Configuring PPP with a Dialed Backup Line
You can configure PPP on the following types of physical interfaces:
•
Asynchronous serial
•
Synchronous serial
•
T1/E1
By enabling PPP encapsulation on physical interfaces, PPP can also be used on calls placed by the
dialer interfaces that use the physical interfaces. Refer to
for an example of an XSR
configured with one backup dial line to two different sites.

PPP:
1.
Enter interface serial <card/port> to specify the interface.
XSR(config)#interface serial 1/0
2.
Enter the media-type for the interface (default: RS232).
