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?) Michael
