12. Appendix C: Glossary and abbreviations
AVB
- Automatic Variable Buffer.
Buffering
- This is a term used to describe a method where data is held in a queue to allow
equalisation of speeds on either side.
CIR
- Committed Information Rate
Codec
- A device, which takes an analogue or digital video signal and converts it into a
serial data bit-stream compatible with a standard data-communications
infrastructure. Codecs used in the Videoconferencing market, also employ a
complex and powerful real-time compression system.
DE
- Discard Eligible
DLCI
- (Data Link Circuit Identifier). A high-level description of a section of the frame
relay structure which defines addressing information.
DTE
- Data Terminal Equipment.
FRAD
- (Frame Relay Access Device). A device, which is designed to take a myriad of
different types of information; e.g. LAN, data, compressed voice and multiplex
them onto a single frame relay data-stream. These devices can often include
switching functionality.
H.320
- An international standard, which defines various functions of encoding and
compression for Videoconferencing applications.
HDLC
- A standard, low-level, synchronous data bit-stream format, used either in its
raw format, or by higher-level data-communications protocols, such as X.25 and
frame relay.
ISDN
- Integrated Services Digital Network.
LAN
- Local Area Network.
