Tandberg Video on Frame Relay

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. Pixelation
