Abstract

PURPOSE:To allow an attendant to grasp the holding state of incoming calls, by providing a display means corresponding to meet me answer at an attendant board of a private branch exchange. CONSTITUTION:The active state of a park line of an exchanger main body 1 is detected at a holding detector 11, a status discrimination circuit 12 consisting of flip-flops is set, a driving circuit 13 is operative with the output, display 14 (BLF6) is illuminated, and the park of incoming calls is displayed. A response detector 15 is energized with park detection, a detection mode is set, and a dial signal from a called party telephone set to the park line holding the incoming call at the detector 15 is detected, the status discrimination circuit is reset with this detection and illumination of a display device is stopped. Thus, a display corresponding to the parking of incoming calls and meet me answer to the parking can be made.
