Battery Feed to the line

Tip Ring reversal capability

Over current protection

Off-Hook detection

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:

Logic interface for SHK, RC, LR, ESE, LCS

Metering injection

Wide V_Batoperating range

Minimum installation space

ESE ramped output
