Abstract

PURPOSE:To lighten a burden on the operation of a switch box operator by providing the incoming processing part of a switchboard with a camp-on registering function of switch box and by performing switch box camp-on registration of an extension telephone set automatically when the extension telephone set is busy. CONSTITUTION:When switch box operator ATT dials the number of extension telephone set A, central controller CC receives the incoming extension number and finds the equipment position of the incoming subscriber in memory device MEM to check the state of telephone set A in subscriber coordinate memory LM. Controller CC, when judging that telephone set A is busy and of the allowable class of a connection to a main wire, registers a switch box camp-on regarding telephone set A and while the control is transferred to camp-on subscriber supervisory part SUP, lamp driver LD places an extension state display lamp in the camp-on flashing state. As supervisory part SUP detects telephone set A being released and free, controller CC places telephone set A in the calling state and changes the extension state display lamp into the flashing state showing that calling is in process via device LD.
