Summary

Recommendation ITU-T G.7041/Y.1303 defines a generic framing procedure (GFP) to delineate octet-aligned, variable-length payloads from higher-level client signals for subsequent mapping into octet-synchronous paths such as those defined in Recommendations ITU‑T G.707/Y.1322, ITU‑T G.8040/Y.1340 and ITU-T G.709/Y.1331. This Recommendation defines:

–           frame formats for protocol data units (PDUs) transferred between GFP initiation and termination points;

–           the mapping procedure for the client signals into GFP;

–           responses to certain defect conditions.

This edition adds the information from both Amendment 2 (2010) to Recommendation ITU‑T G.7041 (2008) and the Implementers' Guide ITU-T G.Imp7041 (2009).
