Circuit-switched network

A circuit-switched network, in an STM (Synchronous Transfer Mode) network comprising:

• a plurality of local switches each serving at least one terminal, and
• at least one transit switch connected between said plurality of local switches;
• wherein logical addresses for sending and receiving burst data between the terminals of said plurality of local switches are allocated to at least some of the terminals;
• and
• each of said local switches comprises:
• a receiver configured to receive said burst data which has been given a logical address and which arrives from said at least one terminal served by that said local switch;
• a first device configured to manage the logical addresses of each of the at least one terminal served by that said local switch;
• a second device configured to acquire time slot information which has been allocated with respect to said STM network to the local switch which serves the at least one terminal forming a destination of said burst data, the allocated time set information having been carried out in accordance with the logical address of said received burst data;
• and
• a third device configured to transfer the burst data through the STM network in accordance with the time slot information obtained by said second device.
