Abstract

   This document describes an Asynchronous Transfer Mode (ATM) package
   for the Media Gateway Control Protocol (MGCP).  This package includes
   new Local Connection Options, ATM-specific events and signals, and
   ATM connection parameters.  Also included is a description of codec
   and profile negotiation.  It extends the MGCP that is currently being
   deployed in a number of products.  Implementers should be aware of
   developments in the IETF Megaco Working Group and ITU SG16, which are
   currently working on a potential successor to this protocol.
