Partner Line noise/crackle

[jbrots04]

I have a Partner system that is making a crackle/static sound on the lines. It is happening sporatically on all lines. I've had the phone company on-site to ground and test the lines from their channel bank. They are not hearing any noise when connecting to the lines directly from the channel bank.

Does anyone have any idea what the problem may be with the phone sytem?
Does anyone have any further troubleshooting suggestions or solutions?

Thanks,
Jeff

That's a tough one....Is the electricity in the building sound? Are you able to remove a module at a time to see if it is coming from a specific card? If you hook up with a butt-set before the switch, do you hear it then? Is it a 5-slot carrier or a two?

The power does go out in that office frequently.
It's happening all lines [modules].
The phone co tech used the butt-set before the switch, and didn't hear any noise.
It is a 5-slot carrier.

Thanks,

I would still try to remove the modules on a one-at-a-time basis and monitor it that way. One bad module may cause interference on all lines, if I am not mistaken. Or, try pulling the processor out of the carrier and make calls on the available dialtone(lines 1-3). See if it continues that way. It's possible that it is a carrier issue, too.

I agree with FoneDude66. Have you tried the intercom with the dial tone broken? Try to pull the VM card first and check. I have had two systems with the same fault. It was the VM card in both cases. Different releases.

Although you won't find many Avaya dealers admit this, the Partner system will start to crackle and pop after a couple of years. This can be stopped, by replacing the module that is causing the issue. Generally I see this most on ext.10 and lines 1-4. I think it's due to the amount of use. Remember the Partner system is analog (featuring a digital/modem pair). If you system was digital (Norstar, Magix, Legend, etc.) you would not get this problem.

I must say that the crackle is true of 206 type cards. I haven't see this with the 308's yet. A system in a hot enviroment will accelerate this.
With digital ports, you don't get crackle, you get dead or flakey ports. Same thing only different. On other systems on an analog port, you get similar and really bizarre faults (Legend / Magix included).
I guess I'm defending the new Partner cards a bit. Besides, we are talking CO ports I think. Not nearly so problematic even with old 206's

That crackling may be your expansion mods (206 or 308) going bad. Board level changes might be the only thing needed to repair this problem.
