Abstract

PURPOSE:To realize the connection to a missing person from a calling side without the elimination of the need for the movement connected directly with an exchanger, by calling out a terminal which seems to be in the nearest location to a missing person directly from the calling side. CONSTITUTION:An exchanger EX is provided with a device corresponding a specific dial to a specific frequency and the frequency to be discriminated is determined with the specific dial transmitted from the calling side. When specific frequency information within a cover zone of each station transmitted from each station is coincident with a determined frequency, the station and the calling side are connected. Further, a telephone set receiving the frequency transmitted from a small sized transmitter is provided with one cover zone.
