MUX Module
The MUX Module multiplexes and demultiplexes the audio, video, data, and control information. Information arrives at the MUX Port in Nx56/64 Kbps channels formatted according to the
Teleservices”).
H.323 video conferences do not require a MUX card. The H.323 card has a build in MUX functionality.
