Step 4 Click Next.
The Circuit Attributes page appears.
Type a circuit name in the Name field.
Step 5
Select the relevant size of the circuit from the Size drop-down list, and the appropriate state from the
Step 6
State list.
Verify that the signal degrade (SD) threshold is either set to 1E-6 (default) or in the 1E-6 to 1E-9 range
Step 7
in the SD threshold field.
If the SD threshold is the default (1E-6) or within the acceptable range, proceed to
a.
If the SD threshold is not the default (1E-6) or within the acceptable range, select 1E-6 or a threshold
b.
within the acceptable range from the drop-down list.
Lower SD thresholds increase the speed of CTC convergence, but also increase the possibility of
Note
interface flapping (repeatedly enabling and disabling) in some situations.
Step 8 Click Next.
The Source page appears.
Step 9 Select Node 1 as the source node from the node drop-down list.
Select the ML-Series card from the Slot drop-down list, and choose 0 (POS) from the Port drop-down
Step 10
list.
Click Next.
Step 11
The Destination page appears.
Select Node 2 as the destination node from the Node drop-down list.
Step 12
Select the ML-Series card from the Slot drop-down list, and choose 1 (POS) from the Port drop-down
Step 13
list.
Click Next.
Step 14
The Circuit Routing Preferences page appears.
Uncheck the Fully Protected Path check box.
Step 15
Click Next.
Step 16
The Circuit Constraints for Automatic Routing page appears.
Click the Node 1 icon to select it and click Next.
Step 17
The Route Review/Edit page appears.
Click Finish.
Step 18
You have now completed the initial circuit.
Note A TPTFAIL alarm might appear on CTC when the circuit is created. This alarm will disappear after the
POS ports are enabled during the
procedure on page
Build the second circuit between POS 0 on Node 2 and POS 1 on Node 3. Use the same procedure
Step 19
described in Steps
17-14.
1 through 18, but substitute Node 2 for Node 1 and Node 3 for Node 2.
