WAN Ports

The following figure shows the 12 WAN ports on the WAN BICs on the back panel of

the SWAN 2 concentrator. Each WAN port has a 50-pin connector, which can support

the RS-232, RS-449, X.21, and V.35 electrical interfaces, even though this connector

does not physically match any of the connectors used for these interfaces.

HP provides four types of interface converter cables to convert the 50-pin connector

to a connector that matches your interface (see Supported Electrical and Physical

Interfaces on page 1-2). Each interface converter cable type supports, both electrically

and physically, one of the supported electrical interfaces. Four sense pins in the

50-pin connector are wired to indicate which type of interface converter cable is

attached, enabling the SWAN 2 concentrator to know which electrical interface is

connected.

The interface converter cables of the SWAN 2 concentrator (T3881) are identical to the

interface converter cables of the earlier SWAN concentrator (T3880). For migration

purposes, you can disconnect the interface converter cables from a

SWAN concentrator (T3880) and connect them to a SWAN 2 concentrator (T3881).
