No, the "problem" and the advantage is that ADSL is done over cheap copper lines, not deer fiber optics. Due to the high frequencies used, the capacity and quality of the line severely hampers speed. My brother has his corporate Intranet over ADSL rather than ISDN ADSL gives him maximum 12x64K = 768K over a leased line. It must be a leased line as the others have band pass filters and are not capable of transmitting the high frequencies needed for 768K or as AVCO states 9M. You can very loosely compare it with a coax cable which might not exceed a certain length either... C. AVCO thread count and impotance (1900%) rises like AVCO stock price, irrational exuberant.

Coffee Pot says, sounds sort of cheesy Actually he said: For the modem speed to be dependent on wire length from carrier to receiver sounds sort of cheesy .... That's the way most of this DSL (Digital Subscriber Loop) technology works. It takes advantage of the direct link between the customer and the central switch. My limited understanding is bandwidth drops by a big factor when the signal goes through an analog line amplifier, because those amplifiers were designed for voice frequencies and reject the higher frequencies needed to transmit data at higher rates, The line amplifiers are also noisy, and can introduce noise into the signal. Thus, the way around the problem is to avoid the line amplifiers required at greater distances. I went over to Avtel's homepage at avtel.com and didn't see anything about a new sort of modem that they've developed. They say they're a service company, so my first guess is they're just installing someone else's ADSL modem. No matter, ADSL is a standard, and it doesn't seem they've improved on it; they're simply offering this service in the Santa Barbara area.
