ta824 caller id intermittent
« on: May 02, 2016, 05:26:13 PM »
i have 8 co lines. i was starting to get this issue where one line would not register caller id. It could be line 1, 2 , 5. I restart the system and the  caller ID works again. I thought maybe it was an issue with the caller ID cards so i changed out the entire system. Its happenign again. I changed out the entire system though. Any ideas?

Is this happening on all phones?  It really sounds like a carrier issue.  We have a stockpile of Caller ID boxes in our warehouse, so if it were me I'd be putting a box on each trunk at the Demarc.  If it's happening there then you know it's not your system.

It works when i put a regular handset to the CO. The only thing that makes me feel its the unit is that I restart the unit, and the caller ID for that particular CO kicks in again...

So if you hook a test set with a CID display to the trunk (CO line), while the Panasonic is still up and working, and a call comes in, does it display on the test set even while not displaying on the Panasonic?

If so my mind is starting to go to line voltage and what is required by the Panasonic to correctly display.  Unfortunately I'm not a Panasonic tech so at that point I'll defer to our Panasonic gurus.

Yes Exactly. It works on panasonic ta824 then it stops. So if i remove the line and put it on a test set it works. Then if i reboot the panasonic and put it back on the co line it works as well. Just days later it will stop working again. The funny thing is that this has been happening for a month. I have had the same lines for years. No difference. Anyone have any ideas?

Okay, but I'm still not sure we're saying the same thing.

Do you have a Caller ID box or test set with a Caller ID display on the incoming line, while the Panasonic is still hooked up?

If so, when a call comes in, does it;
  • Display on the CID box, but not the Panasonic?
  • Display on neither the CID box, nor the Panasonic?

Can you replicate the issue?  What I mean is that once it starts is it consistent?  If so then the last step if it's displaying on neither is to initiate a call, and while neither is displaying the CID, pull the bridge clips and see if the CID magically starts displaying on the CID box attached to the CO side of the demarc.

The fact that you disconnect and hook back up could be clearing some type of inductance across the line, but we're just guessing at that point.  Hopefully one of our Panasonic techs will chime in with some answers.  I saw two of them were online yesterday.  I think Wayne said he had been out of pocket, but maybe he'll check in soon. 

What type of lines do you have?  Who is your carrier?

Without turning off the box, but a test set or CID box on the line and see if it displays on the CID box while not showing up on the Panasonic.  Personally I would connect to the CO side of the demarc.  Then if CID is not displaying on the test box, I'd pull the bridge clips, try again and see if it magically started.  That would tell us if resistance across the line or anything odd like that from the Panasonic is interfering.  It's a reach, but then you have covered your bases.

So I am ready to throw this out. The test box shows caller ID when the pbx does not. Its just CO2 and no other CO. I replaced the entire unit too, I just dont seem to get it. Once I reboot the pbx it starts working again. So odd.

have you tried swapping co lines ?

swap line 2 and 3 or 1 and 2  and see if the problem follows the line (co issue ) or stays on two (hardware issue )

I've seen this happen before with other Panasonic systems.  Just as they were getting ready to send a field technician here, I took out the solid state protectors that were on the CO lines and presto, the caller ID started working properly for every call.  For some reason, some solid-state protection devices manage to interfere with caller ID data and Panasonic systems are especially sensitive to it.

If you have these on the lines or any protectors for that matter, remove them.  They aren't necessary with FiOS anyway.  See if that causes any change.

What are solid state prevention devices? I dont think I have anything? This is a huge problem as its a hit or miss and im running around like a maniac trying to solve this issue. Thanks

Solid State Protection Devices are installed (often by the Utility) where the circuit enters the building. They are designed to shunt lightning strikes to earth and prevent damage to personnel or equipment. Earlier models were not Solid State devices, but were rather carbon blocks or gas tubes.

Sometimes you'll also see what looks like a demarc that is really a suppression point that has been installed by an interconnect. In that situation the suppression device goes where the bridge clips would normally go on the block.  I suppose you could test by taking a box of wire and running from the cabinet all the way to the drop point.

I will say that if Ed says he has encoiuntered this on a Panasonic, it's well worth your time to check it out thourougly.

You lost me. So I should have verizon check the demarc? I basically have an ONT box outside the building and then from there it is ran inside the building to where my panasonic box is. Would I be able to check or would the phone company have to do this?

Check to see that the wiring for the phone lines go directly from the ONT POTS line terminals to the Panasonic line jacks. Sometimes the techs will cut corners when they installed you and re-use part of the old wiring which could have had a protector someplace in the line. I've found them buried in walls and ceilings at times.

If you find that the wiring is correct you might want to check the loop current for the affected lines, but other than that I'm afraid you will need to chalk this up to an incompatibility or a problem with the Verizon ONT where the CID carrier is generated. If you have another Panasonic ta824 KSU I would swap it out with the existing and see what happens. Depending on the results try and get Verizon to swap out the ONT.

I spoke with one of our moderators here yesterday regarding the same issue he was having with a Partner ACS behind an Alcatel/Lucent ONT that the LEC was using.  CID would show up on a single-line set connected directly to the test port, but not on the system.  We tried all kinds of things, to no avail.

As a last-ditch effort, he disconnected the power from the ONT itself (not the power supply inside), he disconnected the power and reconnected it to restart the ONT.  Voila!  It started working.  I'm sure that we're not supposed to do this, but when you're being told that it works and it doesn't, what choice do you have?

Despite the fact that the LEC swore that there was nothing wrong, they weren't 'really' testing it.  As with most hardware, sometimes a hard reboot is what it takes.  In this case, it did.
