Configuring T1/E1 Interfaces

To configure an ISDN PRI, channel-associated signaling (CAS) interface, or a T1/E1 multiflex trunk
interface, use the configuration software provided with your Cisco IAD or network module (if any).
Otherwise, for greatest power and flexibility, use configuration mode (manual configuration). In this
mode, you enter Cisco IOS commands at the prompt.
This section covers the following topics:
•
•
•
•
Before you begin, disconnect all WAN cables from the Cisco IAD to prevent it from running the
Note
AutoInstall process. Whenever you power on the Cisco IAD, if there is a WAN connection on both ends
and the Cisco IAD does not have a valid configuration file stored in NVRAM (for instance, when you
add a new interface), the Cisco IAD tries to run AutoInstall. It can take several minutes for the Cisco
IAD to determine that AutoInstall is not connected to a remote TCP/IP host.
This section describes basic configuration, including enabling the interface and specifying IP routing.
Depending on your own requirements and the protocols that you plan to route, you might need to enter
additional configuration commands.
Before you begin configuring the interfaces, make sure to do the following:

Purpose
Selects the controller as a candidate for the clock
selection algorithm according to the priority entered. Use
either slots 1/0 or 0/0.
In case of a serial interface, selects the serial controller
as a candidate for the clock selection algorithm
according to the priority entered. This applies only when
the serial interface is used for time-division multiplexing
(TDM) connections.
Exits to global configuration mode.
Returns to enable mode when you finish configuring
interfaces.
