ISDN PRI (E1) 30 channel configuration

To configure a ISDN PRI (E1) 30 channel for leased line backup , should I create serial0/0:15 or serial0/0:23 or serial0/0:30 ?

Do I have to create the Dialer profile for the serial interface which I create for the ISDN PRI ?

Re: ISDN PRI (E1) 30 channel configuration

An E1 PRI that will back up a serial

line (or even be used for regular dial

traffic) would be serial0/0:15. I'm not

sure about your last question; the

interface serial0/0:15 is an ISDN D-

channel that will be used to manage

the control traffic for the B-channels;

there is no leased-line serial interface

with the PRI. If you are wanting to use

your ISDN line as a leased line, then you

would need to use a BRI and not a PRI.
