This standard defines the stage two of the Meet-Me Conference (MMC) supplementary service for the pan-European Integrated Services Digital Network (ISDN) as provided by European public telecommunications operators. Stage two identifies the functional capabilities and the information flows needed to support the service description. The stage two description also identifies user operations not directly associated with a call (see CCITT Recommendation I.130 [1]). This standard is specified according to the methodology specified in CCITT Recommendation Q.65 [2]. This standard does not formally describe the relationship between this supplementary service and the basic call@ but where possible this information is included for guidance. In addition this standard does not specify the requirements where the service is provided to the user via a private ISDN. This standard does not specify the requirements for the allocation of defined functional entities within a private ISDN; it does however define which functional entities may be allocated to a private ISDN. This standard does not specify the additional requirements where the service is provided to the user via a telecommunications network that is not an ISDN. The MMC supplementary service provides an user with the ability to arrange for a call between more than two participants@ all participants accessing a conference bridge. No field of application and no conformance is specified to this standard. Therefore no method of testing is available.
