Note If an ONS 15600 node is running Software R5.0.2, it is in a BLSR with an ONS 15454 node running
Software R7.0 or later, and the login node is running Software R7.0 or later, the Protection column in
the CTC Circuits window will show "Unknown" and the Status column will show
"CONVERSION_PENDING." This status occurs until the ONS 15600 node is running Release 7.0 or
later software.

7.2.3 Circuit States

The circuit service state is an aggregate of the cross-connect states within the circuit.
•
•
•
You can assign a service state to circuit cross-connects at two points:
•
•
After you have created an initial circuit in a CTC session, the subsequent circuit states default to the
Note
circuit state of the initial circuit, regardless of which nodes in the network the circuits traverse or the
node.ckt.state default setting.
During circuit creation, you can apply a service state to the drop ports in a circuit. You cannot transition
a drop port from the IS-NR service state to the OOS-MA,DSBLD service state; you must first put the
port in the OOS-MA,MT state before changing it to the OOS-MA,DSBLD state. For more information
about port service state transitions, see
ONS 15600 Circuit Status (continued)
If all cross-connects in a circuit are in the IS-NR service state, the circuit service state is
In-Service (IS).
If all cross-connects in a circuit are in an OOS service state, such as OOS-MA,MT; Out-of-Service
and Autonomous, Automatic In-Service (OOS-AU,AINS); or Out-of-Service and
Management, Disabled (OOS-MA,DSBLD) service state, the circuit service state is
Out-of-Service (OOS).
PARTIAL is appended to the OOS circuit service state when circuit cross-connects state are mixed
and not all in IS-NR. The OOS-PARTIAL state can occur during automatic or manual transitions
between states. OOS-PARTIAL can appear during a manual transition caused by an abnormal event
such as a CTC crash or communication error, or if one of the cross-connects could not be changed.
Refer to the Cisco ONS 15600 Troubleshooting Guide for troubleshooting procedures.
During circuit creation, you can set the state on the Create Circuit wizard.
After circuit creation, you can change a circuit state in the Edit Circuit window or from the
Tools > Circuits > Set Circuit State menu.
Definition/Activity
Any new circuits created to represent an alternate path in a
topology upgrade are set to this status to indicate that it is a
temporary circuit. These circuits can be deleted if a topology
upgrade fails. For more information about topology
upgrades, see Chapter 8, "SONET Topologies and
Upgrades."
A circuit is set to this status when a new circuit drop is being
added.
