Hi Folks,I currently have a copper based phone line (Verizon) and want to move to Cox’s voice (phone) service (I currently use Cox for TV and Internet). My house was built in the early 1990s and is wired with basic analog wiring common at that time, with several phone jacks spread out throughout the house.I went to a Cox store and spoke with a rep and got info that seems odd. So, I’m looking for some clarifications regarding Cox Voice installation and features...1) I have my own internet modem and router and want the voice equipment to be separate. I was told that I could have a separate modem for voice and that they would issue an Arris TM3402 for that. I want to make sure that particular model can be activated for voice only (essentially eMTA only).2) With a separate phone (voice) modem, is there a restriction on placement other than access to power and a cable outlet (does it need to be connected to the internet modem for example)? 3) I was told that I could not connect the voice modem to my home phone wiring by plugging the TEL port on the voice modem into one of my phone jacks. I was told that the TEL port on the voice modem must be plugged directly into a phone and that I would need to rewire my house for digital phone service if I want to use multiple jacks throughout my house. This makes little sense to me since a phone is an analog device and so is the analog phone wiring that is in my house. Can I connect the voice modem to one of my home’s phone jacks to enable the Cox phone service to be accessed on other phone jacks?4) Can I change the number of rings that occur before VoiceMail picks up a call ?5) Can Call Waiting be disabled and if it is disabled do callers get a busy signal or get sent directly to voice mail?Thanks a bunch for any help!Dean
All houses have basic analog telephone wiring. It's what the modem does: converts a digital signal to analog. If your rep was correct (not) we'd all need digital telephones. Not digital features...but new telephones capable to receive digital signals.
Mouth is correct. Cox can provision the modem for Voice only. You'd probably need a 3-way splitter. Primary > Cable Box, DOCSIS, eMTA.
You can configure VoiceMail and Call Waiting online (Cox.com).
When I bought the house 12 years ago I had Verizon run new copper lines to the house and that has been my phone service ever since. I have a grey plastic box on the outside of the house labelled "Telephone Network Interface", which I am assuming is the demarc (it has a plug+jack that appears to connect the house wiring to Verizon's service). What gets changed to make it work with packet-switching?
I read about the battery backup of the TM3402 requiring the phone be directly connected to the voice modem (it must go into some "low power" mode when running off battery). I asked the rep if I could just run the 3402 off a regular UPS (a computer sized UPS should power the modem for quite a while) but he said that would not work. That does not seem right.
I don't know what wires get changed. I live in a townhouse community and he was too fast removing and reinstalling wires for me to observe...and it was just a thicket of phone wires.
The manufacturer probably did design the eMTA to not work off a UPS. Manufacturers love to sell the proprietary batteries.

That might explain it.

Running the modem of a UPS shouldn't be a problem. It may not have the low power mode (because it can't detect power loss) but it should work fine enough.
PS. Here is some more info on the battery backup.
Thanks for the link. Very interesting. The modem does sound like it goes into a low-power voice-only mode when power is cut.
