Okay, now lets talk about a wide-scale xDSL implementation using a
reasonably well known POP architecture like UUNet's.
If xDSL can only run about 18kft end-to-end, to service a wide metro area
like Washington, D.C. one would either have to have a POP within every 6
mile radius (fed by conventional circuits) or backhaul the data (by
conventional circuit) to their POP.
Is this correct, if not, what am I missing?
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
