Abstract :
Selective operation of party-line digital communications circuits is discussed, and a requirement for selective control to be divorced from teleprinters is developed. A solid-state (transistorized) selector, which is capable of operating with any class of equipment and is not dependent on teleprinters for its operation, is described in detail. This selector is capable of operating at speeds up to 10,000 words per minute, and is flexible with regard to code format and control arrangement. It has wide application in various types of service.
