MH88631 - Central Office Interface (LS/GS) Preliminary Information

General Description

The Mitel MH88631-1, 2 Central Office Trunk Interface circuit provides a complete audio and signalling link between audio switching equipment and a central office.

The loop seize circuitry is controlled by an external input to provide either a loop start of ground start termination.

Key Features

  • Transformerless 2-4 wire conversion Line state detection outputs - forward current - reverse current - ring ground - tip ground - ringing voltage Programmable audio transmit and receive gain Loop start or ground start termination Selectable 600 Ω or AT&T compromise balance network -1 version: 20Hz Ringing Voltage -2 version: 50Hz Ringing Voltage ISSUE 4 April 1995 Ordering I.
