Avaya 700466634 MM710B T1 E1 G450 Media Module

Avaya MM710B T1/E1 Media Module for the G450 Branch Gateway (part number 700466634) provides a single T1 or E1 trunk port to terminate DS-1 trunks within an Avaya CM environment, enabling PRI connectivity for enterprise voice routing. Designed for use in the G450 Branch Gateway (and compatible with G430 deployments), this module slots into the gateway to connect T1 or E1 trunks to private networks or the PSTN. The MM710B is cataloged under part numbers 700466634 and 700439250, reflecting its role as a one-port T1/E1 trunk module, and is described in Avaya hardware references as terminating a T1 or E1 trunk in the G450 gateway. In signaling terms, the device follows standard DS-1 framing with line coding options commonly used for T1/E1 configurations (T1 line coding: AMI/ZCS/B8ZS; E1 line coding: HDB3), and it is documented by Avaya as a supported media module for the G450/CM deployment. The MM710B leverages the universal DS-1 concept to support T1 and E1 interfaces in a single module, aligning with Avaya’s hardware descriptions for branch gateways and ensuring compatibility with ITU-T G.703 and ANSI T1 framing as applicable.
