DSX-1 Termination, Office Timing, Office Alarms,
and the Shelf Alarm are connected via JP15. Figure 5
gives a detailed look at each of the connections of
JP15.
DSX-1 and DS1
DSX-1 and DS1 connections are made via JP15, pins
1 through 5 (see Figure 6). The Line Interface Unit
(LIU) List 1, part number 1150079L1, provides
termination for a DSX-1 signal only. The LIU List 2,
part number 1150097L2, provides termination for
either DSX-1 or DS1 signal. Line build-out and
equalization settings are made on the Bank Controller
Unit (BCU).

The Office Timing input/output pins are located on
JP15, pins 11 through 16 (see Figure 7). The
incoming Building Integrated Timing Supply (BITS)
connects to pins LX (in) and LY (in); EU2 is used to
