Abstract: The invention is a diagnostic tool for collaboratively testing a T1 line from remote terminals. A Diagnostic Interface Unit (DIU) containing test and monitoring equipment is connected into a T1 line close to a demarcation point. Testing from that common point, to either end of the T1 line is then performed by one or more operators at remote terminals.

Using the DWS, one of the operators causes the DIU to be switched into the T1 line and the T1 line configured and tested. All operators see the test setup and results on their own screens in real-time, making this remote testing equivalent to the operators meeting at the demarcation point and jointly testing from that point out.

Abstract: A system analyzer may generate an estimated frequency response of a device, system, communication medium, or combination thereof by utilizing a stimulus signal that is robust against IQ modulator impairments. A stimulus generator may be used to generate a plurality of discrete tones according to a frequency spacing and a frequency offset. The frequency spacing and the frequency offset cause spectrally inverted spurs (generated by impairments of the IQ modulator) to occur at frequencies other than frequencies of said modulated signal that are associated with said plurality of discrete tones. Additionally, by implementing a Discrete Fourier Transform (DFT) to possess a frequency resolution equal to the frequency offset, there is no leakage of power associated with the spectrally inverted spurs into frequency bins of the DFT associated with the desired frequency components. Likewise, leakage between the desired frequency components and leakage associated with the local oscillator may be avoided.

Abstract: A system and related method for monitoring the state of health of sensors in an integrated vehicle stability control system. In one embodiment, the system determines whether a yaw rate sensor, a lateral acceleration sensor or a hand-wheel angle sensor has failed. The system uses a plurality of models to generate estimates of the outputs of the sensors based on the actual sensor measurements. Residuals are generated as the difference between the measured value and each of the estimates for the particular sensor. The residuals are compared to a threshold to determine whether a fault flag will be set for each residual. The threshold for the hand-wheel angle sensor is an adaptive threshold because it does not have physical redundancy. If the fault flags for the residuals for each sensor have a particular pattern, then a fault is output for that sensor.

Abstract: In a method for assigning test numbers, current testflow context information is maintained during the execution of a testflow. If one or more test number factors have been specified for one or more levels of the current testflow context, the test number factors are used to determine a base number for a current test number range. Otherwise, the base number is set to a default base number. Upon execution of a subtest in the testflow, a result of the subtest is assigned a next test number in the current test number range. The following items are then associated in a test number database: 1) an identifier of the subtest, 2) the current testflow context information, 3) the test number, and 4) the base number. When stored in the database, the base number serves as a specification number for its corresponding test number. Also disclosed are other methods and apparatus that use contextual test number factors to assign test numbers.

Abstract: Mechanisms for automatically generating code that tests capabilities of a test computing system to simulate a message exchange pattern. The code generation computing system uses a message exchange pattern definition to generate the simulation code. For each state in which the message exchange pattern definition allows valid messages to be transmitted, code is generated for that state that at least simulates the transmission of a valid transmission message. For each state in which the message exchange pattern definition allows valid messages to be received, code is generated for that state that simulates the receipt of a valid receipt message. If the transmission or receipt of the message causes a state transition to occur, code is generated that causes the appropriate state transition in the message exchange pattern.
