Bell MF tone generation and detection tests

What does it do?

These tests are fashioned after those on the CM7291 test tape from Mitel. Those tests are for DTMF, rather than Bell MF, but make a fair starting point for a set of meaningful tests of Bell MF.

These tests include conversion to and from A-law. It is assumed the distortion this produces is comparable to u-law, so it should be a fair test of performance in a real PSTN channel.
