We are facing a peculiar problem in PRI .At one point of time, we are able to use only firts 7 channels of PRI i.e. in case of failure of channlised E1 , only 7 remote sites are able to dial to PRI.
In short, only seven channels of PRI can be used either for outgoing or incoming.
This was the working PRI on 3745 router . Suddenly , this problem has cropped up .
can somebody help on same?
