Let's talk about "conditioned" vs. "unconditioned" lines. Unconditioned
lines could not be used for data transmission above 1200 baud but, a
conditioned line could go above 1200 baud. What is the difference
between the two? You paid more for a conditioned line. What happened in
1984 that as soon as ATT was broken up undonditioned lines could now
support up to 56Kbps? Absolutely nothing.

Modems started doing their own equalization under microprocessor
control and new modulation techniques were developed. A Florida
company called Paradyne was one of the leaders in both new modem
technology and fighting AT&T. Ironically they were bought out by
AT&T.
