Essentially we are really just talking about a certain level of "fidelity"
between your hardware and the telco hardware.
The real question is WHAT does the person hope to accomplish.
Please respond to Tim directly at

Certainly the use of a coupler limits the bandwidth of the signal
that can be reliably exchanged. It worked in the days of two-tone
300 baud, but I don't think it would stand a chance at 4800, 9600
or above.
