Abstract

PURPOSE:To make it possible to execute dispatching for a prescribed line from an arbitrary line and simplify the unit and improve service, by providing a dispatching trunk correspondingly to a prescribed line group which receives dispatching. CONSTITUTION:Respective lines of telephone sets T0-Tn which receive dispatching are stored in telephone exchange NW through dispatching unit DSPU, and dispatching trunk DSPT is provided correspondingly to the line group. Then, an arbitrary line is connected to the incoming side of DSPT through NW by specific number dial corresponding to trunk DSPT from the arbitrary line, and respective units DSPU in the line group switch respective lines to multiple-connect them to the outgoing side of DSPT by the control of DSPT. After that, respective lines are called, and dispatching service is performed for the line, which responds to this call, from the arbitrary line through DSPT.
