•
Source—The circuit source in the format: node/slot/port “port name”/STS/VT . (The port name will
appear in quotes.) Node and slot will always appear; port “port name”/STS/VT might appear,
depending on the source card, circuit type, and whether a name is assigned to the port. If the circuit
is a concatenated size (3c, 6c, 12c, etc.), STSs used in the circuit are indicated by an ellipsis, for
example, “S7..9,” (STSs 7, 8, and 9) or S10..12 (STS 10, 11, and 12).
• Destination—The circuit destination in same format ( node/slot/port “port name”/STS/VT ) as the
circuit source.
•
# of VLANS—The number of VLANs used by an Ethernet circuit.
• # of Spans—The number of internode links that constitute the circuit. Right-clicking the column
shows a shortcut menu from which you can choose to show or hide circuit span detail.
•
State—The circuit service state, IS, OOS, or OOS-PARTIAL. The circuit service state is an
aggregate of the service states of its cross-connects:
– IS—All cross-connects are in the In-Service and Normal (IS-NR) service state.
–
OOS—All cross-connects are in the Out-of-Service and Management, Disabled
(OOS-MA,DSBLD) and/or Out-of-Service and Management, Maintenance (OOS-MA,MT)
service state.
– OOS-PARTIAL—At least one cross-connect is IS-NR and others are OOS-MA,DSBLD and/or
OOS-MA,MT.

Return to your originating procedure (NTP).
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,
an PARTIAL status does not necessarily mean 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.
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_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.
