An optical bi-directional line-switched ring transmission system includes a unit configured to transmit, from a transmission source node in a signal path for setting a cross-connect to an adjacent node, squelch information storing identity information of a transmission source node and a transmission destination node in a squelch information region provided in an optical overhead, in an own node that has received the squelch information, a unit configured to allocate cross-connect setting information based on the transmission source and transmission destination identity information, judge whether an own node is a transmission destination node or a through node of the cross-connect, execute through cross-connect setting in the own node; and-a notifying unit configured to, when the own node has been judged to be the transmission destination node of the cross-connect, notify a user with a message indicating that a cross-connect setting request exists.
