Abstract
PURPOSE:To reduce the operator trunks in the operator trunk connecting system, make unnecessary the operator link and to make sure the operation, by performing the connection between the exchanger board with the operator trunk with the main communication path switches. CONSTITUTION:The call from the caller 9 is incoming to the incoming trunk 5 via the exchanging station 7 and public communication network. Next, the operation of the common control unit 11 controls the main communication path switch 4, forming the communication path between the terminals 42 and 45 and between the terminals 41 and 44, and incoming is made to the exchange board 1. Fruther, the operator performs reception and selects the outgoing trunk 6 by controlling the switch 4 with the operation of the common control unit 11, connecting the terminals 43 and 46. Thus, the communication path between the caller 9 and the called party 10 is formed.
