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 fusing or pro- 
tection to comply with the requirements of 
UL 1459 Second Edition and CSA C22.2 
No. 225 standards. CO lines are connected 
to the system via W-1 1 modular connec- 
tors mounted on the bottom edge of the 
board. 
The 2x4 SLT Expander module also pro- 
vides the interface for four standard on- 
premise single line telephones (2500 type). 
Four 3W dc single line circuits am pro- 
vided on the printed circuit board. These 
singleline telephones canbe equipped with 
a standard message waiting lamp (9OV 
T&R) that operate on the -tip” and ‘ring” 
leads. Additionally, each circuit provides a 
loop intenupt (7OOms duration) to the con- 
nected SLT or device. ‘Ihe card will support 
single line telephones up to 2000 feet from 
the Basic KSU. On-premise single line tele- 
phones should present a load to the port 
totaling a maximum ringer equivalence of 
2.5. 
A mdex connector. 54 is located in the 
upper left comer of the 2x4 SLT Expander 
Module to provide ring generator capabfli- 
ties. It is recommended that the TelIabs 
8101. 30 Hz. SOVAC Ring Generator be 
used with this board. 
co Lines conneetione: 
CO Lines are conuscted to the system via 
modular R&l1 connectors mounted on 
the 2x4 SLT Expander Module and ac- 
cessed on the bottom of the Basic KSU. The 
2x4 SLT Expander Module connects CO 
Line ports 5 and 6 (when fnstalled on the 
Basic KSU) or ports 13 and 14 (when in- 
stalled in the Expansion KSU) to the sys-

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. An ON/OFF 
switch is located on the front of the power 
supply along with a slo-blow 5 amp fuse on 
the AC side of the transformer. The power 
supply provides an input for a 48V dc 
source for future use. Power is regulated 
and distributed to stations/circuitry inthe 
system on each printed circuit board. 
Three fuses located inside the power sup- 
ply protect the system fi-om over-current 
situations. The power supply and cabinet 
meet all safe@ requirements to cornply 
with UL 1459 Second Edition and CSA 
C22.2 No. 225 standards. 
The power supply is installed inside the 
system cabinet, on the right side, in the 
first card slot (J9). The power supply is 
designed to be an integral, structural part 
of the system. Do not attempt to install the 
system. or interface car&unless the power 
supply is installed with 3l.l four 
spews 
securely in place. The cabinet. includes the 
power supply already installed. The power 
supply is recognized underthe Component 
Program of Underwriters Laboratories Inc. 
The power supply is unique in 
that the 
transformer is not present on the power 
supply card and its enclosure. The trans- 
former is mounted inside the cabinet next 
to the bottom right of the backplane. When 
the power supply card is installed. the 
transformer is totally enclosed by the 
power supply card’s “L” shaped enclosure, 
and the right side of the cabinet. l’his cre- 
ates a totally enclosed. operational, power 
supply. Since the transformer is installed in the cabinet. and the power suppIy card 
is removable from the cabinet, the AC coh- 
nections are made directly to the system 
backplane. 
[WARNING! 
Since hazardous voltages are always 
present on the backplane while the 
system AC power cord is plugged in. 
AT NO TIME SHOULD ‘I3IE POWER 
SUPPLY CARD BE REMOVED WHILE 
THE SYSTEM AC POWER CORD IS 
PLUGGED IN. THE POWER SUPPLY

PLUGGED IN. There are very few in- 
stances when the power supply card 
should be removed. If an instance 
arises where it must be removed, AL 
WAYS unplug the system AC power 
cord FIRST. 
The power supply cord plugs into an iso- 
lated, dedicated, (with dedicated ground) 
1 I7V ac outlet for power. This is necessary 
to prevent possiblevoltage spikes and tran- 
sients that may be caused by equipment 
sharing the same AC circuit. 
The AC connection to the power supply 
requires a parallel blade with a ground 
receptacle. A three wire to two wire isola- 
tion adapter should not be used. The use 
of a surge suppressor is required. 
G1ollmuxlg: 
A No. 12 AWG copper wire should be used 
to connect a ground between the ground 
source and the KSU (25 feet m-urn). A 
two position terminal strip (J10) is located 
on the lower left comer of the motherboard 
and is accessible through the left side of 
the KSU. One tennina position can be 
used to connect the ground wire &om a 
ground source. 
B. Cabinet Iu&aUation 
Once the area for the telephone equipment 
has been selected. mount a plywood back 
board to the wall. ‘Ihe back board size will 
vary depending upon the size of the MDF. 
The entire system and frame can be 
mounted on a 4’ x 6’ x 3/4” plywood. If 
mounting the cabinet alone, the minimum 
back board size is 25” x 17” x 3/4”.

This plug-in card is the only common 
equipment card required to make the sys- 
tem operational and controls all system 
activity. The CPB contains the rnatn micro- 
processor a 16-bit (68000) and a real time 
clock which controls all system functions 
including the PCM/TDM voice switching 
under direction of ROM and F&M software 
coding. The CP3 is responsible for aJl con- 
trol functions. execution of ail logic opera- 
tions and control of system modules 
including control over circuitry necessary 
forvoice swftching and confkence connec- 
tions. The CPB is also responsible for all 
system tones, system timing, and station 
status control. ln addition the CPB also 
provides software andhardware support to 
ensure the following: 
L 
l Watch dog timer and recovery. 
l PCB status as to presence/absence of 
cards for automatic software confiiura- 
tion setup. 
. Interpret an ID code from each PCB so 
that card type can be determined auto- 
matically. 
l State/event so- design. 
l Battery backup of customer database 
RAM memory. 
The CPB contains the circuitry and 
con- 
nection (RCA type) for background mu- 
sic/music on hold, and the standard 300 
Baud Modem. An optional 1200 Baud Mo- dem can be iastalled on the CPB to allow 
the on-board modem to transmit at ti 1200 
baud rate. In addition there is one RS- 
232C modular connector input/output 
port on the CPB and a connector to support 
the use of an 
optional I/O expansion mod- 
ule. The I/O expansion module adds RS- 
23X!. I/O port and one RS-422 l/O portto 
the system for a system total of three I/O 
ports. A reset (halt) push button switch 
and a BGMjMOH volume control potenti- 
ometer is located on the front of the printed 
circuit board. Refer to Figure 500-9 Basic 
KSU Equipment Cabinet for CPB layout 
and location of connectors. 
System software is provided in EPROM 
memory and is installed on the CPB. The

is equipped with 256K of battery-backed 
static RAM. Rovisions have been made on 
the card to address up to four megabytes 
of EPROM memory and up to two mega- 
bytes of static RAM. 
An option -dip” switch located on the CPB 
allows the system EPROM memory to be 
configured 
utiliziq difh-ernt size EPROM 
chips. 1 Megabit, 2 Megabit, 4 Megabit and 
8 Megabit chips may be used to provide the 
generic software. Refer to Section 800, 
Maintenance and Troubleshooting for 
‘dip” switch settings for various allowable 
confiiffoRs. 
The CPB allows tie use of either 
1 Megabit 
or 4 megabit static RAM chips to be used 
for F?AM memory. The size and type of 
memory used is automatically determined 
and set by the system. 
The battery backup strap must be 
placed in the “ON” position to activate 
memory battery backup (J3}. Do this 
prior to inserting the CPB into the 
KSU. Refer to Figure 500-9 Basic KSU 
Equipment Cabinet. If the optional 
1200 baud modem module or expan- 
slon I/O module are to he installed. do
