  • Multi-stream associative memory architecture for computer telephony
    Patent number: 6393515
    Abstract: Aspects of the present invention are directed to communications circuits and method that utilize associative memories for providing telephony switching of data between different time slots in one or more time division multiplexed (TDM) serial data lines or streams. The communications circuit may include a first content-addressable memory block and a second content-addressable memory block each of which receive the same address for independently generating tags for accessing a data memory to provide data to or receive data from TDM data lines.
    Type: Grant

    Date of Patent: May 21, 2002
    Assignee: NMS Communications Corporation
    Inventors: Jonathan D. Pollack, Charles C. Linton
  • Phase alignment of frames in computer telephony busses
    Patent number: 6219395
    Abstract: A communication bus interface circuit includes a local frame signal generator responsive to a device clock signal and having a local bus frame signal output. A synchronization loss detector is responsive to the local frame signal output and to a bus frame signal input. A clock adjuster is responsive to the synchronization loss detector and to the device clock signal to adjust the local frame signal generator until synchronization between the bus frame signal and the local frame signal is established.
