Signaling Standards Supported
The synchronous serial ports available for the router support the following signaling
standards: EIA/TIA-232, EIA/TIA-449, V.35, X.21, and EIA-530. You can order a Cisco
DB-60 shielded serial transition cable that has the appropriate connector for the standard
you specify. The documentation for the device you want to connect should indicate the
standard used for that device. The router end of the shielded serial transition cable has a
DB-60 connector, which connects to the DB-60 port on a serial WAN interface card. The
other end of the serial transition cable is available with a connector appropriate for the
standard you specify.
The synchronous serial port can be configured as DTE or DCE depending on the attached
cable (except EIA-530, which is DTE only). To order a shielded cable, contact customer
service.
