Testing a PRI circuit 4

[phnechic]

We had a PRI circuit added to a location today. A test DID number was set up. The last 4 digits of the number are passed to the PBX. We configured the last 4 digits on a set and tried test calls, but the PBX keeps rejecting the calls, indicating "unassigned number". My config follows. Any ideas?

Here are the DCH messages I see when I try to call the test number:
DCH 11 UIPE_IMSG CC_SETUP_IND REF 00000500 CH 8 1 TOD 14:58:06 CK 3C1F4DE3
CALLED #:1643 NUM PLAN: UNKNOWN TON: UNKNOWN
PROGRESS: CALL IS NOT END TO END ISDN

DCH 11 UIPE_OMSG CC_REJECT_REQ REF 00008500 CH 8 1 TOD 14:58:06 CK 3C1F4E02
CAUSE: #1 - UNASSIGNED NUMBER

Test number ends in 1643

Assigned 1643 as the DN on key 00 of an M2616

Court,

Try turning signaling on and off on the D-Channel. This would be in LD 96.

This is not the MSGI on the D-Channel, rather an actual signaling services on the D-Channel. I had to do it when we turned up the PRI's at CORP, so this might be all you need. I don't remember the actual command, but it should be in the NTP.

Good luck, and you know how to reach me if you have any other questions,

Scott M.

 

[johnpoole]

enl serv dis serv, are the commands

is this the 1st pri on this switch? if so did you tell the switch that you want 4 digits tone?

Thanks for the assist JP. It would be the first PRI for this switch, but it has always had 4 digit via analog DID and MCDN PRI's between other switches.

This is a project the my previous employer is working on, as well as a project I started; at least in the planning stages.

Scott M.

 

[phnechic]

Thanks to both of you! Yes, Scott this is the project just as you left it....I'm just working on the implementation. I was able to get the test number to work by adding an extension into LDN0. You guys are great, and I really appreciate the quick response. You are like the dream team of technical knowledge!

 

[lretrievers]

What is LDN0 set to in the Customer Data Block. If you are resolving on 4 digits, you have to have a 4 digit number (any 4 digits will do) in the LDN0 prompt in the CDB.

 

[johnpoole]

analog did's do not use that field scott, good to see your alive and well, if you have time could you post a faq on your finding on path replacement problems? been a couple of tough ones come up on that lately and i haven't been able to locate your past post on that issue

[iptuser]

Nearly always the unassigned number is that Nortel is being sent a number it does not recognise or configured, is the other end really sending 4 digits or may 5. Check in D- channel messages and look for the incoming number

 

[srmega41]

JP,

I added a FAQ that goes over as much as I could think of early on a Friday regarding path replacemnet, Q.SIG and the D-Channel settings. Please add anything you feel is missing.

If the LDNO is set incorrectly on a PRI DID span, will that cause D-channel negotiation to fail? I am seeing the D-channel come up for 20-40 seconds and that and then the CO releases the connection (RLS REMOTE).

I have verified the usual suspects, B8ZS/ESF, IFC=NI2, 23B+D, COT=ATT (tried STD as well - the switch is the model that came after the ESS5)

 

[lretrievers]

Yes.....if LDNO is not the same number of digits you have as DNs.....the call will fail to terminate correctly. So if you are using 4 digit extension numbers, you need a four digit LDN0 (doesn't matter what the number is, the length of the number is what matters). If you have 5 digit extension numbers, and your numbering plan works to look at the last 5 digits of what is being sent, then LDN0 needs to be 5 digits long.

 

[marcuswelby]

Thanks lretrievers.

Another question - even if the length of the number is wrong, I understand that the call will not terminate correctly, but the mismatching lengths will not have an effect on D-channel negotiation, will it?

Cheers,

John.

 

[lretrievers]

D-channel negotiation as far as the signalling going on should work; what typically happens on the mismatch of LDN0 is D-channel messaging comes across with a call rejected.

 

[marcuswelby]

Thanks again lretrievers!

 

[lretrievers]

no problem.....glad I could help.
