ONS 15327 Circuit Status
Table 8-1
lists the statuses that CTC can report for each
Definition/Activity
CTC is creating a circuit.
CTC created a circuit. All components are in place and a
complete path exists from the circuit source to the circuit
destination.
CTC is deleting a circuit.
A CTC-created circuit is missing a cross-connect or network
span; a complete path from source to destination(s) does not
exist.
In CTC, circuits are represented using cross-connects and
network spans. If a network span is missing from a circuit,
the circuit status is INCOMPLETE. However, an
INCOMPLETE status does not necessarily mean a circuit
traffic failure has occurred, because traffic can flow on a
protect path.
Network spans are in one of two states: up or down. In CTC
circuit and network maps, up spans are displayed as green
lines, and down spans are displayed 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. 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 display on the network map.
Subsequently, circuits routed on a network span that goes
down will display as ACTIVE during the current CTC
session, but they will display as INCOMPLETE to users who
log in after the span failure.
A TL1-created circuit or a TL1-like CTC-created circuit is
complete and has upgradable cross-connects. A complete
path from source to destination(s) exists. CTC can create an
active circuit.
A TL1-created circuit or a TL1-like CTC-created circuit
with upgradable cross-connects is missing a cross-connect,
and a complete path from source to destination(s) does not
exist. The circuit cannot be upgraded until missing
cross-connects are in place.
