lines are terminated on RJ14 jacks mounted near
the MDF: Every two C.O. lines are connected directly to
the corresponding C.O. jacks on the KSU, using 2-pair

If the C.O. lines are terminated on RJ14 jacks mounted away
from the MDF: Using a 2-pair line cord, every two C.O.
lines are first terminated from the RJ14 jacks onto modular
jack assemblies that are mounted next to the RJ14 jacks.
Using 2-pair cable, the lines are extended to modular jack
assemblies that are mounted on the MDF backboard. A 2-pair

3.01 The KSU is a compact, wall-mounted unit that houses the
system power supply, the Main Control PCB, and the optional Expansion PCB.
The KSU performs all control and switching activities for the system, including detecting incoming C.O. calls,
storing speed-dial numbers,
processing data-controlled features,
and controlling the interaction between keysets, C.O. lines, and
intercom channels. Refer to the next page for a photograph of
the KSU.
3.02 The system is a microprocessor-controlled, space-division
switching system. The 14 audio channels include:

MAIN CONTROL PRINTED CIRCUIT BOARD (PCB)
SPECIFICATIONS
Issue 1,
November 1985
3.08 The Main Control PCB contains the main controlling micro-
processor and its associated control logic and memory circuitry,
a battery for data base protection, system timers, circuitry for
music-on-hold and external paging,
and circuitry for three C.O.
lines and eight keysets. Refer to Figure 2-2 on the next page
for a photograph of the PCB.
3.09 The Main Control PCB functions under the control of a pro-
gram that is activated when the KSU is powered up.
The PCB is in
constant communication with the microprocessor in each keyset.
3.10 There are 8K bytes of random-access memory (RAM) and a min-
imum of 16K bytes of read-only memory (ROM) for use by the Main
Control PCB. The software code for the main generic program is
stored in the non-volatile ROM memory,
and the programmed data
base and speed-dial numbers are stored in the RAM memory.
3.11 The RAM memory is protected by a lithium battery. The bat-
tery will protect the programmed data base until the accumulated
system downtime exceeds one year. Under normal system use, the
battery should last approximately 10 years. The PCB is shipped
with a piece of paper between the battery and the battery clip to
nrevent any discharge i~n_til the I(.St.l is installed,
IT--- ----
3.12 The system timers provide timeout limits for nine system
features. All timers are preset during initialization and seven
of the timers are programmable. The timers are described in the
PROGRAMMING section.
3.13 If a customer-provided music source is installed, the
music-on-hold circuitry provides two channels of music for two
C.O. lines on hold. Refer to page 7-4 for more information. In
addition,
as background music,
the music source can be heard through keyset speakers
and camped-on intercom callers hear the
music while waiting. The music-on-hold circuitry automatically
holds the volume to a predetermined level that is slightly lower
than normal voice volume,
as required by FCC regulations.
The
optimum input level is l.OVRMS.
3.14 There are three lA, 25OV, fast-acting fuses on the PCB to
