Figure 19-11 – Mapping of ODTU2.ts into 'ts' OPU2 1.25G tributary slots

19.3.6 ODTU3.ts mapping into ts OPU3 1.25G tributary slots
A byte of the ODTU3.ts payload signal is mapped into a byte of an OPU3 1.25G TS #i (i = 1,..,ts) payload
area, as indicated in Figure 19-12.

A byte of the ODTU3.ts overhead is mapped into a TSOH byte within columns 15 and 16, rows 1 to 3 of the
last OPU3 1.25G tributary slot allocated to the ODTU3.ts.

The remaining OPU3 TSOH bytes are reserved for future international standardization.
