What is aal2CpsOsfMismatchErrors?

This read-only Counter32 counts CPS-layer Offset Field mismatch errors, corresponding to errnum 2 in Table 6/I.363.2. It flags a specific class of framing inconsistency in the CPS header that suggests corrupted or misaligned packet data. An admin correlating this counter with a particular time window can narrow down when a transmission anomaly started affecting this AAL2 connection.
