What is a Gatekeeper?
A gatekeeper as defined by the ITU-T H.323 standards
is an optional device that provides access and
bandwidth usage controls for H.323 devices on an IP
network.
May also provide address lookup and translation,
conference accounting, and site/conference status
information.
It is the key element in the network that allows
endpoints to find other endpoints, gateways, and to
join multipoint conferences

Unit Operation - Conference Modes
VOICE SWITCH
All audio from all participants is mixed within the MCU
and distributed. The loudest audio stream is selected and
video from this participant is broadcast to all other
participants.
FIXED
BROADCAST
Video from a selected participant is broadcast to all
other participants regardless of audio (audio continues
to be mixed and distributed). This feature is available
only through the Web management interface.
CONTINUOUS
PRESENCE
Video from the four loudest sites is sent simultaneously
to every terminal in the conference (in QCIF format).
Each terminal combines the four signals into a single,
quadranted display. Audio continues to be mixed from
ALL sites and distributed back to ALL sites.
