W
= 1 bit, set high to indicate that the maximum allowed recording time has almost been
reached or has been exceeded (see
SetMaxLengthRecording
command for more
information).
= 1 bit indicating that CallerID information is present. If set to “1” then CallerID
information has been received, decoded and stored inside the CHIPSET and can be
requested by the host.
= 1 bit indicating that the data of the CallerID information could be corrupt because the
calculated and received CRC checksums didn’t match. If set to “1” then the CallerID
information is possible corrupt.
= 1 bit indicating if a certain energy level has been exceeded during the last 30
milliseconds. This bit will be reset immediately again when the energy drops below the
predefined threshold. This can be used as a VAD (Voice Activity Detector). The
threshold is predefined by the “VAD threshold” parameter. The energy is calculated
over the full frequency band.
= 1 bit specifying if a continuous tone has been detected for at least “continuous tone
time” times 30 milliseconds. The “C” flag will only be set to “1” after this
predetermined period of time. The threshold is defined by the “Continuos Tone
coefficient” parameter. This bit will be reset immediately again to “0” when the
continuous tone disappears.
= 1 bit specifying if a tone has been detected within the bandpass frequency during the
last 30 milliseconds (“1” = detected). This bit will be reset immediately again when the
energy drops below the defined threshold. The threshold is defined by the “continuous
tone coefficient” parameter. The energy is calculated after going through a bandpass
filter (300 Hz to 720 Hz).
= 1 bit, indicating a incoming DTMF tone present (“1” = DTMF tone is present). The
sensitivity is predefined by the “DTMF Tone sensitivity” parameter.
DTMF-code
= 4 bits specifying the received DTMF code. Only valid if the “D” flag is set.
