Description\nThe MT8924 is designed to provide conference call capability in digital switching systems. It allows up to 10 independent conferences to be set for up to 32 PCM voice channels.\nA/μ-Law companded data from the PCM input port is converted to linear format, processed by a dedicated arithmetic unit, re-converted to companded format and then sent to the PCM output port.The PCM output signal contains all the information of each channel connected in conference except its own.\nProgrammable attenuation and noise suppression are provided for channels connected in conference or transparent mode. Additionally, an input for an external tone is featured that can be used as a signal to indicate to connected parties that they are on a conference call.
