Hi All!
The problem is following:
till today we got PRI so:
(Router)---PRI---(Nortel PBX) ----PRI------(Telco)
we don't use Nortel PBX and don't want to pay a rent for it. So now we've connected:
(Router)----PRI------Telco
But now I get ISDN Se0/2/0:15 Q931: Ux_DLRelInd: DL_REL_IND received from L2 and have no communication
And L2 status changes periodically from TEI_ASSIGNED to AWAITING_ESTABLISHMENT
running config:
network-clock-participate wic 2
isdn switch-type primary-net5
controller E1 0/2/0
framing NO-CRC4
clock source internal
pri-group timeslots 1-31
interface Serial0/2/0:15

Have somebody hint how to solve the issue?
