Two independent tone generators are available per channel. Switching on/off the tone
generators is done by a SOP-Command for CR1-register. The frequencies are
programmed via a COP-Command, followed by the appropriate byte-sequence.
When one or both tone generators are switched on, the voice signal is switched off, if
V+T=0 (CR2) for the selected voice channel. To make the generated signal sufficient for
DTMF, a programmable bandpass-filter is included. The default frequency for both tone
