SONET/DSn/SDH/PDH
The FTB-700G/800 Series supports numbering SONET low order path using
the two-level “VTGroup#,VT#” convention for numbering VTs within an
STS-1. For example: VT1.5 [1,3], VT2 [3,2], VT6 [6,1].
The FTB-700G/800 Series supports numbering SONET high order path
STS-nc within an OC-N using the two-level “STS-3#,STS-1#”. For example:
STS-12c [5,1].
Note:
For STS-1e the numbering is limited to the A value as only one STS-1 exits.
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
