This is for Datapac-3101 service (i.e. they do PAD work for you), not
Datapac-3000 (you do your own PAD).  For the latter, rates are about 0.60$/kp
within Ontario (location-sensitive), which changes the picture somewhat.
However, to the U.S. there is much more of a balance, at that point the
precise billing schemes on phone lines become very important -- for example
uunet charges for 3 minutes minimum per call.  Also remember that it is
more expensive to have an empty call with a Telebit (1-2 minutes) than with
UUCP/X.25 (50 packets?).  It gets complicated.  I think that with 1 minute
minimum and night rates, TB's win out.  Otherwise it gets pretty fuzzy which
is better.  Oh yes, remember to factor in the monthly charges if you do
your own PAD work, you need nontrivial volume for them to disappear in the
wash.
