AlliedView NMS Administration Guide
Note: The ability for the iMAP to run DELT is from release 9.0, while the NMS DELT feature is for NMS release 10.0. Therefore,
this NMS feature can be run on an iMAP running a 9.0 load, although there are some additional DELT feature for iMAP 10.0.
12.3.1 Accessing DELT
From the Port Management application select an active ADSL port one of the supported card types. Select the ADSL
Configuration tab, then the Diagnostics tab. If the tab is not present then the port does not support DELT. Then select the
DELT tab, as shown in the following figure. If there is existing data from a previous DELT the fields are populated and the
DELT Graph tab will be active. If there was no previous DELT the DELT Graph tab will be inactive and grayed out.

12.3.2 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.
12.3.3 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.
12.3.4 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
