DLP- D230 Change a Circuit State
In the Circuits on Span dialog box, you can view the following information about the circuits that
traverse the span. The information that appears depends on the circuit type. For low-order and high-order
circuits provisioned on the span, the following information appears:
• VC4—Displays VC4s used by the circuits.
• VC3/TUG3—Displays VC3s and TUG3s used by the circuits.
• TUG2—Displays TUG2s used by the circuits.
• VC12—Displays VC12s used by the circuits.
• VC11—Displays VC11s used by the circuits.
• SNCP—(SNCP span only) If checked, SNCP circuits are on the span.
• Circuit—Displays the circuit name.
• Switch State—(SNCP span only) Displays the switch state of the circuit, that is, whether any span
switches are active. For SNCP spans, switch types include: CLEAR (no spans are switched),
MANUAL (a manual switch is active), FORCE (a force switch is active), and LOCKOUT OF
PROTECTION (a span lockout is active).
Note You can perform other procedures from the Circuits on Span dialog box. If the span is in an
SNCP, you can switch the span traffic. See the “DLP-D197 Initiate an SNCP Force Switch” task
on page 18-84 for instructions. If you want to edit a circuit on the span, double-click the circuit.
See the “DLP-D231 Edit a Circuit Name” task on page 19-28 or the “DLP-D233 Edit SNCP
Circuit Path Selectors” task on page 19-30 for instructions.
Step 3 Return to your originating procedure (NTP).
DLP-D230 Change a Circuit State
Step 1 From the View menu, choose Go to Network View.
Step 2 Click the Circuits tab.
Step 3 Click the circuit with the state you want to change.
Note You cannot edit the circuit state if the circuit is routed to nodes with Software Release 3.3. These
circuits are automatically in service (Unlocked).
Step 4 From the Tools menu, choose Circuits > Set Circuit State.
Purpose This task changes the state of a circuit.
