Arris TM722G the only modem I can use for triple play?I just signed up for Triple Play with Comcast and they told me that I can buy the Arris TM722G modem at Best Buy to avoid the $7/month rental fee.
Is this the only modem I can buy or are there other models that will work as well? For example, can I use the Motorola SB6120 or Zoom 5341? |

That the only one that you can buy right now and only at Bestbuy. It cost's $149.99. They could be charge to install it also. |

To clarify, it has to be an EMTA, as your phone service comes from the device as well. |

Not at all, tell them you want a d3 modem for internet.
I just had my emta internet portion turned off and they sent a d3 modem to use instead. |

If you had your " internet portion turned off", what did they send you for voice that would be better than the TM722G. |

And just why is the dpc3000 better than the TM722G. As far as I know, unless there is a new model, the dpc3000 is not an EMTA, so it won't work for voice. Both are Docsis3 and the TM722G has a good track record with Comcast. It is also the only EMTA available for retail purchase. Also remember, whether it is puchased or leased, it has to be installed by Comcast. There is no self-install option with voice. |

@ Master Wolfe. In some areas a straight modem and an eMTA can be used in tandem with each other via a splitter if the signals are adequate so it really depends on ones particular market area as to whether or not they will allow this setup. |

Indeed, that is how I'm setup. I was simply trying to clarify for Grayson73 , but may have caused more confusion, LOL. |

There could be another reason that a separate cable modem and eMTA are needed - the location of the telco entry point. An eMTA is a great deal pickier about such a location than a cable modem for that reason (the eMTA normally covers all the phone jacks in a residence or small business). I'm not talking out of my hat - we're triple-play (upgrade from double-play) customers that added CDV; however, the telco entry point location forced use of a separate eMTA (our customer-owned cable modem is in the basement, which is also homebase to the household LAN) in the garage (the Arris TM422). I have (rather my mom does) one major problem with the eMTA - it does not work with virtualized second lines (we had one specifically used by our plain-paper fax machine). Other than that, the rest of the service is at least as good (in the case of the base CallerID support specifically, far better) than it was with VZ copper POTS. However, the virtual-line/fax issue may well chase us back to VZ, at least for phone (and to FIOS, as VZ normally doesn't do copper, even for phone-only service in Maryland's FIOS-available areas). |

location of a telco NID has no bearing on 99% of residential installs...a simple backfeed on a second pair is all thats needed....
also most fax machines dont play well with digital phone...whether it be cdv, vonage, etc.....however some issues come from either; having the baud rate set too high, the voicemail indicator on the line; or by not running a single pair into the fax machine.... |

Let's remember the OP"s original post:
Arris TM722G the only modem I can use for triple play? I just signed up for Triple Play with Comcast and they told me that I can buy the Arris TM722G modem at Best Buy to avoid the $7/month rental fee.

He was not looking to use two modems, only asking if there was an alternative one to purchase. No real need here to get into the pros and cons of using two modems- that would be another thread.
The answer to his original question is still "no" |

True on fax machines not playing nice with eMTAs - however, in this case, it's not really the eMTA's fault. One of the slicker tricks that the leading RBOCs, and some CLECs and ILECs that were never RBOCs (Verizon among the first, CavTel among the second, and Frontier among the last) have done is the Virtual Second Line (sometimes called Distinctive Ring) - and it acts like what it sounds; a second line run in parallel with a primary line, but for use with specific devices (such as fax machines, and some alarm systems). It requires support by the subscriber's central office; however, that is pretty standard fare among switchgear usually deployed by RBOCs, CLECs, and even the smallest non-RBOC ILECs. This is not supported by any eMTA, though (while there are multiline eMTAs, they are the traditional sort, and don't support the virtualization of that second line). Alarm systems can be worked around; however, fax machines generally can't. |

Thanks, everyone. Was just wondering if there was a cheaper option than the $149.99 Arris TM722G, but I guess not!
Since rental is $7/month, it will take 22 months just to break even. I wonder if it's worth purchasing. |

Probably not since they have to install it anyway.
Who knows what may be available, or what changes may take place within the next 22 months.
My feeling is that it is best to have them responsible at this point. |

Thats not true in all areas. We have self install triple play now here in CT. I don't know if we are a trial market or what but ive already been to TC's on these. "Make drop hot" sro's have been going out for almost a month now. |

The Comcast guy just installed the modem and it's a TM504G. Is this better or worse than the TM722G? |

Should I switch to the TM722g? How do I check what tier I'm in? |

cralt, do you know which bestbuys carry the Arris in CT. Or are you referring to ordering triple play packages? When I was previewing the packages online and adding them to my cart, I was never offered a selfinstall option. It gave me a calendar to pick an install date for. I haven't ordered yet. |

Comcast makes no assurances that alarms, fax, etc will work with their service. And just because you test your alarm today and it works, doesn't mean it will without a doubt work in the future. If you need to use an alarm, fax, geriatric monitor, etc I suggest you use a service that guarantees compatibility. |
