Page 320 of 488 Installing and configuring a Voice Gateway Media Card

Introduction

The Voice Gateway Media Card provides access to the voice gateway and functions as a Follower to the Signaling Server, which is the node Leader and which, by default, acts as a Master for the node. In the absence of the Signaling Server a Voice Gateway Media Card may be an active Leader, a backup Leader, or a Follower. Each customer in a system has only one Leader.

A Voice Gateway Media Card runs the IP Line 3.1 software. It provides voice gateway channels (DSPs) to transcode voice data between IP and TDM (analog/digital). The card’s node properties, as well as the voice gateway channels, must be configured. The cards are installed in a Media Gateway or a Media Gateway Expander.

The Voice Gateway Media Card is represented by a Media Card 32-Port IP Line 3.1/Voice Gateway.

For details, see IP Line: Description, Installation, and Operation (553-3001-365).
