  • System and method for testing signals within digital-network packets
    Patent number: 7447158
    Abstract: A system and method for testing signals in digital-network packets includes generation of reference clips and associated reference key values and comparison of the reference key values with current key values associated with incoming current-digital-network packets under test In this way the incoming current-digital-network packets can be tested for either a correct audio and/or video signal or a signal with sufficiently high signal integrity to allow it to be understood by a user at a destination point.

  • Multi-interface telephony test system using separate interface cards
    Patent number: 7068756
    Abstract: The present invention provides a method to configure the hardware and software resources in a system to utilize two physical interface boards in pairs such that their aggregate units of voice processing DSP resources can be applied to either all of a T1 board's physical interfaces or all of an E1 board's physical interfaces. This allows a single telecommunications system to run as either T1 or E1 with no additional hardware required. The present invention also provides the ability to run protocols normally associated with T1 physical interfaces on a card with only E1 physical interfaces. A method for changing the configuration from T1 to E1 and from E1 to T1 is provided as well. Additionally, the method includes configuring the system to look like a single set of contiguous T1 or E1 channels.

  • Analyzing an extended finite state machine system model
    Patent number: 6853963
    Abstract: A method of using a computer to analyze an extended finite state machine model of a system includes providing a graphical user interface that presents a table of rows, receiving data in at least one table row, and determining at least one path through the states and transitions of the extended finite state machine model using at least one of the rows in the table.

  • Computer integration network for channeling customer orders through a centralized computer to various suppliers
    Patent number: 5694551
    Abstract: An electronic requisitioning system for channeling customer requisition orders to internal suppliers and outside vendors, and processing invoices using a centralized computer system. A customer accesses an electronic item catalog and requisition form to place an order transmitted to the central computer system. Requisitions are segregated by supplier and sent as purchase orders to appropriate internal suppliers and outside vendors that ship the items directly to the customer. Invoices are centrally processed and the customer receives a combined invoice for all items requisitions and may transmit payment back through to the central computer system.
