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
generators is 1000 Hz. The QSICOS-program contains a program for generating
coefficients for variable frequencies.
Byte sequences for programming both the tone generators and the bandpass-filters:

The resulting signal amplitude can be set by transmitting the AR1 and AR2 filters. By
switching a ‘digital loop’ the generated sine-wave signal can be fed to the transmit path.
