Abstract

PURPOSE:To eliminate the lowering of the process capacity caused by the multi- link exchange, by securing the double action for the key which designates the manual board channel. CONSTITUTION:Manual board ASC1 is connected to the terminal side including channel designation contact t2 of manual board ASC0 with no use of board trunk BDT1. Both contacts t1 and t2 within ASC0 function simultaneously, and the talking becomes possible among subscribers A and B plus ASC0 and ASC1 each by contacts t1 and t2 plus the internal connection of board trunk BDT0. In the case of transfer, the connection of trunk BDT0 of ASC0 is changed as shown by the dotted line and via the operation of ASC0. Thus the lowering of the process capacity caused by the link exchange can be avoided.
