Generally yes. Of course it's up to telco to multiplex delivery of service
as they see fit. If an ISP wants to suffer the hassle of hundreds of analog
lines, telco can still use fiber optic or T1s and a mux. Larger ISPs know
better and don't take delivery on analog lines.
If you say the magic word Centrex, as Mike Bilow noted, then telco suddently
becomes your friend. However, they dislike ISPs and that dislike is
intensifying. At some point the ISP-ness overcomes the Centrex-ness and you
again become the enemy. In some places Centrex tariffs can apply to PRI,
but whether that is cheaper or costlier than ordinary PRI is again a local
variable. It's hard to generalize. Until 1995, for instance, PacBell had
an $800/month or so surcharge on PRIs that were part of Centrex. That's
history; PacBell PRI is now rather competitive, though like everybody else
they tend to be sold out (and waiting for Lucent and Nortel to deliver more
parts), so delivery often isn't exactly speedy.

Exactly. Average usage varies widely among ISPs. My suspicion is that the
flat rate ones tend to deliver more busies, too. If there's any kind of
pay-per-time component, the ISP has an extra incentive to add capacity. Now
this is potentially one reason telcos don't like flat rates, but in practice
they're obligated to provide good grades of service, so they view heavy
users as a burden, not as good customers. (Remember, monopoly telcos don't
have customers, just subscribers on a good day and ratepayers on a bad day.)

And this is a very reasonable structure; it is "free use" to all but the
heaviest users. If you don't expect to hit 120 hours you don't even think
about it. That is also the charm of "flat rate" local telephone service.
And the ones who never hang up are the ones who are discouraged by threshold
pricing. I consider threshold pricing to be a good alternative to measured
service, and that's NOT the same as BA's Telpak pricing. I'm trying to
convince NYNEX of the same. The "I want to sell ISDN but the boss hates
flat rates" faction is interested in threshold rates, and understands that a
200 hour threshold does not mean that the price is 200 times the hourly
measured rate or even the hourly incremental cost. Average usage is way
below that, and the price, to be profitable, need merely exceed the average
cost. Of coruse the more senior people are in the "we want all service
measured so we're gonna start with this hokey computer hacker stuff".
Of course the ISP business is very competitive so Mr. Sechrist's business
has evolved to balance profit margins against customer satisfaction. Telcos
are still stuck in the rut of monopoly thinking, carrier versus ratepayer.
