3.9.16 createAndActivateSNCFromUserLabel
For protected OCHNC and OCHCC circuits, this parameter defines only the inclusion routing
constraints for the working path of the circuit. To define the constraints for the protected path, CTM
provides the additional info parameters “includedProtectedME” and “excludedProtectedME.”
• boolean fullRoute
Not supported.
• ResourceList_T neTpSncExclusions
Supported. CTM expects a list of managed element names or the PTP names at the endpoints of the
TopologicalLink to exclude from the SNC route.
For protected OCHNC and OCHCC circuits, this parameter defines only the exclusion routing
constraints for the working path of the circuit. To define the constraints for the protected path, CTM
provides the additional info parameters “includedProtectedME” and “excludedProtectedME.”
• globaldefs::NamingAttributesList_T aEnd
Supported. CTM expects at least one valid CTP or FTP in this list. At most, two valid CTPs can be
in the list.
• globaldefs::NamingAttributesList_T zEnd
Supported. CTM expects at least one valid CTP or FTP in this list. At most, two valid CTPs can be
in the list.
• globaldefs::NVSList_T additionalCreationInfo
This list can be used to provide additional parameters for SNC creation. The following table
provides additional CTM-supported parameters for SNC creation. For more information, refer to the
ONS 15454 SONET user documentation.
Table 3-4 CTM-Supported Parameters for SNC Creation
Name Value Description
upsrRevertiveMode Revertive or
nonrevertive
If the value is set to revertive, traffic reverts back to the working path
when the conditions that diverted it to the protect path are repaired;
otherwise, traffic remains on the protect path after the switch.
upsrRevertiveTime Valid float value from
0.5 to 12, in increments
of 12
If the SNC is revertive, you must set this parameter. This is the
amount of time that elapses before traffic reverts back to the working
path. The default value is 5 minutes.
Note CTM does not validate this value.
upsrSfBerLevel 3, 4, or 5 Set the thresholds for path protection, path-level signal failure, and bit
error rate (only for STS SNCs).
Note CTM does not validate this value.
upsrSdBerLevel 5, 6, 7, 8, 9 Set the thresholds for path protection, path-level signal degrade, and
bit error rate (only for STS SNCs).
Note CTM does not validate this value.
upsrSwitchOnPdiP True or false Set this to true if you want traffic to switch when an STS payload
defect indicator is received (only for STS SNCs).
goAndReturnRouting True or false Set this to true if you want to provision SNCP/path-protection routes
in Go and Return fashion (ITU-T G.841); otherwise,
SNCP/path-protection routes are provisioned in unidirectional
fashion following GR-1400.
