This OID controls how many error events must occur before the device raises an alarm for the DTE port frame relay management, with a range of 1 to 10. You would configure this to tune alert sensitivity on the DTE port: a low value catches problems quickly, while a higher value prevents nuisance alarms from transient errors. Setting this to 2 means any 2 errors trigger an alert (very sensitive); setting it to 8 tolerates 7 errors before alarming (less sensitive).
