The operation of the physical interface is often critical in determining the cause
of network problems. Therefore, the Advisor WAN tracks errors at the physical
layer. Signal events are recorded on the display for both the line (network)
side as well as the equipment (subscriber) side.
Line status is displayed in real time (with 1 second resolution) All the events
listed below are saved in the buffer and counted in the line status display.
These events may be logged to disk. Critical parameters marked with an
asterisk (*) are also displayed in large green or red boxes in the line status
display, for easy, at-a-glance viewing.
