internal communication crackling noise (pop corn)

[DigitalG]

system ip office v2 7.027
ground is good
all lines are tested

phones T7316e and 1408

sometimes i hear crackling noise like pop corn with internal communication.

Do i have to replace the unit or the combo card ?

your guess is as good as ours.
You have to start with something and go from there but you have either TCM cards as well as Combo cards or expansion modules for the Nortel sets and have to try one or the other to traoubleshoot it.
See if the Combo card is an old vintage and if so replace it as they might have more issues than just the line problems.

It sounds like analog trunks on a combo or ATM4 card.
Like Westi says, check the PCS level of those cards.

I'm not insane, my mother had me tested!

my issue is not with outbound communication, its only internal communication.

 

[tlpeter]

Is it from DS8 to TCM8? or only one of those cards?

im going to the customer tomorrow and i will test a phone (both t7316e and 1408) directly into the ipo.The noise can come between any type of phone avaya or nortel. and its not always on. it could be the battery backup ?

We are experiencing feedback on our T7316e phones, but only when its an external call on our POTS lines. We changed out trunk card and no luck. The feedback we are hearing only comes from our end, the caller can't hear the noise. If we use speaker phone, its fine. Unlike you problem, if we call internally, its fine, no feedback.

We tried changing to Avaya 1416 phones, but the firmware update keeps erroring out.

We've had AT&T out to check the line quality, they keep saying its fine. I'm lost on my options. I noticed today there is a quarterly update out, I'm being advised to run it to bring us from 8.0.42 to 8.0.43. I'm not holding my breath.

Firmware update issues is the sign of an older and probably dodgy combo card, is that what the lines come in on? Or did you try the 1416 in the same port as the T series phones? As that will not work (although it was supposed to happen with R8...it didn't)

 

[mdust]

No, we didn't plug the phone into the same port the T7316e phones are plugged into. Our slot 1 on the IPO has the combo card - ports 1-6 are digitals, 7-8 I'm not sure, and 9-12 are our POTS lines 1-4.

Could that combo card be the cause of our feedback issues?
