1.11.1 OC-N Circuit Transitions to Partial State
Symptom
OOS-PARTIAL status, which indicates that not all OC-N connections in the circuit are in the IS-NR
service state.
View the State of OC-N Circuit Nodes
Click the Circuits tab.
Step 1
From the Circuits tab list, select the circuit with the *_PARTIAL status condition.
Step 2
Click Edit. The Edit Circuit window appears.
Step 3
In the Edit Circuit window, click the State tab (if you are viewing a SONET circuit).
Step 4
The State tab window lists the Node, End A, End B, CRS Admin State, and CRS Service State for each
of the nodes in the circuit.

state and determine the version of software. If the software on the node is Software R3.3 or earlier,
upgrade the software. Refer to the release-specific software upgrade document for procedures.
Note If the node software cannot be upgraded to R4.0, the partial state condition can be avoided
by using only the circuit state supported in the earlier software version.
During an automatic transition, some path-level defects and/or alarms were detected

instructions to change circuit configuration settings. Resolve and clear the defects and/or alarms on
the circuit node and verify that the circuit transitions to the desired state.
