the following:
Nodal Diversity Required—Ensures that the primary and alternate paths within the SNCP ring
•
portions of the complete circuit path are nodally diverse.
Nodal Diversity Desired—Specifies that node diversity is preferred, but if node diversity is not
•
possible, CTC creates fiber-diverse paths for the SNCP ring portion of the complete circuit path.
Link Diversity Only—Specifies that only fiber-diverse primary and alternate paths for SNCP ring
•
portions of the complete circuit path are needed. The paths might be node diverse, but CTC does not
check for node diversity.
