GLOSSARY Cross references are printed in boldface. Cross references to items also found in the “Technical Quick Reference” 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, turned into analog form, looped back to the receiver, and converted back into digital form.
GLOSSARY asynchronous transmission Data transmission in which the length of time between transmitted characters may vary. Because characters may not be transmitted at set intervals, start/stop bits are used to mark the beginning and end of each character. baud rate A term used to measure the speed of an analog transmission from one point to another. Although not technically accurate, baud rate is commonly used to mean bit rate.
GLOSSARY bits per second (bps) The bits (binary digits) per second rate. Thousands of bits per second are expressed as kilobits per second (kbps). buffer A temporary memory area used as storage during input and output operations. An example is the modem's command buffer. byte A group of binary digits stored and operated upon as a unit. Most often the term refers to 8bit units or characters. One kilobyte (KB) is equal to 1,024 bytes or characters; 640 KB is equal to 655,360 bytes or characters.
GLOSSARY class 1 and 2.0 International standards used by fax application programs and faxmodems for sending and receiving faxes. cyclic redundancy checking (CRC) An error-detection technique consisting of a test performed on each block or frame of data by both sending and receiving modems. The sending modem inserts the results of its tests in each data block in the form of a CRC code.
GLOSSARY default Any setting assumed, at startup or reset, by the computer's software and attached devices. The computer or software will use these settings until changed by the user or other software. detect phase In the ITU-T V.42 error-control protocol, the first stage in establishing if both modems attempting to connect have V.42 capability. dictionary The term used for compression codes built by the V.42 bis data compression algorithm.
GLOSSARY duplex Indicates a communications channel capable of carrying signals in both directions. See half duplex, full duplex. Electronic Industries Association (EIA) Group which defines electronic standards in the U.S. error control Various techniques that check the reliability of characters (parity) or blocks of data. V.42 and MNP error-control protocols use error detection (CRC) and retransmission of flawed frames (ARQ).
GLOSSARY full duplex Signals can flow in both directions at the same time over one line. In microcomputer communications, may refer to the suppression of the online local echo. half duplex Signals can 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.
GLOSSARY local echo A modem feature that enables the modem to display keyboard commands and transmitted data on the screen. See command En. MNP Microcom Networking Protocol, an errorcontrol protocol developed by Microcom, Inc., and now in the public domain. There are several different MNP protocols, but the most commonly used one ensures error-free transmission through error detection (CRC) and retransmission of flawed frames.
GLOSSARY online fall back/fall forward A feature that allows high-speed, error-control modems to monitor line quality and fall back to the next lower speed in a defined range if line quality diminishes. As line conditions improve, the modems switch up to the next higher speed. originate mode The mode used by your modem when initiating an outgoing call to a destination modem. The transmit/receive frequencies are the reverse of the called modem, which is in answer mode.
GLOSSARY RAM Random Access Memory. Memory that is available for use when the modem is turned on, but that clears of all information when the power is turned off. The modem's RAM holds the current operational settings, a flow control buffer, and a command buffer. 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.
GLOSSARY terminal A device whose keyboard and display are used for sending and receiving data over a communications link. Differs from a microcomputer or a mainframe in that it has little or no internal processing capabilities. terminal mode Software mode that allows direct communication with the modem. Also known as command mode. throughput The amount of actual user data transmitted per second without the overhead of protocol information such as start/stop bits or frame headers and trailers.
GLOSSARY V.22 An 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 An ITU-T standard for modem communications at 2400 bps. The standard includes an automatic link negotiation fallback to 1200 bps and compatibility with Bell 212A/V.22 modems. V.27 ter An ITU-T standard for facsimile operations that specifies modulation at 4800 bps, with fallback to 2400 bps. V.
GLOSSARY V.34 An ITU-T standard that currently allows data rates as high as 28,800 bps. V.34+ An enhancement to V.34 that enables data transfer rates as high as 33,600 bps. V.42 An 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.
