Overhead Circuit Statuses
The following table shows the overhead circuit statuses that might appear in the Status column of the Overhead Circuits tab.
 
Overhead Circuit Status
Description
CREATING
CTC is creating an overhead circuit.
DISCOVERED
CTC created an overhead circuit. All components are in place and a complete path exists from circuit source to destination.
DELETING
CTC is deleting an overhead circuit.
PARTIAL
A CTC-created overhead circuit is missing a cross-connect or network span; a complete path from source to destination(s) does not exist, or an alarm interface panel (AIP) change occurred on one of the circuit nodes and the circuit is in need of repair. (AIPs store the node MAC address.)
In CTC, circuits are represented using cross-connects and network spans. If a network span is missing from a circuit, the circuit status is PARTIAL. However, a PARTIAL status does not necessarily mean that a circuit traffic failure has occurred, for traffic might flow on a protect path.
LOOP_FORMING
This status appears only for orderwire circuits. It indicates the orderwire circuit has been provisioned in a loop.
UPDATING
The circuit is being updated.
