You need the following items to cable a system as a multiplexer with full
DSX functionality:

90-degree connectors, as shown below)
• One RJ-45 Ethernet cable (shielded, groundable)

• Straight-wired DB-9 RS-232 cable
The only items needed to cable a system as a DSX are two 64-pin male ca-
bles and two cable tie wraps.
To Cable a System as a DSX
Step Action
1. Connect two 64-pin male cables to the two female connectors on
the rear of the chassis marked DS1 In and DS1 Out.
2. Tighten the two screws on each connector to secure the connectors
to the chassis.
3. Secure the cables to the chassis using tie wraps, as shown here:
NOTE
Prevent ground loops—check the site’s grounding practice standards.
Do not attach drain wires when using the system as a DSX. Only attach
drain wires when cabling the system as a multiplexer and connecting the
DS1 signals to the rear 64-pin connectors.
