49250 PhoneDemo II
Model 49250 PhoneDemo II™

The Proctor Model 49250 PhoneDemo II™ demonstrates a wide variety of telecommunications products and software, such as FAX, PC/modems, feature phones, cordless phones, voice mail systems and answering machines. It allows users to make a thorough evaluation of product features by providing precision dial, ring-back, and busy tones, and by enabling authentic dialing, ringing, and data transmission functions. Because Phone Demo II is portable and doesn't require any special Telco phone lines, it can be used for product training at trade shows and customer premises as well as retail sales demonstrations. The 49250 can even be used for product testing and troubleshooting.

How It Works

49250 Schematic

The 49250 works just like a miniaturized Telco central office. It provides -48Vdc line feed, 20 Hz ringing generation, DTMF dialing detection, and precision call progress tones. The user simply plugs the demo unit into the nearest standard AC outlet, plugs in the line cords of the two telephone devices, and dials up one of the devices. Once the other device answers and a talk/data path is established, the demonstration can proceed.
