Sets 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) Displays the circuit type chosen in the Circuit Creation page.
|
|
(Display only) Checked is the default for an STS VCAT circuit.
|
Create cross-connects only (TL1-like)
|
Creates one or more cross-connects to complete a signal path for TL1-generated circuits. 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:
• |
OOS,DSBLD —Puts the circuit cross-connects in the OOS-MA,DSBLD service state. Traffic is not passed on the circuit. |
• |
IS —Puts the circuit cross-connects in the IS-NR service state. |
• |
IS,AINS —Puts the circuit cross-connects in the OOS-AU,AINS service state. Alarms and conditions are suppressed. When the connections receive a valid signal, the service state automatically changes to IS-NR. |
• |
OOS,MT —Puts the circuit cross-connects in the OOS-MA,MT service state. The OOS-MA,MT service state does not interrupt traffic flow; it suppresses alarms and conditions and allows loopbacks to be performed on the circuit. Use the OOS,MT administrative state for circuit testing or to suppress circuit alarms temporarily. Change the administrative state to IS; IS,AINS; or OOS,DSBLD when testing is complete. |
• |
OOS,OOG —(VCAT link capacity adjustment scheme [LCAS] circuits only) Puts the circuit cross-connects in the Out-of-Service and Management, Maintenance and Out-of-Group (OOS-MA,MT & OOG) service state. The OOS,OOG administrative state is used to place a VCAT member circuit out of the group and to stop sending traffic. OOS,OOG 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.
|
|
(Display only) Provisions the same number of members in both directions. Checked is the default for an STS VCAT circuit. Members use the same set of time slots but in opposite directions.
|
|
If checked, creates an open-ended VCAT circuit.
|
|
Sets the member size of the STS-V.
Valid entries for the ONS 15454 nodes are:
• |
FC_MR-4 (both line rate and enhanced modes) —STS-1 and STS-3c |
• |
ML-Series —STS-1, STS-3c, and STS-12c |
|
|
Sets the number of members.
ONS 15454 cards support the following members:
• |
CE-1000-4 —1 to 21 at STS-1 and 1 to 7 at STS-3 |
• |
FC_MR-4 (line rate mode) —24 (1 Gbps port) or 48 (2 Gbps port) for STS-1 circuits; 8 (1 Gbps port) or 16 (2 Gbps port) for STS-3c circuits |
• |
FC_MR-4 (enhanced mode) —1 to 24 (1 Gbps port) or 1 to 48 (2 Gbps port) for STS-1 circuits; 1 to 8 (1 Gbps port) or 1 to 16 (2 Gbps port) for STS-3c circuits |
• |
ML-Series —2 for STS-1, STS-3c, and STS-12c circuits |
|
|
Sets the VCAT circuit mode:
• |
None—No mode is provisioned. |
• |
Sw-LCAS—Allows temporary removal of an existing member when a member fails. The failed member is removed for the duration of the failure. Use Sw-LCAS if interoperating with the ONS 15454 ML-Series cards, which do not support the full LCAS functionality. |
• |
LCAS —(ONS 15454 with CE-100T-8 and CE-1000-4 cards only) Allows the members in a VCAT group to be changed without interrupting the operation of uninvolved members (errorless). In addition, when a member fails, LCAS temporarily removes the failed member from the VCAT circuit for the duration of the failure, leaving the remaining members to carry the traffic. |
|
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 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 UPSR path-level signal failure BER thresholds. Valid entries are IE-3, IE-4, and IE-5.
|
|
Sets the UPSR path-level signal degrade BER thresholds. Valid entries are IE-5, IE-6, IE-7, IE-8, and IE-9.
|
|
If checked, traffic switches when an STS payload defect indicator is received.
