Steve << The only people I know with Cat 5 in their house were my Sister & Bro-In-Law. >> I have a friend building a house in Monterey, CA. I would like to have him install C5 also. Could you please tell me what C% wiring is and who instals it. Is it the phone company? Ratan

[Re: NGN97 News] Steve - I also picked up on the Cat-5 line as being worrisome. This line could be cause for more concern. The pilot network has shown that a carrier's business model can support 200 ADSL lines per DS1 circuit. A DS1 is 1.544 Mbps. If all ADSL lines were active, each user would be limited to about 7.7 kbps! This is an admittedly unlikely scenario, but even with 10% usage, throughput is less than ISDN. Am I missing something here? Rob P.S. Several new home developments in my area offer a "home network" option that includes Cat-5 wiring to every room!

Steve S. Re: [NGN97] The BCR.com address below is the best I can give, the information I posted came from my ATM News Digest subscription. Subscription forms can also be found online. (http:www.atmdigest.com) How about getting together for lunch again sometime soon? Here's the latest: JW@KSC NGN97: NEXT GENERATION LOCAL LOOP TECHNOLOGIES ADSL is past the trial phase and has become a serious business for carriers and their suppliers, according to Leonard Yanoff, Product Manager for Advanced Systems at Alcatel Data Networks. Yanoff said DMT-based ADSL over ATM would prove to be the best solution because of its high bit rates, its flexibility in overcoming varying line conditions and noise, its support for multiple levels of COS/QOS and its scalability. CAP-based ADSL will also be standardized. Yanoff does not expect carriers to use IP over ADSL directly because, he said, such approaches lack efficient aggregation and multiplexing capabilities. At the customer end, Yanoff said a PPP-over-ATM protocol stack would be incorporated into Microsoft Windows 98, or offered by Hayes and other modem vendors early next year. Jay Shuler, senior manager of carrier ATM networks for Nortel, outlined the bandwidth requirements for various WAN applications (Internet browsing, video, telemedicine, teleradiology) as well as the performance characteristics of xDSL solutions. A major constraint in xDSL performance, he said, will be the loop length from the central office to the customer site. Shuler does not expect that IP will be able to provide adequate QoS in the WAN until bandwidth is so plentiful that it's free. John Freeman, director of business development for Paradyne, outlined 3 different DSL network architectures: a centralized routed solution (DSLAMs provide traffic aggregation and IP filtering, with connections to routers via Fast Ethernet or ATM); a switched Vnet solution (DSLAMs have 802.1q intelligence); a pure ATM solution (requires customer ATM interface); a PPP-over-ATM solution (protocol stack required from Microsoft or others).

ATM !News Digest, November 7, 1997 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ NGN97: NEXT GENERATION BROADBAND ACCESS DEVICES It is unrealistic to expect a large segment of the consumer market to move from 28.8 modems to 8Mbps DSL services in the near term, said David Helfrich, VP Marketing/Sales for startup CopperMountain. Helfrich expects that only 1% or 2% of the 100 million phone lines in the US will be upgraded to a multimegabit service by 2000, due to a variety of pricing, technical and deployment constraints. He believes the "sweet spot" in the DSL market will be in providing a business access solution between ISDN and T1 speeds. A more bullish view was presented by Jerry Parrick, CEO of startup Diamond Lane, who described the "land rush" currently underway for the limited resources available in the deregulated central offices. Parrick asserted that xDSL represents the best chance for incumbent carriers to stop the coming "PSTN implosion," while for new competitive local exchange carriers it is the best chance to get in the door with a multiservice offering. He believes xDSL will be the killer ATM application. Rob Newman, CEO of startup ATMosphere Networks, said that all of the last mile access technologies would require carriers to build out capacity in their metropolitan networks. His company is developing fiber access rings that use a "thin layer of ATM" to provide much better multiplexing than current add/drop SONET solutions. ATM !News Digest, November 7, 1997
