Network Tests

Network tests are used to control the activation of loopbacks
and the initiation of data test patterns.

The network tests are run on the network interface (NI).
Three different test configurations can be selected to
determine the type of loopback and the pattern to run. Test
results are displayed in the LCD window. See Figure 7-2.

Figure 7-2. Local Loopback Screen

LOCAL LOOPBCK

There are three available choices for setting the local
loopback:

No Loopback

Deactivates the loopback.

Line On

Payload On

Activates the payload loopback.
