LOCATION FUNCTION
Front Used to identify the opposite end of a
cross-connect. The tracer lamp flashes
for approximately 30 seconds whenever
the tracer lamp switch is pulled out, and
remains lit while the tracer lamp switch
is left pulled out. If the module is cross-
connected to another module, the tracer
lamp on that module will also flash
approximately 30 seconds and then
remain lit.
Front Provides bridged access to the output
signal of connected office equipment to
allow monitoring without interruption.

Front Provides test or patch access to digital
equipment output terminations. Any
cross-connect to the X-O jack is disabled
and terminated to 75 ohm ground when-
ever a plug is in the OUT jack.
Front Provides test or patch access to digital
equipment input terminations. Any cross-
connect to the X-I jack is disabled and
terminated to 75 ohm ground whenever
a plug is in the IN jack.
Rear Provides direct access to the digital
equipment output (XO) or input (XI)
termination for cross-connecting to any
digital equipment output or input
termination via the cross-connect system.
Bottom Provides for connection from the digital
Rear equipment output (O) or input (I) termi-
nation.
Top Rear Provides for interconnecting of the tracer
lamps for the corresponding cross-con-
nects to allow tracer lamp operation as
described above. The connections
between the circuit modules should cor-
respond exactly to the XO or XI cross
connect jumpers. Cross-connect jumpers
are available with messenger cords which
accommodate both the cross-connect and
the corresponding lamp connection.
