ABSTRACT:
In a key telephone system, function assignments are made for assignable-function keys by assigning to each key telephone set one of a number of previously-stored patterns of function assignments. Patterns are stored in a memory of the main unit of the key telephone system. Assignment of functions is thereby done more easily, and efficiency of office line use may be improved.
