In this user interface, you can query and set clock source switching conditions, and the status of switching condition enabling.

Navigation Path

In the NE Explorer, choose Configuration > Clock > Clock Source Switching. Click the Clock Source Switching Conditions tab.

Parameter Description

Parameter	Value	Description
NE Name	For example: NE1	Displays the name of an NE.
Clock Source	For example: Internal Clock Source	Indicates the name of the clock source.
AIS Alarm	Yes, No Default: No	Sets the switching conditions enable status. When an AIS alarm occurs in the NE, the NE thinks that the corresponding clock source fails.
B1 BER Threshold-Crossing	Yes, No	Sets the switching conditions enable status. When B1 error threshold-crossing occurs in the NE, the NE thinks that the corresponding clock source fails.
CV Threshold-Crossing	Yes, No	Sets the switching conditions enable status. When CV threshold-crossing occurs in the NE, the NE thinks that the corresponding clock source fails
CV Threshold	-	Displays the CV threshold.
B2_EXC Alarm Generated	Yes, No	Sets the switching condition enable status. When B2_EXC alarm occurs in the NE, the NE thinks that the corresponding clock source fails.
R_LOS, R_LOF and R_OOF/R_LOC Alarms	Yes	Displays the switching conditions enable status. When an R_LOS, R_LOF and R_OOF/R_LOC alarm occurs in the NE, the NE thinks that the corresponding clock source fails. The defaults is Yes, and you cannot set it.
OTU1_DEG Alarm	Yes, No Default: No	Specifies the switching condition enabling status. When an OTU1_DEG alarm occurs in the NE, the NE regards that the corresponding clock source fails.
OTU2_DEG Alarm	Yes, No Default: No	Specifies the switching condition enabling status. When an OTU2_DEG alarm occurs in the NE, the NE regards that the corresponding clock source fails.
OTU3_DEG Alarm	Yes, No Default: No	Specifies the switching condition enabling status. When an OTU3_DEG alarm occurs in the NE, the NE regards that the corresponding clock source fails.
ODU2_PM_AIS Alarm	Yes, No Default: No	Specifies the switching condition enabling status. When an ODU2_PM_AIS alarm occurs in the NE, the NE regards that the corresponding clock source fails.
ODU2_PM_DEG Alarm	Yes, No Default: No	Specifies the switching condition enabling status. When an ODU2_PM_DEG alarm occurs in the NE, the NE regards that the corresponding clock source fails.
ODU3_PM_AIS Alarm	Yes, No Default: No	Specifies the switching condition enabling status. When an ODU3_PM_AIS alarm occurs in the NE, the NE regards that the corresponding clock source fails.
ODU3_PM_DEG Alarm	Yes, No Default: No	Specifies the switching condition enabling status. When an ODU3_PM_DEG alarm occurs in the NE, the NE regards that the corresponding clock source fails.
MS_AIS Alarm	Yes, No Default: No	Specifies the switching condition enable status. When an MS_AIS Alarm alarm occurs in the NE, the NE regards that the corresponding clock source fails.
B2_EXC Alarm	Yes, No Default: No	Specifies the switching condition enabling status. When an B2_EXC alarm occurs in the NE, the NE regards that the corresponding clock source fails.
