6.00 The following precautions should be adhered 
to when installing telephone wiring: GROUND 1; THIRD WIRE GRO;ND 
 TO AC POWER CORD 
WARNING! 
1. Never install the telephone wiring dur- 
ing a lightning storm. 
2. Never install the telephone jacks in wet 
locations unless the jack is specifically 
designed for wet locations. 
3. Never touch uninsulated telephone 
wires or terminals unless the telephone 
line has been disconnected at the net- 
work interface.

1 INTRODUCTION 
1.01 STRATA DK systems are flexible in their 
ability to meet varied system needs. A modular 
building block approach allows the addition of vari- 
ous parts to meet system needs and applications. 
A universal slot concept is used in the KSU, which 
means that a PCB slot in the KSU can accept any 
one of a number of different PCBs. This is con- 
trasted with a dedicated slot approach (used in 
previous STRATA systems),...

Each of these PCBs requires one universal 
slot, so a total of five slots is required. There- 
fore, a DK24 can be used. 
Example 2-A bank branch office needs nine CO 
I lines, seven electronic telephones, five digital 
telephones, and 11 standard rotary type tele- 
phones.

3 common equipment) is as follows: 
Three PCOU PCBs

telephones). Each DDSS console does not require 
a specialized interface PCB; instead, each DDSS 
console takes the place of one digital telephone on 
a PDKU PCB. However, only one DDSS console 
may be interfaced to a PDKU, and it must interface 
to circuit 8. Likewise, each DSS console does not 
require a specialized interface PCB; instead, each 
DSS console takes the place of two electronic 
telephones on a PEKU PCB. However, only one

be needed. The three CO linescan be handled 
by one PCOU PCB. 
The two modems are configured in a system 
modem pool and if no dedicated CO lines are 
provided, then one standard telephone 
(PSTWPESU) station port is required for 
each; therefore a PESU or PSTU would be 
needed. The PCBs required for this configu- 
ration are as follows: 
Two PDKUs 
One PCOU 
One PESU or PSTU 
A total of four universal stations needed.
