PURPOSE:To clearly show the position of a trunk line key and remove cumber of operation for the operator by providing the operational procedures to perform operation as to the trunk line by refering to the trunk line key-station line coordinate memory table. CONSTITUTION:A CPU121 executes operation in operational data mode when a switch 105 is on, but does one in call processing mode when the switch 105 is off. In the operational data set mode, when the data from the number of the trunk line usable for a key telephone 101 is inputted, the CPU121 generates the usable-station-line memory table, and functions as a memory-table-generating procedure to generate the trunk line key/station line coordinate memory table which coordinates the two parameters by arranging the numbers of the usable trunk lines in the order from the smallest to the larger. In the processing mode, as to the trunk line-related processing, the CPU121 functions as a processing mean that performs as refering to the trunk line key-station line coordinate memory table. |
