sundance-communications.com/forum Forums TDM Business Telephone Systems Avaya - Lucent Telephones & Systems Partner R7. Phone lines keep locking up

Didn't know if anyone else is having this problem. I have a customer who we installed a Partner R7 with R7 VM. About once a month all the lines lock up, so when you look at your phone it appears all the lines are being used. The customer manualy has to hit the line button to free up the line. If a caller calls in when the buttons are all lit they get a busy signal.

Might try resetting the system. #728

Man, I just got through changing out an R6 with an R7 for the same issue. Except even though I removed privacy, and you could barge in on the in use line, you couldn't release it without resetting the system.

sorry .... again, need my pad adjusted!

are they using remote call forwarding?

there is a known problem with rls 7 and remote call forwarding that locks up system. i just got the patch sent to me from avaya.

sorry, new laptop and need to get pad set right!

We do have remote forwarding set up on a couple of exts. I will have to look into that patch. Thanks for your help.

This might be totally off-subject, but have they changed local dial tone providers lately? It sounds to me like your problem may be as simple as not receiving disconnect supervision on the CO lines.

We have see this happen on other brands of systems, usually during night hours where the voice mail or auto attendant answers all calls. Since disconnect supervision isn't being received, the voice mail ports don't ever release the call and you end up with all lines lit up. Maybe next time it happens, you should check to see if the voice mail ports are locked up at the same time.

We have seen this loss of disconnect supervision even happen with existing customers who don't change providers. The LEC just rearranges some equipment in their network and it just goes away on it's own.

How come there's always enough time to go back and fix it a second time?

Just as a side note, most older CO's with Centrex switchs are not capable of providing a disconnect signal. It was not needed for the equipment sold at the time. Just something else to look out for. I also have seen disconnect signals not reconized on upgrades to Magixs from older Legends without reversing the polority on the lines.

Gkar:

Beg to differ with you there. 1A2 equipment which dates way back to the early sixties had option straps on the CO line cards to select the length of the supervisory disconnect signal.

Mechanical CO switches (Panel, SXS, Crossbar, etc.) always had supervisory signaling to drop a "cord board's" mechanical hold circuits. This was in an effort to reduce the number of trunks required into a customer's PBX (cord board).

Electronic switches (ESS, DMS, ESWD, etc.) were developed later when the end-user equipment could not be guaranteed to be made by the same manufacturer. In the late sixties, it became legal to buy key systems and PBX's from manufacurers other than the phone company's CO switch manufacturer. The telephone companies had to provide the necessary compatibility with regard to signaling.

Just to play it safe, when the electronic switches were developed, the manufacturers set the supervisory disconnect signal "just a little bit longer" so that their signal worked with the new slew of customer-owned systems from all over the world.

Back to 1A2; the settings (a physical wire strap) were "short" for crossbar offices and "long" for ESS. Loop supervision has been a major part of the POTS line business for decades. I am not sure where you got your information, but it's not accurate by any stretch of the imagination.
