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).
