Configuring Synchronous Serial Interfaces For Wan Support - Cisco AS5350XM Configuration Manual

Continuing Configuration Using the
Command-Line Interface
The information in this chapter applies to the Cisco AS5350XM and Cisco AS5400XM universal
gateways. This chapter continues where the
chapter ends. After you have commissioned your Cisco AS5350XM or Cisco AS5400XM universal
gateway, you might want to configure other features that include serial interface support, T1 channel
groups, and signaling.

the end of this chapter a useful reference for configuration.

Configuring Synchronous Serial Interfaces for WAN Support

Configure the synchronous serial interfaces on the motherboard to connect to a WAN through a CSU or
DSU.
This section describes how to enable the serial interface, specify IP routing, and set up external clock
timing on a DCE or DTE interface. To use a port as a DTE interface, you need only connect a DTE
adapter cable to the port. When the system detects the DTE mode cable, it automatically uses the external
timing signal. To use a port in DCE mode, you must connect a DCE interface cable and set the clock
speed with the clock rate configuration command. You must also set the clock rate to perform a loopback
test.
