IEEE 802.3 standard for the use of Ethernet LAN technology over Unshielded 

Twisted Pair wiring, running at 10 Mbps.

Address Resolution Protocol. An Internet protocol used to bind an IP address to Ethernet/

802.3 addresses.

American Standard Code for Information Interchange. It is an 8-bit code for character 

representation.

Attachment Unit Interface. An IEEE 802.3 transceiver cable connecting the network 

device (such as a router) to the MAU (media access unit). 

Feature providing the capability of adjusting the bandwidth (opening 

or closing multiple B channels) when the load in traffic increases or decreases.

In ISDN, a full-duplex, 64 Kbps channel used for sending user data.

Basic Rate Interface. The ISDN interface providing two 64 Kbps B channels for voice, 

data and video transmission and one 16 Kbps D channel for signaling and data transmission.

A device that segments network traffic. A bridge maintains a list of each node on the 

segment and only traffic destined for a node on the adjacent segment is passed across the bridge. A 
bridge operates at Layer 2 of the OSI reference model.

Challenge Handshake Authentication Protocol. A security protocol supported under 

point-to-point protocol (PPP) used to prevent unauthorized access to devices and remote networks. 
Uses encryption of password, device names and random number generation.

Data Communicating Equipment. Equipment used within a network to transfer data from 

source to destination such as modems.

In ISDN, a full-duplex 16 Kbps channel used for link setup.

Techniques used to reduce the number of bits transferred across the 

communication links that represent the actual data bits. Compression is used to optimize use of 
WAN links and speed data transmission.
