Hi friend.
You can log in to the device to view the DSL information, view the DSL synchronization status, or restart the DSL.
The procedure is as follows:
In the navigation tree, choose Maintain > System Information > DSL Information. In the pane on the right, you can view the DSL information, as shown in the following figure.

NOTE: If you need to renegotiate the DSL line parameters, click Restart DSL.
Since the DG8045 is a carrier product, if the problem persists, contact your local ISP for assistance.
Thanks.
