Description
The Mitel MH88510/11 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 MH88510/11 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 which incorporates
various technologies for optimum circuit board and
very high reliability.
