docsPnmCmDsHistEnable
Module: DOCS-PNM-MIB
OID (symbolic): DOCS-PNM-MIB::docsPnmCmDsHistEnable
OID (numeric): 1.3.6.1.4.1.4491.2.1.27.1.2.9.1.1
Node type: OBJECT-TYPE
Type: TruthValue
Access: read-write
Description: Setting this object to a value of 'true' instructs the CM to begin collection of histogram data and when enabled, the CM continues producing new data at its own rate.
Setting this object to a value of 'false' instructs the CM to stop the collection of histogram data.
This object returns 'true' if the CM is actively collecting histogram data. Otherwise it returns 'false'.
A restart may be accomplished by setting this attribute to 'false' and then back to 'true'.
Interaction with other table rows:
- This object is subject to the rules specified by the 'docsPnmCmCtlStatus' object. Therefore this object returns 'inconsistentValue' if set to 'true' while the value of 'docsPnmCmCtlStatus' is any value other than 'ready'.
- This object returns 'inconsistentValue' if set to 'true' while the CM is in DOCSIS Light Sleep (DLS) mode or the CM is in battery-backup mode.
- Setting this object to a value of 'true' will change the value of the 'docsPnmCmDsHistMeasStatus' to 'busy'.
What is docsPnmCmDsHistEnable?
Setting this 'true' starts downstream amplitude-histogram data collection, which continues at the CM's own rate until stopped; toggling false then true again restarts collection. Used to characterize the statistical distribution of received signal levels over time, useful for spotting impulse noise or level instability.
