Certified Cable Modems
I am researching DOCSIS 3.0 cable modems that utilize eMTA (telephony) so I do not have to have a separate device for my Cox Telephone Service.
Aside from the Cisco DPQ3212 cable modem, which is Cox certified, I am wondering if there are additional cable modems that Cox will allow to be used, or if other Cox customers are currently using for their Internet/Voice services at home.
I have found the following other modems that are not on the Cox "certified cable modem" list, but are DOCSIS 3.0 and do provide eMTA / telephony function that may be used for the Cox Voice Service:
Arris TG1672G (listed as a "Gateway." What's the difference between a cable modem and a gateway? The data is digital anyway, right? No need to demodulate it to an analog signal anymore).
Can anyone confirm if there are additional cable modems or gateways that are not "officially" on the Cox Certified Cable Modem list but are using them without issues? Is anyone using the above modems in their home?
