Figure 19-12 – Mapping of ODTU3.ts into 'ts' OPU3 1.25G tributary slots

19.3.7 ODTU4.ts mapping into ts OPU4 1.25G tributary slots

A byte of the ODTU4.ts payload signal is mapped into a byte of an OPU4 1.25G TS #i (i = 1,..,ts) payload
area, as indicated in Figure 19-13.

A byte of the ODTU4.ts overhead is mapped into a TSOH byte within columns 15 and 16, rows 1 to 3 of the
last OPU4 1.25G tributary slot allocated to the ODTU4.ts.
The remaining OPU4 TSOH bytes are reserved for future international standardization.
