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.
