摘要： A transponder unit which relays signals between a plurality of channels of an optical transport network and a plurality of clients. The interconnections within the transponder unit are reconfigurable for selective connections. A connection between a first client and a first network channel and a connection between a second client and a second network channel is independent of each other and may be selected so that the second client is connected to the first network channel and the first client is connected to the second network channel. Other selected connections are also possible.

摘要： Methods and apparatus for allowing a dense wave division multiplexing (DWDM) line card w to function as an add/drop multiplexer (ADM), a transponder, and a muxponder are disclosed. According to one aspect of the present invention, a line card suitable for use in a network to aggregate signals of different line rates for transport includes a first arrangement having ADM functionality, a second arrangement having transponder functionality, and a third arrangement having muxponder functionality. The line card also includes hardware that facilitates communication between the arrangements, as well as a plurality of ports arranged to receive a signal and to provide the signal to the hardware.

摘要： Methods and apparatus for processing a failure and a subsequent recovery in a ten Gigabit Ethernet (GE) optical transport network (OTN) wave division multiplexing (WDM) ring are disclosed. According to one aspect of the present invention, a device includes a plurality of ports, a sensing arrangement, and a processing arrangement. The ports include a first port that is initially configured to be in a forwarding state, and the sensing arrangement identifies whether the first port is facing or interfaced with a failure associated with the network ring. The processing arrangement being generates at least a first G.709 frame, and inserts at least one bit into the first G.709 frame that indicates that the failure associated with the network ring has been identified if the first port is facing a failure. The processing arrangement forwards the first G.709 frame through the second port.

摘要： Techniques for providing ADM functionality to an optical (OTN/DWDM) ring are provided. A pair of muxponder components are utilized to form a transparent ADM. In one muxponder, transmit signals are sent in a first direction and receive signals are received from a second direction. In the other muxponder, transmit signals are sent in the second direction and received from the first direction.
