Layer 1 is established. Unplug the connector and replug
it into the same port. Rerun the test. If the problem
persists, contact the LEC.
The possible causes of this problem are:
■ The DSL is provisioned with only one active DN
(rather than two) at the CO.
■ Two lines are administered when only one line is
provided by the CO.
Check that the facilities are administered properly and
rerun the tests if you made any corrections.
