Zusammenfassung:	PROBLEM TO BE SOLVED: To transfer a ring transmission system built up as a unidirectional path switched ring(UPSR) system into a bidirectional path switched ring(BLSR) system while keeping in-service state of lines in the method of transferring a ring transmission system to a different system and its transmitter. SOLUTION: A control panel 1h of the UPSR system is replaced with a control panel of the BLSR system. A multiplexer/demultiplexer conversion panel 1e of the UPSR system at a standby side is replaced with a 1st multiplexer/demultiplexer conversion panel of the BLSR system set for the operation of the UPSR system by switching a path switch 1g. Furthermore, the path switch 1g is again switched to replace a multiplexer/demultiplexer conversion panel 1b of the UPSR system at a standby side with a 2nd multiplexer/demultiplexer conversion panel of the BLSR system set for the operation of the UPSR system. Then the 1st and 2nd multiplexer/demultiplexer conversion panels are operated for the BLSR system to change the line arrangement from the UPSR system into the BLSR system.
