ISDN PRI Voice E1

[rasankalakmal]

the SP provided a ISDN PRI voice E1 (q931)and told me they have enabled 4 channels for testing. when i plug the link to router, there is an alarm in the router and SP's rack alarms get cleared. attached herewith router config and error when trying to make a call.

when loop E1 port, it's perfeclty working.

Hi, something seems wrong with the circuits, please send output of "show controllers e1" and "show isdn status".

[rasankalakmal]

hi, requested informatin attached herewith.

[paolo bevilacqua]

Hi, your circuit is down, check cabling to network termination.

[rasankalakmal]

Extremely sorry! the correct information attached herewith. ealier i was testing and at that time cable was unpluged.

[paolo bevilacqua]

Same thing, circuit is down.

[rasankalakmal]

but SP's rack alarms got cleared and the E1 port indicators as follows.

CD-green

LP-nothing

AL-amber

[paolo bevilacqua]

AL - amber means you got an ALarm, because router got no signal.

[rasankalakmal]

AL got cleared after putting framing NO-CRC4 under controller. but the attached error occured when making calls.

[paolo bevilacqua]

Hi, you said you got four channels for test, but your pri-group is configured with 31. The connected switch is telling you that exactly.

Shutdown voice-port, remove pri-group, reconfigure it with timeslots 1-4 and you should be going.

[rasankalakmal]

unfortunatly, the prob is still there. attached herewith updated config & error

[paolo bevilacqua]

Now you have to ask your telco why the call is not accepted on channel 4. Sometime they say they have done everything, just to find isn't quite the case.
