Glossary

10Base2

IEEE 802.3 specification, similar to Ethernet, using thin coaxial cable that runs at 10 Mbps, with a maximum distance of 185 meters per segment. Also known as Thin Ethernet or Thinwire Ethernet.

10BaseT

IEEE 802.3 specification, using unshielded twisted-pair cabling and running at 10 Mbps.

AEP

AppleTalk Echo Protocol. Allows a node on an AppleTalk network to send a packet to another node and in return, receive an echoed copy of the packet.

B-Channel

64 kbps bearer channel used for voice, circuit, or packet switched data.

bearer service

As defined by CCITT standards, a type of telecommunication service that pro- vides the capability for the transmission of information between user-to-net- work interfaces. Bearer services defined for ISDN are circuit mode and packet mode.

BOOTP

The Bootstrap Protocol allows a network node to determine certain startup in- formation such as its IP address.

Bridge

A data communications device that connects two or more networks. A bridge stores and forwards complete packets between the networks. Bridges operate at the data-link layer of the OSI model.

CCITT

Consultative Committee on International Telephony and Telegraphy. A body of the International Telegraph Union (ITU) which prepares recommendations, commonly referred to as international standards, to resolve technical tele- graph and telephone problems.
