Abstract

PURPOSE:To perform transfer connection from an arbitrary general board to a corresponding specific board in a low link block rate, by connecting a small number of specific attendant boards through an additional link of one-stage constitution. CONSTITUTION:Incoming trunks ICTo-ICTn and many general attendant boards ATTo-ATT are directly stored in main link ML through position equipments POSo-POS , and a small number of supervisory attendant boards CATTo- CATTm are stored in main link ML through supervisory position equipments CPOSo-CPOSm and additional link CL of one-stage constitution. As a result, the number of degrees of freedom corresponding to the number of channels can be obtained by action of additional link CL, and transfer from general boards ATTo- ATT to supervisory boards CATTo-CATTm can be performed in a low link block rate with a complete group constitution.
