Source—The circuit source in the format: node/slot/port "port name"/VC. (Port name appears in
•
quotes.) Node and slot always appear; port "port name"/VC might appear, depending on the source
card, circuit type, and whether a name is assigned to the port. If the port uses a pluggable port
module (PPM), the port format is PPM-port number, for example, p2-1. If the port is a E1, DS-3, or
E3 port, port type is indicated, for example, pE1. If the circuit size is a concatenated size (VC4,
VC4-2c, VC4-3c, VC4-4c), VC high-order path used in the circuit are indicated by an ellipsis, for
example, S7..9, (VC high-order paths 7, 8, and 9) or S10..12 (VC high-order paths 10, 11, and 12).
Destination—The circuit destination in same format as the circuit source.

Cisco ONS 15310-MA SDH Procedure Guide, Release 9.1 and Release 9.2
Definition/Activity
A CTC-created circuit is missing a cross-connect or network
span or a complete path from source to destinations 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 PARTIAL. However, an PARTIAL status
does not necessarily mean a circuit traffic failure has
occurred, because traffic may flow on a protect path.
Network spans are in one of two states: up or down. On CTC
circuit and network maps, up spans appear as green lines,
and down spans appear 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 that 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 does not appear on the network map.
Subsequently, circuits routed on a network span that goes
down appear as DISCOVERED during the current CTC
session, but appear as PARTIAL to users who log in after the
span failure.
A TL1-created circuit or a TL1-like, CTC-created circuit is
complete. A complete path from source to destination(s)
exists.
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 destinations does not exist.
An existing circuit in a topology upgrade is set to this status.
The circuit returns to the DISCOVERED status when the
topology upgrade is complete.
Any new circuits created to represent an alternate path in a
topology upgrade are set to this status to indicate that they
are temporary circuits. These circuits can be deleted if a
topology upgrade fails.
A circuit is set to this status when a new circuit drop is being
added.
