The scope of this Recommendation is the interface between the media controller and media processor in a decomposed multipoint control unit. This Recommendation does not describe the call control functions associated with conferencing services nor does it describe the capabilities of terminals.

The specification of service information for "Dial in" or "Dial out" conferences (e.g., meet me numbers) is out of scope of this Recommendation. It is also assumed that the media controller part of the multipoint control unit is responsible for the management of conference identities.

This Recommendation describes packages and functions associated with the ITU-T H.248 interface for audio, video and data conferencing. This includes the specification of mixing, conference capabilities and core ITU-T H.248.1 protocol usage. The packages and functionality described in this Recommendation are optional according to the rules of [ITU-T H.248.1]. A multipoint control unit may implement one or more of the packages described in this Recommendation.
