Field	Description
B1 Counters
Errored Seconds	Sets the high threshold for the number of B1 errored seconds (ES) and the alarm severity
	level. An errored second is a one-second period with one or more error blocks or at least
	one defect.
Severely Errored Seconds	Sets the high threshold for the number of B1 severely errored seconds (SES) and the alarm
	severity level. A severely errored second is a one-second period that contains at least 30
	percent of errored blocks or at least one defect.
Background Block Errors	Sets the high threshold for the number of B1 background block errors (BBE) and the alarm
	severity level. An errored block is a block in which one or more bits are in error. A
	background block error is an errored block that does not occur as part of a severely errored
	second.
Bit Error Rate	Sets the high threshold for the B1 bit error rate (BER) and the alarm severity level. The
	BER is the ratio of received bits that contain errors.
FEC Counters
Errored Seconds	Sets the high threshold for the number of FEC ES and the alarm severity level.
Severely Errored Seconds	Sets the high threshold for the number of FEC SES and the alarm severity level.
Background Block Errors	Sets the high threshold for the number of FEC BBE and the alarm severity level.
Unavailable Seconds	Sets the high threshold for the number of FEC unavailable seconds (UAS) and the alarm
	severity level. The detection of 10 consecutive SES begins a period of UAS. The 10 SES
	detected are part of the UAS. The ES and SES counters decrement by 10 seconds and the
	UAS counter increments by an equivalent number of seconds. A new period of available
	time begins at the onset of 10 consecutive non-SES events.
Error Corrected Rate	Sets the high threshold for the bit error corrected rate (ECR) and the alarm severity level.
	The ECR is the ratio of FEC bit errors corrected to bits transmitted.
Uncorrected Codewords Rate	Sets the high threshold for the uncorrected codeword rate (UCR) and the alarm severity
	level. The UCR is the ratio of uncorrected codewords to codewords transmitted. A
	codeword is a block of N symbols that carry K information symbols and R redundant
	symbols (N = K+R).
Unavailable Seconds	Sets the high threshold for the number of B1 unavailable seconds (UAS) and the alarm
	severity level. The detection of 10 consecutive SES begins a period of UAS. The 10 SES
	detected are part of the UAS. The ES and SES counters decrement by 10 seconds and the
	UAS counter increments by an equivalent number of seconds. A new period of available
	time begins at the onset of 10 consecutive non-SES events.
