Topic: ta824 caller id intermittent

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.
