Description
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.
