Abstract
A key telephone system having user-friendly electronic directory function in which dialling numbers more than the number of abbreviated dialling numbers can be registered and the number of digits of abbreviated dialling number is maintained to a small number by treating separately an abbreviated dialling data and other directory data upon registration of data. Further, the content of a retrieved directory data can be registered as an abbreviated dialling number. In the system, a necessary number of data can be registered in the directory, and calling operation using an abbreviated dialling number can be made with a fixed number of digits of abbreviated dialling number regardless of the number of abbreviated dialling numbers. Further, registration of abbreviated dialling number can be performed effectively.
