ABSTRACT:
A small program controlled communication system is disclosed having user changeable feature and line selection control. Associated with each station is a set of switches which are used to associate the various central office lines with the available nonlocking station pickup keys. The user, by setting the switches, can establish any line as a prime line and may select which other lines appear at the station. The setting of the switches also controls various other features available to the station, such as common audible, and privacy. The system is arranged such that the processor interrogates the switches periodically and translates the setting of the switches, which are human factors coded, into machine control codes which are stored in the main memory.
