data terminal equipment. Device at the user end of a user−network interface that serves as a data source,

destination, or both. DTE connects to a data network through a DCE device (for example, a modem) and

typically uses clocking signals generated by the DCE. DTE includes such devices as computers, protocol

translators, and multiplexers.

10BaseT

10−Mbps baseband Ethernet specification using two pairs of twisted−pair cabling (Category 3, 4, or 5): one

pair for transmitting data and the other for receiving data. 10BaseT, which is part of the IEEE 802.3

specification, has a distance limit of approximately 328 feet (100 meters) per segment.

ASIC

Application Specific Integrated Circuit, a chip designed for a particular application. ASICs are built by

connecting existing circuit building blocks in new ways

ATM

Asynchronous Transfer Mode. International standard for cell relay in which multiple service types (such as

voice, video, or data) are conveyed in fixed−length (53−byte) cells. Fixed−length cells allow cell processing

to occur in hardware, thereby reducing transit delays. ATM is designed to take advantage of high−speed

transmission media such as E3, SONET, and T3.

Attachment Unit Interface (AUI)

attachment unit interface. IEEE 802.3 interface between an MAU and a NIC. The term AUI can also refer to

the rear panel port to which an AUI cable might attach. Also called transceiver cable.

Attachment Unit Interface

AWG

American Wire Gauge

Basic Rate Interface (BRI)

Basic Rate Interface. ISDN interface composed of two B channels and one D channel for circuit−switched

communication of voice, video, and data.

BNC

BNC coonector. Standard connector used to connect IEEE 802.3 10Base2 coaxial cable to an MAU.
