by compressing the data to a smaller footprint and compensating for packet
loss.
Restricted Mode Restricted mode is used for ISDN endpoints only, when the PBX and line
uses a restricted form of communication, reserving the top 8k of each
packet for control data only. If enabled, the bandwidth values on these lines
are in multiples of 56kbps, instead of multiples of 64kbps.
Room System A room system is a hardware videoconferencing endpoint installed in a
physical conference room. Essential features include its camera's ability to
PTZ (pan, tilt, zoom) to allow maximum flexibility of camera angles enabling
participants to see all those in the meeting room or just one part of the
room.
RTCP Real-time Control Transport Protocol, used alongside RTP for sending
statistical information about the media sent over RTP.
RTP RTP or Real-time Transport Protocol is a network protocol which supports
video and voice transmission over IP. It underpins most videoconferencing
protocols today, including H.323, SIP and the streaming control protocol
known as RTSP. The secured version of RTP is SRTP.
RTSP RTSP or Real-Time Streaming Protocol controls the delivery of streamed
live or playback video over IP, with functions like pause, fast forward and
reverse. While the media itself is sent via RTP, these control functions are
managed by RTSP
Sampling Rate The sampling rate is a measure of the accuracy of the audio when it is
digitized. To convert analog audio to digital, it must collect or sample the
audio at specific intervals. As the rate of sampling increases, it raises audio
quality.
SBC A Session Border Controller (SBC) is a relay device between two different
networks. It can be used in firewall/NAT traversal, protocol translations and
load balancing.
Scalability Scalability describes the ability to increase the capacity of a network device
by adding another identical device (one or more) to your existing
deployment. In contrast, a non-scalable solution would require replacing
existing components to increase capacity.
