MSG waiting light woes

[albiej]

I have an Octel 250 with SW 3.11.05-1.
I have been having a problem with (analog only sets)ie AAsta 9316CW phones. Since installing hundreds of these that replaced Nortel 8009's and 8314's the message waiting light either does not light when there are new msgs or it is lit when there are no MSGS. Problem clears on its own with little intervention. A new message will sometimes clear up the problem for a while. Looking through some of the patches that Avaya offers I came accross a patch that looks like it will fix the problem. Has anyone had a simular problem and had this patch fix it? What do think? The link to the patch is below..

My 250 has FLT-N'S not the DMID's that the patch refers to. So I guess that patch does not apply. Any more ideas?
I have a Nortel 81C.

What does the online CDR show on the MB for the user? If a new message comes in you should see the Octel turning on the MWI for that user. How many ports do you have set to turn on MWI and how many users on the system?

Theres about 350 analog users. Two of the 24 ports are for MWI, just MWI, nothing else. The problem only happens for analog sets. No problems with digital sets. Like mentioned above, this problem started after upgrading existing Nortel 8009's, and 8314's to 9316cw analog sets.

By the way I changed the MWI ports in thePBX to new ones and that didn't fix it.

It's not a select few that have this problem. There's a bunch. Maybe the Nortel PBX needs a patch to allow the 9316's to work properly.

I've tried to capture the problem in the CDR in the Octel, but every time I try to see it happen, it works without failing. If I happen to catch it in CDR, and I don't see the "msg wtg set, clear" come up when it should have, where would the problem be? In the PBX?

It sounds to me like the power drain on the PBX to light the lights is the problem. They are all analog sets so it takes 80 V to tuen the light on per set. You may not have the right power supplys or bad ones.

And if all of the non analog sets work fine then i don't know what else it could be.

Thanks Ken,

I'll have to check out if the failures came off of the same PS shelf then.

One more question: If I don't see Mwi set/clear come up on the Octel cdr when it should have, does this mean that the PBX is at fault for not sending the command to Octel, or the Octel failed to respond to the command from the PBX?

 

[KenMeans]

You should see it when a new message is left in the mailbox and when the mailbox is clear of new unheard messages in the CDR. If the CDR is not showing it then i could be the Octel not sending the info to the PBX.

Are you never seeing it on the CDR?

I see it in the cdr. I don't know what happens when it fails though. Hard to catch as it happens. Sometime the MWI is on when there are no unheard MSGS and sometime MWI won't go on when there is a message waiting. Different users complain that they had say 10 msgs in the box but light did not go on.

 

[KenMeans]

If you see it in the CDR then the Octel is sending the command to the PBX to turn it on and off.

Are all of the Analog sets on the same shelf? It still sounds to me like a power issue with the MWI lights on the analog phones.

What Model Nortel are you using?

No not all on the same shelf in the 81C. I've had problems on loop 4,8,and 20. No probs on loop 24 and it does have analog tn's. I posted this problem in the Nortel forum also that will give you more info on this. I am starting to see a pattern that I describe in the other forum.

Ken,
I have a 48 volt dc pbx. That 80 volts to turn on the light that you mentioned earlier, does that apply to my switch? Also is that 80 volts DC or AC?

 

[KenMeans]

It may not be 80 on your system i know on NECc it has a sep 80 V power for the analog lights. If the trouble started with the addition of the new analog phones the only thing that makes sense to me is that the phones are drawing to much power when you have 300 or 400 turned on not sure.

The phones that these replaced were also analog with MWI's, just not the same model.

Thanks

It could be the new phones. I had a similar issue once, the lights on the phones did not always work. If you plug in a new phone, then the light would come on. I would check the phones, since the problem started after you swapped them out.

I don't know why the administrator didn't upgrade to simple digital sets in the first place. All the existing digital ones never fail. I'm pretty sure the PBX service vendor will be looking into a patch or something from Nortel real soon.

Thanks
