User's Manual

The STATISTICS screen is displayed which contains the following information:
• Status: Indicates the sync status and the received BER pattern
• Conf. Speed: Capacity set for BER tester
• Act. Speed: Real data rate dedicated for BER (automatically adjusted data rate)
• TX Pattern: Set of BER frame type (has to be set the same on both sides)
• Bit Count: Overall transmitted bits
• Err Count: Overall error bits
• Sync Count: Number of synchronizations since the last counters clearance
• BER: Error rate
• TLE: Time since last error occurrence
• TBE: Time between last two errors
• EFS: Time of error-free traffic in seconds
• ERS: Time elapsed while the link failed in seconds
Data Evaluation:
Clear the BER tester counters and check the results by clicking Refresh button.
For proper functioning of GX800 link, the values of EFS parameter, ERR Count, Sync Count,
BER, TLE, TBE and ERS parameters should be equal to zero.
If the test results vary, and the link (line) fails, it is necessary to verify the link installation and
configuration (verification of connected user line).
For GX800 link test, the same results must be read on both sides of the link.
