摘要：
A method for controlling bidirectional line protection switching by using a remote defect indication signal. The method includes the following steps of: inserting and transmitting a remote defect indication signal through the opposite directional link, in case the receiving end of working line detects a defect while a traffic is transmitted via a bidirectional link, and then switching to a back-up line by controlling the selector of the receiving station; and switching to the protection line by controlling the selector of the transmitting station, in case the remote defect indication signal is detected via the opposite directional link.
