properly
Check DSL Synchronization
This test checks your DSL modem to see if it can
successfully negotiate and establish a DSL connection
with your service provider's central office equipments.
The test returns PASS if a DSL connection is
established.
If this test returns FAIL, please please try the test again
a few minutes after this test is completed. Since your
DSL modem need a couple of seconds to a few minutes
to establish the DSL connection depending on your
phone line quality. If this test returns FAIL, make sure
your phone line is connected to your DSL modem
securely , 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
ATM OAM F5 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 modem could still work even if this
test fails.
If this test fails consistently and your DSL modem
seems not working, check to make sure the VPI and VCI
are configured correctly.
This test returns FAIL if the DSL synchronization test
failed.
