Abstract
A terminal for a bidirectional synchronous digital hierarchy link with automatic protection switching conveying multiplexed data includes two send devices. Each send device includes a device for extracting from each of the two SDH multiplexes a signal indicating a far end remote failure. It further includes a device for receiving two SDH multiplexes and multiplexing them with service data specific to the link with automatic protection switching into a single multiplex to be sent over a first line. It inserts into this service data the two far end remote failure signals and two additional far end remote failure signals, these two additional signals being supplied by the other send device. The terminal further includes an automatic protection switch for transmitting to the first line one of the two multiplexes supplied by the respective send devices. Applications include underwater links.
