docsPnmCmtsUsImpNoiseEnable
Module: DOCS-PNM-MIB
OID (symbolic): DOCS-PNM-MIB::docsPnmCmtsUsImpNoiseEnable
OID (numeric): 1.3.6.1.4.1.4491.2.1.27.1.3.4.1.1
Node type: OBJECT-TYPE
Type: TruthValue
Access: read-write
Description: This attribute causes the CCAP to begin the collection of the configured Impulse Noise events. If the FreeRunDuration is set to a value greater than zero, the StartTriggerLevel is ignored and measurement of the signal power at the RF port begins when the Enable is set to true. The Enable attribute is cleared internally if FreeRunDuration has expired. If the FreeRunDuration is equal to zero and the Enable attribute is set to true, clearing the Enable causes the CCAP to stop the capture and generate the file of impulse noise data. If the NumEventsCounted is zero when the Enable is cleared, no file will be created.
Interaction with other table rows:
- This object returns 'inconsistentValue' if set to 'true' while the value of 'docsPnmCmtsUsImpNoiseMeasStatus' is a value of 'busy'.
- Default values are provided for read-write objects in this table; thus, this object may be set to 'true' without explicitly setting these values. However, the default values may not be appropriate and care should be taken to insure these values are correct for the desired test case.
- Setting this object to a value of 'true' will change the value of the 'docsPnmCmtsUsImpNoiseMeasStatus' to 'busy'.
What is docsPnmCmtsUsImpNoiseEnable?
Setting this 'true' starts upstream impulse-noise event collection; behavior depends on FreeRunDuration -- if nonzero, it runs for that duration ignoring the start-trigger level, otherwise it collects individual burst events until cleared, generating a file (if any events were counted) when disabled. The main on/off switch admins use to capture a log of impulse-noise bursts hitting the upstream, useful for tracking down intermittent ingress sources.
