Abstract

PURPOSE:To shorten the time of call setting by lightening a control load on an exchange by providing a table for the number of dead circuits for every route to which each exchange unit can refer to. CONSTITUTION:Control processors P10, P20... of exchange units 10, 20... consituting a building block type exchange possess shared memory CM. Any control processor can attain access to CM and for every route, a table showing the number of dead circuits of each exchange unit is provided. As for the table for the number of dead circuits, the part of information on the unit can be rewritten by the control processor of the unit when the unit sets or resets a circuit.
