Displays the circuit name. The name can be alphanumeric and up to 48 characters (including spaces). Circuit names should be 44 characters or less if you want to preserve the ability to create monitor circuits. If you leave the field blank, CTC assigns a default name to the circuit.
|
|
(Display only) VC_LO_PATH_CIRCUIT.
|
|
Sets the circuit size. Available low-order sizes are VC3, VC11 (with XC-VXC-10G card only), or VC12.
|
|
If checked, creates a bidirectional VC3, VC11 (with XC-VXC-10G card only), or VC12 circuit.
|
Create cross-connects only (TL1-like)
|
Creates one or more cross-connects to complete a signal path for TL1-generated circuits. If this box is checked, you cannot choose an E-Series card as a circuit source or destination. Also, nodes that do not support TL1 cross-connect naming will ignore the circuit name.
|
|
Lists the administrative states. An administrative state puts the circuit cross-connects into the related service state if network conditions allow:
• |
unlocked: Puts the circuit cross-connects in 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.
|
|
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.
|
Provision working go & return on primary path
|
If checked, the shortest path is the working path for both traffic directions. If unchecked, only one direction makes the shortest path the working path.
|
|
If checked, traffic reverts to the working path when the conditions that diverted it to the protect path are repaired. If unchecked, traffic remains on the protect path after the switch.
|
|
Available when Revertive is checked. Sets the amount of time (in minutes) that will elapse before traffic reverts to the working path. Traffic can revert when conditions causing the switch are cleared. The range is 0.5 to 12.0 minutes. The default is 5.0 minutes.
|
|
Sets the SNCP path-level signal failure BER thresholds. Valid entries are IE-3, IE-4, and IE-5. Unavailable for low-order circuits.
|
|
Sets the SNCP path-level signal degrade BER thresholds. Valid entries are IE-5, IE-6, IE-7, IE-8, and IE-9. Unavailable for low-order path circuits.
|
|
(Display only) If checked, traffic switches when a VC4 payload defect indicator is received.
|
Protected Drops (non-Ethernet)
|
If checked, CTC displays only protected cards as source and destination choices, that is, ONS cards that are in 1:1, 1:N, or 1+1 protection.
