ABSTRACT:
Structure for and method of automatically testing an electrical transmission powerline carrier channel on a programmable basis electronically from any end of a multi-ended powerline, including an electronic control unit located at each end of the powerline for transmitting a signal over the channel for a predetermined time, and receiving signals back from the control units of the other ends of the powerline for predetermined times and determining the condition of the powerline carrier channel based on the length of time transmission is received at the end of the powerline where the transmission was initiated. Supervisory testing, resetting and test-inhibiting from a remote location as well as manual initiation of tests at a test unit remote location are also provided. A remote master test structure and method tests the electronic circuit through which a test was initiated. Power may be selectively transmitted over the carrier channel sequentially or concurrently at full and partial power under control of the control units.
