Is Comcast DP (non-IP) line powered?
I think non-VOIP cable telelphone is superior to Cable Co VOIP since Cable Co VOIP could be affected by overloaded nodes and is over a packet best effort network rather than a circuit switched network. I know Cable Co VOIP has priority over internet traffic (QOS) on the internet channel. |

Not CDV, Comcast Digital Phone service.
Had it here since it was AT&T Digital and it has never failed to work!
YMMV.

Acts just like a "normal" telephone, but there is no POTS line. All coax.

the new Digital Phone service is actually not touching the Internet of the Comcast network. It is on its own equipment and over loaded nodes have nothing to do with it. Its all itself. once it hits the Node it travels back on the fiber line and then to the Phone network.
Never touches the Internet whats so ever. So the Over loaded nodes are not an issue. They put the network out to be ready for this; plus a simply split of the node would create more room for Internet customers and most tiers without a problem.
Plus what is the chance everyone one a given node will be using the phone or Internet at once? enough to bring it to a halt? I don't think so. |

Eh, SOME systems that use the RSU device, Digital Telephone, are actually house powered. While many systems are 90v powered, some do actually use house power.
Apartments, however, where an internet RiSU is used, it's most definetly house powered by the wall with an average of 8 hour back up.
I still ahve 5 lines of DTS with unlimited long distance (Any Distance Package) and do not plan on giving that service up anytime soon.

Re: CDP is great!
I'm assuming that's the old circuit switched implementation.
Basically a dedicated phone line over coax, with a NID on the house that you connect to the existing telephone wiring.
It was incredibly expensive to deploy, but very reliable and superior to the VoIP alternatives available at the time.
ATT installed the phone service at my house more than a year before their cable modem service became available. |

| I wonder if we'll be able to get that?
We're going to Comcast (actually, they became our operator as of August 1st) here in Mendocino County soon, we're an Adelphia market, and will be part of Comcast's Bay Area network. I wonder if we'll be able to get this? I don't want VOIP, too unreliable, I like this because it sounds like it would be hardened and reliable like regular phone service.
