I beg your pardon, but it is not:

Obviously, this refers to aDSL.  Unfortunately, many parties who should
know better use the terms "DSL" and aDSL synonymously.

Allow me to refresh your memory:  We were speaking specifically of SDSL.

That is true but not relevant to the present discussion.

> If your xDSL cable provider offers you 2Mbps SDSL, you need clarification:

To refresh your memory, (1) Best Internet (over Northpoint cabling service)
provides approximately 1.1 Mbps service over an SDSL line to my place of
residence, 744 Harrison, San Francisco.  (Again, the initial "S" stands 
for "symmetric".)  Separately, (2) At my former firm, I had a 2 Mbps HDSL
line over existing CAT3 cabling across the office building, internal to
the firm's LAN.

I hope that alleviates any confusion.
