prSSH ETS 300 483:1996 ed.1

Terminal Equipment (TE); Integrated Services Digital Network (ISDN); Multipoint communications for audiovisual services; Main functionalities and basic requirements for Multipoint Control Units (MCUs)

Scope

This ETS specifies the functional requirements applicable to a Multipoint Control Unit (MCU), or a set of interconnected MCUs, which allows several audiovisual terminals to communicate simultaneously using single or multiple digital channels up to 1 920 kbit/s when interconnected through the pan-European Integrated Services Digital Network (ISDN). This ETS specifies the basic in-band signalling procedures to be supported to control the operation of MCU and audiovisual terminals involved in a simple multipoint communication or a basic video/ audiographic conference as specified in other standards.
