I just worked through this same scenario. The PRI will not dial out to the
BRI when the frame-relay goes down, the BRI will have a backup statement to
dial when the frame-relay fails. I have sample configs: but COO has them
too.
First you will need to have the switch type from Telco...
PRI side
[isdn switch-type primary-dms100] global config
Next you will configure the controller:
controller T1 3/1
pri-group timeslots 1-24
description PRI for collector site BRI
framing esf
linecode b8zs
verify framing and line code with telco....
You will need to decide if you will use authentication
username fff-lbs-rt password 0 tapew0rm
username fff-lbs-rt password 0 tapew0rm
add authentication statement to each side of the connection in global
config.

Subject: dial backup (pri-to-pri and pri-to-bri) [7:21030]
hi.
I need help about isdn dial backup.
I have one central office and about 10 branches.
I will get frame relay connections between central office and branches.
I want to do dial backup with isdn. in central office pri and branches bri.
is it possible to configure central office (i mean pri) will set up dial
backup connection.
i mean pri-to-bri dial backup
when frame relay goes down central site will set up one or two b channels to
each of branches.
if someone has sample config of this scenario or has any idea i will be very
happy.
thanks
best regards.
