CO Line/St&on Interfaces: 
The 2x4 SLT Expander Module provides 
the interface for two Central Office, Cen- 
trex or PBXloop start, lines. The protection 
circuitry necessary to allow the system to 
be classified as a fully protected system are 
located on the card for each CO circuit. The 
CO circuits are equipped with current 
sensing circuitry that identifies distant end 
disconnect (loop supervision). The module 
design also provides proper...

E. 4x8 Expandu Module 
The 4x8 
Expander Module is a four CO by 
eight digital key station Interface module 
that may plug onto the main key service 
board of the Expansion KSU only. This 
module is a combination board that con- 
tains the necessary Circuitry to connect 
four CO/Centrfx/F’EIX loop start lines and 
eight digital key telephones to the system. 
This card also contains one additional 
voice (transmit) path for external paging, 
and a...

Module Grounding: 
A No. 12 AWG stranded wire is used to 
connect a ground between the 4x8 Expan- 
sion Module. and the main key service 
board of the Expansion KSU. A two posi- 
tion terminal strip (p3) is located along the 
bottom edge of the main key service board 
and is accessible through the bottom of the 
Basic KSU. One terminal position on the 
P3 connector is used to connect the ground 
wire from tbe Basic KSU to the Expansion 
KSU. 
The other 
terminal position is used to con-...

Refer to Figure 500-9 Basic KSU 
Equipment Cabinet for circuit board layout 
and location of connectors. 
Power supply: 
The power supply is installed in the KSU 
cabinet at the time of manufacture and 
ships with the KSU. The power supply in- 
put voltage is 117V ac. i-10?!. The power 
supply provides power distribution 
of fiI- 
tered/unregu.lated 12Vdc and aregulated 
-EN dc to the backplane bus....
