    CHAPTER 4: Operation 2. Introduction Congratulations on purchasing the Voice Conferencing System. A significant step forward in the evolution of hands-free calling, the VCS provides the ultimate in clear, natural audio conferencing through any analog telephone line. 2.1 Overview With the Voice Conferencing System, you can conduct an audio conference with the interactive qualities and audio characteristics of a face-to-face meeting over an ordinary phone line.
  • Page 11 VOICE CONFERENCING SYSTEM CHAPTER 2: Introduction (1) Power-lnterface Module The power-interface module has a U.S.-standard three-prong 120-VAC power plug that can be plugged into any 110-VAC outlet.

    CHAPTER 4: Operation 2.3 The Keypad Keys and Their Functions The Voice Conferencing System has a standard dial keypad, as shown in the illustration below. (The keys that are not labeled are reserved for future use.) The keypad is “hot,” meaning that the VCS will go off hook automatically when you start dialing—you don’t have to press the ON/OFF button first.

  • Page 13: Other Features

    VOICE CONFERENCING SYSTEM CHAPTER 2: Introduction 2.4 Other Features The Voice Conferencing System has an abundance of top-of-the-line features, including: • Built-in non-bias full-duplex operation. This means that people at the remote end, especially if they are on handsets, will be able to hear what’s going on in the local room even when they are interrupted, not just when they interrupt.
  • Page 14 CHAPTER 4: Operation • 16-bit codec input and output sampling that gives you the same accurate, lifelike sound you would get from a good CD player. This level of sound quality rivals that of a face-to-face meeting and simply can’t be achieved by conference phones with 8- or 12-bit codecs.

    VOICE CONFERENCING SYSTEM 4. Operation 4.1 Placing, Answering, and Ending Calls To place a call from the Voice Conferencing System, either just begin dialing directly from the keypad or press the ON/OFF key before you dial. (The VCS goes off hook automatically when you start dialing if you haven’t already pressed the ON/OFF key.) The two LEDs on the VCS’s main module will turn from red to green, indicating that the Voice Conferencing System is off hook.

    CHAPTER 4: Operation You cannot drop the second party’s line and continue talking to the third party; you must ask the second party to hang up. (This is a limitation of the worldwide phone system, not of the VCS.) Once the second party hangs up, the third party becomes the second party, and you can add a new third party to the line if you wish.
