<p>PROBLEM TO BE SOLVED: To prevent switch efficiency from being deteriorated in the case of extending a switch capacity and to eliminate the need for an additional device for extension. SOLUTION: An input interface section 1-111 has a demultiplexer section 1-411 that demultiplexes an input signal at a speed V into m-sets of signals and an input side selection circuit 1-511 that selects (m-1) sets of signals at a speed V/m from the demultiplexer circuit 1-411 and (m-1) sets of signals at a speed V/m from other packet switch system. Furthermore, an output interface section 1-211 has an output side selection circuit 1-611 that selects (m-1) sets of signals at a speed V/m from a switch module 1-31 and (m-1) sets of signals at a speed V/m from other packet switch system and a multiplexer circuit 1-711 that multiplexes a signal from the switch module 1-31 on the (m-1) sets of signals at a speed V/m from the output side selection circuit 1-611 to convert them into a signal at a sped V. In the case of connecting p-sets of packet switch systems 1-1, m-sets of signals given to the switch module 1-31 are handled by map-sets of signals as one set.</p> |
