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.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
