DLP-H242 Create a 1+1 Protection Group for the ONS 15310-MA SDH
Purpose
This task changes the amount of time a path selector switch is delayed for
circuits routed on a path protection dual-ring interconnect (DRI) topology.
Setting a switch hold-off time (HOT) prevents unnecessary back and forth
switching when a circuit is routed through multiple path protection
selectors.
