Module: ADSL2-LINE-MIB

OID (symbolic): ADSL2-LINE-MIB::adsl2PMChHist1DCorrectedBlocks

OID (numeric): 1.3.6.1.2.1.10.238.1.4.2.3.1.5

Node type: OBJECT-TYPE

Type: Unsigned32

Access: read-only

Description: Count of FEC (FFEC for ATU-R) anomalies (corrected code words) occurring in the channel during the interval. This parameter is inhibited during UAS or SES. If the FEC is applied over multiple channels, then each related FEC (or FFEC) anomaly should increment each of the counters related to the individual channels.

What is adsl2PMChHist1DCorrectedBlocks?

This OID tracks the count of FEC corrected code words (FFEC for ATU-R) that recovered from errors during a measurement interval on the ADSL link. Engineers use this to assess line stability and the effectiveness of forward error correction in real-time conditions. A count of 200 corrected blocks per interval suggests the line is busy auto-correcting transmission errors, indicating marginal link quality.
