Abstract
A switching system having two-way lines connected between a primary office and an opposite office for communicating through a selected one of the two-way lines, and having a control unit for selecting one of the two-way lkines to be used for communication. To reduce double hunting of a two-way line, the control means comprises an outgoing connection process controlling unit for detecting a release of a two-way line activated by the primary office, an incoming connection process controlling unit for detecting a release of a two-way line activated by the opposite office, and a two-way line managing unit for deciding the priorities for selection of a plurality of two-way lines. The two-way line managing unit provides a different priority for selection to a released two-way line depending on whether the released two-way line had been activated by the primary office or by the opposite office.
