3. The Terminal (CODEC)
A terminal, or a client, is an endpoint
where H.323 data streams and
signaling originate and terminate.
A terminal must support audio
communication; video and data
communication support is optional.

5. The Gateway
The device that converts a traditional
analog telephone call (voice and signals)
into digital data that is sent over an IP
network
Gateway functions include:
◦ Destination lookup: converting a telephone
number to an IP address
◦ IP connection management: the use of protocols
to establish, maintain, and teardown a call
6. The Gatekeeper
A gatekeeper is a very useful, but optional,
component of an H.323-enabled network.
A gatekeeper is often referred to as the
brain of the H.323 enabled network
because of the central management and
control services it provides.
When a gatekeeper exists all endpoints
(terminals, gateways, and MCUs) must be
registered with it. Registered endpoints'
control messages are routed through the
gatekeeper.

Gatekeeper.
7. MCU (Multipoint Control Unit)
A multipoint control unit enables
conferencing between three or
more endpoints.
It consists of a mandatory
multipoint controller (MC) and
zero or more multipoint
processors (MP).
It may be combined into a
terminal, gateway, or gatekeeper.
Call and control signaling are
routed through the MC so that
endpoints capabilities can be
determined and communication
parameters negotiated.
The MCU is required in a
centralized multipoint conference
where each terminal establishes
a point-to-point connection with

8. Streaming Server
A streaming server is
usually a server that
sends media to a
client so the media
can be played back in
real time without
waiting for it to
download completely
first. Examples:
Windows Media, Real,
QuickTime, Flash etc.
