Press the 

Down Arrow

 key to move the 

Time Stamp

 option to the selection line:

  CELL CAPTURE
  Store Payload       OFF
  Time Stamp           REL
  - - - - - - - - - - - - - - - - - - - - - - - 

za097f.eps

 

The 

Time Stamp

 option determines whether the OC3port Plus records the

arrival time between captured cells and how that arrival time is calculated. The
option has three settings:

•

 

REL 

Records each cell’s arrival time relative to the time that the
previous cell that was captured.

•

 

OFF 

Does not record the arrival time between captured cells.

•

 

ABS 

Stores the absolute arrival time (uses zero as the reference
point) of each cell from the time the cell capture began.

 

16. Press the 

Left

 or 

Right Arrow

 key to set a value for the 

Time Stamp

 option. The

setup is completed. The OC3port Plus is now configured for capturing ILMI
cells.

Starting an ILMI Cell Capture

 

To start the cell capture, follow the steps under "Starting a Cell Capture" earlier in
this chapter.

Looking at Captured ILMI Cells

 

For a description of the information stored on the captured cells, see "Looking at
the Captured Cells" earlier in this chapter. To view results from the last cell
capture you conducted since you turned on the OC3port Plus, see "Displaying the
Results of the Previous Cell Capture" earlier in this chapter.
