DSX OPERATION

When a MIX 56 system is used as a DSX only, with DS1 signals connected to the rear 64-pin connectors, or as a multiplexer with DS1 signals connect- ed to the front wire-wrap pins, you can perform all DSX functions includ- ing cross-connecting circuits with other network elements, rerouting traffic with patch cords, and nonintrusive monitoring signals.

NOTE

If the system is used as a multiplexer, but the DS1 signals are connected to the rear 64-pin connectors, you cannot reroute traffic with patch cords.

Patching Signals

! ALERT

ALERT! When using a MIX 56 system as a multiplexer, you must route DS1 signals to the front wire-wrap pins to be able to patch signals.

If you need to perform network maintenance or emergency patch-arounds, you can reroute incoming and outgoing lines by making temporary connec- tions using either two single patch cords or a dual patch cord. Patching is service-affecting, and the circuit is briefly interrupted while setting up and taking down the patch.
