PURPOSE:To inform the delay in the response to the operator, by monitoring a waiting time of all calls to a waiting congesting call to a cordless attendant board and displaying calls kept waiting for a predetermined time or over by means of incoming call lamp. CONSTITUTION:A central controller (CC) 6 reads a memory of a trunk control section (TKC) 4 to flicker an incoming lamp of an attendant board (ATT) 9 and the present time is stored to a storage device (MM) 8 via a memory control section (MC) 7. Further, the content of the MM 8 is read out from the CC 6 via the MC 7 to obtain difference with the present time, and when the value is larger than a prescribed value, the flickering method of an incoming lamp is changed to urge the response of the attendant board to the operator. |
