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 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.
Test ATM OAM End-to-End Loop Back

This test returns SKIPPED if “PPPPOE connect to Ethernet” test does not return PASS and
your DSL modem is configured as PPPOE encapsulation. This test also returns SKIPPED
if “Ethernet connect to AAL5” test does not return PASS and your DSL modem is configured
as PPPOA encapsulation.
Test PPP Layer connection
This test returns PASS if your DSL modem has been assigned a valid IP address by your
service provider through DHCP or your DSL modem is assigned a valid IP address statically.
