Table D-249	Field Descriptions for the QoS 15 Min and QoS 1 Day Subtabs
Field		Description
Errored Seconds		Sets the high threshold for the number of FEC 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 FEC severely errored seconds (SES) and the alarm
		severity level. A severely errored second is a one-second period that contains at least 30%
		errored blocks or at least one defect.
Background Block Errors		Sets the high threshold for the number of FEC 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.
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).

D.5.1.5 Action Tab

The Action tab allows you to force the ONS 15808 optical output power.

Table D-250 Field Descriptions for the Action Tab

Field	Description
Output Power Setting
Force Optical Output Power	Allows you to activate the output power control mode on the BT transponder and force the
	transponder to regulate the optical output power. An improper setting of the transponder
	output power level could affect either of the following:
	• The equalization of the channel downstream from the optical line, from the optical
	channel S/N in fiber, and at the end of the optical line.
	• The optical channel power at the end of the optical line.
	Click Execute to activate this feature.
Transparency Configuration	Allows you to activate CDL Transparency Configuration, which allows you to configure
	the preamble transparency by the BT10E-LCxx module. Click Execute to activate this
	feature.
Buffer Size Configuration	Allows you to activate the Buffer Size Configuration action, which allows you to configure
(packets)	the packet buffer size. Click Execute to activate this feature.
