Basic WAN Configurations
Basic ISDN Connections
If this router are configured as an ISDN bridge/router, it may establish WAN connections
to other bridge/routers via ISDN (Integrated Services Digital Network) connections.
Before the router can establish an ISDN connection to another ISDN router, the ISDN
information must be defined. The ISDN switch type must be defined for the ISDN
interface, and the phone numbers must be defined. Refer to the following diagram that
shows three router units connected together with two ISDN B-channels being configured
on each unit.
