adsl2PMChCurr15MCodingViolations
Module: ADSL2-LINE-MIB
OID (symbolic): ADSL2-LINE-MIB::adsl2PMChCurr15MCodingViolations
OID (numeric): 1.3.6.1.2.1.10.238.1.4.2.1.1.5
Node type: OBJECT-TYPE
Type: Unsigned32
Access: read-only
Description: Count of CRC-8 (FEBE for ATU-R) anomalies occurring in the channel during the interval. This parameter is inhibited during UAS or SES. If the CRC is applied over multiple channels, then each related CRC-8 (or FEBE) anomaly should increment each of the counters related to the individual channels.
What is adsl2PMChCurr15MCodingViolations?
This OID tallies CRC-8 (or FEBE for the downstream direction) checksum errors that appear in the ADSL channel data during the current 15-minute interval, counted only when the line is not in an unavailable state. These errors mean data frames arrived corrupted and had to be retransmitted, directly impacting throughput and reliability. For example, if this count reaches 100 in a 15-minute period, it indicates the line quality is degrading and might need line balancing or investigation for noise.
