Abstract
An optical transport network data frame structure is configured to provide an in-band data channel. The in-band channel data is contained in the data frame space that would otherwise be allocated to forward error correction ('FEC') bytes. Consequently, the provision of the in-band data channel does not affect the number of client data bytes contained in the data frame structure. In accordance with a practical embodiment, the data frame structure is compliant with Intra Domain Interface (IaDI) specifications set forth in International Telecommunication Union Telecommunication Standardization Sector (ITU-T) Recommendation Guide For Recommendation, G.709/Y.1331.
