Abstract

PURPOSE:To simplify the operation of substitutional response, by providing an area, where a substitutional response class is registered, in a storage device and by discriminating the substitutional response class by the hook-off operation of the handset for an incoming to the other extension in the same group. CONSTITUTION:When the number of an extension A2 is dialed from an extension B, a route (a) is connected, and the ringing tone is transmitted to the extension B from an intra-office trunk IOT, and the call signal is transmitted to the extenstion A2 from a rining trunk RGT. If an extension A1 in the same group as the extension A2 hooks off the handset at this time, a subscriber's line scanning device LSCN detects the originating of the extension A1 and reports it to a central control device CC. The device CC discriminates that the extension A1 is in the substitutional response class on a basis of extension data of the extension registeed in a main storage device MM, and the device CC checks extensions of incoming in the same group and drives a switch driving device SC to connect a bus (b), and thus, substitutional response is possible.
