G.709 OTN Label Space - Definitions
Label Structure defined as Tree:
- Root: OTUk signal and Leaves: ODUj signals (k ? j)
3 fields k1, k2 and k3 self-consistently characterising ODUk label space
- k1 (1-bit): unstructured client signal mapped into ODU1 (k1 = 1) via OPU1
- k2 (3-bit): unstructured client signal mapped into ODU2 (k2 = 1) via OPU2 or the position of ODU1 tributary slot in ODTUG2 (k2 = 2,..,5) mapped into ODU2 (via OPU2)
- k3 (6-bit): unstructured client signal mapped into ODU3 (k3 = 1) via OPU3 or the position of ODU1 tributary slot in ODTUG3 (k3 = 2,..,17) mapped into ODU3 (via OPU3) or the position of ODU2 tributary slot in ODTUG3 (k3 = 18,..,33) mapped into ODU3 (via OPU3)
