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.

portions of the complete circuit path are needed. The paths might be node diverse, but CTC does not
check for node diversity.
