said by Joe12345678  :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. 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? |
