Only one instance can be created in one NE. When the establishProtection action is successfully performed one sdhMSProtectionGroup instance and as many sdhMSProtectionUnit instances are created as specified by the action information. The unreliableResourcePointer of each sdhMSProtectionUnit will point to the unprotectedCTP indicated by the unreliableObjects field of the action information. The reliableResourcePointer will point to the protectedTTP connected to the unprotectedCTP, unless the protectionUnit is protecting and extra-traffic is not required or not supported. In this case the reliableResourcePointer is NULL. UnprotectedCTPs and protectedTTPs are anyhow instantiated for sections which can potentially be included in a protection group irrespective whether protection is actually present or not. When a section is not part of a protection group, the crossConnectionObjectPointer of the unprotectedCTP and protectedTTP point to the sdhMSProtectionCoordinator object instance. When protection is established the crossConnectionObjectPointer points to the associated sdhMSprotectionUnit. When it is possible, unprotectedCTPs and protectedTTPs may be created/deleted as a result of the establish/modify/dismiss actions.*; protectionCoordinatorId ATTRIBUTE WITH ATTRIBUTE SYNTAX SDHProtCoordASN1.NameType; MATCHES FOR EQUALITY; BEHAVIOUR protectionCoordinatorIdBeh; REGISTERED AS {g774-09Attribute 1}; protectionCoordinatorIdBeh BEHAVIOUR DEFINED AS *The protectionCoordinatorId attribute is an attribute type whose distinguished value can be used as an RDN when naming an instance of the protectionCoordinator object class.*; dismissProtection ACTION BEHAVIOUR dismissProtectionBeh; MODE CONFIRMED; WITH INFORMATION SYNTAX SDHProtCoordASN1.DismissProtectionInfo; REGISTERED AS {g774-09Action 1}; dismissProtectionBeh BEHAVIOUR DEFINED AS *This action is used to dismiss a protection scheme. The protectionGroup object instance indicated in the action argument and all the contained protectionUnits are deleted. After the execution of this action all the resources previously participating in the protection scheme will operate in an unprotected mode. Yet, protectedTTPs and unprotectedCTPs will remain to allow for future participation in other protection groups. The action fails if manual or forced switch commands are active on any of the protection units. Automatic switches present before the deletion are implicitly released as a side effect. No notification is sent to report the release of automatic switches.*; establishProtection ACTION BEHAVIOUR establishProtectionBeh; MODE CONFIRMED; WITH INFORMATION SYNTAX SDHProtCoordASN1.EstablishProtectionInfo; REGISTERED AS {g774-09Action 2}; establishProtectionBeh BEHAVIOUR DEFINED AS *This action is used to create a protection scheme within a network element. When applied, one protectionGroup object instance is created. The protectionUnits field indicates the protection resources which will participate in the protection scheme and their role (protected/protecting). One protectionUnit instance is created for each element of the protectionUnits field. The unreliableResourcePointer, the protecting and the priority attributes of each protectionUnit are initialized with the value provided by the ProtectionResource sequence (priority optional). The priority must be assigned either to all protected (or protecting) units or to none. At least one protected and one protecting protection units must be provided by the managing system. The specificPUConfiguration field allows to define additional protection unit attributes for specific subclasses of the protectionUnit class. The specific parameter to be used is defined in protectionCoordinator subclasses. The optional protectionGroupType field is used to discriminate whether the protection type is 1+1 (plus) or M:N (colon). The protectionGroupType attribute of the protectionGroup object instance will be set accordingly. This field can be present only when the managing system indicated one protected and one protecting resource; if, in this case, it is absent the NE will set the protectionGroupType attribute according to its own capabilities. The optional revertiveInformation field allows the managing system to ask for a revertive/non-revertive protection scheme and, only if revertive is set to TRUE, to assign the wait-to-restore time. If the revertiveInformation is not present the NE will set the revertive and waitToRestoreTime attributes according to its own capabilities. The specificPGConfiguration field allows to define additional protection group attributes for specific subclasses of the protectionGroup class. The specific parameter to be used is defined in protectionCoordinator subclasses.*; modifyProtection ACTION BEHAVIOUR modifyProtectionBeh; MODE CONFIRMED; WITH INFORMATION SYNTAX SDHProtCoordASN1.ModifyProtectionInfo; REGISTERED AS {g774-09Action 3}; modifyProtectionBeh BEHAVIOUR DEFINED AS *This action is used to add and/or remove one or more resources from a protectionGroup. Action requests that would reduce to zero the number of protected or protecting units will be rejected. If the protectionGroupType was 1+1 (plus) and one or more protection units are added, it automatically switches to M:N (colon). The action fails if manual or forced switch commands are active on any of the protection units under removal. Automatic switches present before the deletion of a protectionUnit are implicitly released as a side effect.*; mSPConfigurationError PARAMETER CONTEXT SPECIFIC-ERROR; WITH SYNTAX SDHProtCoordASN1.MSPConfigurationError; BEHAVIOUR mSPConfigurationErrorBeh; REGISTERED AS {g774-09Parameter 1}; mSPConfigurationErrorBeh BEHAVIOUR DEFINED AS *This parameter is included in the error parameter of the CMIP APDU when the establishProtection or modifyProtection action received by the sdhMSPProtectionCoordinator fails for specific MSP configuration inconsistencies.*; mSPGroupConfigurationParameter PARAMETER CONTEXT ACTION-INFO; WITH SYNTAX SDHProtCoordASN1.MSPGroupConfigurationParameter; BEHAVIOUR mSPGroupConfigurationParameterBeh; REGISTERED AS {g774-09Parameter 2}; mSPGroupConfigurationParameterBeh BEHAVIOUR DEFINED AS *This parameter is used in the specificPGConfiguration field of the establishProtection action received by the sdhMSPProtectionCoordinator, when the establishment of a sdhMSProtectionGroup is requested by the management system. The protectionSwitchMode field indicates whether protection switching is done on a unidirectional or bidirectional basis. The aPSProtocolPresent boolean field indicates whether the K1/K2 protocol is used. The protectionMismatchStatusPkg conditional package of the sdhMSProtectionGroup object is instantiated if aPSProtocolPresent value is TRUE.*; mSPUnitConfigurationParameter PARAMETER CONTEXT ACTION-INFO; WITH SYNTAX SDHProtCoordASN1.MSPUnitConfigurationParameter; BEHAVIOUR mSPUnitConfigurationParameterBeh; REGISTERED AS {g774-09Parameter 3}; mSPUnitConfigurationParameterBeh BEHAVIOUR DEFINED AS *This parameter is used in the specificPUConfiguration field of the establishProtection or modifyProtection action received by the sdhMSPProtectionCoordinator, when the establishment or modification of a sdhMSProtectionGroup is requested by the management system. The channelNumber field indicates the channel number associated with the protection unit. The sdhPriority field indicated the priority (High/Low) of the protected protection unit. For protecting protection units this field is not present. If the extraTrafficControl field is present the extraTrafficControlPkg is instantiated in the protectionUnit object instance. The administrativeState is initialized with the value provided by this field. This field can only be present if the aPSProtocolPresent value is set to true and if the protection unit is protecting.*; protectionConfigurationError PARAMETER CONTEXT SPECIFIC-ERROR; WITH SYNTAX SDHProtCoordASN1.ProtectionConfigurationError; BEHAVIOUR protectionConfigurationErrorBeh; REGISTERED AS {g774-09Parameter 4}; protectionConfigurationErrorBeh BEHAVIOUR DEFINED AS *This parameter is included in the error parameter of the CMIP APDU when the establishProtection or modifyProtection action received by a subclass of the protectionCoordinator fails for generic configuration inconsistencies.*; removeProtectionError PARAMETER CONTEXT SPECIFIC-ERROR; WITH SYNTAX SDHProtCoordASN1.RemoveProtectionError; BEHAVIOUR removeProtectionErrorBeh; REGISTERED AS {g774-09Parameter 5}; removeProtectionErrorBeh BEHAVIOUR DEFINED AS *This parameter is included in the error parameter of the CMIP APDU when the dismissProtection or modifyProtection action received by a subclass of the protectionCoordinator fails. The operatorCommandPresent result is returned when a manual or forced switch is present in the protection group.
