Introduction
The ISDN Leased Line Support for C880 Platforms feature allows the user to configure a dial-up interface to obtain a leased line, which is virtually a permanent connection. After an ISDN BRI interface is configured for access over leased lines, it is no longer a dialer interface, and signaling over the D channel no longer applies.
This feature configures the BRI interface to use the ISDN physical connection as a leased-line service.
For an ISDN line, you can use the following:
•
Dial-on-Demand Routing (DDR) using snapshot routing—activated only when needed
•
