Partner 7.0, T1 module and "background hissing" noise...

[xjswx]

Wonder if anyone has experienced this...

Partner ACS 7.0 with T1 Module, when you go off hook and grab a line to make a call, all that works, but durning the "dead air" time from when you grab the line and actually get dial tone, it sounds like "battery only" before the dial tone hits. Then once the call is connected it sounds fine unless noone talks... then you hear that "battery only" or hissing noise again.

Anyone ever experienced this and if so any resolution? I have the T1 vendor looking into the T1 programming... the only adjustments I can see in the actual T1 programming on the switch is the Line Build Out where you can change the db settings.

Any feedback appreciated.
Thanks.

Never installed a T1 card on Partner but is there an option for silence suppression if so change it and try it.
Probably not much help but worth a shot.

There is an option to change the Line Build db's. I wonder if that will help?

I will also check for silence suppression today when I am on site.

Westi-

no silence suppression. Changed the Transmit Line Build Out for 0 dB to -7.5 dB... made no difference.

I've never crossed paths with the T1 module. My understanding is that it is not widely used. Customers needing T1 service can usually get bumped up to a Legend or Magix.

Can you swap out the T1 module or processor with a spare to see if it makes a difference

If it ain't broke, I haven't fixed it yet.

damn this thing is such an odd occurrence that I guess Avaya only sold a handful of them, I don;t have any other ideas but what Dexman said swap hardware and test, or if you happen to have an IPO around with a PRI card hook that up and test with that so you can eliminate the line provider.

The Partner ACS is aimed at a market that probably doesn't need T1 service. That, plus the fact that you cannot use all 24 channels for voice, makes the T1 module a bit of an oddball.

IF Avaya does ever offer an R8 processor, they might want to look into giving it the ability to accept a full T1.

If it ain't broke, I haven't fixed it yet.

Dexman, we heard full Pri

A full 23 "B" + 1 "D"

Ya. I changed the Line Build Out to -7.5 dB and the customers says its better. I'll let it ride for a few days and check in with her to see if its acceptable the way it is. If not I'll try bumping it up.

No I have not replaced any of the equipment yet. I believe we inherited this problem. It is an early version of the R7, so maybe it's the proccessor.

It's weird because the problem is only on one phone, and intermittent. And I say phone, not extension because we changed extensions, changed phones, and no matter what.... It still happens to this one particular user... maybe he has dog ears and can hear things humans cant. lol

And as far as a T1 on a partner... I agree... there should not be one. A magix would have been a better choice...

The system config is: 1-ACS R7, 1-T1 Module, PC Mail. (Kinda small for a T1)

 

[Dexman]

Don't get me wrong. If Avaya made the Partner ACS so that it could accept a full T1, then I'd have no qualms.

Now with the Merlin Magix in retirement (but hardware is plentiful in refurbished form), this is the time for Avaya to pull itself together, get the bugs out of the ACS and market a top notch entry/mid-level telephone system.

If it ain't broke, I haven't fixed it yet.

The Line Build Out (LBO) for DS1 service has NOTHING to do with what rides the DS1 facility!! It has ALL to do with the equalization of the digital signal levels between source and destination.

A simple definition is: The process of adding a combination of inductance, capacitance, and resistance to a cable pair so that its electrical length may be increased by a desired amount to control impedance and loss characteristics.

You need to separate what "rides" the channels verses the facility that carries the channels. They are very different animals!

In regards to the PARTNER equipment using DS1 service in any "real" configuration, Avaya will need to deal the DIAL PLAN ISSUE first before ANY expansion can take place! The current configuration is stupidly limited and a waste of money!
