Signaling Standards

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