7.2.5 Circuit Information in the Edit Circuit Window
You can edit a selected circuit using the Edit button on the Circuits window. The tabs that appear depend
on the circuit chosen:
•
•
•
•
•
•
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:
•
•
•
•
•
For BLSRs, the detailed map shows the number of BLSR fibers and the BLSR ring ID. For path
protection configurations, 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.
Alarms and states can also be viewed on the circuit map, including:

Circuit Protection Types (continued)
Description
The circuit is protected by diverse SONET topologies, for example a BLSR and a
path protection, or a path protection and 1+1.
A circuit has a source and destination on different nodes and communication is
down between the nodes. This protection type appears if not all circuit components
are known.
A circuit with a source and destination on different nodes is not protected.
A circuit created as a fully protected circuit is no longer protected due to a system
change, such as removal of a BLSR or 1+1 protection group.
The circuit is protected by a path protection.
General—Displays general circuit information and allows you to edit the circuit name.
Drops—Allows you to add a drop to a unidirectional circuit. For more information, see the
"7.5 Multiple Destinations for Unidirectional Circuits" section on page
UPSR Selectors—Allows you to change path protection selectors. For more information, see the
"7.6 Path Protection Circuits" section on page
UPSR Switch Counts—Allows you to change path protection switch protection paths. For more
information, see the
"7.6 Path Protection Circuits" section on page
State—Allows you to edit cross-connect service states.
Merge—Allows you to merge aligned circuits. For more information, see the
