If a Release 5.02 ONS 15600 node is in a BLSR with Release 7.0 ONS 15454 nodes and the login node

is a Release 7.0 node, the Circuits window Protection column displays Unknown and the Status column
displays CONVERSION_PENDING. This status occurs until the ONS 15600 node is running Release
7.0 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:
•
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.
Definition/Activity
A TL1-created circuit or a TL1-like, CTC-created circuit is
complete. A complete path from source to destination(s)
exists.
A TL1-created circuit or a TL1-like, CTC-created circuit is
missing a cross-connect or circuit span (network link), and
a complete path from source to destination(s) does not exist.
An existing circuit in a topology upgrade is set to this state.
The circuit returns to the DISCOVERED state when the
topology upgrade is complete. For more information about
topology upgrades, see
Chapter 8, "SONET Topologies and
Upgrades."
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.
