摘要： A plural channel amplitude modulated telephone carrier system having a plurality of transmitters to provide for the transmission of a like plurality of frequency division multiplexed, amplitude modulated carrier signals in a common direction along a transmission line to a remote termination of the transmission line, and an automatic carrier level coordination control circuit having a first circuit means for developing a d.c. control signal that varies as a predetermined function of the transmission line length, and a second circuit means connected to the first circuit means for controlling the transmit power of each of the aforesaid carrier signals as a function of its own carrier frequency and as a function of the d.c. control signal. The telephone carrier system may be of the station carrier type and may have two or more plural channel amplitude modulated carrier sub-systems, each having its own transmission line. The automatic carrier level coordination control circuit is designed to be common to two or more of the carrier sub-systems.

摘要： A device for testing data communications cabling. The device consists of a signal generator that can generate a test signal to test the data communications cabling and a receiving component that can receive a reflected signal produced by reflection of the test signal from the data communications cabling including any reactive point source disturbance that may exist on the cabling. The receiving component can determine characteristics of the reflected signal by analyzing the phase rotation and amplitude of the reflected signal. The device can also include a cancellation generator that can generate a cancellation function based on the characteristics of the reflected signal. The cancellation function can substantially negate a portion of the reflected signal.
