View G.shdsl Error Counters
Step		Action
1	From the G.SHDSL Statistic Menu, enter 2 to display the G.SHDSL Error Counters menu (Figure A-19).
		Figure A-19. G.SHDSL Error Counters
2	View the current statistics, as described below:
	• CRC Error
		Indicates the total number of cyclic redundancy check (CRC) errors that have occurred on the
		G.shdsl connection since the last time that the G.shdsl error counters were cleared. CRC is an error
		checking technique used to ensure the integrity of data during transmission.
	• LOSW Errors
		Indicates the total number of cyclic redundancy check (CRC) errors that have occurred on the
		G.shdsl connection since the last time that the G.shdsl error counters were cleared. CRC is an error
		checking technique used to ensure the integrity of data during transmission.
	• Errored Seconds
		Indicates the total number of seconds in which one or more CRC errors occurred since the last time
		that the G.shdsl error counters were cleared.
	• Severely Errored Seconds
		Indicates the total number of seconds in which 50 or more CRC errors occurred since the last time
		that the G.shdsl error counters were cleared.
	• Unavailable Seconds
		Indicates the total number of seconds that the G.shdsl connection has been non-operational due to
		loss of synchronization or excessive errors since the last time that the G.shdsl error counters were
		cleared.
3	Click one of the following:
	•	Clear—resets all the counters to zero.
	•	Refresh—updates the page with current error counts.
