...I'd be very surprised if we don't retest the recent lows. Me too. My traps are set and ready to be sprung.

LanTimes article on DSL This paragraph or few bugs me: But for all of xDSL's appeal, network and IS managers would do well to approach this new technology carefully, because deployment raises a number of issues. One of them--the state of the local loop--is proving to be less of a problem than many observers had anticipated. But that will be little consolation if you launch an installation effort only to discover that the copper wiring into your facility won't support it. That unpleasant surprise can happen. "In reality, you never know if ADSL will work until you install it," says Rob Brading, marketing director at Atlantech Technologies Ltd., an xDSL management-systems vendor based in Cumbernauld, Scotland, and Westborough, Mass. "There is really no way of testing it; the best piece of test equipment is actually the ADSL equipment itself." The line must be unloaded, without any load coils or bridge taps. Gauge mismatches--24 gauge in the feeder and 26 gauge in the main trunk, for example--can cause discontinuities and reflection, slowing throughput. The key variable, though, is the length of the loop. Copper in perfect condition will support 1.5Mbps ADSL over distances of up to 18,000 feet and HDSL over 12,000 feet. But few installed copper loops are in perfect condition, and in some cases the telco records may be in worse shape than the copper. uworld.com Derek
