Avaya MM710 700439250 T1/E1 Media Module

Preserve critical voice connectivity on the Avaya G430 Media Gateway with the MM710 T1/E1 Media Module. This hot-swappable module provides one T1/E1 WAN interface and is designed for environments that still rely on circuit-based transport for voice services, PRI access, or gateway integration. The value here is continuity. Instead of forcing a platform change, the MM710 extends the life of an installed gateway with the interface needed to keep existing carrier services in place. That matters in branch offices, distributed enterprises, and migration projects where voice cutovers must be controlled and downtime is expensive. Avaya’s marketing information notes support for the combined features of a DEFINITY DS1 circuit pack, with ISDN PRI support for T1 or E1 revenue-associated options. For teams maintaining mixed telephony estates, that makes the module a focused, infrastructure-grade component rather than a generic adapter. It is built for the realities of enterprise voice: compatibility, service continuity, and predictable operation inside a supported gateway platform.
