DSX-1/E1 Interfaces
The DSX-1/E1 interfaces are 64-pin amphenol connectors. These interfaces provide Tx and Rx connec-
tions between the unit and equipment such as wire-wrap patch panels, punch-down panels, or breakout
panels.
NOTE
Connect the DSX-1/E1 interfaces to intra-building wiring only.
Power Connection
The DC and AC power connections are described in Power Up on page 2-2.
External BITS Clock
The external BITS clock connections are made through wire-wrap pins. It is possible to connect two exter-
nal BITS clocks in this manner. This allows either one or two external BITS clocks to be used for unit
timing. Each BITS clock terminates on three wire-wrap posts. The posts are tip, ring, and shield and are
labeled
T, R, and S for clock A and clock B.
