Sorry for the SPAM! I didn't mean to have that message posted here. It should have been posted on the ATON board. I am watching AWRE as well. Sorry, and best of luck on your trades. FT

Hi Scrapps, some bad news for g.lite: eet.com $10 microfilters pose threat to G.Lite By Will Wade and Loring Wirbel EE Times (11/12/99, 3:47 p.m. EDT) DALLAS — An inexpensive passive component could swing open the door to full-rate asymmetric digital subscriber line connections and allow carriers and users to bypass a slower ADSL version for which many companies only recently have marshaled silicon support. The $10 microfilter in question could shake up the market for G.Lite, a 1.5-Mbit/second version of ADSL that can be installed in homes without requiring an external splitter to separate voice and data traffic. Full-rate ADSL pumps data through the same copper telephone cable as voice signals at rates up to 8 Mbits/s but requires a splitter, which must be installed by the user's local phone company. G.Lite removes external splitters from homes by using a discrete-multitone (DMT) subset, reducing the maximum downstream capacity of ADSL. But after the first G.Lite chips hit the market, tests by a team led by John Cioffi at Stanford University revealed that the splitterless systems could see severely eroded data speeds when nearby phones were taken off the hook, and users heard significant noise when trying to place a voice call. As a tactical response, Texas Instruments Inc. and Globespan Inc. designed microfilters — tiny devices that plug into every phone or fax in the home to demarcate voice and data traffic and keep the signals clean — to sell along with their chip sets. 2Wire Inc. (Milpitas, Calif.), whose main business is residential gateways for broadband consumers, developed its own microfilters to drive the total market for its core business, and it has outsourced production to passives manufacturers. Ironically, the solution intended to fix G.Lite from a technical perspective has harmed it on the marketing front, since microfilters may now be used with full-rate modems to eliminate the external splitter. "The implications are simple: You can have the same reductions in truck rolls you get with G.Lite, and speeds up to 6 Mbits," said one source at SBC Communications Inc. "You do the math." Call it G.Dumb? While there are still valid reasons to use G.Lite technology in carriers' central offices, it seems likely that the filters will shake up the market for home DSL systems. "We say G.Lite should be called G.Dumb," said Ted Faganson, director of product marketing for 2Wire, which started shipping microfilters this month for $9.95. They plug into standard RJ-11 wall jacks. "Using microfilters means there is no purpose in deploying G.Lite to homes," he said. "If the line can handle the full 8-Mbit/s speeds and the modems can handle either speed, why not use regular ADSL?" .... ***** All the best, Michael
