Nortel CICS - Disconnect Supervision Issue

[carpediem222]

Hello All-

My customer has a Nortel CICS with a Call Pilot 100. I recently replaced both line cards in the system with the exact part number/version. The customer is now reporting disconnect issues when a caller leaves a voicemail. When the user checks their message the loud off hook tone plays after the message finishes. I ran a test call and after leaving a voicemail, it took 50 seconds to release the line.

When using the lines to place and receive live calls, the disconnect works correctly. I am only experiencing this issue when the call goes to voicemail.

Any help would be greatly appreciated.

Thanks in advance.

-I wonder if a certain rls of that part number is the issue (which is what part #?)
-What version software is the CICS?
-What version software is the Callpilot?
-Why were both cards replaced?
-For sure DS is programmed for all lines in question?.
-Do another test call but use a set, call with cell phone into system and answer the call

There is a DISCON setting under the card in Hardware programming, try each timer if need.

How are you testing this? If you don't have an OHM meter to actually test the lines then the next best thing is to have someone call in.
You answer the call and put it on hold.
Then have the person that called hang up.
You should see the call you put on hold drop after a couple of seconds.
If it does not drop then your supervision is either not on or not working.

Curlycord/Hawks - Thank you for helping out. I tested the disconnect by calling in and placing my call on hold.. I disconnected the call to see if the line was still held open (like it does for the voicemail system) and the line drops the call, as it should. Any ideas?

did you check every line? It could be just 1 out of the 8 that is giving you issues. Also like like curly ask why were the cards replaced in the first place?

The reason for the cards requiring replacement -

The customer had numerous CO Line ports out of service, at this point, they had run out of usable ports and majority of their CO Lines were inaccessible. Replacing the cards corrected the dead line port issue. The customer waited 3 months to report the issue (after the 30 warranty period), and are now wanting the issue resolved.

In the interim, I will have the receptionist check each line to ensure disconnect supervision is working on all trunks.


Thanks for the help.

One other thing if they are the Global CI cards then I also know there are some dip switches on them so make sure they're set for North America. I ran into that a few years back when a cust had me install you they got on ebay from overseas.

The receptionist checked each line and found the following: Lines 1/3/4 are not recognizing the call disconnect. Line 2/6 are working as they should. Any suggestions?

Test them at the D-mark with an Ohm Meter.

Swap line 1 and 2 (or line 4 and 6) at the demarc then do a test, does the problem follow the line moved or stay with the line position? If the problem moves the issue is with the service provider. I would try several calls, preferably not from a cell phone to confirm the issue.
