プが形成されない欠点を生じている。However, in the past, when the transmission speeds of multiplexed channels were different, forming a return loop on all channels by transmitting a remote test signal on only one channel would cause confusion in the transmission status of other channels, so this method was not possible. In order to avoid this, remote test signals are transmitted from all channels, and when all of these signals are detected, loops are formed across all channels in response to this, which is necessary. Even if the remote test signal is transmitted only from a specific channel, a two-fold loop cannot be formed.
