Checking Circuit 0 for Network Connection
Test ATM OAM Segment Loop Back
This test sends ATM OAM F5 Segment loop back request cells to the central office
equipments through your DSL connection. This test will pass if response cell is received.
Since your service provider might not support this test, your DSL homestation could still
work even if this test fails.
If this test fails consistently and your DSL homestation seems not working, check to make
sure the VPI and VCI are configured correctly.
This test returns FAIL if the DSL synchronization test failed.
Test ATM OAM End-to-End Loop Back
This test sends ATM OAM F5 End-to-End loop back request cells to the central office
equipments through your DSL connection. This test returns PASS if response cell is received.
Since your service provider might not support this test, your DSL homestation could still
work even if this test fails.
If this test return FAIL consistently and your DSL homestation seems not working, check to
make sure the VPI and VCI are configured correctly.
This test returns SKIPPED if the DSL synchronization test failed.
Test Ethernet connect to ATM
This test returns PASS if the ATM AAL5 module is loaded correctly in your DSL homestation.
If this test returns FAIL, an internal error has occurred.
This test returns SKIPPED if the DSL synchronization does not return PASS.
Test PPPoE connection
This test returns PASS if your login name and password have passed authentication with
your service provider.
If this test returns FAIL, run this test again a few minutes after this test is completed,
especially if your PPP connection has just been improperly disconnected. If this test
consistently fails, first make sure your login name and password are correct. Remember
that login name and password are case sensitive.
This test returns SKIPPED if “PPPOE connect to Ethernet” test does not return PASS and
your DSL homestation is configured as PPPOE encapsulation.
This test also returns SKIPPED if “Ethernet connect to AAL5” test does not return PASS and
your DSL homestation is configured as PPPOA encapsulation.
