Abstract

PURPOSE:To reduce a using frequency of a subscriber circuit and to shorten the time necessary for selection of the subscriber circuit by checking the state of the next subscriber circuit in accordance with contents of a circuit selection pointer recording circuit when the circuit state is not idle. CONSTITUTION:When a call signal S1 is transmitted from a calling subscriber terminal, for instance, to a trailing end part 3i of a channel through a channel 1i, the trailing end part 3i transmits the call signal S1 to control part 8. When a subscriber circuit state 11ij is idle, the control part 8 commands a channel connection circuit 7 on connecting a channel between the trailing end part 3i and a subscriber circuit connection part 6ij, and sets the circuit state 11ij during communications. When the circuit state 11ij is not idle, contents of the next subscriber circuit state 11ih are checked in accordance with the contents of a circuit selection pointer 13i, which are updated simultaneously. Thus the using frequency of the subscriber circuit is reduced, and the time necessary for the selection of the subscriber circuit can be shortened.
