Goldtool Linemans Test Set -to provide both DTMF (touch tone) and dial pulse output-Talk/Ring/Monitor tests function

Product Overview
The GoldTool TCT-1900-RD Lineman' s Test Set is a new design to provide both DTMF ( touch tone) and dial pulse output. It features line-powered operation, so no extended power is required unless operating on low voltage or dry circuits
Highlights
•Offer the latest in integrated circuit design, provide the industry standard packed with popular features. 
•Talk/Ring/Monitor three kind of tests function, its switch located on inside of handgrip. 
•Switchable tone or pulse dialling. TONE/PULSE switch are located on inside of handgrip. 
•The Hi impedance monitor will not disturb data, conversation, or signalling. 
•LED indicates reversed polarity. 
•Last number redial(31 digits maximum).
