20.2. Connection model
The connection model for the protocol describes the main objects within a media gateway as terminations and contexts that can be controlled by the media gateway controller. A termination sources or sinks[] one or more streams, and each termination holds information about the actual media streams.
[] In layman terms: either originates or terminates.
Different terminations are linked together by a context. The set of terminations that are not associated with other terminations are defined as being represented by a special type of context (namely, the null context). A context describes the topology of terminations associated with it: for example, it includes parameters about mixing in case the context contains more than two terminations.
