dot3ExtPkgOptIfLowerInputPowerThreshold

Module: DOT3-EPON-MIB

OID (symbolic): DOT3-EPON-MIB::dot3ExtPkgOptIfLowerInputPowerThreshold

OID (numeric): 1.3.6.1.2.1.155.1.4.1.5.1.5

Node type: OBJECT-TYPE

Type: Integer32

Access: read-write

Description: The lower limit threshold on input power. If dot3ExtPkgOptIfInputPower drops to this value or below, a Threshold Crossing Alert (TCA) should be sent. Reading will present the threshold value. Writing will set the value of the threshold. The write operation is not restricted in this document and can be done at any time. Changing dot3ExtPkgOptIfLowerInputPowerThreshold can lead to a Threshold Crossing Alert (TCA) being sent for the respective interface. This alert may be leading to an interruption of service for the users connected to the respective EPON interface, depending on the system action on such an alert. This object is applicable for an OLT and an ONU. At the OLT, it has a distinct value for each virtual interface.

What is dot3ExtPkgOptIfLowerInputPowerThreshold?

This read-write value sets the lower input-power alarm threshold, in 0.1 dBm units; when dot3ExtPkgOptIfInputPower drops to or below it, a Threshold Crossing Alert should be raised. Admins set this to be notified before a weakening optical signal actually causes a link outage.
