Cabling X.21/V.35 Connectors

Four cables are available for the X.21/V.35 I/O modules:

•X.21 DCE cable (terminated with 8 female X.21 connectors)

•X.21 DTE cable (terminated with 8 male X.21 connectors)

•V.35 DCE cable (terminated with 8 female V.35 connectors)

•V.35 DTE cable (terminated with 8 male V.35 connectors)

Each 200-pin proprietary socket on the I/O module provides connections to 8 V.35 or X.21 ports. The remote end of the cable is terminated with either 8 X.21 connectors or 8 V.35 connectors. The cable you attach to the port on the I/O module determines whether the connection is X.21 or V.35 and DCE or DTE.

To cable I/O modules with X.21/V.35 connectors:

1Insert the X.21/V.35 connector into the selected socket.

2Terminate the other end in the appropriate network connection.

3Repeat steps 1 and 2 for the other socket.
