`Data Service Unit DSU Device designed lo connect a DTE (Oala Terminal Equipment like a PC or a LAN) lo a d1g1tal phone
`fme to allow fully-digllal communications A DSU 1s sort ol lhe d1g1tal eQu1valen1 of a modem In more technical terms a DSU
`1s a type of short haul. synchronous data fine driver. normally installed at a user location lhal connects a user's synchronous
`equipment over a 4 wire circuit lo a servinQ dial central-01t1ce This service can be tor a point to-point or muthpoml opcra11on
`In a d1g1tal data network DSUs are typically used !or leased lrnes. For switched d1g1lal services, you need a CSU/OSU also called
`a DSU/CSU See CSU/DSU and DSU/CSU

`Data Terminal Equipment DTE. A delin11ion 01 hardware specrlicallons lhaf provides for data communications. There are
`two basic specs your hardware can conform lo, DTE (Data Termlnal Equipment) or □CE (Dala Communicauons Equipment) See
`DCE and DTE

`Data Transfer Time The time that elapses between the Initial oftenng of a unit of user data 10 a nelwork by transmitting data
`terminal equipment and the complete delivery of Iha! unit to receiving data lerminal equ1pmen1
`Data Typing When converhng a database lrom one formal lo another, several conversion programs will convert the data to a
`common formal before converting 1t to the linal version During the conversion process a program may check through lhe data
`m the database lo determine whal 1l rs and arbitrarily make one field numeric, one lleld character, one lteld memo, etc
`Data Warehouse A database warehouse consolidates information from many departments within a company This data can
`either be accessed quickly by users or put on an OLAP server lor more thorough analysis. Data warehouses often use OLAP
`servers OLAP stanr1s for On Line Analytical Processing, also called a mullld1menslonal database. According to PC Week. lhese
`databases can slice and dice reams of data to produce meamnglul results that go lar beyond what can be produced using lhe
`traditional two-d11nens1onal query and reporl loots fhal work with most relallonaf databases OLAP data servers are best suited
`to work with da1a warehouses See DATA WAREHOUSING.
`Data Warehousing A sollware strategy in which data are extracted from large transactional databases and other sources
`and stored in smaller dalabases, making analysis ol the data somewhat easier See DATA WAREHOUSE
`Database A collecl1on al data slruclured and organized in a d1sc1plmed fashion so that access 1s possible quickly to mfor(cid:173)
`ma11on of interest There are many ways of organizing databases Most corporate databases are nor one single, huge file They
`are multiple databases related to each other by some commo11 thread e.g an employee 1dcnhl1callon number. Databases are
`made up of two elements, a record and a lield A record 1s one complete entry 1n a database, e.g Gerry F11esen. 12 West 21

`Stored Program Computer A computer controlled by 1mernally slored 1nslruct,ons thal can synthesize and store inslruc(cid:173)
`tions. and lhat can subsequently execute those ,nstruct1ons See also STORED PROGRAM CONTROL
`Stored Program Control SPC The routinµ ol a phone call through a switching matrix is handled by a program stored in a
`computer-like device. whrch may well be a special-purpose computer Before SPC switches came along. the rotary dialing of the
`phone caused the elements of the switch to directly step" through their dialing palh This was slow and cumbersome. since d1al-
`1ng can be slow Also subscribers can abort hall way (they made a mistake) and this can mess up lhe sw,lch's eff1c1ency Thus the
`move to stored program control switches was very s1gml,cant These days virtually all switches as stored program control Nothing
`happens in lhe sw1tch1ng matrix unlll lhe stored proaram conlrol receives all !he dialing digits and decides what to do with them
`Stovepiplng In a call center, agents typically need access to many databases In the past they've used dumb terminals. They
`log into one computer, get into one database go lurther into 1t When they need information out of another database, they've typ•
`1cally had to climb out of the previous database, the previous computer, log into another and climb down into 11 This is called
`stovep1ping because 11 follows the contours ol a stovepipe These days, agents have intelligent computers as terminals They
`can access several databases at once, by simply having different windows open on their screen or having a front end program
`lhal populates a screen with information from several databases, most likely using a GUI 1nlerlace.
`STP 1 Shielded Twisted Pair Twisted pair (TP) w,rrng with a metal foil sheath around it lo limit interference.
`2 Signal Transfer Point The packet switch 1n the nation's emerging Common Channel Interoffice Signaling (CCIS) system The
`CCIS is a packet switched network operatmg at 4800 bits per second CCIS replaces both SF (Single Frequency) and MF (Mult1-
`frequency) by converting dialed d1g1ts to data messages ll will run al 56,000 bps with the mlroducl1on of Signaling System 7

`Straight-Through When wiring up phone and some data extensions. !here are basically two ways of doing it -
`straight(cid:173)
`through and crossover. Straight-through occurs when you wire both ends identically so the signals pass straight through This
`1s typically done w1lh patch panels and modular EIA adapters. Crossover wiring has a reverse order of w111ng As an example,
`let's take a lour conductor. RJ-11 In a crossover w111ng (e.g. an RJ-11 phone extension cord), conductor 1 would be connected
`to hole 1 on one plug and one 4 on the other end Conductor 2 would be connected to 4 And 3 would be connected lo hole 2
`Straight• Tip Connector ST Connector An optical fiber connector used lo join single fibers together at interconnects or to
`connecl them to optlcal cross connects.
`Straightforward Outward Completion Operator can place an outgoing call for phone user Also called 'Through

`Strand Loy The distance of advance of one strand of a spirally stranded conductor, m one turn. measured axially.
`Stranded Conductor A conductor composed of groups of wires twisted together
`Stranded Copper A type ol electrical wire conductor compnsed ol multiple copper wires twisted together forming a single
`conductor and then covered wrth an insulating Jackel
`Stranded fiber Cable A fiber cable m which 1ndiv1duat optical fibers are twisted around strength members. Both campus
`and building versions are used The campus version unlike the one lor buildings, 1s env1ronmenlally protected for outside use.

`Stream An SCSA term One of 16 physical data lines making up the SCbus or SCxbus Data Bus.
`Streamer Streaming tape dove
`Streaming An Internet term. A Web page typically consists of text and graphics images. To receive the text typically takes
`much less time than rece1v1ng the graphics images One ot lhe features which Netscape's improved browser introduced was the
`streaming of graphical Image This allowed the user to look at a new page of text on screen as the graphics streamed in (came
`In over the phone lines) See INTERNET and HOME PAGE
