The TN744C contains eight ports of tone detection on the Time Division Multiplexing (TDM) bus that function the same as the TN2182. The difference is the TN744C does not support call progress, tone generation, or clocking. The TN744C processor supports digital signal processing of Pulse Code Modulated (PCM) signals on each port to detect tones and other signals. Generation of tones is also supported for applications such as Release 2 Multi-Frequency Compelled (R2-MFC), Spain MF, and Russia MF. Gain (or loss) and conferencing can be applied to PCM signals received from the TDM bus. Additional support includes DTMF detectors to collect address digits during dialing, and A-Law and Mu-Law companding.
