  • Network service provider architecture in communications network
    Patent number: 7649883
    Abstract: An improved architecture in a circuit switched communications network is provided in which a plurality of network service provider devices, eg intelligent peripherals are arranged to provide network service data to a plurality of time division multiplex circuits and trunks by converting these circuits and trunks to streams of packets, and providing network service data packetized in a set of network service data packet streams to the circuit packet streams without incurring delays to the circuit packet streams. The circuit packet streams may be duplicated and forwarded to the network service provider devices without incurring delay to the ongoing through put packetized circuits, and similarly packet streams containing network service data may be superimposed into the circuit packet streams, without the requirement for the circuit packet streams to be switched to the network service provider devices.
    Type: Grant

    Date of Patent: January 19, 2010
    Assignee: Nortel Networks Limited
    Inventors: Martin Sproat, Bruce Leigh Townsend, Julian Frank Barry Cable, Simon Daniel Breuckheimer, Stephen Rylant Evans, Stephen L Fagg, Michael Flynn Thomas, David John Stacey
