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 frequency band selection device that can be inserted into a signal transmission line of a CATV system on the premise of a user includes at least two signal path sets between a tap side and a premise side. Each signal path set includes two discrete signal paths, a high frequency signal path for a downstream bandwidth and a low frequency signal path for an upstream bandwidth. The high frequency signal path and the low frequency signal path are separated by a cut-off transition frequency that is different for each signal path set. The device further includes a switch controller having at least two discrete switch positions. The switch controller chooses one of the switch positions as a result of an information signal. Each of the switch positions corresponds to a respective one of the signal path sets.

摘要： A downstream bandwidth output level and/or output level tilt compensation device that can be inserted into a signal transmission line of a CATV system on a premise of a user. The device includes a tuner that identifies low and high band signal channels, and a channel analyzer that determines a format of each of those channels. A signal measurement measures low and high band signal strengths. An offset circuit adds or subtracts an offset value to the low and/or high band channel signal strengths depending on whether the respective channel is analog or digital. A microprocessor compares the low and high band signal strengths, including any offset values, to a predetermined signal strength loss curve. A variable output level compensation device and a variable slope adjusting circuit are provided to amplify and adjust the gain slope of the downstream bandwidth.

摘要： An upstream bandwidth conditioning premise device for use as part of a CATV system and for placement on or near a user's premise to reduce noise created on the user's premise that would otherwise be injected into upstream transmission channels and passed into an RF main signal distribution system of the CATV system. The device includes a variable attenuation device, a signal measurement circuit, a memory circuit and an electronic circuit, which is configured to iteratively determine (i) whether an incremental amount of additional attenuation is to be applied and (ii) whether at least a portion of a previously applied incremental amount of attenuation is to be removed. The electronic circuit includes a counting circuit, a threshold comparison circuit configured to compare a peak signal strength to a predetermined threshold, and a peak comparison circuit configured to compare a contemporary peak signal strength to a previous peak signal strength.
