Configuring Dial Backup and Remote Management Through the ISDN S/T Port
Configure the Aggregator and ISDN Peer Router
The aggregator is typically a concentrator router where your Cisco router ATM PVC terminates. In the
configuration example shown below, the aggregator is configured as a PPPoE server to correspond with
the Cisco
876 router configuration example that is given in this chapter.
The ISDN peer router is any router that has an ISDN interface and can communicate through a public
ISDN network to reach your Cisco router ISDN interface. The ISDN peer router provides Internet access
for your Cisco router during the ATM network downtime.
