UPSR Selectors
Use the UPSR Selectors tab to change the UPSR selectors (SF-BER, SD-BER), circuit protection switches, and other UPSR circuit parameters.
 
Item
Description
Node
Name of the UPSR circuit source node.
Working Path
Slot, port, specific STS (if applicable), and VT (if applicable) of the working path.
Protect Path
Slot, port, STS (if applicable), and VT (if applicable) of the protect path.
Revert Time
If Revertive is checked, sets the amount of time that will elapse before traffic reverts to the working path. The range is 0.5 to 12 minutes in 0.5 minute increments.
Switch State
Allows you to apply a traffic switch to the circuit. Valid entries are:
LOCKOUT OF PROTECT: Applies a LOCKOUT to prevent traffic from switching to the protect path.
FORCE TO WORKING: Applies a FORCE switch to move traffic to the working path.
FORCE TO PROTECT: Applies a FORCE switch to move traffic to the protect path.
MANUAL TO WORKING: Applies a MANUAL switch to move traffic to the working path.
MANUAL TO PROTECT: Applies a MANUAL switch to move traffic to the protect path.
Hold-Off Timer
Sets the amount of time a path selector switch is delayed for circuits routed on a UPSR or BLSR DRI topology. In DRIs, switching contention might occur depending upon the relative switching speed of the path selector and the transmission delay on the alternative routes. The hold-off timer (HOT) allows you to change switch times to prevent the switching contention.
SF Ber Level
Sets the UPSR signal failure BER threshold.
SD Ber Level
Sets the UPSR signal degrade BER threshold.
PDI-P
(STS circuits only) When checked, traffic switches if an STS payload defect indication is received.
Show Detailed Map
If checked, changes the circuit view in the graphic area to show circuit routing information including source slot, port, STS, and VT. The detailed view also shows working and protect circuit paths.
Show VT Topology
If checked, displays any VT tunnels that carry the VT circuit. If the circuit is not carried by a VT tunnel, no changes appear when the box is checked.
Show WDM Topology
(ONS 15454 only) If checked, hides the TXP and MXP connections on which STS and VT circuits are routed, showing only the logical OC-N links. This check box is available only when circuits are routed on TXP or MXP cards provisioned in section or line mode.
Apply
Applies any edits made to the UPSR Selectors tab.
Reset
Removes any edits made to the UPSR Selectors tab.
Help
Displays CTC context-sensitive help.
