Multimedia call
A multimedia call, for MMCH, is one that conforms to the H.320 and T.120 suite
of protocol standards. These standards allow video-conferencing packages from
different vendors to communicate with one another. The capabilities of the
individual multimedia-endpoint package can vary, however.
■An H.320 call can contain voice, video and data.
■The bandwidth for MMCH calls is limited to 2 B-channels.
Figure 9. MMCH multimedia complex
Basic multimedia complex
A Basic multimedia complex consists of a BRI-connected multimedia-equipped
PC and a non-BRI-connected multifunction telephone administered in Basic
mode. With a Basic multimedia complex, users place voice calls at the
multifunction telephone and multimedia calls from the multimedia equipped PC.
Voice calls will be answered at the multifunction telephone and multimedia calls
will alert first at the PC and, if unanswered, will next alert at the voice station. A
Basic multimedia complex provides a loose integration of the voice station and
H.320 DVC system.
