| Digital Voice service over DOCSIS 1.0
I live in Boca Raton Florida, and I have been using Adelphia HSI and then Comcast HSI for a number of years. Recently, I decided to look into signing up for the Comcast Digital Voice service as well. Before I sign up, I wanted to make sure that my/Comcast infrastructure would support the service. My cable modem is a Lynksys model which supports both DOCSIS 1.0 and 1.1. I called Comcast technical support to find out whether Comcast runs the DOCSIS 1.1 on my link, the version required by the VoIP service. I was told that Comcast currently runs only DOCSIS1.0 in my region, but it plans to upgrade my region to the version 3.0 some time this year.
Surprising fact is that Comcast also claims that Digital Voice service is currently available in my region and I can sign up any time. Comcast also claims that PowerBoost and other higher speed option services are also available in my region.
I do not think that Comcast can deliver a good quality Digital Voice service over a DOCSIS 1.0 link and I do not think that it can deliver 'higher-speed' services without deploying DOCSIS 3.0 first. Is Comcast deceiving its customers? |

Is Comcast deceiving its customers? I would say you got a hinky CSR. If a area is offering CDV and "higher speeds" (Were they talking about 16/2 Blast!), it'd have to be at least 1.1 if not 3.0 infrastructure.
Comcast offers 16/2 net and CDV on a 1.1 link. So I think you just got a misinformed rep. And as for CDV, I've got it and it's great, the quality is outstanding. So, I'd say go for it.
PS: Since you're in Florida, you're in the thick of Comcast's Docsis 3 rollout. Enjoy the goodies. |

If you have CDV available and they have powerboost in your area, then they are running at least 1.1. CDV could run on 1.0 anyway with no problem. |

Also don't worry about your modem, they'll replace the Linksys modem with an Arris/Moto/Cisco eMTA. |

I now think that Comcast _is_ deceiving its customers. And it is doing it deliberately. As you can see from a copy of chat I had with Comcast representative, Comcast knows that DigitalVoice and PowerBoost will not work over docsis1.0 link, yet it continues to offer to sell it... Go figure...
Jovelyn(Wed Jul 23 11:08:17 EDT 2008)>I have checked on it and it is docsis 1.0
Jovelyn(Wed Jul 23 11:09:23 EDT 2008)>I am sorry for the conflict.
edin(Wed Jul 23 11:10:17 EDT 2008)>Are you saying that Digital Voice is then not available over my link?
Jovelyn(Wed Jul 23 11:12:39 EDT 2008)>Yes but let me double check on that.
Jovelyn(Wed Jul 23 11:15:48 EDT 2008)>I just have checked on it and the phone service is available in your area. I am for certain with this.
Jovelyn(Wed Jul 23 11:16:25 EDT 2008)>If you like to order now, I can transfer you to our Sales Department for further assistance.
Jovelyn(Wed Jul 23 11:17:21 EDT 2008)>Should you like to check it yourself, you may go to www.comcast.com an enter your complete address.
edin(Wed Jul 23 11:19:43 EDT 2008)>Thank you. We are back to the original question: Digital Voice service cannot be provided over docsis1.0. Which part is not correct?
Jovelyn(Wed Jul 23 11:20:16 EDT 2008)>It can be provided with that docsis.
edin(Wed Jul 23 11:22:45 EDT 2008)>I am sorry, but that is not correct. In order to provide Digital Voice service it is necessary to have QOS support provided by the docsis1.1. Could you please double check that?
Jovelyn(Wed Jul 23 11:23:48 EDT 2008)>Surely. Thanks for that information as well.
Jovelyn(Wed Jul 23 11:24:53 EDT 2008)>Sorry for the misinformation earlier, Edin. Yes, it is not compatible with your docsis. I just have verified on it from our supervisor.
edin(Wed Jul 23 11:27:28 EDT 2008)>thank you. I would like to find out when the service would really be available in my neighborhood. Can you please help with that?
Jovelyn(Wed Jul 23 11:27:45 EDT 2008)>You're welcome.
Jovelyn(Wed Jul 23 11:28:17 EDT 2008)>I have checked on that earlier as well but we don't have the exact time yet as to when will it be available.
Jovelyn(Wed Jul 23 11:29:18 EDT 2008)>However, we will send you email when it is. |

As others have said, I think you just got someone who is not very up on the technical terms and has been misinformed. If CDV is available, your area has to be running Docsis 1.1 since voice service is not possible with 1.0. Even from your chat log, it seems obvious you got a misinformed CSR. |

If you can find the bootfile for you modem you can tell if it is using docsis 1.0 or dossis 1.1 |

Is there some kind of a test app I could run to verify whether QOS requests are being satisfied? Alternatively, would skype work over docsis1.0? |

| Thank you for the information. I checked my cable modem page and here's what I found:
Standard Specification Compliant DOCSIS 1.1
Hardware Version 4.0
Software Version 1.1.5 r2 (befcmu10v2_115r2.ls.p7b)
I do not think, however, that the fact that my modem is docsis1.1 compliant means that docsis1.1 is supported on my link. The Comcast equipment sitting on the other side of the link determines whether docsis1.1 is supported or not. If Comcast representatives are saying that docsis1.1 is not supported on my link, I do not see why I should not believe them. (For example, if I buy and install docsis3.0 compliant modem on my premises, that does not mean that I will have access to all docsis3.0-specific services; I would have access only to those services that are supported by the Comcast equipment sitting on the other side of the link). |

Ok let's make this simple. If your area is CDV ready then it doesn't matter what modem you have because it's gonna be replaced by an EMTA. I would call the local 1-800-comcast to verify if your are indeed CDV ready. I live in WPB and Boca-Delray has had CDV for a while now. Don't rely on chat support to be too helpful.

The fact that the firmware states that the firmware and hardware is DocSIS 1.1 compliant does not reflect in any way what so ever as to what standard is currently in use.

I believe PowerBoost requires DocSIS 1.1 in order to function. So, if you go to speedtest.net and receive a D/L or U/L speed higher than rated for your tier (i.e. you're getting PowerBoost), then you know you're not on a DocSIS 1.0 system. I can't say for sure, but I think the Comcast chat CSR just got confused - just experienced one of those moments myself. If you call the 1-800 number or visit your local office, I believe you will get better information.
I am only a couple miles north of you, I would be very surprised to find that you are running DocSIS 1.0 unless your system was operated by a very small company that was recently acquired by Comcast. |

Sigh....
»en.wikipedia.org/wiki/DOCSIS
This will tell you what actually goes into getting 1.1 ready for cable operators, no rody firmware is not the only part....
If you have powerboost working you are 1.1 complaint, and the reason is 1.1 sets specifies the dynamic throughput ability 1.0 does not have this feature. So off to speedtest.net with you and report back soon.  tell us what your advertised package is, and what you see at speedtest. |
