I have customer with a STSe 4X8 that has been in service for about a year. I recently relocated their system to their new office and reinstalled all new wiring from the demarc in and to all stations. About 2 months after the move they started complaining about a low volume on one CO (line 2) on all phone sets. They have a hard time hearing the callers and if the call goes to voicemail it cuts off in mid message while the caller is recording thier message. Had the local telco come out and check the line and it tested good. When I check the line with a butt set it sounds good at the end of the amphenol connector to the system. I have checked all volume controls on the phone sets and have reset the system several times. Any ideas? I would hate to have to replace this system over a low volume trunk problem. :bang:

Unfortunately, this is a fairly common occurrence with the STSe. Line ports fail for no apparent reason. Before you do anything, you should try reversing lines 2 and 3 to see if the problem stays with the port itself. If it does, you have a few choices:

1) Not really an option....Send the KSU out for factory repair since it's probably still under warranty or;

2) Move the line to an unused CO line port and map it over to the appropriate line keys or;

3) Add an LCOB card and move the line to a port on that, then map it over to the appropriate line keys.

Sorry for the bad news, but there's no easy answer. Rest assured, you didn't do anything wrong when you moved the system. It's just a coincidence.

Have you toggled the Loop Length setting under Flash 41 to see if that helps? i think by default the setting is set to short.

But i also have seen the same situations that Ed has seen.

Unplug the CID module and plug it back in.

Did you find a fix for this? I have a customer whos employees say they cant hear very well on this new STSe system. To me its just fine. I talked to Vodavi Tech Support and they said in WinDBA you can actually turn up the volume of the CO line. Has anyone tried this or know of any other solutions?

Yes,that was one time i did have a use for WINDBA.
Had a inskin vm on a STS which was reporting cut offs,
drop calls on transfered co lines to vm boxes.

There are some co line settings to handsets, speaker phones etc.

Seems like i changed three settings, being careful
not to overdrive the trunks.

I think i moved the settings a couple DB at a time.

Never had any more complaints from customer.

Guys, does anyone see a problem here? A phone system should be able to be connected to standard CO lines with no modifications whatsoever. No different that going to the store and buying a $10.00 phone.

Why do we continue to tolerate the shortcomings of our telcos not providing industry-standard and regulated dial tone standards? Why do we keep trying to fix problems on the equipment end instead of insisting that the telco meet minimum delivery standards?

People seem to think that since the newer systems offer "adjustment" capabilities, we should solve the problems on our end. It is not our responsibility to adapt to the telco's problems. They must provide consistent line quality levels as a regulated utility.

We need to quit tweeking line settings, buying "gadgets" to overcome their out-of-range measurements or just beating our heads against the wall.

Ed that sounds great and I completely agree with you but really they got us between a rock and a small place. We can complain to the provider all we want but in the end it will fall on deaf ears!

Correct ED, it was a telco issue, and i agree the
system settings should not have to be modified.

I just don't fight city hall anymore.
