Side Restrictions - Side Restriction means that the analyzer
looks for a pattern coming wholly from the DTE or DCE side. If you
choose to search without regard for data origin, the analyzer looks
for a pattern coming from one or both sides. For example, if you
choose to search for the pattern ABC and you choose to search
without regard for data origin, the analyzer finds all three instances
of ABC shown here.
The first pattern, with the A and the C coming from the DTE device
and the B coming from the DCE is a good example of how using a
side restriction differs from searching without regard to data origin.
While searching without regard for data origin finds all three
patterns, searching using a side restriction never finds the first
pattern, because it does not come wholly from one side or the
other.
If you choose to search for the pattern ABC, and you restrict the
search to just the DTE side, the analyzer finds the following pattern:
In this example, the analyzer finds only the second pattern
(highlighted above) because we restricted the search to just the
DTE side. The first pattern doesn't qualify because it is split between
the DTE and DCE sides, and the third pattern, though whole, comes
from just the DCE side.
If we choose both the DTE and the DCE sides in the above example,
then the analyzer finds the second pattern followed by the third
pattern, but not the first pattern. This is because each side has one
instance in which the whole pattern can be found. The analyzer
completely searches the DTE side first, followed by the DCE side.
Note: Side Restriction is available for pattern and error searching.
1. Select one of the two options.
2. Select DTE, DCE, or both.
3. When you made your selections, click on the Find Next or Find Previous buttons to start the search
from the current event.
The result of the search is displayed in the Decode pane in Frame Display.
