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.
