DSX O

PERATION

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.
