Today there was an article in the sci-tech section of cnn.com mentioning
that Microsoft was teaming up with Intel and Compaq to offer xDSL
to the homes for a very low price.  They claim to be able to provide
Internet access "30 times faster" than regular modems.

The announcement also said that four of the five baby Bells (all but
BA) are also in on the deal so they'll all use common xDSL standards,
something that's been a problem in the past.

But the important thing they did not say (and which may be of some
interest to NANOG) was what is supposed to happen to the packets once
they whiz down the DSL wire from the consumer to the phone company
central office, since DSL data, unlike ISDN or regular dialup
connections, doesn't go through the phone switch.  Whoever handles
that IP traffic needs a router or something similar next to the phone
switch to connect to those DSL pairs.  Do the Bells plan to hand all
the traffic to their oh-so-independent ISP subsidiaries?  Will it be

you've got to have colo at the CO. I'm not sure how they're
going to hand off. I would think it would make sense for
CLEC's to do the aggregation of DSL subscription and point
it back to the customer i.e. the ISP pulls a circuit into
our CO, and we split the traffic after carrying it back from
the CO for the ISP.

Disclaimer: I'm thinking out loud. We're about to start DSL
trials and I'm only certain of the colo situation.

We didn't even want to THINK about talking to the telco about co-lo at the
Our solution was to go to a business that is NEXT DOOR to the CO and offer
free/cheap internet in exchange for rack and space on their telco
termination board.
We're getting very good distance on our pairs.
