AppendixA Troubleshooting and Specifications
This appendix provides information on how to identify and correct some
common problems you may encounter when using and configuring the
AST510.
If the following troubleshooting tips have not resolved the problem
contact the company from which you purchased the AST510 for
assistance.
In case you encounter DSL connectivity problems due to
misconfiguration you might consider a hardware reset to factory
defaults as described in this appendix.
However, be aware that a reset to factory defaults destroys all
configurational changes you made to the AST510 internal settings.
