  • Self-healing ring network and a method for fault detection and rectifying
    Patent number: 6728207
    Abstract: The present invention relates to a self-healing ring network and a method for fault handling in said network. Said network comprises two communication paths (1, 2) and at least two nodes (N1, N2, N3, N4, N5). A first node (N1) and a second node (N5) suppress transmission to and/or reception from a segment (IS) in the ring, called an inactive segment. In the case of an occurring fault, the inactive segment is moved to the fault. According to the invention the network comprises a separate supervisory channel (OSC) for transmitting information of the fault between the nodes (N1, N2, N3, N4, N5) of the network, in which supervisory channel (OSC) a fault flag (ASSERT_PSS) is provided for the indication of the fault.

  • Optical amplifier control
    Patent number: 6643055
    Abstract: A system and method for controlling the output power of an optical amplifier in a node in a network, wherein the output power of the amplifier is controlled via a pump laser in a control circuit. The node reads a supervisory channel comprising information on how to control the amplifier. The node then uses the information for the control of the amplifier.
