connection.
Testing ADSL Synchronization: This test checks the ADSL showtime. If this test returns
FAIL, all other tests will be skipped.

loop-back request cells to the CO. This test will pass if response cell is received. Some
service providers might not support this test. If this test return FAIL consistently and the
