Configuring Synchronous Serial Interfaces for WAN Support
Configuring Synchronous Serial Interfaces for WAN Support
Configure the synchronous serial interfaces on the motherboard to connect to a WAN through a
CSU/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.

Continuing Configuration Using the Command-Line Interface
Purpose
Enters enable mode (also called privileged EXEC
mode) and enter the password. You are in enable
mode when the prompt changes to
.
AS5400#
Enters global configuration mode. You are in
global configuration mode when the prompt
changes to
AS5350(config)#
AS5400(config)#.
Specifies the first interface to be configured.
If IP routing is enabled, assigns an IP address and
subnet mask to the interface.
Configures the external clock signal only if you
are configuring a DCE interface. The available
options include 1200, 2400, 4800, 9600, 14400,
19200, 28800, 38400, 56000, 64000, 128000, and
2015232.
Changes the shutdown state to up and enables the
interface.
Returns to enable mode.
