of the capture file. 622Vu Advisor only displays those options that are
appropriate to the level of detail shown in the main display (PDU or cell).
4. In the Source area, indicate whether to search traffic captured on Channel 1,
Channel 2, or both.
5. Mark Search Backwards to begin searching for the specified value at the
end of the capture file; otherwise (with this box unmarked) the system starts
at the beginning of the file.
6. If you’re searching for an ASCII value, indicate whether to Match Case or
not. Leave this box blank for a non-case-sensitive search.
7. If you want to treat the Find What and/or VCC values as a bit-match pattern,
mark the Use Search String as Bit-AND Mask box. With this box marked,
622Vu Advisor interprets the Find What and/or VCC values as a bit-match
pattern, returning the first cells/PDU that match any of the ON bits in the
mask. For example, if you specify a hex 03 (binary 0000 0011) in the search
string, fixed at offset 15, the Find looks for the first cell whose payload has
either of the low-order two bits set.
8. Optionally, mark the Select Cells/PDUs NOT Matching Search Criteria
box to toggle between selecting values that match or don’t match the other
specifications. With this box marked, the select/reject decision that’s made
by taking all the other criteria into account is reversed at the very end of the
decision-making process; any cells or PDUs that would normally be rejected
are accepted, and any cells/PDUs that would normally be accepted are
rejected.
9. The Search at Fixed Offset field applies if you’re searching for a string in
the payload. It allows you to specify an offset from the beginning of the
payload where you want to begin the search. Valid offsets are in the range
1–48 for a cell-by-cell search; 1–65,535 for a PDU search. If you leave this
field blank, 622Vu Advisor searches the entire payload.
10. The Search Index Range field lets you limit the search to a particular range
of cells or PDUs, identified by the number displayed to the left of each
cell/PDU in the capture-file display. Specify a starting (i.e., low) and/or an
ending (i.e., high) number to identify the range you want to search. These
default, respectively, to the first and last cells in the capture file.
11. The Search Time Range field lets you limit the search to cells/PDUs
captured during a specific time period. Specify the from (left) and to (right)
times using an hour:minute:second format, with an optional 9 decimal
positions to the right of the seconds field: hh:mm:ss.nnnnnnnnn
