Descriptions

specificPhysicalInstance — ETSI published formal attachments

This parameter is included in the additional info parameters of the protection switching reporting notification. This notification is sent by the protection group according to the following rules. There are several cases: The switch from protected to protecting or protecting to protected has been done without preempting an existing switch. In this case the old and new values of the Protection Status attribute of the protecting channel shall be reported in the notification by means of the oldProtectionStatus and newProtectionStatus parameters respectively. A switch is perfomed by preemting an existing one. In this case the old and new values of the Protection Status attribute of the protecting unit shall be reported in the notification by means of the oldProtectionStatus and newProtectionStatus parameters respectively. An autoswitch condition exists on an equipment but the auto-switch cannot be served due to the unavailability of the equipment that otherwise protects it. In this case the oldProtectionStatus and newProtectionStatus parameters refer to the protection status attribute value of the equipment on which the autoswitch condition arises. The exception is when the equipment is already forced or locked out, in which case no notification is sent. A working equipment (protected unit) has been locked out or released from lockout without modifying any existing switch. In this case the oldProtectionStatus and newProtectionStatus parameters refer to the protection status attribute value of the working equipment which has been locked out. A protection equipment (protecting unit) has been lockout or released from lockout without modifying the existing switch. In this case the oldProtectionStatus and newProtectionStatus parameters refer to the protection status attribute value of the protection equipment which has been lockout. The protectionSwitchReporting is not sent when the automatic switch condition is toggling between the equipment failure and WTR condition. While in the lockout of forced switch state no notification is sent except for ending of release failure.
