All Known Subinterfaces:

All Known Implementing Classes:

AsyncMediaGroup

public interface SignalGeneratorConstants

extends SignalConstants

Defines the Symbols that name the SignalGenerator params, signals and events. Some figures of interest, to be checked : DTMFs should be 40ms long, at least, so p_Length > 40. DTMFs should be 40ms apart, at least, so p_InterSigGap > 40. DTMFs should be detected down to -23dB, so amplitude > 1/256. Be careful DTMFs are generated in 16 bit range, whether compressed in A- ou mu- law, the available p_Amplitude could be 32767 (15 bits unsigned), 2047 (11 bits), 4095 (12). Thus, p_Amplitude > 256.0 might do in all cases...

Since:

OCMP 2.2
