What is the difference between H.248 and H.323? And what are the differences between ATM and FR technologies?

Control Protocol (MGCP). WhatIs.com defines MGCP as follows: 

MGCP is a standard protocol for handling the signaling and session management needed during a multimedia conference. The protocol defines a means of communication between a media gateway, which converts data from the format required for a circuit-switched network to that required for a packet-switched network and the media gateway controller. MGCP can be used to set up, maintain, and terminate calls between multiple endpoints.
