accIsdnxStatLapdN201Errors
Module: ACC-ISDN
OID (symbolic): ACC-ISDN::accIsdnxStatLapdN201Errors
OID (numeric): 1.3.6.1.4.1.5.1.1.36.7.1.18

Description: The number of LAPD frames received which contained and information field which exceeded N201.
What is accIsdnxStatLapdN201Errors?
This counter increments when LAPD frames arrive with information fields that exceed the N201 size limit (typically 260 octets), violating the protocol. These oversized frames are discarded because they cannot be processed as valid ISDN signaling. If you see this error, either the remote side is malformed or your interface received corrupted length indicators.
