A central processing unit performs the functions designated by the multi-number plan in response to an input from the dial keys of one of the general telephone set and the key telephone set. The central processing unit check an extension circuit to determine when a receiver of one of the subscriber extensions has been lifted, and when a receiver of one of said subscriber extensions has been lifted, determines whether the subscriber extension having the lifted receiver utilizes a first number plan or a second number plan by searching a number plan designation table for a position of the subscriber extension having the lifted receiver. The first number plan is assigned to those subscriber extensions having a key telephone set, and the second number plan is assigned to those extension subscribers having a general telephone set. The central processing unit determines whether an input from a dial key of the subscriber extension having the lifted receiver corresponds to a number stored in a table corresponding to one of a first number plan and a second number plan, and performs a function corresponding to the dial key when the input from the dial key corresponds to the number stored in the table corresponding to one of the first number plan and the second number plan.
