UPSR to BLSR Upgrade
(ONS 15600 does not support this feature). Use the UPSR to BLSR Topology Conversion wizard to convert the path protection to a two-fiber BLSR. The wizard has four pages:
BLSR Attributes
Create BLSR
UPSR to BLSR Force Traffic
UPSR to BLSR Conversion
Note
Open-ended UPSR and UPSR dual ring interconnect (DRI) configurations do not support in-service topology upgrades.
