Text of the page (random words):
nly two telephones per telephone call and used circuits of fixed bit rates modern services can be multimedia multi point and multirate these aspects are examined individually in the following three sub sections 9 multimedia edit a multimedia call may communicate audio data still images or full motion video or any combination of these media each medium has different demands for communication quality such as bandwidth requirement signal latency within the network and signal fidelity upon delivery by the network the information content of each medium may affect the information generated by other media for example voice could be transcribed into data via voice recognition and data commands may control the way voice and video are presented these interactions most often occur at the communication terminals but may also occur within the network 3 7 multipoint edit traditional voice calls are predominantly two party calls requiring a point to point connection using only the voice medium to access pictorial information in a remote database would require a point to point connection that sends low bit rate queries to the database and high bit rate video from the database entertainment video applications are largely point to multi point connections requiring one way communication of full motion video and audio from the program source to the viewers video teleconferencing involves connections among many parties communicating voice video as well as data offering future services thus requires flexible management of the connection and media requests of a multipoint multimedia communication call 7 8 multirate edit a multirate service network is one which flexibly allocates transmission capacity to connections a multimedia network has to support a broad range of bit rates demanded by connections not only because there are many communication media but also because a communication medium may be encoded by algorithms with different bit rates for example audio signals can be encoded with bit rates ranging from less than 1 kbit s to hundreds of kbit s using different encoding algorithms with a wide range of complexity and quality of audio reproduction similarly full motion video signals may be encoded with bit rates ranging from less than 1 mbit s to hundreds of mbit s thus a network transporting both video and audio signals may have to integrate traffic with a very broad range of bit rates 7 9 a single network for multiple services edit traditionally different telecommunications services were carried via separate networks voice on the telephone network data on computer networks such as local area networks video teleconferencing on private corporate networks and television on broadcast radio or cable networks these networks were largely engineered for a specific application and are not suited to other applications for example the traditional telephone network is too noisy and inefficient for bursty data communication on the other hand data networks that store and forward messages using computers had limited connectivity usually did not have sufficient bandwidth for digitised voice and video signals and suffered from unacceptable delays for the real time signals television networks using radio or cables were largely broadcast networks with minimum switching facilities 3 7 it was desirable to have a single network for providing all these communication services to achieve the economy of sharing this economy motivates the general idea of an integrated services network integration avoids the need for many overlaying networks which complicates network management and reduces flexibility in the introduction and evolution of services this integration was made possible with advances in broadband technologies and high speed information processing of the 1990s 3 7 while multiple network structures were capable of supporting broadband services an ever increasing percentage of broadband and multiple system operator mso providers opted for fibre optic network structures to support both present and future bandwidth requirements catv cable television hdtv high definition television voip voice over internet protocol and broadband internet are some of the most common applications now being supported by fibre optic networks in some cases directly to the home ftth fibre to the home these types of fibre optic networks incorporate a wide variety of products to support and distribute the signal from the central office to an optic node and ultimately to the subscriber end user broadband technologies edit telecommunications edit in telecommunications a broadband signalling method is one that handles a wide band of frequencies broadband is a relative term understood according to its context the wider or broader the bandwidth of a channel the greater the data carrying capacity given the same channel quality in radio for example a very narrow band will carry morse code a broader band will carry speech and a still broader band will carry music without losing the high audio frequencies required for realistic sound reproduction this broad band is often divided into channels or frequency bins using passband techniques to allow frequency division multiplexing instead of sending a higher quality signal in data communications a 56k modem will transmit a data rate of 56 kilobits per second kbit s over a 4 kilohertz wide telephone line narrowband or voiceband in the late 1980s the broadband integrated services digital network b isdn used the term to refer to a broad range of bit rates independent of physical modulation details 10 the various forms of digital subscriber line dsl services are broadband in the sense that digital information is sent over multiple channels each channel is at a higher frequency than the baseband voice channel so it can support plain old telephone service on a single pair of wires at the same time 11 however when that same line is converted to a non loaded twisted pair wire no telephone filters it becomes hundreds of kilohertz wide broadband and can carry up to 100 megabits per second using very high bit rate digital subscriber line vdsl or vhdsl techniques 12 modern networks have to carry integrated traffic consisting of voice video and data the broadband integrated services digital network b isdn was designed for these needs 13 the types of traffic supported by a broadband network can be classified according to three characteristics 14 bandwidth is the amount of network capacity required to support a connection latency is the amount of delay associated with a connection requesting low latency in the quality of service qos profile means that the cells need to travel quickly from one point in the network to another cell delay variation cdv is the range of delays experienced by each group of associated cells low cell delay variation means a group of cells must travel through the network without getting too far apart from one another cellular networks utilize various standards for data transmission including 5g which can support one million separate devices per square kilometer requirements of the types of traffic edit the types of traffic found in a broadband network with examples and their respective requirements are summarised in table 1 table 1 network traffic types and their requirements 14 traffic type example required bandwidth cell delay latency constant voice guaranteed circuit emulation minimal low variable compressed video guaranteed variable low available data not guaranteed widely variable variable computer networks edit many computer networks use a simple line code to transmit one type of signal using a medium s full bandwidth using its baseband from zero through the highest frequency needed most versions of the popular ethernet family are given names such as the original 1980s 10base5 to indicate this networks that use cable modems on standard cable television infrastructure are called broadband to indicate the wide range of frequencies that can include multiple data users as well as traditional television channels on the same cable broadband systems usually use a different radio frequency modulated by the data signal for each band 15 the total bandwidth of the medium is larger than the bandwidth of any channel 16 the 10broad36 broadband variant of ethernet was standardized by 1985 but was not commercially successful 17 18 the docsis standard became available to consumers in the late 1990s to provide internet access to cable television residential customers matters were further confused by the fact that the 10pass ts standard for ethernet ratified in 2008 used dsl technology and both cable and dsl modems often have ethernet connectors on them tv and video edit a television antenna may be described as broadband because it is capable of receiving a wide range of channels while e g a low vhf antenna is narrowband since it receives only 1 to 5 channels the u s federal standard fs 1037c defines broadband as a synonym for wideband 19 broadband in analog video distribution is traditionally used to refer to systems such as cable television where the individual channels are modulated on carriers at fixed frequencies 20 in this context baseband is the term s antonym referring to a single channel of analog video typically in composite form with separate baseband audio 21 the act of demodulating converts broadband video to baseband video fiber optic allows the signal to be transmitted farther without being repeated cable companies use a hybrid system using fiber to transmit the signal to neighborhoods and then changes the signal from light to radio frequency to be transmitted over coaxial cable to homes doing so reduces the need for multiple head ends a head end gathers all the information from the local cable networks and movie channels and then feeds the information into the system however broadband video in the context of streaming internet video has come to mean video files that have bit rates high enough to require broadband internet access for viewing broadband video is also sometimes used to describe iptv video on demand 22 alternative technologies edit power lines have also been used for various types of data communication although some systems for remote control are based on narrowband signaling modern high speed systems use broadband signaling to achieve very high data rates one example is the itu t g hn standard which provides a way to create a local area network up to 1 gigabit s which is considered high speed as of 2014 using existing home business and home wiring including power lines but also phone lines and coaxial cables in 2014 researchers at korea advanced institute of science and technology made developments on the creation of ultra shallow broadband optical instruments 23 internet broadband edit main article internet access in the context of internet access the term broadband is used loosely to mean access that is always on and faster than the traditional dial up access 24 25 a range of more precise definitions of speed have been prescribed at times including greater than the primary rate which ranged from about 1 5 to 2 mbit s ccitt in broadband service in 1988 26 internet access that is always on and faster than the traditional dial up access
