    Long-haul transmission systems often require a supervisory system to accomplish such repeater control and monitor functions as switching in standby comp onents and measuring performance parameters. In an undersea system, it is impractical to provide a physically separate channel on which the repeater can send and receive supervisory signals. In SL, this problem is solved by embedding supervisory s... View full abstract»
