[Asterisk-Users] <--PRI--> * <--PRI--> modem bank - problems

[Brian D Heaton]

Gary,

	What does your clocking setup look like?  In a general telco sense I
would expect it should look something like this:

LEC PRI I/Fto *: Loop
* PRI I/F to Modem Bank: Internal
Modem bank PRI I/F to *: Loop

Got a smart CSU (or two) you can put inline on the PRI lines and take a
look at the ESF channel messages?
