To Cable a System as a Multiplexer
Step Action
1. Connect the DS1 signals to the wire-wrap
pins on the front of the chassis:
a. Connect 24 AWG cross-connect wire to
the pins.
b. Route the wire down through the fanning
strip and out.
c. Record designations on the label inside the wire-wrap door.
ALERT
ALERT! DO NOT connect the tracer lamp (TL) signal between
systems that operate on different supply voltages, such as be-
tween a +24Vdc system and a -48Vdc system. Industry
standard tracer lamp circuits are designed to operate with a
single system-wide voltage.
NOTE
If you prefer to connect the DS1 signals to the rear 64-pin connectors, see
“To Cable a System as a DSX” on page 2-9. This method of connecting the
low speed signals does not provide signal patching capabilities.
2. If your application requires changing the default Logic ground,
Coax Shield TX ground, and Coax Shield RX ground settings,
move the three DIP switch toggles to the desired position before in-
stalling the DS3 BNC connectors. See the table on the next page for
definitions of each toggle.
