Full screen Video Layout
The full screen view shows one video image. Typically, it displays the remote presentation, or, if there is
no presentation, it displays the other participant or a composite of the other participants.
Gatekeeper
A gatekeeper routes audio and video H.323 calls by resolving dial strings (H.323 alias or URI) into the IP
address of an endpoint, and handles the initial connection of calls. Gatekeepers also implement the dial
plan of an organization by routing H.323 calls depending on their dial prefixes. Scopia Management
includes a built-in Scopia Gatekeeper, while ECS is a standalone gatekeeper.
Gateway
A gateway is a component in a video solution which routes information between two subnets or acts as a
translator between different protocols. For example, a gateway can route data between the headquarters
and a partner site, or between two protocols like the Scopia TIP Gateway, Radvision SIP Gateway, or
the Scopia TIP Gateway.
GLAN
GLAN, or gigabit LAN, is the name of the network port on the Scopia XT Series. It is used on the XT
Series to identify a 10/100/1000MBit ethernet port.
H.225
H.225 is part of the set of H.323 protocols. It defines the messages and procedures used by
gatekeepers to set up calls.
H.235
H.235 is the protocol used to authenticate trusted H.323 endpoints and encrypt the media stream during
meetings.
H.239
H.239 is a widespread protocol used with H.323 endpoints, to define the additional media channel for
data sharing (like presentations) alongside the videoconference, and ensures only one presenter at a
time.
H.243
H.243 is the protocol used with H.323 endpoints enabling them to remotely manage a videoconference.
