摘要

The arrangement makes those lines available when all lines are busy that were busy for the original connection in order to form destination connections for a search and selection of a line by interrupting the connection formation used to make an original connection via this line. The calling subscriber receives an engaged tone for the interrupted original connection. Via the line concerned instead of the original connection the destination connection concerned is formed where traffic congestion at destination connections by original connections is avoided.
