Error Detection Set Up
Overview
The GB1400 Analyzer calculates error results using three different methods:
Window, Test, and Totalize. These three methods are independent of each other
and can operate simultaneously. Window results are used to view current or
"real-time" performance. Totalize results are generally used to view performance
over long intervals. Test results are used to measure error performance over
specified time intervals.
Two results are calculated for all three methods:
BER
Bit Errors
In addition, Test results include the following network performance parameters
and event counts:
Test seconds
Total bits monitored
Errored seconds
Severely errored seconds
Unavailable seconds
Threshold errored seconds
Error-free seconds
Degraded minutes
Signal loss seconds
Pattern Synchronization loss seconds
Phase error seconds
For explanations of these results see Result Definitions later in this chapter.
