Ethernet
Also known as IEEE 802.3 Ethernet, this widely-used LAN technology operates at 10Mbps.
endpoint
An H.323 terminal, gateway or Multipoint Controller Unit (MCU). An endpoint can call or
be called and it can generate or end information streams.
FCIF
See CIF.
FECC
Far End Camera Control. This feature enables you to control the camera at the remote
videoconferencing site.
G.711
An ITU standard for speech codecs that provides toll quality audio at 64 Kbps using the
PCM method and either
µ
-law or A-law.
G.723.1
An ITU standard audio algorithm for speech codecs that provides toll quality audio at 5.3 or
6.4 Kbps using the LD-CELP method.
G.728
An ITU standard audio algorithm for speech codecs that provides near toll quality audio
(300–3500 Hz) at 16 Kbps, using the LD-CELP method.
gatekeeper
An H.323 entity that provides address resolution, access control and other services to
endpoints on an H.323 network.
gateway
A network communications system component that translates between H.323 and H.320
protocols, allowing the exchange of voice, video and data between H.323-based
conferencing endpoints on IP networks and H.320-compliant endpoints on circuit-switched
ISDN networks as well as Voice over IP (VoIP).
H.320
The ITU standard for videoconferencing over narrow-band digital networks such as ISDN.
H.320 device
An H.320-compliant entity for transmitting voice and/or video that connects through a
telephone (switched-circuit) network.
