Abstract
A telephone communication system for communicating between a plurality of exterior telephone lines and a single common in-house two wire line is comprised of a control unit for coupling to the plurality of exterior telephone lines and for controlling communication between the plurality of telephone lines and the common two wire line. A plurality of station units are coupled remotely throughout the building to the common two wire line. The control unit communicates on the digital channel with the plurality of station units in a time frame subdivided into a plurality of time slots. A specified portion of each time slot is reserved for control communication between the control unit and each one of the plurality of station units. A synchronization signal is transmitted for phase locking all the station units to the control unit clock and a common frame synchronization signal is used to align all units in time. Each remote telephone or adapter box has a unique number assigned to it by the setting of a manual switch. Each number corresponds to a slot in a time frame. Thereafter all control signaling to a specific station unit occurs in a particular time slot.

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.
