D/A - Digital to Analogue conversion
DAC - Digital to Analogue Convertor
DAMA - Demand Assigned Multiple Access
D-AMPS - Digital AMPS, a US wireless standard also known as IS-136
DAN - DECT Access Node
Data capable:
Mobile phones which have the capability to enable transmission of data from a laptop computer or PDA via the phone
Datacable : interface for conecting a mobile fone to pc
db - decibel (unit if sound)
DB - Dummy Burst; transmitted as a filler in unused timeslots of the carrier
DCT /3,4 - digital core technology
DCT/L - digital core technology linda
DCCH - Digital Control Channel
DTCH - Digital Traffic Channel
DTX - Discontinous Transmission Exchange
DCA - Dynamic Channel Assignment
DCCH - Dedicated Control Channels
( responsible for roaming, handovers, encryption etc)
DCE - Data Communications Equipment
DCH - Data Clearing House
DCPSK - Differentially Coherent Phase Shift Keying
DCS1800 - Digital Cellular System at 1800MHz, now known as GSM1800
DECT - Digitally Enhanced Cordless Telecommunications system, a second generation digital cordless technology standardised by ETSI
DEPSK - Differential Encoded Phase Shift Keying

DFSK - Double Frequency Shift Keying
Digital:
a method of representing information as numbers with discrete values; usually expressed as a sequence of bits
Digital a method of encoding a transmission that involves translating information (in the case of digital phones the information would be a voice conversation) into a series of 0’s and 1’s. Digital communications technology offers cleaner calls without the static and distortion that is common with analog phones. The majority of new handsets sold today are digital rather than analog technology.
DPCM - Differential Pulse Code Modulation
DPSK - Digital Phase Shift Keying
DQPSK - Digital Quadrature Phase Shift Keying
DS-CDMA - Direct Sequence CDMA
DSP - Digital Signal Processor
Digital Signal Processing refers to manipulating analog information, such as sound or photographs that has been converted into a digital form to improve accuracy and reliability of digital communications.
DSC- Digital Signal Controller
DSRR - Digital Short Range Radio
( a UK standard for a low power, short range radio system designed for small voice and data networks)
DTE - Data Terminal Equipment
DTMF - Dual Tone MultiFrequency;
(better know as Touch Tone. The tones generated by touching the keys on the phone are used for a variety of purposes )
DTX - Discontinuous Transmission
Dual Band:
The capability of GSM infrastructure elements and handsets to work across both the 900MHz and 1800MHz bands. The capability to seamlessly handover between the two bands offers operators major capacity gains
Duplex:
The wireless technique where one frequency band is used for traffic from the network to the subscriber (the downlink) and another, widely separated, band is used for traffic from the subscriber to the network (the uplink)
