Paging systems  
provides low power dissipation and high reliability. The  
DTMF receiver is based upon the industry standard  
MT8870 monolithic DTMF receiver; the transmitter  
utilizes a switched capacitor D/A converter for low  
distortion, high accuracy DTMF signalling. Internal  
counters provide a burst mode such that tone bursts  
can be transmitted with precise timing. A call progress  
filter can be selected allowing a microprocessor to
