Architecture for efficient processing of the evolving OTN transmission technology, standardized under ITU-T G.709, in conjunction with existing and emerging SONET/SDH protocol signals, standardized under ANSI T1.105/ITU-T G.707. The new architecture allows processing the SONET/SDH signals, and/or OTN signals, and/or SONET/SDH mapped into OTN signals more efficiently. The architecture further allows processing and multiplexing of lower order signals into a higher order signal such as quad OC-192 into OC-768 or quad OC-192 into OPU3 and OTU3. This architecture uses an embedded processor to process some of the signals' overhead in software, contributing to an additional level of flexibility in the processing. This architecture enables customization and allowing for future standard updates and upgrades. The architecture can be upgraded to SONET OC-3072, SDH STM-1024 and OTU4, which currently are not standardized. The architecture can also be used for the implementation of SONET OC-192 with OTN OTU2.
