The following occurs in my hypothetical system:
Quote from Jason [cincydsp@gmail.com]:
"If you allow the various phase-modulation signals to have multiple
phases and therefore carry information, then all you have is an enormous
set of parallel phase-modulated channels. As long as you had the
infrastructure in the PSTN network to support the connections, then you
would get linear scaling of total "bits/sec" capacity with the number of
phone lines."
