7.2.4 Circuit Information in the Edit Circuits Window
You can edit a selected circuit using the Edit button on the Circuits window. The tabs that appear depend
on the circuit chosen:
• General—Displays general circuit information and allows you to edit the circuit name.
• Monitors—Displays possible monitor sources and allows you to create a monitor circuit.
• Subnetwork Connection Protection—Allows you to change linear multiplex section protection
selectors. For more information, see the “7.6 Subnetwork Connection Protection Circuits” section
on page 7-9.
• Subnetwork Connection Protection Switch Counts—Allows you to change linear multiplex section
protection switch protection paths. For more information, see the “7.6 Subnetwork Connection
Protection Circuits” section on page 7-9.
• State—Allows you to edit cross-connect service states.
• Merge—Allows you to merge aligned circuits. For more information, see the “7.10 Merged
Circuits” section on page 7-22.
Using the Export command from the File menu, you can export data from the Linear Multiplex Section
Protection Selectors, Linear Multiplex Section Protection 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, VCs, and VTs 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 (linear multiplex section protection, unprotected, 1+1) and bandwidth (STMN)
Alarms and states can also be viewed 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 most severe alarm on port
• Loopbacks
• Path trace states
• Path selectors states
Unprot (red) A circuit created as a fully protected circuit is no longer protected due to a system
change, such as removal of a 1+1 protection group.
