Abstract

Provides the mapping to be used for the transport of ATM cells over PDH at the various hierarchical bit rates defined in ITU-T Recommendation G.702. It covers both the 1544 kbit/s and 2048 kbit/s - based hierarchies and are used in conjunction with the frame structures defined in ITU-T Recommendation G.832.
