Abstract
PURPOSE: To prevent occurrence of the division loss for the intrruption circuit by giving an interruption connection from the general incoming trunk in that route of the main frame, the special trunk for interruption, the main frame interruption channel and to the main frame interrupted channel and thus giving an interruption connection from all incoming trunks.
CONSTITUTION: An incoming is given to general incoming trunk 6 from the operator, and an interruption connection is requested from the operator via the line signal with the called subscriber being under the busy state. In that case, an interruption connection is given from trunk 6 in that route of the main frame 3, special trunk 7 for interruption, the main frame interruption channel, the main frame interrupted channel and to the called subscriber. Thus, the interruption connection is given from all incoming trunks to prevent occurrence of the division loss for the interruption circuit.
