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) Displays the type chosen in the Circuit Creation page.
|
Bidirectional
|
(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.
|
State
|
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 Out-of-Service and
Management, Disabled (OOS-MA,DSBLD) service state. Traffic is not
passed on the circuit.
IS-Puts the circuit cross-connects in the In-Service, Normal (IS-NR)
service state.
IS,AINS-Puts the circuit cross-connects in the Out-of-Service and
Autonomous, Automatic In-Service (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 Out-of-Service and
Management, Maintenance (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,
Out-of-Group (OOS-MA,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.
|
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.
|
Symmetric
|
(Display only) Checked is the default for an STS VCAT circuit. The Symmetric option provisions the same number of members in both directions. Members use the same set of time slots but in opposite directions.
|
Member size
|
Sets the member size for the STS-V. Valid entries for the ONS 15310-CL nodes are:
CE-100T-8-STS-1
ML-100T-8-STS-1
Valid entries for the ONS 15454 nodes are:
CE-100T-8-STS-1
FC_MR-4 (both line rate and enhanced modes)-STS-1 and STS-3c
ML-Series-STS-1, STS-3c, and STS-12c
|
Num. of Members
|
Sets the number of members.
ONS 15310-CL cards support the following members:
CE-100T-8-1 to 3
ML-100T-8-1 to 3
ONS 15454 cards support the following members:
CE-100T-8-1 to 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
|
Mode
|
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 ML-Series cards, which do not support
the full Link Capacity Adjustment Scheme (LCAS) functionality.
LCAS: (ONS 15310-CL CE-100T-8 and ML-100T-8 cards and ONS 15454
CE-100T-8 cards only) Allows the members in a VCAT group to be changed
without interrupting the operation of noninvolved 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.
|
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 unidirectional path switched ring (UPSR) path-level signal failure bit error rate (BER) thresholds. Valid entries are IE-3, IE-4, and IE-5.
|
SD threshold
|
Sets the UPSR path-level signal degrade BER thresholds. Valid entries are IE-5, IE-6, IE-7, IE-8, and IE-9.
|
Switch on PDI-P
|
If checked, traffic switches when an STS payload defect indicator is received.
