Table 7-2 Cisco ONS 15454 Circuit Status
Status Definition/Activity
CREATING CTC is creating a circuit.
DISCOVERED CTC created a circuit. All components are in place and a complete path exists
from the circuit source to the circuit destination.
DELETING CTC is deleting a circuit.
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 necessarily mean that a circuit traffic
failure has occurred, because traffic might flow on a protect path.
Network spans are in one of two states: up or down. On CTC circuit and
network maps, up spans are shown as green lines, and down spans are shown
as gray lines. If a failure occurs on a network span during a CTC session, the
span remains on the network map but its color changes to gray to indicate the
span is down. If you restart your CTC session while the failure is active, the
new CTC session cannot discover the span and its span line will not appear
on the network map.
Subsequently, circuits routed on a network span that goes down will appear
as DISCOVERED during the current CTC session, but they will appear as
PARTIAL to users who log in after the span failure.
This status does not appear for OCHNC circuit types.
DISCOVERED_TL1 A TL1-created circuit or a TL1-like CTC-created circuit is complete. A
complete path from source to destination(s) exists.
This status does not appear for OCHNC circuit types.
PARTIAL_TL1 A TL1-created circuit or a TL1-like CTC-created circuit is missing a
cross-connect, and a complete path from source to destination(s) does not
exist.
This status does not appear for OCHNC circuit types.
