Summary

This Recommendation provides the mapping to be used for the transport of GFP frames over PDH at the various hierarchical bit rates defined in ITU-T Rec. G.702. This mapping covers the N × 1544 kbit/s, N × 2048 kbit/s, N × 44 736 kbit/s, and N × 34 368 kbit/s signals and is used in conjunction with the frame structures defined in ITU-T Recs G.704 and G.7043/Y.1343.
