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.
