Managing MultiMedia Calling
Definitions: MMCH features and components
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.

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.
