| Broadband phone without the broadband? I guess they are just assuming the whole lack of broadband deployment is going to magically fix itself in time for people who currently survive on 33.6 dial up to use VoIP?

This will BECOME part of broadband deployment. Everyone that gets POTS service will also get with it a minimum quality DSL broadband connection (likely 1000/384). Your POTS will share this connection. The BIG advantage of this is that no longer will telcos have to provide one copper pair for each POTS line back to the phone office. They will be able to run many POTS lines on one pair. They will also be able to use the extra pairs for pair bonding to increase distance and/or speeds of DSL. Finally, they will be able to use products like Adrenaline (google it) to also improve speeds and/or distances. |

The minimum should be 100/100 mbps.

Charlotte, NC | They have been running 96 lines on 4 copper pairs since the mid 80s. Much of BellSouth network was on fiber or copper carrier systems unless you were close to the central office. The rural areas are all digital to a node. It support POTS and can support slow DSL by adding more T1 lines. Not good for streaming but worked when the internet was e-mail and web pages.
At&T is already moving to all IP but they are not forcing people off POTS. |

At&T is already moving to all IP but they are not forcing people off POTS. What you say is true. I used to have POTS with Pairgain. Maximum modem speed is 33.6 with Pairgain.
The telcos have used 'mini Parigains' (DAMLs) for years that can multiplex a virtual POTS line onto a physical one. These use DSL, and are powered from the C.O.with 140 volts.
But in the cities, each POTS line does have a pair back to the C.O.
Eventually, most people will probably get POTS in a way not unlike U-Verse works-fiber to the neighborhood and copper to the home. |

Yeah we would all love that but companies in this country are to greedy to offer that at a good price

Minor clarification-- up until recently 96 lines ran on 8 pairs. It was 4 T1s but they were each 4 wire circuits. Also digital slc carrier systems go back much further than mid '80s-- the first to be deployed in the field was in 1964 in Illinois. |

Finally, they will be able to use products like Adrenaline (google it) to also improve speeds and/or distances. That would be the end of voice service for rural areas. Telco will over subscribe the 1 T1 SHDSL line pair with 50 customers and their IP and VOIP traffic. Currently state PUC regulations don't let them put 1000 customers on a DLC with a T1 back to the CO. |

Yep put 140 volts over a line. That works unless the main reason you are using them is so you do not have to fix the plant. So put 140 volts over bad copper and what do you get????? Been there, seen that. |

said by Gbcue:That minimum is too low. The minimum should be 100/100 mbps. Agreed that 384 Kbps is too low, even 512 Kbps may be too low unless it 100% guaranteed with low latency 24/7. "Best effort" 756 Kbps low latency service (forget about any high latency service such as satellite) should be fast enough for VoIP. |

said by Sammer:Agreed that 384 Kbps is too low, even 512 Kbps may be too low ... But I am loathe to pay more than $30, maybe $35 a month for 1 Mb/s, or even 768 kb/s upload. So far, the 512 kb/s upload I have has not hindered me in the least. The main reason I haven't dropped back to 1.5 Mbps/.384 Mbps is inertia. I could be putting $60 a year into manga and anime, otherwise.
