E1 is UP, but not working

Hello Everyone,

I am having a bad time configuring a E1. Eveything seems to be fine and up, but i cannot get to make a phone call. My telco says everything is fine on their side, but I get this results on the E1 controller:

R_POTOSI#show controllers e1

E1 0/0/0 is up.

Applique type is Channelized E1 - balanced

No alarms detected.

alarm-trigger is not set

Version info FPGA Rev: 08121917, FPGA Type: PRK1

Framing is NO-CRC4, Line Code is HDB3, Clock Source is Line.

International Bit: 1, National Bits: 11111

Data in current interval (195 seconds elapsed):

0 Line Code Violations, 0 Path Code Violations

0 Slip Secs, 0 Fr Loss Secs, 0 Line Err Secs, 0 Degraded Mins

0 Errored Secs, 0 Bursty Err Secs, 0 Severely Err Secs, 0 Unavail Secs

Total Data (last 5 15 minute intervals):

23 Line Code Violations, 287 Path Code Violations,

3 Slip Secs, 0 Fr Loss Secs, 2 Line Err Secs, 0 Degraded Mins,

4 Errored Secs, 9 Bursty Err Secs, 0 Severely Err Secs, 1680 Unavail Secs

I read that the Line Code and Path Code Violations are due to physical line problems, but they say that everything is OK since the E1 is UP. Are they right? If not, how can I prove them wrong.

Thanks in advance for the help

Post your config of the controller.

Chris

Hi Chris, this what I'v got configured:

controller E1 0/0/0

framing NO-CRC4

pri-group timeslots 1-31 service mgcp

Is this a pri circuit?  Can you post "sh isdn status"?

Since you are using MGCP do you have MGCP configured on the GW and in CUCM?

Chris

Yes, this is a PRI circuit. MGCP is properly configured on CUCM. I have a couple of FXOs that are working just fine.

Router#show isdn status

Global ISDN Switchtype = primary-net5

        dsl 0, interface ISDN Switchtype = primary-net5

Cool, can you get "debug isdn q931" for the failed call?

Chris

I've got the debug Chris:

Thanks for the help

Bruno,

The status and config look correct

debug isdn q931 and make a test call

post the output of the debug

Alex.

Regards, Alex. Please rate useful posts.

Hello Alex, I've just posted the debug output on the question above.

The calling number is 0500 (that is actually translated to 2611-0500), and the called number is 6228444.

Bruno

   Cause i = 0x828100000000 - Unallocated/unassigned number

tells you the dialed number is invalid.

Chris

Chris, is this because there's something missing on my config or because the Telco is missing something?

Is this in inboud or outboudn call?

Chris

Hello Chris, this is and outbound call.

Bruno

My problem has been solved. The Telco has corrected something, they wouldn't say what was it.

Anyway, thanks for the help Chris and Alex.

Bruno
