DLP- D234 Roll the Source or Destination of One Optical Circuit
• (VC4 circuits only) In the VC LO Circuits Only area, set the following thresholds:
–
SF threshold—Sets the SNCP signal failure BER threshold.
–
SD threshold—Sets the SNCP signal degrade BER threshold.
• (VC4 circuits only) In the VC4 Circuits Only area, set the following thresholds:
–
SF Ber Level—Sets the SNCP signal failure BER threshold.
–
SD Ber Level—Sets the SNCP signal degrade BER threshold.
–
Switch on PDI-P—When checked, traffic switches if an VC4 payload defect indication is
received.
Step 6 Click OK and verify that the changed values are correct in the Circuits window.
Step 7 Return to your originating procedure (NTP).
DLP-D234 Roll the Source or Destination of One Optical Circuit
Step 1 From the View menu, choose Go To Network View.
Step 2 Click the Circuits tab.
Step 3 Click the circuit that you want to roll. The circuit must have a DISCOVERED status for you to start a
roll.
Step 4 From the Tools menu, choose Circuits > Roll Circuit.
Step 5 In the Roll Attributes area, complete the following (Figure 19-5):
a. From the Circuit Roll Mode drop-down list, choose Auto to create an automatic roll (required for a
1-way source roll) or Manual to create a manual roll (required for a 1-way destination roll).
b. From the Circuit Roll Type drop-down list, choose Single to indicate that you want to roll one
cross-connect on the chosen circuit.
Purpose This task reroutes traffic from one source or destination to another on the
same circuit, thus changing the original source or destination.
