| 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 loss of sync word (LOSW) defects that have occurred since the last time |
| that the G.shdsl error counters were cleared. An LOSW is indicated when three or more consecutive |
| frames contain one or more bit errors in the frame sync word. |
| • 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 |
