5.7.3.3 Initiate a DELT Diagnostic
Clicking the Diagnose Interface button will initiate a DELT. A confirmation dialog box appears indicating that service may
be disrupted, if confirmed the ATI activity dialog appears until the test starts. While running, all the buttons are disabled
except for View Exported Test. The “DELT Status” field indicates “Running” or “In Progress” while the test is running.
When successfully completed the basic result values will populate the fields, the DELT Graph tab will be activated, and all
the buttons will be enabled.
5.7.3.4 Retrieve DELT Results
DELT results are automatically retrieved when the DELT tab is selected, and after a successful DELT test. Clicking the
Refresh Data button will re-retrieve this data, along with the current mode of the port. If the port Mode is unknown, due to
the port retraining after the last test, this will also update that field.
5.7.3.5 Graph DELT Result
When DELT results exist the DELT Graph tab is activated. Selecting it will display the following screen. Initially all
parameters are in the left window and none are graphed. Selecting one or more and clicking the View Parameter button
will move it into the right “Graphed Parameters” list and draw a graph of its data. The color of the line used is shown next to
the graphed parameter name. (To remove a parameter, select one or more in the “Graphed Parameters” list and click the
Remove Parameter button.
The same parameters are available for both upstream and downstream directions, though different numbers of sub carriers
are available based on the actual mode of the port. Selecting a different direction will clear the graph, move all parameters
back the available list, and switch the data to the selected direction.
Clicking the Refresh Data button will recollect the data from the iMAP just as it does on the DELT tab. This will only have
an effect if the mode of the port changes or if a new DELT was run, or the results cleared, outside of the NMS.
