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?
I HAVE AN ADDITONAL QUESTION AFTER READING HUNDREDS OF POSTS AND GUIDES IT APPEARS THAT THE PHONE JACKS ON THE BACK OF THE DPQ3212 ARE REGULAR PHONE JACK CONNECTIONS. THEY'RE ALWAYS DESCRIBED AS CONNECTING TO EXISTING PHONE CABLES IN THE HOUSE OR DIRECTLY TO A PHONE.
NOW I DON'T KNOW FOR CERTAIN BUT IT OCCURS TO ME THAT THE 3 LINES I HAVE CURRENTLY COMING IN FROM OUTSIDE THE HOUSE WHERE THE CURRENT MODEM IS LOCATED IN A UTILITY CLOSET, PLUGS DIRECTLY INTO MY PHONE SYSTEM (PANASONIC) AND THOSE MUST ALSO BE STANDARD PHONE LINES BECAUSE THEY COULD JUST AS WELL BYPASS MY PHONE SYSTEM AND GO DIRECTLY TO ONE OR MORE PHONES RIGHT?
SO IF THAT'S TRUE, THEN IT WOULD APPEAR THAT IF I GET TWO DPQs I WOULD HAVE MY THREE LINES COMING IN AND COULD PLUG THE PHONE JACKS ON THE BACK DIRECTLY INTO MY PHONE SYSTEM TRUNK LINES SAME AS CURRENT AND EVERYTHING SHOULD WORK THE SAME?
ANYONE KNOW IF THAT'S TRUE?
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.
WOw, you totally lost me there. Are you saying Cox is required to provide phone modems with 4 phone ports? Don't you think that is a big waste of money consider how few people have more then 1 line?
Also, Cox's next move is into virtual phone via app, so what physical lines you have won't matter as much in the future. TBO, if it was me, I would pay for 1 phone line, use the DPQ3212 for internet and phone, connect a router and Google Voice adapter. Not only would this give you 3 physical lines, but greater flexibility. If you need to move your office, you can just move one of the google Voice adapters instead of having to change your Panasonic.
What I am saying is that your phone services provider (in this case COX) is required to provide phone connections that comply with FCC p68. Those CO LINES are standard and should plug and play with any equipment - phones or switches/PBX/KSU that is registered and certified by FCC p68. (like the Panasonic KX TA624. And all of the modems they install whether one or two are paid by them not me. They must take their digital network and convert it to something I can use - ie. the standard CO LINES.
I appreciate the suggestion of the Google Voice Adapter. I'm trying to read and understand what that is. It seems that I'm not as technical about available solutions - never had to worry about this stuff and don't have the background for it. But having two installers come out and tell me the DPQ3212s won't work with my Panasonic made me step back a little. I'm having to play catchup because understanding this stuff is not my field and internet searching takes time for education purposes.
It appears you're saying the two lines that come out of the Google Voice Adapter are the same as CO Lines and I can plug them into my KSU. So that means I have a VOIP service provider working via my internet connection that's now giving me phone service - I would need two boxes to get three lines - and then I just need to shut down COX phone services which means I loose voicemail from Cox along with integration into my TV system and just pick that up from the VOIP provider.
I do have an alarm system connected to one of my phone lines out at the NIU so I would have to get that connected somewhere else.
Ok, so you were only saying Cox has to make it so people don't have to buy special phones or anything to use their service. My point is no where in there does it say a ISP has to provider a certain number of lines.

That might be tricky. Do you have any phone lines running out that way that you could connect to your Panasonic?
I think what is causing the main problem is Residental Installers don't have experiance with mini PBX's like your. They assume it's a digital PBX that uses ethernet and digital phone lines, which it is not. However I think that is what is causing the knee jerk reaction. If you just ask them to install 3 phone lines into one room, they should be able to do it no sweat.
No other phones lines but once they put in the two modems next week the alarm connection should still be active because they're going to feed the modems right into the box outside the house where the old NIU dropped out the three lines. So unless the alarm system can't handle something about the new lines, I should be OK (I've read a few posts where old alarm system has a problem) So we'll see.
I'm sure that you're right. The COX guy alluded to that as well. He has installed several houses with Panasonics and no problem so he said the installer (they are outside contractors by the way) were just trying to avoid the unknown and had no experience with it. Of course you can see why they would be leery - if the phone system doesn't work when you convert, you can't go back. You're dead and the only thing you have left is to point the finger at Panasonic.

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?
The RJ-31 is typically in the alarm panel.
The demarc is just a demarcation point where the handoff of a circuit physically happens, essentially a provider says "we are obligated to only go this far". In the business worl it typically has been an RJ-21 block, a 50 pair 66 block, telco comes in on the left side, ckt is 'bridge clipped' to the right side, and the customer takes it from there. The NIU does the same thing, just looks different.
Sounds like you'll be ok as you've described it, Michael. By the way, what state are you in? I'm in Phoenix.
HI Michael, As promised, I'll follow you here while I wait for any response from a Cox network weenie. The FCC part 68 analogy discussed here is sufficient for describing the need for compatibility between different pieces of equipment connected together, though it mostly addresses electrical safety, and "do not harm the Network" B.S. It does also address that each piece of equipment connected to a carrier's network that IS "FCC PART68,, TYPE ACCEPTED" meets certain requirements. What you and I hope is the scope of those requirements includes performance between your switch and Cox's 3212 derived dialtone from the back of the E-mTAs. If Panasonic says that a nominal loop start dialtone line should work with their switch, then Cox, in my opinion is obligated to provide industry standard 'dialtone' as specified in the Bellcore GRs. Besides PT68, the GRs define all the esoteric things like response to switch-hook flash intervals, DTMF freq stability, leakage across T-R when on hook, before going off hook, and the list goes on and on. What's important for you is "why Shouldn't it work", and Why Won't COX comply with the GRs, or failing that "What's my work-around"?
Like you, I'm still learning where to ask Cox People these questions, and so far I'm still asking. You can see what I'm up against in my separate inquirey regarding my 3212 and the way it is mis-behaving with my old Uniden DECT2080 wireless phones.
