Be sure to ask Comcast to check compatibility on any model.
I have just signed up for Comcast Triple Play to be installed next week. They charge $7/mo. for cable/telephony modem. Comcast rep. told me that to avoid the monthly charge I can buy an EMTA device (cable and telephony combined?). I looked at compatible modems on their website (http://mydeviceinfo.comcast.net/) but some say cable modem some say telephony modem some say cable modem w/ embedded MTA and I am confused. I don't want to spend an arm and a leg on a modem and am not interested in wireless. I just need DOCSIS 2.0 or above and something that handles both my internet and phone. Any help appreciated.
