Test Screen
The following tests can be run:
Test Menu/Echo Request
Write security: 4, Read security: 5
When activated, the echo request test will begin sending continuous PPP echo
request packets to any open LCP ports. Results are displayed on the screen.
At least one PPP session must be up.
Test Menu/Dial Self
Write security: 4, Read security: 5
The dial self-test can be activated to check the ISDN parameters set under the
Configuration/WAN/ISDN
menu. This test starts the Express XL/XLT dial-
ing itself using the configured LDN numbers. Once a connection is estab-
lished, it will send PPP echo request until the test is terminated. Any error or
success messages will appear on the screen.
