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.
