In e SDH, payload has two mapping and multiplexing solutions:
In the ANSI multiplexing, lower order payload aggregates into the VC-3 higher or
path. A VC-3 plus an AU pointer forms an AU-3. An AUG generates through the
synchronous multiplexing of three such AU-3s.
In the ETSI multiplexing, lower order payload is aggregates into the VC-4 high
path. A VC-4 plus an AU pointer forms an A
synchronous multiplexing of such an AU-4.
