Explanation

A lineman's handset (also called a buttset) can be clipped directly onto a phone line pair at any punch-down block or terminal. By listening to the line, a technician can hear the high-pitched carrier noise that DSL signals produce, confirming whether a DSL signal is present on a line that should be carrying only analog voice/fax traffic. A multimeter measures voltage/resistance but cannot identify DSL signal characteristics. A cable tester checks network cable wiring. A toner probe traces cable runs and cannot diagnose DSL signal presence.
