  • Patent number: 8638906
    Abstract: Voice user interfaces can be tested using test scripts generated by traversing a graph using a recursive search technique, such as recursive depth first search. Test data to accompany the test scripts can be generated by treating conditions in states of the interface as business rules, and fully exercising each state during traversal of the graph. Actual testing can be performed in a faster than real time manner by providing simulated input from test scripts, as opposed to requiring actual input from human testers. The interfaces can also be tested using a gatekeeper intermediary which provides for easy transitions between testing and deployment.

  • Patent number: 8019049
    Abstract: A method for generating reliability tests for a telephone system is based upon sampling an orthogonal array which covers various combinations of test parameters. Field data is collected of actual telephone activity on a telephone system. The field data is evaluated so as to determine call-mix characteristics. Probabilistic weights for the different call-mix characteristics are obtained, and then the probabilistic weights are used to sample the test case scenarios generated in the orthogonal array which have the same call-mix characteristics. These test case scenarios are used to run tests on the telephone system. These tests are preferably performed using automated test scripts. After the test data is collected, reliability metrics are calculated from the test data.

The system can set various signal parameters to any prescribed value. These parameters include carrier frequency error, bit rate error, rise and fall times, amplitude ripple and roll off, modulation depth, nonlinearities, burst duration, burst start time and burst interval. Signal interference can be added to the signal including tones, other signals, noise and other signals of the same as the test radio. Similarly other communications equipment can be tested by the combination of receiving and demodulating a transmitted and regenerating the signal with the same symbols with specified signal parameters.

  • Patent number: 7298827
    Abstract: An invention is provided for testing a quality of communication data received from a SUT. The invention includes storing reference test data comprising a plurality of data segments, and receiving degraded test data also comprising a plurality of data segments, from the SUT. The data segments are located in the degraded test data, and data segments in the degraded test data are matched to related data segments in the reference test data. Further, the data segments in the degraded test data are compared to corresponding data segments in the reference test data using a fixed point operation. In one aspect, the degraded test data can be normalized prior to locating the data segments, for example, utilizing a fixed point Fourier transform. Also, a receive filter can be applied to the normalized test data utilizing a fixed point operation.

  • Patent number: 7149285
    Abstract: A multi-unit test system performs automated and dynamically alterable, double-ended testing of telephone lines, whose service is provided on copper cable pairs. A prescribed set of (e.g., twelve) individual tests are executed either from a hand-held measurement unit, or by a central office-resident direct access test unit, or by a collaboration of the two. The hand-held measurement unit and the direct access test unit exchange FSK-based test control messages with one another that are effective to cause a selected electrical condition to be applied to a first portion of the wireline and to cause a prescribed electrical measurement to be made at a second portion of the wireline.
