OWN ROUTING SPEECH PATH FOR COPY

摘要

PURPOSE:To attain connecting a copied cell to an assigned output terminal and to reduce the memory quantity of a routing information giving circuit by keeping the throughput of a copy switch to high level. CONSTITUTION:A self routing function is provided to a copy switch so that a copied cell may be connected to a fixed output terminal, the minumim number and the maximum number of the output terminal are given as copy information and plural sub-switches are inserted into among respective speech path stages to prevent throughput lowering owing to link competition. Accordingly, even when the link competition of the copy cells and link faults are generated, transferring the cell to the switch element of the next stage is attained by taking an alternate route to the sub-switch and the throughput of the copy switch is improved. At the same time, the small memory quantities of routing information giving circuits 201-0 to 201-7 are satisfied.
