  • Efficient transport of TDM services over packet networks
    Patent number: 7961755
    Abstract: A method for data communications includes receiving a time-division-multiplexed (TDM) input signal carrying a payload comprising data and determining whether the data comprise synchronous or non-synchronous data. A first encapsulation scheme is selected if the data comprise synchronous data, and a second encapsulation scheme is selected if the data comprise non-synchronous data. The data are encapsulated for transmission over a packet-switched network in accordance with the selected encapsulation scheme.
    Type: Grant
    Filed: March 16, 2009
    Date of Patent: June 14, 2011
    Assignee: Corrigent Systems Ltd.
    Inventors: Rafi Harel, David Zelig, Leon Bruckman, Nitzan Kappel

  • SONET circuit emulation with VT compression
    Patent number: 7133415
    Abstract: A method for data communications includes receiving a time-division-multiplexed (TDM) input signal on a first circuit, the signal including an input sequence of frames of data, each such frame divided into sections for carrying respective sub-rate payloads. After determining which of the sections are active, such that the data in the sub-rate payloads of the active sections include user data, and which of the sections are inactive, the user data in the active sections are encapsulated into data packets for transmission over a packet network, while omitting from the packets at least some of the data from the inactive sections.
