Avaya 700439250 MM710B E1/T1 Media Module for Communication Manager systems.

The Avaya 700439250 is the MM710B E1/T1 Media Module, a digital trunk interface card designed for Avaya Communication Manager platforms. This module provides connectivity for E1 (2.048 Mbps) or T1 (1.544 Mbps) digital trunk lines, enabling integration with PSTN services and inter-PBX networking.

The MM710B is deployed within Avaya G450, G430, and similar media gateway chassis as part of enterprise IP telephony solutions. It handles voice traffic between the Avaya system and external carrier networks or legacy PBX equipment via standard digital trunk interfaces.

This is a legacy media module from Avaya’s Communication Manager portfolio. While still widely deployed in existing enterprise installations, organisations should be aware that Avaya has transitioned much of this product line. The MM710B remains serviceable for maintaining current infrastructure or sourcing replacement units.
