摘要： An alien cross-talk method involves a victim cable and one or more disturber cables. The method encompasses a transmission of a RF test signal on each disturber cable between an alien cross-talk test signal unit connected to one end of a disturber cable and another alien cross-talk test signal unit connected to the other end of the disturber cable. The method further involves a measurement of an alien cross-talk signal generated on the victim cable in response to each cross-talk coupling of the victim cable and the disturber cable(s) based on the transmission of the RF test signal(s) on the disturber cable(s). The RF test signal(s) can be in the form of a RF frequency sweep and the measurement of the alien cross-talk signal can involve an execution of a RF frequency measurement sweep for acquiring samples of the alien cross-talk signal generated on the victim cable.

摘要： A continuous bi-directional file-play-record voice and video quality tester system (“CFPR-VVQT”) for measuring the quality of voice or video communication links from a customer premises equipment (“CPE”) through a Network under Test to a voice and video quality tester (“VVQT”). The start and end of a set of quality testing sample signals are determined by a start flag signal and an end flag signal, respectively, generated by the CFPR-VVQT. The flag signals may be triple tone modulation frequency (“TTMF”) tones. The CFPR-VVQT will measure the quality testing sample signals, determine a signal quality test result, and then transmit the test results back through Network under Test to the originating VVQT.
