This means that the DSL line is trying to train but for some reason it cannot
establish a valid connection. A possible cause of this is that you are too far away
from the central office. Contact your DSL service provider for further assistance.

1. Make sure you have DSL service. You should receive notification from your
ISP that DSL service is installed. You can usually tell if the service is installed
by listening to the phone line: you will hear some high-pitched noise. If you do
not hear high-pitched noise, contact your ISP.
2. Verify that the phone line is connected directly to the wall and to the line input
on the modem. If the phone line is connected to the phone side of the modem
or you have a splitter installed on the phone line, the Status LED will not come
on.
