Module: DOCS-PNM-MIB

OID (symbolic): DOCS-PNM-MIB::docsPnmCmtsUsImpNoiseCenterFrq

OID (numeric): 1.3.6.1.4.1.4491.2.1.27.1.3.4.1.5

Node type: OBJECT-TYPE

Type: Unsigned32

Access: read-write

Description: This attribute defines the center frequency for the noise power measurement.

This object cannot be changed while a capture is in progress. It will return a value of 'inconsistentValue' if set while the value of 'docsPnmCmtsUsImpNoiseMeasStatus' is set to a value of 'busy'.

What is docsPnmCmtsUsImpNoiseCenterFrq?

The center frequency, in Hz (default 7,000,000 i.e. 7 MHz), of the upstream band being monitored for impulse-noise power measurement. An admin sets this to the specific upstream frequency of interest, e.g. where a suspected ingress source is affecting service.
