Description
|
Node
|
Name of the UPSR circuit source node.
|
Working Path
|
Slot, port, specific synchronous transport signal (STS) (if applicable), and virtual tributary (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
working path.
MANUAL TO WORKING: Applies a MANUAL switch to move traffic to
the working path.
FORCE TO PROTECT: Applies a MANUAL switch to move traffic to the
working path.
|
Hold-Off Timer
|
Sets the amount of time a path selector switch is delayed for circuits routed on a UPSR or BLSR dual-ring interconnect (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 time (HOT) allows you to change switch times to prevent the switching contention.
|
SF Ber Level
|
Sets the UPSR signal failure bit error rate (BER) threshold.
|
SD Ber Level
|
Sets the UPSR signal degrade BER threshold.
|
PDI-P
|
When checked, traffic switches if an STS payload defect indication is received (STS circuits only).
|
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 transponder (TXP) and muxponder (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.
