We have a TDA50 Panasonic system at my hardware store with mostly KX-DT343 phones. A few days ago extension 102 went blank, and on the other phones the 102 light is on. The phone works when plugged into other ports. I've tried power cycling the TDA50, and also I've unplugged the RK11 plug from the port 102 plug on the DLC8 card in the TDA50. The TDA is configured with two DLC8 cards, a DLC4 card, LCOT4 card, and DHL4 card. I have access to a new DLC8 card, could it be the card is bad and that's why the one port is staying "off hook"? I am hoping to solve this myself as the installer that sold us the system is no longer in business. Thanks in advance for any suggestions!

You didn't say if you plugged the phone into port 102 at the MDF, if not do so, if phone doesn't boot up you have a bad port, if it boots up you have a jack or wiring issue.

Bingo. I had tried some other combinations of swapping jumper wires and cables, but plugging the phone right into the port works. Thank you!

In Panasonic digital, the absence of a phone will light the BLF. By default, the numbering starts at 101, so the extension for 102 is the second port in the system. That's the 2nd port, left to right, on the bottom row 4-port card (DHLC, black jacks).

So, as suggested, take the phone and a 4-pin line cord, and plug it directly into that port. If the phone lights, you have a wiring problem. You already said the phone works, so I'm guessing that's your problem.

Ah, the absence of a phone causes a light. Good to know as that had me confused as well. With everything unplugged I just assumed then that the port might be bad since it remained lit. Thanks!

Dumb question probably, but the phones require two pairs, right? One pair for data, the other for voice?

Not exactly dumb, but here's the deal. in the digital HYBRID line card, by default, the center pins are analog (as in preprogrammed for 2xx extensions) and the 2nd pins are the digital signal. All this requires programming

Thanks Carl. When I installed the Panasonic system in 2013 I remember I had to update some of the jacks since our old system required just two wires. I also had to do some crossover cables for the output of the TDA50 to our patch panel RJ11 jacks.

I am going to have to trace the line tomorrow, waiting for a tone generator to help with this as the phone system is in my hardware store which has wiring upon wiring in ceilings and beams dating back to 1974. We started with a system from IT&T, then later Southwestern Bell which was a real workhorse. We then went to an Alcatel which was overpriced and not very flexible for our needs. The Panasonic replaced the Alcatel system, and it's much more flexible and has stood up to the retail store abuse.

I have to assume that someone crimped a wire somewhere along the run from the phone to the main unit, so tracing it back will be my project tomorrow. If that doesn't work I will probably just make a new run (approximately 140') and be done with it. Just another abandoned wire in the rafters. smile
