Re: How is this service is not hindered by distance
said by djtim21  :Isn't regular telephone (pots) hindered by distance? don't you have to have load coils and bridge taps in order to send pots farther with out an RT "amplifying" the signal? Maybe we can get some guru's from the bell forums in here to explain that. Distance limitation of DSL is due to non-line powered systems.
The technology COVAD is planing to use is a powered-line technology that will use the electrical properties of copper with the use of repeaters. This is how they can overcome distance.
The system COVAD plans to use takes services from the local access platform, combines multiple services, adds voltage to power the line and sends the combination out of their facilities in a digital format.
At longer wire distances, the repeaters will recover this digital format and recreate a "clean" digital signal for longer distance transmission.
I would like to see what they plan on doing when they try to add this to a copper pair that has current analog service. COVAD does not own their own copper. |
