TableD-249 Field Descriptions for the QoS 15 Min and QoS 1 Day Subtabs
Field Description
Errored Seconds Sets the highthreshold forthe numberof FECerrored 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 Setsthe high thresholdfor the number of FEC severelyerrored 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 thehigh threshold forthe number ofFEC background blockerrors (BBE) andthe 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 severelyerrored
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
UAScounter increments by an equivalent number of seconds. A new period of availabletime
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 carryK information symbols and R redundant symbols (N =
K+R).

Field Description
Output Power Setting
Force Optical Output Power Allows youto activate theoutput power control mode on the BTtransponder 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.

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
(packets) Allowsyou to activate the Buffer Size Configuration action, which allowsyou to configure
the packet buffer size. ClickExecute to activate this feature.
