Glossary 1GGGGlllloooossssssssaaaarrrryyyyaccess line: A telephone line reaching from the telephone company central office to a point usually on yourpremises. Beyond this point the wire is considered inside wiring.analog: In telecommunications, telephone transmission and/or switching that is not digital. An analog phonetransmission is one that was originally intended to carry speech or voice, but may with appropriatemodifications be used to carry data of other types.ANSI (American National Standards Institute): Devises and proposes recommendations for internationalcommunications standards. See also CCITT.AppleTalk: A comprehensive network system designed and developed by Apple Computer, Inc. AppleTalkallows many different types of computer systems, printers, and servers to communicate on a variety of cablingschemes, including LocalTalk and Ethernet cabling. In this manual, AppleTalk refers especially to the protocolsor rule sets that govern this communication.AppleTalk address: A unique identifier for each device using AppleTalk that allows information to be sent andreceived correctly. An AppleTalk address always includes a network number wherever two or more AppleTalknetworks are connected together by routers.AURP (Apple Update-based Router Protocol): An enhanced AppleTalk routing protocol. AURP providesimproved support for AppleTalk over wide area networks (WANs) and tunneling through non-AppleTalk (IP)networks. AURP features include network number remapping, clustering of remote network numbers, and hopcount reduction.backbone: A network topology consisting of a single length of cable with multiple network connection points.bandwidth: The range of frequencies, expressed in Kilobits per second, that can pass over a given datatransmission channel within a network. The bandwidth determines the rate at which information can be sentthrough a channel - the greater the bandwidth, the more information that can be sent in a given amount of time.BAP (Bandwidth Allocation Protocol): Protocol that manages the dynamic bandwidth allocation ofimplementations supporting the PPP Multilink protocol. This is done by defining the Bandwidth AllocationProtocol (BAP), as well as its associated control protocol, the Bandwidth Allocation Control Protocol (BACP). BAPcan be used to manage the number of links in a multilink bundle.baud rate: The rate of the signaling speed of a transmission medium.bit: A binary digit; the smallest unit of data in the binary counting system. A bit has a value of either 0 or 1.bits per second (bps): A measure of the actual data transmission rate. The bps rate may be equal to or greaterthan the baud rate, depending on the modulation technique used to encode bits into each baud interval. Thecorrect term to use when describing modem data transfer speeds.bps: See bits per second.branch: A length of cable in a star network that goes from the center of the star to a wall jack.broadcast: A network transaction that sends data to all hosts connected to the network.burstiness: Data that uses bandwidth only sporadically; that is, information that does not use the totalbandwidth of a circuit 100 percent of the time. During pauses, channels are idle; and no traffic flows acrossthem in either direction. Interactive and LAN-to-LAN data is bursty in nature, because it is sent intermittently,and in between data transmission the channel experiences idle time waiting for the DTEs to respond to thetransmitted data user’s input of waiting for the user to send more data.
