Lan Interface; Dsx1 Connections - ADC PG-PLUS PCS-718 Technical Practice

Backplane Connections

LAN Interface

The COT shelf supports communications between multiple shelves by means of a 10Base2 BNC LAN connector.
This feature requires a PMU installed in the COT shelf. Refer to the PMU documentation for additional
information on this interface.

DSX1 Connections

The COT shelf provides terminations for eight DS1 inputs from the DSX-1 cross-connect by way of wire-wrap
pins located at the bottom right hand side of the shelf backplane. The DS1 inputs are bridged to both PMX slots
to allow for 1:1 equipment protection. The 100 Ω termination resistors are included on each of the DSX1 IN
connections.
