Abstract
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.
