I am planning to upgrade to Gigablast internet, which means I'd need to upgrade from my DPQ3212 modem to one with DOCSIS 3.1. However, I have a phone line and it is my understanding that if I am to buy my own modem, I'd still have to use the one provided by Cox for phone service, meaning I'd need 2 separate modems, one for internet and one for telephone service. If this is correct, and I follow through with getting Gigablast and a DOCSIS 3.1 modem, what exactly would I need to do to set it up when it arrives? Would someone need to come to our house to set it up (are they even doing house visit right now?), would I need a coax cable splitter or could I use a different coax outlet in the house? I've looked into this quite a bit as gaming on my current plan has been quite frustrating, but I'm a bit confused about the details so any help is appreciated!
Can't you upgrade to the D3.1 eMTA Arris TM3402? That will get you phone and Gigablast internet, just not router/wifi. Also, you wouldn't have to worry about splitting the coaxial for the two modems.
not sure if this is the proper place to pose this question. You guys recommended the TM3402. Anyone know how/where to buy one ? i have searched just about everywhere i could think of with no luck. Please advise.
This type of modem is not purchasable as it is provided to customers that have phone with Cox (but would still need to be returned if services were ever shut off). If you are a current phone customer, we would issue you this modem if you upgrade to gigablast and do not need/want a modem with built-in wifi.

well, that explains why i cannot find it thanks. But it doesn't explain then why it is on Cox's list of compatible modems you can purchase to replace your rental modem.
The Compatibility list is not a list of purchasable modems but a list of compatible modems. For a modem to work on CoxNet, Cox would need to configure (provision) the modem and these modems support the configuration of Cox.
After you choose a modem from the list, you can purchase from a retailer. However, if the modem supports Cox Voice...and you want Cox Voice...Cox can only issue/rent the modem.
The Cox Voice limitation is because only Cox can configure a telephone modem to work on their telephony systems. You can still purchase your own Internet modem from a retailer but if you also want a telephone modem, only Cox can issue the telephone modem.
