Re: Moooo
but that 100mbps link is shared with other users in a hub like link to the headend also the cable tv boxes use the same link for there guide data, menus, firmware.
U-verse has a switch like link back to the DSLAM that has a big pipe back to the CO / backbone. |

Austin, TX | Well duh, and those DSLAMs will share whatever trunk ATT has to that office, so you have same problem moved up one step. |

U-verse has a switch like link back to the DSLAM that has a big pipe back to the CO / backbone. U-Verse has the same topography as cable, or it is better said, similar.
U-Verse menus for video suffer from the same latency as satellite I hear (though I wouldn't give up my sat menus for cable). The field terminals with the DSL cards share bandwidth back to the CO. The CO may play a role or not.
The data network is eating the telephone network...it is more important how close to the terminal you are for ip services.
Short of fiber to the home, the telephone distribution system is looking a lot like the cable system.
It's all shared. The question becomes, how far out from the customer premises does the sharing occur? |

Cards?, no cards each customer has an IP address and a dedicated line from remote terminal to home gateway. from remote terminal to CO it's a 1 gigabit line for the shared content |

All internet traffic on Uverse is on Sonet networks. There is no traffic on trunks which are copper facilities for office to office switched traffic. Trunks are dso level circuts and are typically switched circuts. Completely different technology. ATT is offering 10 mb download speeds in our area and uverse voice. The backbone buildup is the biggest push I have seen at ATT. I know this company, they will throw whatever resources at it until they are market dominant. |
