Explanation

A buttset (butt set or lineman's handset) is the correct tool for troubleshooting analog phone lines. It clips directly onto a phone line pair and allows the technician to listen for a dial tone, place test calls, and verify line quality - essential for diagnosing fax machine issues on an analog line. A cable tester verifies structured network cabling (e.g., Cat5/6). A toner probe traces cable runs through walls. A cable certifier measures whether a network cable meets performance standards like TIA-568.
