A read-write Unsigned32 setting the number of consecutively occurring severely errored codewords within one second required before that second is classified as a Consecutively Severely Errored Second (CSES). Because a burst of back-to-back bad codewords is more damaging than the same number scattered throughout a second, this threshold specifically captures burst-type severe impairment distinct from the plain SES metric. For example, an engineer investigating brief but intense interference bursts, rather than steady error rates, would specifically watch the CSES counter driven by this p2mpSuLinkCSESThresh setting.
