This Lineman's Test Set is a new design to provide both DTMF and dial pulse output. The Lineman's Test Set features line-powered operation, so no extended power is required unless operating on low voltage or dry circuits. It is used by installers, repair technicians and other authorized personnel for line testing and temporary communications. Thepolarity LED provides immediate visual indication for Tip (+) and Ring (–) polarity.
