State
Use the State tab to view circuit segments and change the circuit state. The tab shows the individual circuit segment and cross-connect (CRS) endpoints from source node to destination.
 
Item
Description
Target Circuit Admin State
Lists the administrative states. An administrative state puts the circuit cross-connects into the related service state if network conditions allow:
No Change—The circuit state will not be changed.
unlocked—Puts the circuit cross-connects in the unlocked-enabled service state.
locked,disabled—Puts the circuit cross-connects in the locked-enabled,disabled service state. Traffic is not passed on the circuit.
locked,maintenance—Puts the circuit cross-connects in the locked-enabled,maintenance service state. The locked-enabled,maintenance service state does not interrupt traffic flow; it suppresses alarms and conditions and allows loopbacks to be performed on the circuit. Use the locked,maintenance administrative state for circuit testing or to suppress circuit alarms temporarily. Change the administrative state to unlocked; unlocked,automaticInService; or locked,disabled when testing is complete.
unlocked,automaticInService—Puts the circuit cross-connects in the unlocked-disabled,automaticInService service state. Alarms and conditions are suppressed. When the connections receive a valid signal, the service state automatically changes to unlocked-enabled.
locked,outOfGroup—(VCAT circuits only) Puts the circuit cross-connects in the locked-enabled,maintenance & outOfGroup service state. The locked,outOfGroup administrative state is used to place a VCAT member circuit out of the group and to stop sending traffic. locked,outOfGroup only applies to the cross-connect on the end node where the VCAT resides.
For additional state information, see States.
Apply to drop ports
If checked, applies the state chosen in the State field to the circuit source and destination ports. CTC applies the circuit state to the ports only in the following cases:
The circuit bandwidth is the same as the port bandwidth.
The port bandwidth is larger than the circuit and the circuit is the first circuit to use the drop port.
A Warning dialog box shows the ports where the circuit state could not be applied. If the box is unchecked, CTC does not change the state of the source and destination ports.
Node
Shows the node name of the circuit segment.
Name
Shows the circuit name.
End A
Shows the slot, port, and specific VC4/TUG3/TUG2/VC11/VC12 (if applicable) where the circuit enters the node. If IEEE 802.17 RPR mode is enabled, the port displays as pRPR East or pRPR West.
End B
Shows the slot, port, and specific VC4/TUG3/TUG2/VC11/VC12 (if applicable) where the circuit exits the node. If IEEE 802.17 RPR mode is enabled, the port displays as pRPR East or pRPR West.
CRS Admin State
Shows the administrative state of the cross-connects in the circuit segment (for example, unlocked).
CRS Service State
Shows the service state of the cross-connects in the circuit segment (for example, unlocked-enabled).
Show Detailed Map
If checked, changes the circuit view in the graphic area to show circuit routing information including source slot, port, and VC. The detailed view also shows working and protect circuit paths.
Show VC LO Topology
(ONS 15454 SDH only) If checked, displays any low-order path tunnels that carry the low-order path circuit. If the circuit is not carried by a low-order path tunnel, no changes appear when the box is checked.
Show WDM Topology
(ONS 15454 SDH only) If checked, hides the TXP and MXP connections where high-order and low-order circuits are routed, showing only the logical STM-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 changes made to the State tab.
Reset
Removes any changes made to the State tab.
Help
Displays CTC context-sensitive help.
