    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) 

At least.  And possible more.  It's not clear that there is an
interoffice trunk between downtown LA and Pasadena.

    and (b) if this is so, then is there any point in getting a higher
	grade line 

No, not at all.  Besides, the quality of the interoffice trunk here is
questionable at best.  I call this same path in reverse all of the time...

    for one's home, when one has no control over the line quality for the other
    2/3 of the connection ?!?
