Description
|
Name
|
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.
|
Type
|
(Display only.) VC_LO_PATH_AGGREGATION.
|
Size
|
(Display only.) VC4.
|
Bidirectional
|
(Display only.) Checked is the default for a LAP.
|
State
|
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 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,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.
|
Apply to drop ports
|
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:
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.
|
Revertive
|
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.
|
Reversion time
|
Available when Revertive is checked. Sets the amount of time 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.
|
SF threshold
|
Sets the SNCP path-level signal failure BER thresholds. Valid entries are IE-3, IE-4, and IE-5. Unavailable for low-order circuits.
|
SD threshold
|
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 circuits.
|
Switch on PDI-P
|
(Display only.) If checked, traffic switches when a VC4 payload defect indicator is received.
