Magix PRI fast busy

[BTU789]

Hi all, I have a customer that has a merlin magix r4. The main number and a few DID's get a fast busy when called. I haven't actually heard this after about three dozen test calls but the customer and the provider say its happening. The provider actually emailed me the error description that he gets. By the way there are no errors at all in the error log.
Here is what the provider emailed me:

03109
Key Code Range: 03000 - 03999
Software Release: 5E10 and later
Protocol: Q.931
Error Analysis: yes
1. FORMAT
PER a/a bb:bb:bb Q.931 c d e CHAN-ID-INV
[TEI=f] CRV=g CRF=h KEY=3109
2. EXPLANATION OF VARIABLES
Refer to the 03(BASE) description for a full explanation of all variables shown in the format.
3. CAUSE
The switch received a Q.931 SETUP message from the customer premises equipment (CPE) on a primary rate interface (PRI) D-channel, but the message contained an invalid channel identification information element (IE).
4. EXTERNAL EVIDENCE
This PRI call setup attempt will fail. The switch will send a Q.931 RELEASE COMPLETE message to the CPE with a cause code value of 100 "invalid information element contents" in response to the Q.931 SETUP message. A level 3 message error count is pegged and reported in part 11 of the 24 hour plant report. Refer to OPLNT24-PT11 in the Output Messages manual for additional information.
5. CORRECTIVE ACTION
Determine why the PRI CPE is not populating the channel identification IE correctly.
6. REFERENCES
Other Manual(s):
235-600-750 Output Messages

Any info/ideas would be much appreciated.
Thanks,
Brian

Since you have no error alarm codes in the Magix, there may be a problem with certain B CHANNELs. Are you configured for a full Primary ISDN, which is 23B+D? So, in the Magix configuration there would be 23 BCH in the line pool. You want to verify what is in the Magix. Have you tried doing a power up reset? You might post a print of the configuration. How long has this been happening? Can you get the list of BCHs that have the failure from the LEC? That would be helpful in troubleshooting... The email info above does not have anything specific to the trunk group or its members. More info is needed.

Thanks for the response. I didn't print any of the system info because I stopped at this customer briefly in between other service calls. I'm scheduled to be there for a few hours on monday so I'll post the info you have suggested tomorrow. Thanks again!

I,m going on a conf call with the provider and the PRI switch tech now.
Thanks.

 

[BTU789]

So, after the conf call where the provider kept denying it was a problem on their end, we decided to busyout the first trunk on the inbound PRI. I'm going back to the site at 2pm to see if the customer has had any more issues. At that point if there are no issues then the provider will send a tech with a t-bird to the site to test the circuit. I still think this is an issue with the circuit and I believe they are just trying to cover themselves. I'll update more later.

So, in case anyone is interested, a phone company tech came to the site with a t-bird and we tested inbound calls. Of course, we didn't receive a single fast busy. The phone tech said the issue may lie at the handoff from verizon to his company but on verizon's end.
But, for the heck of it I decided to swap the two PRI's to see if the board was actually the issue. I figured if the board is the problem then outbound calls would start having issues because the outbound PRI was now on the "questionable" board. This was last thursday and I haven't heard any reports of trouble with inbound or outbound calls.
Very strange. So, at this point I still don't know what was causing the issue.
The customer is happy so that's all that counts. I've been in contact with the provider and they still maintain that it was not their circuit.
Anyway, just wanted to give some sort of conclusion to this post.
Thanks,
Brian
