axel--I can't swear how every telco operates, but the industry standard, at least the last I heard, is going to a 12kft loop. This will eliminate the need for load coils. Sure, there will be senarios where the loaded loop will still be needed, ie loops longet than 18kft, but as far as DSL is concerned, the pair has to be unloaded. This is because a digital signal is too high in frequency to pass through a load coil. DSL is a digital signal. It will work out to about 18kft on a non-loaded cable pair but much past that and the signal degrades very rapidly. You're right about the bridgetap, they need to be removed. DSL will not tolerate bridgetap. The DSL will work with some bridgetap, but not well. We've just gotten into the habit of removing them, if they exist, when we test for a DSL service install. As far as the customer being within the measured distance but the cable taking a rounabout path, that can be true. I will take an electrical measurement at the customer premise. If they fall within the 18kft limit then I will test their line for analog service, then do a wideband test. If they pass the wideband, they get hooked up for DSL, if not, the cable pair gets analyzed to determine the problem and repaired. If the analog test is good, the wideband test will "usually" pass. You sound like a phone guy and probably have seen Outside Plant magazine. Don mcCarty has some very interesting articles about digital, as well as analog, communications in this magazine. If you don't have access to the magazine, they are online and he shares his knowledge rather freely. www.ospmag.com. He has a monthly column in the magazine.
