I had a customer call me last night reporting that his phone system "crashed". When I called him back (on his cell), he said he had already power-cycled the system, and that didn't help. I had him test for intercom dial tone. Intercom calls worked. However, when he pressed any line buttons, the LCD said "Disabled". I walked him through power cycling again, just to make sure it was done correctly, since the system has a battery backup installed. When I arrived onsite this morning, 4 of 14 lines worked. The others still said "Disabled". Apparently, the 4 lines that worked this morning also said "Disabled" last night. I logged into VMMI and checked programming. None of the ports were actually disabled. I used VMMI to disable all of the C.O. ports, then re-enabled them. This cleared the problem.

Any ideas? Do you think this is something I'm going to see again? I'm thinking possibly some sort of database corruption.

The system is a FXS-112. Feature Set 15A, Maintenance Release 180.

C.O. Board is a FXLST-16 (slot 4).

This just recently occurred again. Another problem at the same site, maybe unrelated, is that the customer reported at least a day's worth of trouble with calling out. Apparently not all digits were going out correctly, because the C.O. kept playing a "We're sorry, your call cannot be completed as dialed..." I went onsite to troubleshoot, but was unable to duplicate the problem.

I'm beginning to think I either have a bad board, or a corrupted database.

If I replace the board (FXLST-16), I can't remember whether or not I can replace the board with a FXCMW-16? Software is 180, but feature set 15C. I looked for the document from when the FXLST-16 was discontinued, but couldn't locate it. I seem to remember something about using it as a FXLST-16 in the system, and that it would work, but without the CID and CMW functionality. Does anyone remember?

Also, what about the corruption possibility? Has anyone seen this before? If it is corruption, do you think I would need to completely reprogram manually to clear it?

Thanks!

Okay, now I have phantom ringing on 2 of the ports on the FXCMW-16 card. The problem stays with the port when I swap lines. I'm now wondering whether it's a bad (out-of-box) FXCMW-16 or that it's just not compatible on the FXS. I have the board assigned as a FXLST-16 in the system. Can't remember if I mentioned that before.

We are still trying to track down the intermittent problem with dialing out. We don't have much more information, but it does seem to happen more often on line 3 and with numbers that contain the digits 7 and 8. This isn't the rule though. I think the line 3 thing is just because that's the first line that's accessed by the line group. We are going to still check line condition with either a Sidekick or something similar. Short of trying to capture digits using a digit grabber (ours won't capture anything more than 1 row of digits worth on the grabber's LCD) ahead of the FXS, I was wondering whether the black box would report information on actual DTMF generated out on the line. I guess at this point we are trying to determine whether the problem is in the FXS' DTMF generator going out, or in the central office's receivers. For the time being, we have increased the DTMF level going out to see if that makes a difference. BigDog, can you answer the question on the black box? Thanks!

The Black box will show you the digit being pressed from the staton, not what is being sent out the analog line.

What is the layout of the system, are you using ARS or just accessing a line group directly?

If using ARS do you have the problem if you turn it off? How easy is it to duplicate?

If using ARS does the line give you dial tone right away or does it miss the first digit do to late DT.

These can be tested with a test/butt set.

When will you be onsite again, If I am available I will try and help.

Just using the lines directly. Everyone has line appearances on their phones, so no ARS. We still haven't been able to figure this one out, but it may end up moot if they decide to replace this FXS with a MP5000. Then I'll get to start a whole new thread.

Thanks for the info on the black box though. It doesn't sound like it would give me any more indication than I already have, based on this specific problem.

I've had a defective ScoutII cause intermittent dial out. Finally tracked it down by turning on SMDR & having the data sent to my laptop overnight. Replaced the phone & problem fixed.
