MH88630 Overview
The Mitel MH88630 Central Office Trunk Interface circuit provides a plete audio and signalling link between an audio switching equipment and a central office. The loop seize circuitry is controlled by an external input to provide either a loop start or ground start termination. The device is fabricated using thick film hybrid technology to achieve high density circuit design. Programmable audio transmit and receive gain Loop start or ground start termination Selectable 600 Ω or AT&T promise balance network
