Term Stands For.... Meaning
CD
1
Compact Disk or
2
Change Directory
1
An optical disk capable of storing large amounts of data (700x
floppy disk). It can be inserted into most pc’s and “read” to
load files onto a computer
2
A software programming term in
“C” language that tells the computer to go to a different
location in the computer’s memory.
CDMA Code Division Multiple Access Digital cellular technology that uses a spread-spectrum
technique where individual conversations are encoded with a
random digital sequence. Increases capacity and speed of
communications messages between mobile units over other
types of wireless networks.
CD-ROM Compact Disk - Read Only Memory See “CD.” If a CD is not Read Only, computers can write data
to it with that capability.
CHP Channel Processor Card A card in the digital shelf of the BTS that performs the first
stage of signal processing for up to 4 antennae. One Navini 2.4
GHz BTS has 8 antennae. The card performs digital-to-analog
conversion (DAC) and analog-to-digital conversion (ADC) for
up to 10 carriers.
CLEC Competitive Local Exchange Carrier A telephone company that competes with an incumbent Local
Exchange Carrier (LEC).

integration with NMS regardless of programming language or
Operating System.
CPE Customer Premise Equipment Communications equipment that resides at the customer’s
location.
dB Decibel Unit of measurement for sound.
dBd Decibel/Dipole A ratio, measured in decibels, of the effective gain of an
antenna compared to a dipole antenna (2 horizontal rods in line
with each other). The greater the dBd value the higher the gain
and therefore the more acute the angle of coverage.
dBi Decibel/Isotropic A ratio, measured in decibels, of the effective gain of an
antenna compared to an isotropic antenna (measured along
axes in all directions). The greater the dBi value the higher the
gain and therefore the more acute the angle of coverage.
DHCP Dynamic Host Configuration
Protocol A protocol for dynamically assigning IP addresses to devices
on a network.
DiffServ Differentiated Service Different Quality of Service (QoS) descriptions for different
types of traffic, i.e., voice, video, email. The DiffServ table is
where each level of QoS is defined. Equivalent to Class of
Service (COS) in POTS.
DIR Directory A special kind of file used to organize other files into a
hierarchical structure.
DL DownLink In this case, data messages transmitted from the BTS to the
CPE.
DNS Domain Name Server TCP/IP networking term that is a protocol for matching objects
to network (IP) addresses.
DS-1
Digital Signal - 1 Also “T1” or “E1”. Digital transmission equipment that can
handle up to 1.544 Mbps.
DSL Digital Subscriber Line A type of service whereby users gain access to the Internet
through high-speed data networks.
