Xerox WorkCentre 7132 System Administration Guide 17517 GlossaryThis chapter contains a list of terms used in the System Administration Guide. Eachterm has a corresponding definition that reflects the meaning of the term as it is usedin this Guide.Terms DefinedUse the following definitions to learn more about the meanings of terms used in thisGuide.10Base-T 10-Mbps baseband Ethernet specification using two pairs oftwisted-pair cabling: one pair for transmitting data and theother for receiving data. 10Base-T, which is part of the IEEE802.3 specification, has a distance limit of approximately 100meters per segment. See also Ethernet and IEEE.100Base-TX 100-Mbps baseband Fast Ethernet specification using twopairs of either UTP or STP wiring. The first pair of wires isused to receive data; the second is used to transmit. Toguarantee proper signal timing, a 100Base-TX segmentcannot exceed 100 meters in length. Based on the IEEE 802.3standard. See also Ethernet, and IEEE.1000Base-TX 1000Base-T uses all four cable pairs for simultaneoustransmission in both directions through the use of echocancellation and a 5-level pulse amplitude modulation (PAM-5) technique.In 1999, the 802.3ab standard (1000Base-T) allows GigabitEthernet to run over Category 5 copper cable, enabling GigEdevices to be readily installed in 100BaseT networks withoutcable changes. The maximum distance between nodes isbased on the type of transceiver and cable used.ASCII An abbreviation of American Standard Code for InformationInterchange. A coding scheme that assigns numeric values toletters, numbers, punctuation, and certain other characters.Auditron A tracking system, which is built into the machine. You canuse Auditron to track overall machine usage, individual usage,and usage of each feature separately.BOOTP An abbreviation of Bootstrap Protocol. This is a protocol usedby a network node to determine the IP address of its Ethernetinterfaces, in order to boot a computer from a server via anetwork.
