Abstract
In a combined telephone and electric power distribution system, both telephone signals and electric power are distributed by way of a common distribution system wherein signal conducting means (such as optical fibers) and electric power conducting means are routed alongside each other to/from various utilization points, such as to/from a telephone instrument, a computer, an electric lighting fixture and/or a power receptacle. At some of these utilization points, telephone signal receptacles are provided alongside electric power receptacles. At other points, the signal conducting means is terminated in a radio transceiver and wireless signal radiation/receiving means. In a typical situation, such a transceiver has its antenna mounted at or near a ceiling lighting fixture; which radio antenna interacts with some other transceiver combined with a telephone and/or other information-handling apparatus located nearby. In addition to being used for transmitting telephone and/or other information signals, the signal conducting means is used for controlling the flow and/or usage of electric power, such as control of light from individual lighting fixtures, for distributed protection against electrical circuit overload and/or fire hazards. Also included is a provision for supplying uninterruptible power to selected utilization points.

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.
