Errors

The Errors indicators at the bottom of the SONET/SDH Statistics window show the status of the SONET link as reported by the monitored interface, by indicating whether the link has experienced Loss of Pointer, Loss of Signal, or Loss of Frame defects or failures during the current 15-minute interval.

Note that Loss of Pointer is detected at the Path level on the SONET link, meaning that the error occurred anywhere on the end-to-end link between the connected FE100-Sx or APIM-2x devices that are customer premises equipment (CPE), and Loss of Signal and Loss of Frame are detected at the Section level, meaning that the error occurred on the SONET section between the monitored CPE device and the ADM node (line-terminating equipmentÑLTE) to which it is connected.
