Partner 34D Speakerphone Issues

[bayshorellc]

Hello,

I am having an odd problem with a partner system that I installed for a client. I have installed several partner systems over the last six or so years and I have this problem that is just got me stumped.

The system is a 7.0 with 3 - 308's and a Partner Messaging. All but 4 of the telephones are 34D's. Those 4 are 18D's. When the users are intercomming each other in thier offices over the speakerphone. The caller who initiated the call cannot hear the person they called unless that person either a.) Yells directly into the phone, or b.) Slams thier fist down on the desk. The MIC/HFAI button is lit at all times. It seems that the Microphones on these phones are not sensitive enough to pick up the voice of the respondent. Also let me add that they have issues as well when they are using the speaker phones for outside calls as well.

Has anyone else encountered this issue? I have replaced the ACS thinking that it had some type of glich or something, I have checked everything I can possibly think of as far as programming. I have a ton of these systems out there and no one else has ever had this issue. However with that being said this is the only system I have deployed with this many 34D Telephones.

Any help, Insight or Opinions on this would be much appreciated.

Thank You,
Jason Thompson

I don't think I've seen this problem before.

High ambient noise levels can cause problems for hands-free users. One option would be to mute and unmute the microphone as needed (a real pain, but it might help)

There may be a limit to the number of 34Ds you can use on a given module without causing problems as the 34Ds consume more power than 18Ds.

1 quick way to find out if the problem is load related would be to unplug, say, all but (2) 34Ds from a given module and see if that makes a difference.

Yes I initially thought it was a noise issue as well. But I went there myself after hours to try and duplicate the problem and it was quiet as it could be. I moved the phones around on the desks trying different placements, etc. It is definitely not a noise issue. However the second part of your post brings up an interesting point. I will have to try that this week when I go back onsite. If it is infact a load issue I am assumming that there is no fix for it.

If the problem clears by reducing the number of 34Ds, Touch Tone Tommy gets the kudos.

He did mention that there is a limit to the number of 34Ds that a 012 can handle, but he didn't have the exact figure readily available when he posted on my thread. His observation may also apply to 308 expansion modules.

The 34D power issue pertains to 012 cards only. I can't find the cite, but it was in an Avaya Business Partner newsletter some time ago. You can read a little in the R7 pdf manual, look in the index under 012 and power management.

I have a Dr.'s office with an 18-D in the records room. The microphone just doesn't work well on HAFI. I thought I had it licked by enlarging the hole where the microphone sits, but no good. Also swapped it out with an MLS-18D, where the mic is on top instead of the bottom of the set. Still no joy. They seem to have to holler to get it to transmit, at that point why have an intercom at all?

Please let us know what you come up with.

Start with the basics, Is the power outlet giving you the proper levels. Check the ground, plug the 34D's in one at a time and test.

Pull the 308's out one at a time, and test, it could be a module or a phone with an issue causing a system wide issue. Test every component for the cause of the issue by eliminating it. I know it sucks, but do it by the numbers.

You do not always get what you pay for, but you never get what you do not pay for.

OK well I went this week to this customers site and ran a few tests. I unplugged everything except two 34D's and it worked great. I added 4 18 D's and there was no problem at all. I added 9 34D's only on the 7.0 ACS and the problem started all over again. So with all of that I am assuming that this means that it is a load issue and there is nothing that can be done to resolve this issue.

It appears that the power supplies in Partner ACS modules, (processors, 308 and 012E), cannot support a heavy complement of 34D telephones.

Avaya states that loading up a 012E with 34Ds can cause problems, but now it looks like other modules can have problems when a large number of 34Ds are connected.

Unless some of the extensions can be scaled back to 18Ds, it looks like the customer will have problems using the hands-free feature on the telephones.
