Communication system architecture and operating methodology providing a virtual neighborhood network
Patent number: 7142503Abstract: A communication system (10) supports the provision of a plurality of dedicated communication resources (50–64), such as copper drops, RF links and optical fibers, to dedicated home-gateway devices (44–48) or distribution points (124). The communication resources (50–64) support broadband interconnection (104) between the dedicated home-gateway devices (44–48) or distribution points (124) and an access multiplexor (30) in a network (12). Each gateway device (44–48) or distribution point (124) generally includes a local RF transceiver (84) and associated control logic (80–82) that allows local communication (86) between gateway devices (44–48) and hence statistically multiplexed access (60–64, 89) to multiple communication resources, thereby providing increased bandwidth in uplink and/or downlink directions.Type: GrantFiled: February 11, 2000Date of Patent: November 28, 2006Assignee: Nortel Networks LimitedInventors: Michael F Grant, Igor K Czajkowski, Brian M Unitt -
Patent number: 7012922Abstract: A digital subscriber line (DSL) arrangement provides data and voice over IP (VoIP) services over a subscriber loop. Instead of conventional multiplexing at the IP layer, two separate IP packet streams are provided, one stream carrying delay insensitive data traffic and the other transporting delay sensitive traffic, in particular, packetised voice. The system segments each IP stream (i.e. those carrying voice and data) separately to produce two ATM streams which are then multiplexed using an ATM multiplexer. This reduces the delays to voice traffic resulting from queuing behind long data packets.Type: GrantFiled: August 17, 1999Date of Patent: March 14, 2006Assignee: Nortel Networks LimitedInventors: Brian M Unitt, Michael F Grant

Patent number: 6643059Abstract: An optical array amplifier has a first light beam shaper, a first waveguide to guide an input optical signal consisting of a plurality of wavelengths to the first beam shaper, a diffracter illuminated by light from the first beam shaper to diffract the optical signal into individual wavelengths or groups of wavelengths, a second waveguide connected to a source of optical pump energy, a second beam shaper combining optical pump energy from the second waveguide with the diffracted signal wavelengths or groups of wavelengths without the pump energy impinging on the diffracter, so that a proportion of the optical pump energy is mixed with each of the wavelengths or groups of wavelengths, and to focus the mixed optical signals onto a third waveguide connected to an optical amplifier utilizing the pump energy to cause amplification of the individual wavelengths or groups of wavelengths mixed with the corresponding proportion of pump energy. The amplifier may be implemented as a planar waveguide device.Type: GrantFiled: November 2, 2001Date of Patent: November 4, 2003Assignee: Nortel Networks LimitedInventors: Michael F Grant, Robert Spagnoletti, Stephen Day

Publication number: 20020176558Abstract: A modem (34, 40) at a customer premises (14, 38) and a switch at an exchange (12, 50) are modified to allow a data session (102, 202) supported on a dedicated wireline communication resource (16) to be optionally terminated (110), but preferably suspended (114, 218), upon detection of a subsequently placed voice call (104, 204) on the dedicated wireline communication resource (16). Before termination of a data session, a user either selects a termination option or is provided with an in-call option to terminate the data session, with the voice call then switched (122) to the dedicated wireline communication resource (16). The data session is therefore cleared down rather than lost through connection corruption. Alternatively, the modem (34, 40) and the exchange (50) interact to silence modem transmissions therebetween, whilst retaining a data connection (20) between the exchange (12, 50) and an end-point data service provider (ISP, 18).Type: ApplicationFiled: December 22, 2000Publication date: November 28, 2002Inventors: Christopher Tate, Michael F. Grant

Publication number: 20020080444Abstract: A communications access network comprising a combination of fibre and co-axial cable to the home having co-axial cable deployed in the home comprises a head end, to which outstations are coupled via an optical fibre medium incorporating a star coupler or splitter. The head end is arranged to transmit downstream to the outstations a sequence of frames comprising data frames and command frames. The command frames comprise first and second frames and provide marshalling control of upstream transmissions from the outstations. The first command frame incorporates a global command to all outstations to pause upstream transmission for a pre-set time period. The second command frame is transmitted within the pre-set period and incorporates a further pause command having an associated zero time period and addressed to a selected outstation overriding said global command thus allowing that one selected outstation to transmit to the head end.Type: ApplicationFiled: December 22, 2000Publication date: June 27, 2002Inventors: David Phillips, Michael F. Grant, Frank E. Lockwood

Patent number: 6272209Abstract: A method, apparatus, and software for providing lifeline service during power failure affecting Customer Premises Equipment (CPE) in a Digital Subscriber Loop (DSL) arranged to carry voice traffic in band rather than on a separate analogue POTS band. The arrangement provides a reduced service, capable of supporting at least one voice call, to operate during such power failure and, where a single call is in progress during power failure, that call may be maintained during the transition from DSL to analogue POTS lifeline service. Where a call is in progress upon power restoration, the lifeline POTS service may be maintained until completion of the call so as not to interrupt a potential lifeline call.Type: GrantFiled: August 16, 1999Date of Patent: August 7, 2001Assignee: Nortel Networks LimitedInventors: Mark Bridger, Michael F Grant, Roger J Williamson, Christopher Tate, Andrew D Wallace, Jeffrey Farrington
