Indicates that the DSL modem has detected a DSL signal
from the telephone company. A solid ADSL LED on the device
also indicates the detection of a DSL signal from the telephone

on your Internet connectivity. Therefore, if this test fails but you
are still able to access the Internet, there is no need to
