D.5.13.3 Quality of Service Tab
The Quality of Service tab allows you to assign thresholds and alarm severities for B1 and forward error
correction (FEC) counters. Click the 15 min radio button to assign thresholds for 15-minute collection
increments. Click the 1 day radio button to assign thresholds for 24-hour collection increments.
SCC Number Displays the version of the module serial communication controller (SCC).
Product Option Displays the product option. Displays “Not Available” if the TL1 Agent version is earlier than
version 2.1.
Hardware Version Displays the version of the hardware. Displays “Not Available” if the TL1 Agent version is earlier
than version 2.1.
Line Direction Shows the line direction for the receive transponder.
State Allows you to place the receive transponder in one of two states: In Service or Under Maintenance.
PM Collection Status Allows you to enable or disable PM data collection for the receive transponder.

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.
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.
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.
