Serial module for use when running Raw, Hybrid, IP over serial (HDLC) and Serial Over IP DTE mode that provides single DIN connector (RS-530/V.35). Used with the VX900 only; this port is not applicable to the VX900C.
See the Serial Interface Card Cables Specifications topic for additional cable and connector specifications.
The following DTE cables are required for the one-port serial interface card.

Two cable types can be used with the one-port Serial WAN interface card:
The EIA 530 Cable assembly is constructed with one end of the cable terminated in a high-density 26-way HD-Type plug and the other end terminated in a 25-way D-Stub plug. This cable enables the connection of the serial WAN interface card with an EIA 530 DCE device. The connections are shown below.

Crypto Resync
VX supports crypto resynchronization on EIA-530 interfaces. When configured for crypto resynchronization, VX send HDLC keep alive messages when the line is operationally DOWN. Use the following guidelines to set up the hardware connection for crypto resynchronization on a VX system:
