On our trusty old 4700 with an 8x BRI module and a cE1/PRI module running IOS 12.2, I'm trying to set up ISDN dial backup for an E1 leased line. The E1 is terminated on the cE1/PRI. Five of the eight BRIs are connected to a PABX and normally serve for dial-in, but up to four of them could be diverted to dial-out in an emergency. The docs on CCO leave me with some open questions.
My draft config so far (incremental to the currently working config):
--------8
