Abstract

PURPOSE:To simplify the operation of a caller, by stopping the callout of a previous called party and calling out other called party, even if the caller calls out the called party. CONSTITUTION:While a caller A first calls out a called party B, a callout tone RBT and a callout signal LR are transmitted with an intra-office trunk IOT. In this case, an outgoing register OR is connected to the caller A. In the register OR, codes A and B of the called party B are stored and the code C is erased. When the caller A dials 3 before the called party B responds, it is stored in a C code memory of the outgoing register OR, the marker connector MC is closed and a marker M is started from the register OR. The vacancy and busy state of the subscriber C is identified with the A, B, C code memories of the register OR by the marker M, if vacant, the callout to the called party B is stopped and the callout to the called party C is started.
