Description  
Dial pulse detection  
The Mitel MH88500 Subscriber Line Interface Circuit  
provides a complete interface between the telephone  
line and a speech switch requiring only single  
bidirectional switch per crosspoint. The functions  
provided by the MH88500 include bidirectional  
differential to single ended conversion in the speech  
path, line battery feed, ringing feed and loop and dial  
pulse detection. The device is fabricated as a thick  
film hybrid in a 20-pin ‘single-in-line’ package  
allowing optimum circuit board packing density.
