Description
The Mitel MH88622 is a Dual Subscriber Interface
Circuit which provides a complete interface between
the telephone lines a dual codec, requiring a dual rail
supply, battery and dc supply for ringing generation.
The functions provided by the MH88622 includes 2-4
Wire conversion, constant current line feed,
signalling and control. The SLIC manufactured using
thick film hybrid technology which offers high voltage
capability, reliability and high density resulting in a
significant area saving on the printed circuit board. A
complete C.O. type solution can be implemented
with minimal external components. Different variants
are provided to meet different country line
impedance, they are:
