DIAGNOSTICS
The Diagnostics menu provides feedback on the connection status of the
CPVA500 and the ADSL link. A description of each test can be obtained by
clicking on the help button associated with the test.
Without an active ADSL connection, many of the tests will not be activated, and
when the current network operating mode is in bridge, the default gateway and
DNS server tests will not be activated.
There are two buttons at the bottom of the screen:
•
Rerun Diagnostic Tests
•
Rerun Diagnostic Tests With OAM F4
When either of the Rerun Diagnostic Tests buttons are pressed, all the
diagnostic tests are repeated. Normally, if one or more tests return a failure
status, the user should rerun all the tests again to more thoroughly diagnose
the problems encountered.
When Rerun Diagnostic Tests With OAM F4 is pressed, ATM OAM F4 loopback
cells are also transmitted, in addition to OAM F5 cells. It is possible that the
ATM OAM F4 loopback or segment tests may not be supported by the ATM
devices in the DSL service provider's network. For this reason, the OAM F4 test
is separated from the general diagnostics tests. When an OAM F4 failure is
encountered, the output screen will appear as an F4 Fail.
