:HOFRPH WR WKH :RUOG RI ,QIRUPDWLRQ $FFHVV 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.
)HDWXUHV 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.
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. External modems have built-in microphones and you can attach a microphone and speaker to the internal models.

*ORVVDU\ Cross references are printed in boldface. Cross references with items in the Command Summary chapter are printed in italics. 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. Analog Signals A variety of signals and wavelengths that can be transmitted over communications lines such as the sound of a voice over the phone line.
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. See S-register (S0) in Technical Quick Reference.
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. 1 kilobyte (Kbyte) is equal to 1.024 bytes or characters; 640 Kbytes indicates 655.360 bytes or characters. Carrier A tone signifying a connection the modem can alter to communicate data across telephone lines.
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. Data Mode The mode in which the fax modem is capable of sending and receiving data files. A standard modem without fax capabilities is always in data mode.
DTE Data Terminal (or Terminating) Equipment. A computer that generates or is the final destination of data. Duplex Indicates a communications channel capable of carrying signals in both directions. See Half Duplex, Full Duplex. EIA Electronic Industries Association, which defines electronic standards in the U.S. Error Control Various techniques that check the reliability of characters (parity) or blocks of data. V.
Half Duplex Signal flow in both directions, but only one way at a time. In microcomputer communications, may refer to activation of the online Local Echo, which causes the modem to send a copy of the transmitted data to the screen of the sending computer. Hz Hertz, a frequency measurement unit used internationally to indicate one cycle per second. ITU-T An international organization that defines standards for telegraphic and telephone equipment.
Nonvolatile Memory (NVRAM) User-programmable random access memory whose data is retained when power is turned off. On the Sportster, it includes four stored phone numbers and the modem settings. OFF/ON Hook Modem operations that are the equivalent of manually lifting a phone receiver (taking it off-hook) and replacing it (going on-hook).
Remote Digital Loopback A test that checks the phone link and a remote modem's transmitter and receiver. Remote Echo A copy of the data received by the remote system, returned to the sending system, and displayed on the screen. Remote echoing is a function of the remote system. ROM Read Only Memory. Permanent memory, not user-programmable. Serial Transmission The consecutive flow of data in a single channel. Compare to parallel transmissions where data flows simultaneously in multiple channels.
V.17 Fax A ITU-T standard for making facsimile connections at 14.400 bps, 12.000 bps, 9.600 bps, 7.200 bps. V.21 A ITU-T standard for modems operating in asynchronous mode at speeds up to 300 bps, full-duplex, on public switched telephone networks. V.22 A ITU-T standard for modem communications at 1200 bps, compatible with the Bell 212A standard observed in the U.S. and Canada. V.22 bis A ITU-T standard for modem communications at 2400 bps.
V.42 A ITU-T standard for modem communications that defines a two-stage process of detection and negotiation for LAPM error control. V.42 bis An extension of ITU-T V.42 that defines a specific data compression scheme for use during V.42 connections. Xmodem The first of a family of error control software protocols used to transfer files between modems. These protocols are in the public domain and are available from many bulletin board services.
