I live in the 213 Area code in L.A.  I recently moved, and want to get two
lines for my new abode, one of which I will use exclusively for a modem
line.  When I talked to Pacific Bell I was told I could (for a nice high
fee, of course) get a `Data Access Line' which would (presumably) run from
the local switching office to my home; a higher grade line would replace the
normal voice grade phone line.  I was told that this was recommended for
anyone doing data transmissions of 2400 baud or higher.  I almost bit; but
then I thought, what about the rest of the way?  I would be calling JPL in
Pasadena 99% of the time, which is in Area code 818, prefix 354.  Since I'm
not a TELECOM expert, I just surmised that the calls I would make would go
from my home, over my `good' data line, to the local switching office; then
to whatever the local switching office for Pasadena is, and then over a 
(presumably) standard voice grade line to my other modem.
 
My question for you experts is (a) is this something like the real path that
the call will take (3 hops; home <=> switching office <-> s.office#2 <-> work)
and (b) if this is so, then is there any point in getting a higher grade line
for one's home, when one has no control over the line quality for the other
2/3 of the connection ?!?
 
Direct replies appreciated ...
