      "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.";
