Abstract
Where an integrated monitoring and controlling unit is to control an optical add-drop unit so as to cause transmit signals from the optical transceiver of a first optical node to be received by the optical transceivers of plural different optical nodes, this purpose can be achieved by an optical transmission system provided with an alarm inhibiting device that can inhibit the optical transceiver, which is a source of transmission, from issuing any unexpected alarm.
