A DNS server is responsible for resolving domain names in your network by
translating them into IP addresses.
DTMF, or touch-tone, is the method of dialing on touch-tone phones, where
each number is translated and transmitted as an audio tone.
Dual video is the transmitting of two video streams during a
videoconference, one with the live video while the other is a shared data
stream, like a presentation.
The dynamic video layout is a meeting layout that switches dynamically to
include the maximum number of participants it can display on the screen
(up to 9 on the XT Series, or up to 28 on Scopia
image always shows the active speaker.
E.164 is an address format for dialing an endpoint with a standard
telephone numeric keypad, which only has numbers 0 - 9 and the symbols:
* and #.
An endpoint is a tool through which people can participate in a
videoconference. Its display enables you to see and hear others in the
meeting, while its microphone and camera enable you to be seen and
heard by others. Endpoints include dedicated endpoints, like Scopia
Executive, software endpoints like Scopia

Forward Error Correction (FEC) is a proactive method of sending redundant
information in the video stream to preempt quality degradation. FEC
identifies the key frames in the video stream that should be protected by
FEC. There are several variants of the FEC algorithm. The Reed-Solomon
algorithm (FEC-RS) sends redundant packets per block of information,
enabling the sender (like the Scopia
percent packet loss in the video stream with minimal impact on the
smoothness and quality of the video.
Far End Camera Control (FECC) is a feature of endpoint cameras, where
the camera can be controlled remotely by another endpoint in the call.
See FEC on page 47.

Frames Per Second (fps), also known as the frame rate, is a key measure
in video quality, describing the number of image updates per second. The
