Diagnostic Test
The
Diagnostic Test
page shows the test results for the connectivity of the physical
layer and protocol layer for both LAN and WAN sides. This page will continually
refresh every 2 seconds until all tests are complete.
Testing Ethernet LAN Connection:
This test passes if the Ethernet LAN interface is
working properly.
Testing ADSL Synchronization:
This test checks your ADSL Bridge/Router to see if
it can successfully negotiate and establish an ADSL connection with your service
provider.
The test returns PASS if an ADSL connection is established.
If this test returns FAIL,
please try the test again a few minutes after this test is completed. Your ADSL
bridge/Router needs up to one minute to establish the ADSL connection depending on
your phone line quality. If this test returns FAIL, make sure your phone line is
connected to your ADSL Bridge/Router secured, and also check with your service
provider to see if your service is activated. If this test returns FAIL, all other tests will
be skipped.
Test ATM OAM Segment Loop Back:
This test sends ATM OAM F5 Segment loop
back request cells to the CO. This test will pass if a response cell is received. Since
some service providers might not support this test, it could still work even if this test
fails. If this test fails consistently and the ADSL Bridge/Router seems not working,
make sure the VPI and VCI are configured correctly. This test returns FAIL if the
ADSL synchronization test failed.
