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.
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.
Michael2062 said: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?
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.
Tech Characteristics for Cox Dialtone
I can't really comment on all the technical detail in your post. What I think I know is how Cox works and how I eventually got their attention to prevent all the bad things I had heard about from installers and people online with problems. I got a tech out to look at my setup and then him speak to his supervisor onsite about the potential problems of the installation with my Panasonic. His supervisor selected an expert who had installed a lot of upgrades and some with Panasonics. This was someone who knew the technical details of why most installations with switches failed. But after talking to them I would say that's where they stop - they operate at the PT68 level and I really doubt that their field forces know the detail you're talking about or could be helpful in troubleshooting an issue with your Uniden. It takes a lot of work to get their best resources but your issue in my view is a design and engineering issue like this: (1) Does the Uniden really and actually comply with everything PT68? Does it really comply with any other standards? (2) have the modems you have been connected correctly? (3) Do they have a good ground connection and does the Uniden have a good ground connection? (I believe the CO pairs are send and receive that rely on a ground to stabilize their signal, so anything not right about grounding and the system becomes unstable on signaling). (4) do the new modems have a marginal RF signal? Cox can measure that from anywhere and of course if RF signal is low, then funny things start to happen.
I just don't see Cox helping with this very much - having installed thousands of modems and a variety of equipment that works, and having no choice about installing the new modems, they just don't have any choice but to shine on the outliers.
Hi Michael, I suspect you're right, as far as how hard Cox will work to fix. I'm glad you were able to get the right resources to get you up and running trouble free. I may have to replace the Uniden's. No great loss if I do. For the time being I'm committed to getting my setup to 'play' with Cox's stuff, and see how it works. The bigger issue is the totally weird behavior with several different IVR's around the Country.
