I don't think so? My friend has phone service and it is entirely different.

It should, it works with Comcast and I think the technology is the same. Connect it to any phone jack on phone side of the cable modem. Only downfall we found on our Comcast setup is the caller ID stops working, but well worth the benefit. Not one telemarketer has made our phone ring since we got this.

I don't know understand your question. I used this for Comcast cable here in Maryland until my service started having problems. Not sure if it was this modem or something with Comcast signals. But I've since purchased another modem and Comcast works fine. Hope this response helps

This is a designed for cable. Most likely comcast is powered by telephone lines. If true you need a telephone jack connection.

No, it is just a cable modem for internet only. It's not for a broadband phone line or a router to connect other computers too. You would need a router to have more devices hooked to it and have wireless capability. It does work well with Comcast internet only tho.

The modem will for internet but it won't work for phone service. You must buy through comcast for that to work. I did not realize this when I bought it. If you need for phone service suggest you return and buy for comcast

I cannot tell you if it will work for you. I do know that you cannot attach your phone to it. Contact Comcast and ask before buying it.

I use it with my ISP. The telephone works like a geem. Make sure you have a switch with POE. If not, get a power injector for the telephone. I use a EnGenius EPE-5818af device. If you have the proper information, and Comcast provides the proper info for the 504G, it should work just fine. Look on the Comcast web site to see if they list the programming options. If not, call tech support before purchasing.

Sorry, but I don't know if this will work with the Comcast digital service.

Hello vyk_2000, I can't say definitely say it will but if Comcast is using a VOIP system (Voice Over Internet Protocol), as I suspect that they are, then yes it should work. It is a very easy system to program the blocking of telephone numbers. I have put one on a FIOS system and it is on the analog side so the call is intercepted before reaching the telephone in almost all cases. It might ring a few times but you never receive the call at the telephone unless you pick up the telephone while it is ringing.

No you need the modem that Comcast provides, it's a lot bigger with a different config. This one quit after a couple of months use and they would not refund my money just offered another junk one like it.

You should double check with Comcast to ensure that you can use this product with your specific plan, but in general, yes! -- this router is designed to replace an existing cable modem or cable modem/router combination.

not too likely, the phone jack on the comcast circuit is an analog line; which converts to SIP;if your using for modem communication (likely) there'll be issues with compression and latency.You can try it... but no bets on my part. I work for a company that installs AT&T;'s flex circuits. Faxes will work with the G711 codec applied. but modems simply dont.

If Comcast uses cable signal (with a coax connection), then no. This is for DSL; so it needs a landline-type connection - though you don't usually need a landline account. We used it with AT&T dsl. And yes, it is a modem and router all in one. Takes in the signal and pushes it out too. :-)

Yes! This is Comcast's newest modem and is designed specifically to work with their service.

this is NOT a cable compatible modem. This modem is for DSL connection use only. You need to continue to search for a Cable Compatible modem... it should have a spot in the back for you to screw in your com cast cable line. Possibly refer to Comcast customer support for an updated list of compatible modems. I'd hate to spend the money and it doesn't do what you need.

The does not have a coax input. So, if Comcast uses cable connections (rather than phone line hookups), I don't think this will work. I used it with AT&T; DSL, because they provide their signal (in the house) via phone lines and/or ethernet cables. Hope that helps. :)
