ADSLM (ADSL Monitor) is designed to be a troubleshooting tool to help ADSL subscribers identify and understand the characteristics and personality of adsl lines. ADSLM is so versatile that it can be configured to be used in a wide variety of adslm modems and routers. Simple user interface and configuration makes ADSLM easy to use with powerful line statistics monitoring and logging.

I dont think this software is still being developed.
