摘要：PURPOSE:To form a large-capacity switch even when a memory element whose operation speed is limited is used by arranging plural time switches and selecting circuits, performing parallel and repeated writing to the time switches and independent reading, and selecting desired channel information by the selecting circuits. CONSTITUTION:A series type highway which is an input secondary highway 39 is connected to (m) internal highways 40 in parallel by a series-parallel converting circuit 36 and further connected to (m) time switches 31-1-31-m repeatedly. Information of a subchannel 1 is written in a channel memory 31-l-1-1, information of a subchannel 2 is written in a channel memory 31-l-1-2, and information of a subchannel (k) is written in a (k)th channel memory 31-l-1-k.
A parallel-series converting circuit 37 converts highways from (m) selecting circuits into a series type highway 44 again. Therefore, a switch which has (m)-fold capacity as compared with a conventional constituting method can be constituted when memories having the same speed are used.
