Re: FSAN- Another word for VDSL?
Frank and Dave- I thought you would get a chuckle out of this little article. Or am I wrong? Do either of you think that VDSL will be a next step beyond ADSL, or do you envision a move directly to FTTH? From what I gather, I thought you were both in the FTTH camp as making the most sense. Personally, at this point in time, I can't figure it out? I'm just trying to make investment decisions based mainly on ADSL rollouts.
IF VDSL is going to catch up to HFC, then it better get a move on soon. That's about all I know for now. -MikeM(From Florida)
PS Thread- The line about the cost of VDSL deployment is a little misleading. VDSL will be quite expensive to rollout. Obviously more than ADSL or it would be rolling out today.

VDSL To Play Key Role in Network's Evolution; Special DSL Service Poised to Pave Way for Fiber-to-the-Home
CHICAGO, Jul 6, 2000-- According to a report recently published by the International Engineering Consortium (IEC), carriers seeking to implement the full-service access network (FSAN) over the next five years will turn to very-high-bit-rate DSL service for delivering enhanced, high-bandwidth services to residential, small, and mid-sized businesses. Although VDSL is currently less deployed than asymmetric DSL (ADSL), both technologies will be deployed in increasing number of lines, with VDSL becoming more prevalent by the year 2003.
[Note: This is misleading] One key factor behind VDSL's ascendency is its relative cost. According to the report, Digital Subscriber Line 2000: A Comprehensive Report, the price per one thousand kilobits transmitted over VDSL is almost one-fourth the cost using ADSL. This compares even better with the costs for T-1 lines, ISDN, and cable modems. These economies, together with VDSL's high-bandwith capabilities, makes it the leading technology for transitioning to a fiber-to-the-home architecture.
"ADSL is adequate for Internet access up to 1.5 megabits," says Michael Janowiak, senior director of publications at the IEC, "but the technology is inadequate for Web hosting for small businesses, videoconferencing, video-on-demand, telemedicine, distance learning, telecommuting, and high-definition TV." According to the report, this is why the 20 companies authoring the FSAN specifications will be using VDSL over the next few years, since it offers up to 26M downstream and 3M upstream. Companies in the FSAN group collectively own approximately 50% of the telecommunications copper infrastructure.
In addition to the future of VDSL, Digital Subscriber Line 2000: A Comprehensive Report, covers such issues as DSL market acceleration, deployment status, provisioning challenges, competing technologies, quality of service in DSL networks, DSL in international markets, and more. Thirty-nine industry professionals contributed to the report, which presents an overview of the drivers and directions of the current DSL market. |
