摘要： A combination of algorithms and circuits are used to combine POTS, high-speed bi-directional data, and back-powering onto the drop connection for fiber to the distribution point architectures. A telephone adapter device can be utilized to prevent damage from back-powering occurring at POTS telephones connected to the drop connection. In addition, circuits are used to prevent damage from back-powering occurring at POTS telephones directly connected to the drop connection. A circuit is used to provide more consistent power to the electronics at the distribution point even when the input back-power to the distribution point may fluctuate.

摘要： A testing apparatus and a testing method for a telephone apparatus are disclosed. The testing apparatus includes an audio generator, an audio signal processor, and a noise analyzer. The audio generator transmits a testing audio signal to a receiver of the telephone apparatus. The audio signal processor receives the testing audio signal and an output audio signal. The audio signal processor performs a time-to-frequency transformation operation on a difference between the testing audio signal and the output audio signal to obtain a noise information. The noise analyzer receives the noise information and obtains a maximum noise component among a plurality of noise components respectively corresponding to frequencies in the noise information. The noise analyzer compares the maximum noise component with a predetermined threshold to generate a testing result of the telephone apparatus.

摘要： This is a method for use in a teleconference that troubleshoots echo problems. After receiving a code to begin the troubleshooting process, all legs of the teleconference are muted except a test leg. That test leg is evaluated for echo. The process is repeated for each of the legs of the teleconference. After automatically measuring echo on all legs, results are reported to a moderator or host, who can take action such as muting all legs with echo, or discussing remedial action with each participant on a leg with echo.

摘要： A method for the performance testing of an echo canceller including the steps of transmitting a test signal to the echo canceller, recording an echo energy signal output from the echo canceller as a result of the test signal, measuring the energy and duration of the echo energy signal and calculating a performance score for the echo canceller based on the measured energy and duration of the echo energy signal, wherein the test signal transmitted to the echo canceller has a plurality of discrete frequency band segments of white noise representing sub-bands of an overall bandwidth ranging from about 0 kHz to about 3.5 kHz. The test signal preferably has four discrete frequency band segments of white noise, wherein each discrete frequency band segment of the test signal is repeated in succession, whereby the test signal has a total of eight segments. Thus, the test signal can have a first frequency band segment having a bandwidth of about 0 kHz to about 1 kHz, a second frequency band segment having a bandwidth of about 1 kHz to about 2 kHz, a third frequency band segment having a bandwidth of about 2 kHz to about 3 kHz and a fourth frequency band segment having a bandwidth of about 3 kHz to about 3.5 kHz.
