DOCSIS 3.0 & EMTA

Sep 16, 2013 11:29PM PDT

I am going to purchase a replacement modem for use on my Comcast Internet account.

I know I need DOCSIS 3.0. My company has provided me with a Cisco VOiP phone that ties into the company phone system.

Do I need EMTA or will a modem without EMTA do the job? I won't be using Comcast voice.

If I do get an EMTA capable modem, do I connect my phone using an ethernet connection or is there a special connect for EMTA?

It's simpler than you think. You find your cable modem and then call Comcast to ask if they will accept that one on their system.

I have Comcast and decided to purchase my own modem . Comcast wanted me to purchase a specific Netgear Modem that they would accept, what I'm saying is call Comcast first as they already have a list of Modems they'll accept.

So my advice may be slightly out of date.

Thanks to everyone for the updates.

EMTA

With regard to EMTA:

You do not need a modem with EMTA, as the Cisco VoIP phone will plug directly into an Ethernet port and not an EMTA (telephone) port. If you did happen to go with an EMTA modem, it will not interfere with the Cisco phone.

Be sure to check the Comcast website for compatible modems.
