2.2.4.1 Tone Generation Architecture
The ASP contains a universal tone generator which can be used for tone alerting, call
progress tones, DTMF-signals or other audible feedback tones.
For the receive channel, a universal switching to each signal path (earpiece,
loudspeaker and piezo ringer) is implemented. In the earpiece and loudspeaker
direction, an addition of the programmed tone sequence (sine-wave, trapezoid,
square-wave and DTMF) with the incoming voice signal is possible.
For the transmit direction, a supplementary DTMF-generator is implemented. If the
DTMF-generator is active (TGSR.DTMF = 1), only a part of the tone generator (TG) is
available for the receive direction (one or two tone sequences). In addition, a universal
switching to the transmit path is also possible (TGSR.TRX).
All the tone generation configurations are programmable in the registers TGCR and
TGSR (see description in chapter 4). A signal flow graph of the ARCOFI-tone generation
unit is shown in figure 19.
The tone generation can be subdivided into five main blocks:
A detailed description of the five main tone generation blocks follows in the next
sub-sections.
