, reserve power 
batteries, and emergency standard telephone for system power failure occurrences when using 
loop start lines in the base cabinet.
A relay contact is also provided to control one of the following peripherals: MOH source, night 
bell, or page amplifier mute control.
An optional KSTU2 PCB provides an alternate background music source interface. The music 
plays through Toshiba telephone speakers, as opposed to the external page speakers. 
The optional TSIU PCB provides two RS-232 interface ports to connect two of three options: a 
DKAdmin PC (or external modem for remote maintenance); or VM SMDI; or an SMDR port to 
connect a call accounting device or printer. An Expansion Unit RS-232 interface PCB is required 
if all three features are needed.
