Abstract: A method and system for monitoring a packet network by using call detail records (CDRs) are disclosed. The method first receives at least one call detail record (CDR) at a completion of a call from at least one voice gateway router that serviced said call and analyzes said at least one CDR. The method then monitors at least one performance parameter in accordance with said at least one CDR.

Abstract: A method and system for enabling a network service provider to monitor a packet network by using call detail records (CDRs) are disclosed. The method first detects a termination of a call by at least one voice gateway router and generates a call detail record (CDR) at said termination of said call by said at least one voice gateway router. The method then forwards said call detail record by said at least one voice gateway router to at least one CDR collecting and analysis server.

Abstract: A control system for a marine vessel having one or more engines and a transmission associated with each engine is disclosed. The control system includes one or more control stations, each having a control arm and arm position means coupled to the control arm for providing an electrical signal that represents a position of the control arm within its operating range. The system includes one or more electronic control units, each of which is electro-mechanically coupled to an engine and a transmission. A first electronic control unit (ECU) includes input means for receiving the electrical signal, control means for controlling a throttle of a first engine and shift position of a first transmission based on the electrical signal, and output means for providing a control signal that represents a current position of the control arm to a second ECU.

Abstract: A control system for a marine vessel having three or more engines is disclosed. The three or more engines may be operated via one or two control levers from each of one or more control stations. The control system may include a first control lever and a second control lever, each of which has an associated operating range. The control levers operate the engine throttle and transmission controls for three or more engines in a plurality of modes. This may be accomplished under software control using a digital data link between respective engine control units associated with the engines.

Abstract: A method employs call detail records for developing a report on the usage of VoIP calling along a network path or through a network location. By utilizing, for example, a call-beginning record and a call-ending record for each connection, a report is created of the number of concurrent VoIP calls that a specified equipment or network path carries at any given instance by retrieving batches of stored call detail records, culling the records that are relevant to the specified equipment or network path, considering the culled records in a time sorted manner, and incrementing or decrementing a counter based on whether a considered record is a call-beginning record or a call-ending record, respectively. The state of the counter is reported, illustratively, as a line entry each time the counter's state is modified.

Abstract: A system and method make quality measurements in a network to determine if a Service Level Agreement is breached. The system includes a plurality of routers for routing traffic through the network, means for taking measurements on a path between a first router and a second router, and means for charging at least one of the plurality of routers when data related to the measurements falls below a target value.

Abstract: Location of multiple symbols in error is enhanced by using affine polynomial-based apparatus and methods. An algebraic trace function 0 (vector) provides a test for whether or not the location polynomial has roots in the field of interest. The selected roots then combine with previously calculated error-indicating syndromes to indicate symbols in error. Informational states developed for error location are employed to generate error patterns.
