Cable-To-Bay Termination
Office/equipment cables should be terminated to BNC connectors at the back of the DSX-4U
circuit modules. A rear view of a DSX-4U chassis with all circuit modules in place is shown in
Figure
2-6.
Terminate each pair of cables from any one office equipment unit to the IN and OUT connectors
on any one circuit module. Terminate the cable carrying signals to the bay (left side of bay as
viewed from front) to the OUT connector and the cable carrying signals away from the bay to
the IN connector. Secure all cables to the cable bar on the rear of the chassis by use of tie-wraps.
Record all equipment terminations on the labels provided on the front of each module. Record
cross-connect terminations on the adhesive-backed designation labels provided on the back of
the chassis.
