Description
The Mitel MH88520-1 German 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
MH88520-1 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’
(SIL)
optimum circuit board packing density and very high
reliability.
