    Congratulations! You have just purchased the Sportster Voice faxmodem. Since 1976, U.S. Robotics has grown to become a key manufacturer and developer of information access technology. U.S. Robotics' advanced technology allows you to use your faxmodem to open up a new world of information access. As an innovator in the data communications field, U.S.
  • Page 5 A modem is a computer peripheral that allows you to connect and communicate with other computers via telephone lines. Modems allow you to combine the power of your computer with the global reach of the telephone system. Because ordinary telephone lines cannot carry digital information, a modem changes the digital data from your computer into analog data, a format that can be carried.
  • Page 6 Data Communications Your modem offers a range of internationally accepted standard modulation methods and protocols. It utilizes hardware-based V.42/MNP 2-4 error control and V.42 bis/ MNP 5 data compression. Your modem will transmit at speeds up to 33.600 bps with throughput to 115.200 bps. Also, it is universally compatible with the following standards: V.34, V.FC, V.32 bis, V.32, V.22 bis, Bell 212A/V.22, V.23, V.25 and Bell 103/V.21 modems.
  • Page 7 Speakerphone You can use your new Sportster as a full-duplex speakerphone without the echoing sound of some speakerphones. The full-duplex feature allows you to speak at the same time as someone on the other end without losing any sound quality. This affords you all the convenience of a speakerphone without the extra hardware and cords for the home or office.

Analog Loopback A modem self-test in which data from the keyboard or an internal test pattern is sent to the modem's transmitter, modulated into analog form, looped back to the receiver, and demodulated into digital form.

  • Page 27: S-Registers

    Asynchronous Transmission Data transmission in which the length of time between transmitted characters may vary. Because the time lapses between transmitted characters are not uniform, the receiving modem must be signaled as to when the data bits of a character begin and when they end. The addition of Start and Stop bits to each character serves this purpose. Auto Answer Sets the modem to pick up the phone line when it detects a certain number of rings.
  • Page 28 Byte A group of binary digits stored and operated upon as a unit. A byte may have a coded value equal to a character in the ASCII code (letters, numbers) or have some other value meaningful to the computer. In user documentation, the term usually refers to 8-bit units or characters.
  • Page 29 Data Compression Table A table containing values assigned for each character during a call under MNP5 data compression. Default values in the table are continually altered and built during each call: the longer the table, the more efficient throughput gained.
