Re: ISDN digest 136
On the "adaptive" DSL:
Think of it as a glorified T1.
It will be a nice addition to the quiver of techniques to deliver last mile
connectivity to the Internet.
All it addresses is the "last mile". It will need a nice, fat high
performance, expensive Internet backbone behind it. It will require a nice
hefty ATM to switched ethernet box at each wiring center. It will need
enough bandwidth and ethernet switched ports to support each DSL line driver
(ie each line to the home).
DSL will be the first new technolog to deliver speeds at or greater than T1
to end user sites in any volume (but not more than a few million max) in the
next 3 years. It will happen before similar volumes of (working) cable modem
systems at similar real speeds to end users.
It will not cost $50/month. The price will be competitive with existing
business Internet services at similar speeds at that time ($500 -
It will not be a consumer service unless it can also cost effectively
(through the content providers, bacbone and to the end user) deliver video
on demand. It probably won't deliver video on demand in that time frame.
