DPQ3212 DIGITAL PHONE SERVICE AND PANASONIC TA624

THIS POST WOULD PROBABLY APPLY TO ANYONE HAVING A PHONE SYSTEM IN THEIR HOME. MINE IS A PANASONIC KX TA624 WHICH HAS WORKED FINE FOR 10 YEAR. COX GIVES ME THREE INCOMING PHONE NUMBERS (TRUNK LINES) AND THE PHONE SYSTEM (SWITCH) SERVES IT OUT TO 16 PHONE STATIONS IN DIFFERENT ROOMS AND LOCATIONS. EACH PHONE SHOWS ALL THREE LINES SO YOU CAN PICKUP IN ANY ROOM, AND THE PHONES HAVE CONFERENCE CALLING, INTERCOM INCLUDING FRONT AND REAR DOOR, AND MANY OTHER FEATURES.

NOW I'VE BEEN TOLD THAT I MUST INSTALL THE DPQ3212 FOR MY PHONE SERVICE - I WILL NEED TWO UNITS BECAUSE THEY ONLY HANDLE 2 LINES PER MODEM - AND I MAY GET CUTOFF ANY DAY NOW BASED ON MY LOCATION.

NOBODY AT COX CAN TELL ME (SO FAR) IF THE OUTPUTS LINES OF THE DPQ3212 ARE COMPATIBLE WITH MY PANASONIC INPUTS SO THAT WE CAN JUST PLUG THEM IN OR WHETHER MY WHOLE SYSTEM GOES DOWN WITH NO SOLUTION IN SIGHT. THE TECHNICIAN WHO CAME OUT THE FIRST TIME TO INSTALL THE MODEM STOPPED THE INSTALL AND SAID IT WOULDN'T WORK WITH MY PANASONIC.

I TALKED TO RESIDENTIAL SUPPORT SEVERAL TIMES AND WAS LEFT WITH THE IMPRESSION THAT THEIR SOLUTION WAS TOSS MY PANASONIC AND CONNECT UP A COUPLE OF PHONES IN A ROOM OF MY CHOICE - ONE PHONE FOR EACH OF THREE INCOMING LINES AND BE SURE TO REMAIN IN THE ROOM THAT I WANT TO USE TO ANSWER THE PHONE.

JUNK MY PANASONIC AND 16 STATIONS I'M CURRENTLY USING AND GIVE UP ALL OF THE FEATURES WE USE.

I SPOKE TO COX BUSINESS AND THEY SAID THEY DO NOT HAVE A SOLUTION FOR ME TO GET THE SAME FEATURES USING THE RESIDENTIAL NETWORK. THEY HAVE OTHER NETWORKS AVAILABLE ON BUSINESS LOCATIONS THAT THEY DON'T HAVE ON RESIDENTIAL.

1. CAN ANYONE TELL ME WHETHER IT'S TRUE THAT THE DPQ3212 AND THE PANASONIC WILL NOT PLAY NICE TOGETHER?

2. CAN ANYONE CONFIRM HOW MUCH TIME I HAVE LEFT BEFORE MY WHOLE SERVICE SHUTS DOWN?

3. CAN ANYONE SUGGEST WHAT TO DO IF #1 ABOVE DOESN'T WORK?

  • they're going to feed the modems right into the box outside the house where the old NIU dropped out the three lines.

    I found a post that talks about what you are talking about. See full post here.

    " With the old wiring, the line went from the demarc to the alarm panel which would have a RJ-31 jack.  The line would go into the alarm system on pins 4 and 5, and come back out on pins 1 and 8 to return to the house wiring connections by the demarc.  By moving the demarc to the modem, wiring for the alarm would need to go on a dedicated pair from the modem back out to the old demarc, then to the alarm and house wiring as before. "

    I just don't understand how there is still a phone demarc AFTER they remove the NIU. A box with a RJ-31 jack in it? What is the box outside that it goes through? Sounds like they did everything right, I am just trying to better understand the solution. As you can see, most telephone technicians just don't have the experience for this kind of thing. You are kind of in the middle of having better phone equipment then your average user, but without the IT support of a big business. Thanks for taking the time to document the solution.

    Does that mean this thread can be marked resolved? Have you tested everything?
