Re: Microsoft offering xDSL access

Jay R. Ashworth sez:

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?

That's correct.  DSL is a baseband technology, running over copper.
Read: layer 1.  The only practical place to put DSL headends right now
is in RBOC CO's.  No one else has the point to point copper -- it's not
a multiplexed layer 1 service like cablemodems.

OR.... You have to be the RBOC. Or subservient to same.

People keep asking me "Why is Hell Titanic so hot on xDSL and
so cold on ISDN?" and this is the reason; with ISDN, you control
who you talk to, with xDSL, THEY do. 

"Hey Ms. ISP, want to compete against bellatlantic.net's offering?
 Rent xDSL connections from us. Period."
