Definitions

  • the present invention relates generally to the provisioning of broadband services and, more particularly, to a method and system for provisioning broadband service to subscribers relatively instantaneously at the subscriber's initiative via telecommunication networks.
  • IP Internet Protocol
  • DSL digital subscriber line
  • ADSL Asymmetrical Digital Subscriber Line
  • ADSL is primarily aimed at the residential market and provides greater bandwidth for downstream data than for upstream data and works by reserving a portion of the available channel bandwidth for support of traditional analog telephone service, also often referred to as Plain Old Telephone Service (POTS).
  • POTS Plain Old Telephone Service
  • Other examples of DSL include High data rate Digital Subscriber Line (HDSL), and Very high data rate Digital Subscriber Line (VDSL), and Symmetric DSL (SDSL) which provide equal bandwidth in both the upstream and downstream directions. SDSL does not provide support for POTS and is better suited to business applications such as network server communications, etc.
  • the central office houses a telephone exchange to which subscriber home and business lines are connected to the network on what is called a local loop.
  • many of the connections to residential and business subscribers are made using copper wires or twisted pairs that collectively form a large copper network operated by the telecom provider.
  • MDF main distribution frame
  • the central office must dispatch technicians to the MDF site to manually perform installations of telephone and other services such as xDSL which are highly labor intensive processes that result in one of the most significant costs faced by telecom providers.
  • FIG. 1 illustrates an exemplary prior art connection of a conventional analog phone connection from the subscriber phone 100 to the central office exchange via the MDF.
  • the subscriber phone 100 and corresponding subscriber line 102 connects to a connector block within the MDF cabinet.
  • the MDF typically comprises columns of connector blocks 110 for the line side that connect to the subscriber lines.
  • columns of connector blocks 112 on the exchange side for which lines from the exchange are connected within the MDF.
  • the lines at the exchange are connected to a plurality of line cards 115 that convert the analog signal to a digital signal such as to PCM, in the case when connected to a digital network.
  • a cross-connection is generally made by physically placing a jumper wire 114 to connect the subscriber line to the exchange, for example, subscriber line 102 to port 1.
  • the exchange is further connected to the public switched telephone network (PSTN) for routing incoming and outgoing calls to and from the subscriber line.
  • PSTN public switched telephone network
  • the connector blocks used in MDFs are basically similar, although there are minor variations that are currently in use, one widely used type is the LSA-Plus connector block manufactured by KRONE Inc., a subsidiary of GenTek Inc. of Hampton, New Hampshire, USA.
  • the KRONE connector blocks are typically able to accommodate up to 2 x 10 line pairs at a time. Thus there can be 10 subscriber line pairs connected to the connector block for connection to the exchange ports 1-10 respectively. Additional subscriber line pairs are cross-connected to the exchange via further connector blocks to further exchange ports.
  • FIG. 2 illustrates an exemplary prior art process for connecting a subscriber line 102 to a central office data network 126 for delivering high-speed xDSL service.
  • the data network can be the Internet, local public or private Intranets, or other types of data networks.
  • the subscriber phone apparatus 100 and computer equipment 101 are connected to a splitter 103 and connected the subscriber line 102.
  • the line is connected to connector block 110 however, instead of connecting a jumper wire directly to the exchange side connector block 112, jumper wire 118 is typically connected to connector block 120, which feeds into a filter device 122 comprising high and low pass filters for separating the low frequency analog phone signals from the high frequency data signals on the subscriber line.
  • the high frequency signal components are supplied to, or received from, one or more so-called digital subscriber loop access multiplexers (DSLAMs).
  • DSLAM contains 'analog front end' (AFE) circuitry that includes amplifying circuitry for processing the high frequency signals by digitizing the high frequency signals from the xDSL lines and supplying the resulting digital data signals to a digital signal processor (DSP) modem 124 for transmission to and from the data network 126.
  • AFE 'analog front end'
  • DSP digital signal processor
  • the low frequency phone signals from the low pass filter is typically routed to a connector block 130 on the line side in order to make a cross-connect back to the connector block 112 for connection to physical exchange port 1 which maintains the original subscriber telephone service and number.
  • the physical port is the same as the logical port in the exchange.
  • the existing jumper wire When installing xDSL to an existing subscriber line, the existing jumper wire needs to be removed and two new jumper wires added, which often makes it is necessary to expand the MDF. This means there are additional requirements for additional connector blocks, jumper wires, floor space, and labor for each new installation.
  • the amalgamation of jumper wires may cause a multiple of signalling problems. For example, the extending wiring adds capacitance and resistance and may pick up considerable electromagnetic interference from external sources such as cross talk from adjacent active pairs. All of these effects can disrupt xDSL broadband digital service and reduce the performance provided to the subscriber.
  • DSL broadband from subscribers therefore equipping the exchange to cover that remote possibility would be prohibitably expensive. Additionally with 100 percent build-out would require increases in physical space in of the MDF that may not be available, not to mention problems with crosstalk from the large amount cabling may cause.
  • Another technique could be to replace only a portion of the line cards with combo cards in anticipation that only a certain percentage will opt for DSL. However, this would not practical since it is not possible to know in advance which lines will be connected.
  • a further complication arises in some situations where telephone companies are required by local competition laws to allow competing broadband service providers to install and operate modem equipment in the telecom network in order to ensure that customers can have a choice of broadband providers.
  • a method and system for provisioning instant broadband service to a subscriber line via a telecommunication network is disclosed.

Abstract

L'invention concerne un procédé et un système permettant de fournir un service à large bande relativement instantanément à une ligne abonné par l'intermédiaire d'un réseau de télécommunications, sur l'initiative de l'abonné. Dans un mode de réalisation, un ordinateur à capacité large bande (101) est connecté au réseau de télécommunications par le branchement d'une prise téléphonique standard dans les locaux de l'abonné. Un détecteur (112) situé dans le central téléphonique détecte la présence de l'ordinateur par la détection des signaux de données haute fréquence sur la ligne provenant du modem, et achemine automatiquement la ligne vers un dispositif filtre afin de séparer les signaux téléphoniques des signaux de données au moyen d'un système d'interconnexion automatisé (400). Les signaux téléphoniques sont acheminés vers le central téléphonique, puis vers le RTPC pour un service téléphonique ordinaire. Les signaux de données sont acheminés vers un ensemble de modems xDSL pour une connexion à un réseau de données haute vitesse (126). Dans un autre mode de réalisation, les signaux téléphoniques sont acheminés vers un nouveau port physique sur le central, qui est reconfiguré par un logiciel dans le central téléphonique afin de représenter le port logique 1 correspondant au port physique original 1, de sorte que l'abonné puisse conserver le niveau antérieur de service et son numéro de téléphone. Une page Web portail permettant à l'abonné de choisir un fournisseur de service à large bande parmi des fournisseurs multiples est affichée automatiquement sur l'ordinateur, de sorte que la ligne soit commutée vers l'équipement modem exploité par le fournisseur de service à large bande choisi dans le central téléphonique.
