1. Connector cables for WAN line cards may be ordered from Enterasys Networks.

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:

Table 52. SSR-SERCE-04-AA and SSR-SERC-04-AA Cable Types

Enterasys Part Number	CSU/DSU Connector Type		Standard
SYS-SV35-DTE	Two (2)	V.35 34-pin connectors1	V.35
SYS-S530-DTE	Two (2)	DB-25 25-pin connectors	EIA-530
SYS-S449-DTE	Two (2) DB-37 37-pin connectors		RS-449
SYS-SX21-DTE	Two (2) DB-15 15-pin connectors		X.21

1.The two remote ends of each type of connector cable are labeled “Port A” and “Port B”. “Port A” corresponds to Port 1 or 3 on a Quad Serial – C/CE WAN card, depending upon which line card port you are using. Similarly, “Port B” corresponds to Port 2 or 4 on a Quad Serial – C/CE line card.

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.
