摘要： An apparatus for monitoring of received information in a communication device comprises a first buffer having a plurality of storage elements adapted to store respective portions of the received information, a second buffer coupled to the first buffer and having a plurality of storage elements corresponding to respective ones of the storage elements of the first buffer, and controller circuitry coupled to the buffers and operative to detect a message sequence comprising a plurality of the portions of the received information. The second buffer stores a previously-detected message sequence loaded from the first buffer into the second buffer under control of the controller circuitry. The controller circuitry in detecting a current message sequence is configurable in at least first and second different monitoring modes each associated with a different message format. The monitoring mode of the controller circuitry may be adaptively configured based at least in part on a detected message sequence.

摘要： A communication device comprises a signal combiner, first storage elements, second storage elements and a controller. The signal combiner is configured to combine overhead information with additional information in forming a frame of a signal. The first storage elements are adapted to receive respective portions of a given block of the overhead information to be applied to the signal combiner, and the second storage elements are coupled between respective ones of the first storage elements and respective inputs of the signal combiner. The controller is operative to monitor a count of portions of the frame as the frame is formed by the signal combiner and to control loading of the portions of the given block of the overhead information into the second storage elements from the first storage elements responsive to the monitored count. The disclosed techniques for guaranteed consistent overhead insertion can be implemented in any type of communication system which utilizes overhead insertion in its framing operations.

摘要： Techniques are disclosed for in-band communication of alarm status information or other information between physical layer devices comprising a working device and a protection device in a network-based communication system. In one aspect, a protection receive signal is monitored in the protection device for the presence of alarm status information. The protection device encodes alarm status information extracted from the protection receive signal, and inserts the encoded alarm status information into one or more designated portions of a protection loop-back signal supplied from the protection device to the working device. The protection loop-back signal is monitored in the working device and the encoded alarm status information therein is decoded and utilized by the working device to initiate a protection switching operation.
