Abstract

When input signals from a plurality of input ports are selected and are inserted into the time slots to be output from a single output port and to insert respective signal data into time slots in synchronization with a synchronizing signal, the apparatus is so constructed that selector units (5-i) are provided to correspond to input ports (1-i), and a synchronizing signal generating unit (4) is provided to output, synchronously, a synchronizing signal and selecting signal information for designating a selector unit (5-i); the selector unit (5-i) being provided with a determining unit (6) for determining whether or not the selecting signal information designates the selector.
