The information given on this site for getting line stats from the F5D7632 doesn't work with the latest version (using firmware 4.01.09). This version doesn't accept telnet connections, but it does support the hidden page
http://192.168.1.1/adsl_status_main.stmHowever you can't go straight to this page; you have to log into the web interface of the router in the normal way first, then go to the above address, where the stats are displayed.
