  • Broadband telecommunications system
    Patent number: 7327728
    Abstract: A communication system comprises a signaling processor configured to receive telecommunication signaling for calls, and responsively on a call-by-call basis, select routing information based on the telecommunication signaling and transfer control messages indicating the routing information. The communication system comprises a communication unit configured to receive the control messages and user communications for the calls, and responsively on the call-by-call basis, convert the user communications from a first communication format into a second communication format having headers that include the routing information selected by the signaling processor and transfer the user communications in the second communication format.

  • ATM direct access line system
    Patent number: 6421344
    Abstract: The invention is an ATM system to route DS0 traffic from T1 Extended Superframe (ESF)or Superframe (SF) systems that use robbed bit signaling. The invention is able to route the call selecting the ATM VPI/VCI that routes the call within the ATM system. DS0s with robbed bit signaling are transported transparently by the ATM system.

  • Cell processing for voice transmission
    Patent number: 5606553
    Abstract: The present invention is a method and system which can be applied to supply a constant bit rate link with digital information from a packet or cell based link, such as an Asynchronous Transfer Mode (ATM) link. The present invention automatically provides compensation information to a buffer supplying the constant bit rate link with information. The compensation is not used if packets or cells are made available in the buffer.
