B-1 Alarm and Control System for Remote Control of Coaxial Cable Stations

The B-1 alarm and control system provides means of supervising and controlling as many as ten remote stations in a maximum of four directions from the control station. The maximum distance between the most distant stations in a maintenance group is 1,650 miles which certainly exceeds the range in which remote stations can be serviced efficiently from a single maintenance center. The system presages increasing use of automatically-obtained information about isolated stations and stepped-up use of remote control signals for the telephone plant. As the communication circuits in use increase in complexity, and the trend toward centralized maintenance effort continues, reliable alarm system such as the B-1 alarm and control system will be necessary for efficient use of the new developments.
