DTMF
DTMF, or touch-tone dialling, is the tones you hear when you dial on a touch-tone telephone.
Dual Video
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.
E.164
E.164 is an address format for dialling an endpoint with a standard telephone numeric keypad, which
only has numbers 0 - 9 and the symbols: * and #.
Endpoint
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 XT Executive, software endpoints
like Scopia Desktop Client, mobile device endpoints like Scopia Mobile, room systems like XT Series,
and telepresence systems like Scopia XT Telepresence.

FEC
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 Elite MCU)
to manage up to ten percent packet loss in the video stream with minimal impact on the smoothness and
quality of the video.
FECC
Far End Camera Control (FECC) is a feature of endpoints, where the camera can be controlled remotely
by another endpoint in the call.
