SDH Numbering Convention

SDH Numbering Convention

As per ITU G.707, the high order paths are defined using a 2 to 5 level
convention E,D,C,B,A depending on the rate of the STM-n used.

E: the AUG-64 are numbered 1 to 4

D: the AUG-16 are numbered 1 to 4

C: the AUG-4 are numbered 1 to 4

B: the AUG-1 are numbered 1 to 4

A: the AU-3 are numbered 1 to 3

So for the naming is as follows for each of the following rate:

[E,D,C,B,A] for STM-256

[D,C,B,A] for STM-64

[C,B,A] for STM-16

[B,A] for STM-4

[0] for AU-4 in STM-1

[A] for AU-3 in STM-1

[A] for the AU-3 in STM-0e, A=0.
