Circuit States
The State column on the Circuits tab shows an aggregate of the cross-connect service states. For additional state information, see States.
If all circuit cross-connects are in the In-Service and Normal (IS-NR) service state, the circuit state is In-Service (IS).
If all circuit cross-connects are in an Out-of-Service (OOS) service state, the circuit state is OOS.
If circuit cross-connect service states are mixed and not all in the IS-NR service state, the circuit state is OOS-PARTIAL. The OOS-PARTIAL state can occur during automatic or manual transitions between states. For example, OOS-PARTIAL appears if some cross-connects are in the IS-NR service state while others are in the Out-of-Service and Autonomous, Automatic In-Service (OOS-AU,AINS) service state. 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.
