摘要： Presented are method and apparatus embodiments to terminate an interruptible signal path when the interruptible signal path is unterminated. The apparatus can comprise a signal path from a supplier-side port thru a user-side port, a signal source arranged to provide a signal to the conductor; and a signal circuit arranged in the interruptible signal path. The apparatus can determine when the signal path is unterminated and, in that case, interrupt and terminate the signal path by putting a signal switching device in the appropriate state and/or sending signals from the signal path to a prescribed signal level connection point. When a user device is not connected or connected improperly, or the signals through the signal path are otherwise unterminated, the interruptible signal path can be interrupted and terminated. The method and apparatus embodiments can be used in various combinations with multiple signal paths having multiple signal branches.

摘要： A downstream bandwidth conditioning device includes a forward path. A coupler is connected within the forward path providing a secondary path. A tuner connected to the coupler is tunable based on an input from a microprocessor. The tuner provides a tuner output of a selected channel, the selected channel being at least one high frequency channel and one low frequency channel. A channel analyzer connected to an output of the tuner provides the microprocessor with a modulation output that differs when the selected channel is an analog modulation versus a digital modulation. A slope adjustment circuit connected within the forward path between the coupler and the supplier side connector is adjustable based on an slope control output provided by the microprocessor. An output compensation circuit connected within the forward signal path between the coupler and the supplier side connector is adjustable based on a level control output from the microprocessor.
