11.2.5 Circuit Information in the Edit Circuit Window
• UPSR Switch Counts—Allows you to change path protection switch protection paths. For more
information, see the “11.7 SNCP Circuits” section on page 11-14.
• State—Allows you to edit cross-connect service states.
• Merge—Allows you to merge aligned circuits. For more information, see the “11.17 Merged
Circuits” section on page 11-33.
Using the Export command from the File menu, you can export data from the UPSR Selectors,
UPSR Switch Counts, State, and Merge tabs in HTML, comma-separated values (CSV), or tab-separated
values (TSV) format.
The Show Detailed Map checkbox in the Edit Circuit window updates the graphical view of the circuit
to show more detailed routing information, such as:
• Circuit direction (unidirectional/bidirectional)
• The nodes, VC4s, VC3/TUG3, TUG2s, VC12s, and VC11s through which the circuit passes,
including slots and port numbers
• The circuit source and destination points
• Open Shortest Path First (OSPF) area IDs
• Link protection (SNCP, unprotected, MS-SPRing, 1+1) and bandwidth (STM-N)
For MS-SPRings, the detailed map shows the number of MS-SPRing fibers and the MS-SPRing ring ID.
For SNCP rings, the map shows the active and standby paths from circuit source to destination, and it
also shows the working and protect paths. Selectors appear as pentagons on the detailed circuit map. The
map indicates nodes set up as dual-ring interconnect nodes. For VCAT circuits, the detailed map is not
available for an entire VCAT circuit. However, you can view the detailed map to view the circuit route
for each individual member.
You can also view alarms and states on the circuit map, including:
• Alarm states of nodes on the circuit route
• Number of alarms on each node organized by severity
• Port service states on the circuit route
• Alarm state/color of the most severe alarm on the port
• Loopbacks
• Path trace states
• Path selectors states
For example, in an SNCP, the working path is indicated by a green, bidirectional arrow, and the protect
path is indicated by a purple, bidirectional arrow. Source and destination ports are shown as circles with
an S and a D. Port service states are indicated by colors, shown in Table 11-4.
