dB
Decibel. A unit used to express relative difference in power between acoustic or
electric signals, equal to ten times the common logarithm of the ratio of the two
power levels. An increase of 3 dB is equal to doubling the power; a decrease of 3
dB is equal to halving the power.
dBm
A measure of power in communications; the decibel referenced to one milliwatt
into a 600-ohm load (0 dBm = 1 milliwatt).
DCD
Data Carrier Detect. Also known as the Received Line Signal Detector (RLSD).
This signal is passed from a local modem to a local DTE when an acceptable
carrier signal is received by the modem over the telephone line.
DCE
Data Communications Equipment. A modem or other data transmission device.
Demodulation
In data communications, retrieval of an original digital data signal from a
modulated analog signal.
Digital signal
The binary 0 (off) and 1 (on) output of a data terminal. Modems convert digital
signals into analog waves for transmission over conventional telephone lines.
DSR
Data Set Ready. This signal is passed from the local modem. Indicates that the
local modem is ready to enter the data transmission phase.
DTE
Data Terminal Equipment. End user devices that generate or receive data and that
provide data communications control functions. Examples include: central
processing units (CPUs), front-end processors (FEPs), high-speed multiplexers,
PCs, user terminals, and so on.
DTMF
Dual Tone Multi-Frequency. A signaling method used for push-button telephones
that combines two output signals to create a unique tone for each of the 12 keys.
EBCDIC
Extended Binary Coded Decimal Interchange Code. A method of coding digital
signals using eight bits to generate 256 different characters.
Echo
Reflection back to the sender of a transmitted signal (as heard on telephone
circuits involving long distance, or poor transmission facilities).
EIA
Electronic Industries Association. The American electronics standards group.
