Editing UPSR Circuits
Figure 6-6 Editing UPSR selectors
Procedure: Edit a UPSR Circuit
Step 1
Log into the source or drop node of the UPSR circuit.
Step 2
Click the Circuits tab.
Step 3 Click the circuit you want to edit, then click Edit.
Step 4 On the Edit Circuit window, click the UPSR tab.
Step 5 Edit the UPSR selectors:
•
Reversion Time—Controls whether traffic reverts to the working path when conditions that diverted
it to the protect path are repaired. If you select Never, traffic does not revert. Selecting a time sets
the amount of time that will elapse before traffic reverts to the working path.
•
SF Ber Level—Sets the UPSR signal failure BER threshold (STS circuits only).
•
SD Ber Level—Sets the UPSR signal degrade BER threshold (STS circuits only).
• PDI-P—When checked, traffic switches if an STS payload defect indication is received (STS
circuits only).
• Switch State—Switches circuit traffic between the working and protect paths. The color of the
Working Path and Protect Path fields indicates the active path. Normally, the Working Path is green
and the Protect Path is purple. If the Protect Path is green, working traffic has switched to the Protect
Path.
CLEAR—Removes a previously-set switch command.
LOCKOUT OF PROTECT—Prevents traffic from switching to the protect circuit path.
FORCE TO WORKING—Forces traffic to switch to the working circuit path, regardless of whether
the path is error free.
