DSL Line Error Counters
Five counters display how many Loss of Sync’s have occurred, CRC Errors, SEGD Errors, SEGA Errors, and Loss
of Delineation. Loss of Sync and CRC Errors are the most commonly used statistics in normal
performance evaluation.
Figure 9. DSL line error counters
• Loss of Sync: The number of times that synchronization has been lost since the error counters have
been cleared.
• CRC Errors: Shows the number of CRC errors that have occurred since either startup or the last time that
error counters were cleared.
• SEGD Errors: The number of SEGD errors in the DSL link.
• SEGA Errors: The number of SEGA errors in the DSL link.
• Loss of Delineation: The number of time that delineation has been lost.
