Cabling and Connector Specifications
The following table lists the media specifications for the Quad Serial – C/CE line cards.
Connectivity Guidelines
The SSR-SERCE-04-AA and SSR-SERC-04-AA line cards each use the same 60-pin LFH-60 high
density connector to link to their respective Channel Service Units/Data Service Units
(CSU/DSUs).
Enterasys offers the following four cables, used to connect the SSR-SERCE-04-AA and
SSR-SERC-04-AA line cards to standard CSU/DSU modules:
Note: Because the LFH-60 high density connectors on Quad Serial – C/CE line cards contain
two serial WAN ports per interface, all four cable types defined above feed two CSU/DSU
ports.
