Description
The Mitel MH88617 is a highly featured, low cost
Subscriber Line Interface Circuit (SLIC). It provides a
total analog transmission and signalling link between
a CODEC and a subscriber line. All functions are
integrated into a single thick film hybrid module,
which provides high reliability and optimum circuit
design needing a minimum of external components.
The line impedance, network balance impedance,
gain
and
