OPERATING DATA REWRITE SYSTEM IN KEY TELEPHONE SET

摘要

PURPOSE:To attain the rewrite of the operating data in an operating data memory when a personnel setting the operating data desires by allowing a control means to transfer the corresponding data to a working memory when an input is detected by the 1st detecting means and transferring the operating data in a buffer memory to the operating data memory when the input is detected by the 2nd detecting means. CONSTITUTION:Suppose that the operating data are stored one after another to the buffer memory 101. When an incoming call comes to the 1st trunk line in this case, a control means 105 references a memory table incoming to the station in the operating data memory 11 so as to ring a bell of the 10th, 12nd and 65th key telephone sets. The 1st detecting means 103 analyzes and detects that the input is an input for the operation required to reference plural number of times the identical data in this case and outputs a signal representing the referencing to the control means 105. Then the control means 105 transfers the corresponding operating data from the operating data memory 11 to a working memory 102.
