Parameter
number: Number of the ISDN B channel for leased line connection. It is in the range 0 to
1 if the channel is on a BRI interface, and in the range 0 to 30 on a PRI interface, and 0
to 23 on a CT1/PRI interface.
Description
Use the dialer isdn-leased command to configure an ISDN B channel (can be either
the channel on a BRI or PRI interface) to be the leased line.
