DTMF Transeivers

TheM-8880 is a completeDTMF Transmitter/Receiver that fea- tures adjustable guard time, Automatic Tone burst mode, call progressmode, and a fully compatible 6500/6800microproces- sor Interface The receiver portion is based on the industry stan- dard M-8870 DTMF Receiver, while the transmitter uses a switched-capacitor digital-to-analog converter for low-distortion, highly accurateDTMF signaling. Tone bursts CAN be transmitted with precise Timing by making use of the auto- matic Tone burst mode. To analyze call progress Tones a call progress Filter CAN be selected by an external Microprocessor By Clare, Inc.
