sccpAccessPoint MANAGED OBJECT CLASS

"The sap2Address attribute contains the address of the sccpAccessPoint. The address contains the SubSystem Number (SSN). The sap2Address is of type SET OF OCTETSTRING. For sccpAccessPoints, the set size is 1. The sapId attribute is used in naming instances of the sccpAccessPoint managed object class.
The userEntityNames attribute contains the distinguished names of the managed objects that represent the user entities that are using the sccpAccessPoint, i.e. instances of the SCCP subsystem. The providerEntityNames attribute contains the distinguished names of the managed objects that represent the provider entities that are supporting the sccpAccessPoint, i.e. the instance of the SCCP.
The status of the sccpAccessPoint is represented by the availability status attribute. A subsystem can have the status:
? allowed, the sccpAccessPoint is reachable and is functioning normally
(availability status = available)
? prohibited, the sccpAccessPoint not reachable
(availability status = unavailable)
? congested (availability status = degraded)
The optional (national network provider option) ssAvailableAfterSpRestart attribute holds the default subsystem status as described in the procedure of 5.2.3/Q.714.
The concernedAreaPointer specifies the concerned area to be used by SCCP Management for primary broadcast in case this access point is local. In case of a remote access point, the pointed concerned area will be used by SCCP Management for the secondary broadcast. The concernedAreaPointer has value NULL if no concerned area is pointed at.
The sccpLinkagePointer specifies the sccpLinkage that is associated with remote sccpAccessPoints only. In case of a local sccpAccessPoint, the sccpLinkagePointer has value NULL. A remote sccpAccessPoint cannot be created without a valid pointer to an sccpLinkage.
The qualityofServiceAlarm can have the following probable cause:
ProbableCause = TooLargeForSegmentation which represents measurement Q.752/7.14 (PerceivedSeverity = Major/Minor/Warning).
ProbableCause = subsystemProhibited which represents measurement Q.752/8.11 and Q.752/8.12 (PerceivedSeverity = Major/Minor/Warning/Cleared).
The communicationsAlarm can have the following probable causes:
ProbableCause = sccpCongested which represents measurement Q.752/8.8
(PerceivedSeverity = Major/Minor/Warning). The congestion level is given as a parameter of the notification.
ProbableCause = localSubsystemProhibited which represents measurements Q.752/8.9 and Q.752/8.10 (PerceivedSeverity = Major/Minor/Warning/Cleared)";;
