Description:

The MIB module for managing Trunk Media Gateway.

A Media Gateway is a network element that provides conversion
between the audio signals carried on telephone circuits and
data packets carried over the Internet or over other packet
data networks.

Trunk Media Gateway interface is between the telephone network
and a Voice over IP/ATM network.
The interface on a Trunk Gateway terminates a trunk connected
to PSTN switch (e.g., Class 5, Class 4, etc.).

Media Gateways use a call control architecture where the call
control 'intelligence' is outside the gateways and handled by
external call control elements, called Media Gateway
Controllers (MGCs).
The MGCs or Call Agents, synchronize with each other to
send coherent commands to the gateways under their control.

MGCs use master/slave protocols to command the gateways under
their control. Examples of these protocols are:
* Simple Gateway Control Protocol
* Media Gateway Control Protocol
* Megaco (H.248)
* Simple Resource Control Protocol

To connect MG to MGCs using these control protocols through
an IP/UDP Ports which must be configured. To resolve IP
Addresses, DNS name services may be used.
