BPS Bits Per Second – A measure of transmission speed. See also kb/s &
Mb/s.
BPSK Binary Phase Shift Keying – A modulation technique in which the carrier is
phase shifted +/-180 degrees. See also QPSK.
C
C-Band A frequency band commonly used for satellite communications (and sometimes
terrestrial microwave). For terrestrial earth stations the receive frequency band
is 3.7-4.2 GHz and transmit 5.925-6.425 GHz. See also Ku-band.
CRC Cyclic Redundancy Check – A method of applying a checksum to a block of
data to determine if any errors occurred during transmission over communica-
tions links.
CXR Carrier – A radio frequency transmission bearer linking points and over which
information may be carried.
D
DAMA Demand Assigned Multiple Access – A process whereby communications links
are only activated when there is an actual demand.
dBm Decibel referenced to 1 milliwatt.
DHCP Dynamic Host Configuration Protocol – An Internet protocol for automating
the configuration of computers that use TCP/IP.
DNA Dynamic Node Announcement – In VIPERSAT satellite networks a process
whereby remote sites periodically announce their presence to facilitate network
setup and monitoring.
DPC Dynamic Power Control
DRAM Dynamic Random Access Memory
DSP Digital Signal Processor – A microprocessor chip optimized for signal process-
ing applications.
DVB Digital Video Broadcast
DVP Digital Voice Processor – The VIPERSAT voice card used in packet voice
applications.
