摘要： A system and method have been provided for translating digitally wrapped communications between networks using different protocols. This invention makes use of an integrated circuit (IC) relay with programmable features to modify the locations and functions of overhead bytes between the receive and transmit sides of the device, permitting two dissimilar networks to be bridged. That is, the IC relay converts frame formatting from one frame structure to another, so that incompatible networks can communicate.

摘要： A system and method are provided for generating alarms from forward error correction (FEC) data in a G.709 network-connected integrated circuit. The method includes: receiving messages including forward error correction bytes; using the forward error correction bytes to detect errors in the messages; and, generating alarm signals in response to the detected errors. Generating alarm signals in response to the detected errors includes generating a signal degrade (SD) signal in response to detecting a first number of errors (error density) within a predetermined time period. Likewise, generating alarm signals in response to the detected errors includes generating a signal fail (SF) signal in response to detecting a second number of errors (second error density), greater than the first number, within the predetermined time period. The method further includes: selecting an error type. Then, alarm signals are generated in response to the selected error type. The error types include a “1s” density alarm, a “0s” density alarm, a bytes density alarm, and a sub-row density alarm.

摘要： A system and method are provided for paralleling data streams in a G.709 network of connected integrated circuits. The system comprises a demultiplexer for receiving a first digital wrapper data stream having a first data rate. The demultiplexer demultiplexes the first data stream into a second plurality of digital wrapper data streams having a second data rate, less than the first data rate. A second plurality of processors each accept a corresponding one of the second plurality of data streams and supply a processed data stream at the second data rate. The demultiplexer receives frame alignment signal bytes in the overhead of every first data stream frame and synchronizes frame alignment signal bytes in each of the second plurality of data streams to the frame alignment signal bytes in the first data stream.
