Begging your patience....I'm a technical person, but new to DSL and have questions.
My parents are in the process of getting aDSL from Earthlink, their phone company is BellSouth. They live in an older neighborhood, approx40 years old, with lines about ground on poles. It is approx 6-8k ft to the CO.
I have read about and think I understand the two typical configurations1) splitter on side of house or 2) splitter inside at the appropriate phone jack and filters on all other phones. They are supposedly getting the latter....a home install kit with DSL modem and line filters to install on all the other phones.
The Earthlink rep said BellSouth would provision the line, then notify earthlink to ship the cable modem equipment to my parents, then they would plug in the filter first, then the DSL modem.
I was concerned about getting the DSL before the filters were installed, but the earthlink rep said the DSL signal didn't really start until the DSL modem was plugged in, so it wasn't a problem. He also said no one would typically come to the house for any work, it is usually done remotely.
Questions / concerns:1) Is it true that even though the line is "provisioned", that the DSL doesn't really start until the DSL modem is plugged for the first time? Does the modem request a sync and that turns on the high freq DSL signal the first time? That would alleviate my concern about not having the filters plugged in when the line is "provisioned".
2) How often can the phone company successfully setup everything from the central office, without making a trip to the house? I have read about the possibility of loading coils that are typically every 3k feet on older circuits. I also thought that they have to come to the house to test the circuit.3) I am concerned about using the filters (vs splitter on side of house) configuration in an older house. I know their phone wiring is not as clean as the newer home installs. What kind of success have folks seen using the filters in 40 year old home installations?
