Modifying the BRI T4 Timer
Using Site Manager, you can edit a timer for the BRI leased line. Although call
setup is not performed on the D channel, the ISDN switch uses the D channel to
send and receive bits that activate and deactivate the ISDN interface. You may
want to edit the D channel for your leased-line configuration.
If noise or other minor problems on the network cause the router to deactivate the
line frequently, you can modify the BRI T4 timer to prevent this from happening.
To modify the BRI T4 timer:
