70 ! Cabling I/O Modules
SC duplex connectors have the same basic shape as LC duplex connectors, but are
slightly larger. See Figure 38.
SMB Connectors
To cable I/O modules with SMB connectors, pull back the metal sheath on the
connector, insert the connector into the selected port, and release the metal sheath.

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.
