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.
DCE
Data Communications (or Circuit-Terminating) Equipment, such as dial-up modems that establish and control the
data link via the telephone network.
Default
Any setting assumed, at startup or reset, by the computer's software and attached devices, and operational until
changed by the user or 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.
Digital Loopback
A test that checks the modem's RS-232 interface and the cable that connects the terminal or computer and the
modem. The modem receives data (in the form of digital signals) from the computer or terminal, and immediately
returns the data to the screen for verification.
Digital Signals
Discrete, uniform signals. In this manual, the term refers to the binary digits 0 and 1. Contrast with analog
signals.
