2 problems.
1. On a PER CALL, not per line basis, how will they tell if it is a modem
call versus a voice call?

2. My local company (GTE, los angeles) told me 4 years ago that they no
longer needed, nor cared, for information about modems because they
had upgraded their equipment.

Now, I know that the electronic switching systems can tell in one second
if a constant tone is on the line (and they use that to stop phreakers).
My question is: Without paying attention to the type of tone, and in
doing so violating privacy, how can they tell if someone is humming
or if a modem is squaking? (And what about trailblaizers which are not
constant tones?)
