Narrow-band Videoconferencing Systems

This standard prescribes mandatory compliance governing the design, procurement, and engineering of narrow-band videoconferencing systems. It also governs the basic videoconferencing elements of audio, video and graphical communications by providing common formats for compatible audiovisual inputs and outputs, and specifying protocols that will allow a videoconferencing entity to utilize the communications links and synchronization of audio and video signals. This standard applies to Multipoint and Point-to-Point videoconferencing sessions over narrow-band communication services.
