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?
Thanks. Talked to Cox Business. They rely on a different network according to them and would not have any solutions different from this on the residential network. Looks like it comes down to whether the DPQ3212 output lines will be compatible with the KX-TA624 incoming trunk lines. The last installer who came out seems to be adamant that it wouldn't work.

Yea, that's BS. Who did you talk to over there? I have seen phone modems with as many as 16 lines in CB. I think your showed them your PBX and they got scared. Or maybe they thought you were asking for POTS instead of Packet Switch, which both services use. However CB uses it in a much more robust way.
I don't see what the problem is on the Resi side though. Should be as easy as having t phone modems. How the phone connects to the PBX might need to be changed, but it may work plug and play.
Outside line CO interface is RJ-11, so just plug the lines from the modems straight into the KSU just as before.
Thanks for the insight.
Today I had scheduled at Cox recommendation the second installer who was to put in the modems. He called from the road and once again informed me that the DPQ3212s would not work with the Panasonic. The time was in January when the installer actually came to my house and then told me that. This one didn't even come out.
So a few hours later another technician showed up from Cox (not a contractor) and he said he had installed modems before on Panasonic and they worked.
DWARD - as you suggest - it's just as easy as plugging the modems RJ11 into the CO lines on my Panasonic.
NOW remember the only reason we're here is that two successive installers have told me the DPQ3212 would not work with the Panasonic.
NOW the reason you want to make extra sure about this is that once they install and provision the modems in the central office there's no going back. If it doesn't work and your whole system is down, you're SOL. I'm not sure what I will do after that - I'm not that familiar with alternatives to COX. Been working with them with their phone services for 12 years and paying $100/month+ for three lines. Do I have options? I don't know.
But they agreed to setup an installation where they will bring in a phone expert who knows all about phone systems - Panasonic appears to be about 75% of the market - and he will make certain that everything works right.
We looked over the system. My NIU is out on the side of the house in a metal box and all three CO (trunk lines) come into the house from there. They show up in a equipment closet where the Panasonic KX-TA624 is mounted on the wall - this is the "COX" closet because it has TV, internet modem, alarm system, etc.
It appears they can mount the two DPQ3212s outside in the garage immediately behind the panel and where there are two outlets needed to power the modems. Then they will connect right to the end of the same wires currently going into my NIU - seems they are somewhat paranoid about taking a working system and doing minimal intrusion by connecting at the very same place outside the house as they currently feed. Don't want to place it in the closet where there are plenty of other coax cables to use and power but back at the entry to the house. Sounded fine to me.
It takes two modems because I have three lines but apparently Cox Business has a unit that has four lines per modem so they'll try to get one of those.
Install should happen next week not scheduled yet but I need to identify an option because of the "no going back" feature of this installation.
And by the way...FCC part 68 says that any service provider of services must conform to the standards. Those who make equipment to connect must also adhere and get their equipment certified (it turns out there are 4 ways equipment can harm the network so these are also a part of the standards - "the 4 harms") but if you're a COX and have delegated authority from the phone company to offer phone services, then you have to meet those standards and in one way that's very simple - you have to give the customer one or more CO LINES that are standard and work with their equipment including phones and yes, phone systems. The Panasonic KX TA624 is a registered and certified piece of equipment that is fully compliant with the CO LINE standards. If you're a delegated phone company and you don't give me standard CO LINES that work, you have to fix that. Now I'm not an expert and all I know comes from reading a very painful 440 page Panasonic manual and an even more painful FCC regulations site with 1000+ pages so if I'm misstating something, please be kind but by all means correct me.
So meanwhile the equipment used in the NIU is obsolete and cannot be maintained so COX has to change it and has been trying to do that since 2012. Replacing the NIU so that they can get parts to do that is one driver while putting in a better network is another (the "digital" network) So here comes the DPQ3212 modem which should take the new digital network signals and convert them to the FCC part 68 standard so it can talk to all of your equipment which is also compliant including your phones and your (that's right) Panasonic phone system. It just has to give you a standard CO LINE just like you got before.
Now if your equipment is FCC Part 68 compliant and chances are since it's been operating OK for many years it is, then there is no basis for COX, the delegated phone service company, to hook up something new, take down your phone system, and then tell you it's your equipment. Suddenly we see that we're going to have to put a lot of faith in the DPQ3212.
So now we've laid out the story for the simple home user and next I'll post the outcome of the installation.
