
The Line column shows the number of the packet in the current capture, starting
from zero for the first packet. This number does not change, even if a display filter
is applied.

The min:sec:ms:us:ns column shows the packet’s timestamp, relative to the instant
when the capture started.

The D/U column shows the direction of the packet.

The Content column shows a brief description of the messages and/or data carried
in the packet.

For other than OMCI messages the information shown in the Content column always
starts with a frame index between brackets (i). This frame index, ranging from 0 to 7,
allows the user to match downstream frames with the corresponding upstream bursts.
The background colour of each line also facilitates this pairing.
In the downstream direction, where each line represents a downstream frame, the
content column will show when a particular frame includes a bandwidth map (BWMAP)
and/or a PLOAM message (PLOAMd), specifying the type of message. Bandwidth
maps which correspond to Serial number requests or Range requests are also
identified (SNReq and RangeReq).
In the upstream direction, where each line represents an upstream burst, the content
column shows the ONT-ID of the ONT who transmitted the burst (ONT: X). It also
shows when a particular burst includes a PLOAM message (PLOAMu), specifying the
type of message, and/or a DBRu report. When the content column of an upstream
burst shows uLOSB it means a burst was expected but no optical signal was received.
When the content column of an upstream burst shows uLOFB it means a burst was
expected and there was optical signal in the line, but the delimiter was not found.
For OMCI messages the information shown in the Content column always starts with
the ONT-ID of the ONT the message is addressed to (downstream direction) or which
