Re: [nanog] Re: Microsoft offering xDSL access

We are part of the Bell Atlantic ADSL trial in Northern VA -
basically BA has 6 CO's with terminating ADSL modems. This is
aggregated onto a FDDI ring between each CO on cisco's. One of the
CO's has a port into the BA SMDS cloud which is the interconnect
with participating ISP's who also have a port on the SMDS cloud.
So basically, packetize the data as early as possible to get the
20x plus economies of scale vs hauling channelized circuits.

Of course, this is orthogonal to xDSL; the same economies of scale would
apply with T-1 local loops.

Seems to me that for the RBOCs, the big disadvantage of xDSL is losing
all those fat, high-margin T-1 local loop fees.  The advantage is
getting a shot at taking over the Internet business.
