Step #5 - Making the ADSL connection. Plug the ADSL cable into the ADSL RJ-21 Connector on the
AT-NT117 or AT-NT118. Verify the ADSL connection via the LNK LED on the front of the unit; a blinking
LNK LED indicates that traffic is being received from the ADSL line.
Note: The distance of the copper cable between the Mini-DSLAM and the ADSL Modem will affect
the linking of the ADSL connection. If the distance is greater than a particular speed will support,
the units will not link up.
