ETSI - PRETS 300 747
Telecommunications Security; Service Access Control and Synchronisation for Audiovisual Services
|Publication Date:||1 February 1997|
This European Telecommunication Standard (ETS) fits into the series of standards about audiovisual communication over the Integrated Services Digital Network (ISDN), which is introduced in the ITU-T H.200 series of Recommendations.
In ITU-T Recommendations H.233  and H.234 , the basic mechanisms for confidentiality and key exchange are specified.
On top of these, this ETS specifies the confidentiality related protocol extensions needed for the establishment, modification and termination of audiovisual conferences using one or more Multipoint Control Units (MCUs).
