Circuit Statuses


The following table describes the circuit statuses that can appear on the Circuits tab.

Circuit Status

Description

CREATING

CTC is creating a circuit.

DELETING

CTC is deleting a circuit.

DISCOVERED

CTC created a circuit. All components are in place and a complete path exists from circuit source to destination.

DISCOVERED_TL1

A TL1-created circuit or a TL1-like CTC-created circuit is complete. A complete path from source to destination(s) exists.

PARTIAL

A CTC-created 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 always mean a circuit traffic failure has occurred, because traffic might flow on a protect path.

PARTIAL_TL1

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.
