SCPC
Single Channel Per Carrier
Short frames
DVB-S2 frames 16200 bits long (including FEC). Advisable to use at lower symbol rates. Produce less delay than Long
frames.
SNMP
Simple Network Management Protocol
SNTP
Simple Network Time Protocol (SNTP) is a protocol and software implementation for synchronizing the clocks of
computer systems over packet-switched, variable-latency data networks.
SNR
Signal-to-noise ratio is an electrical engineering measurement defined as the ratio of a signal power to the noise power
corrupting the signal.
SR
Symbol Rate
Star
Type of network with one central station (hub) and several peripheral stations.
SW
Software
TDM
Time Division Multiplexing
TDMA
Time Division Multiple Access
Telnet
Telecommunication Network (Telnet) is a network protocol used on the Internet or local area networks to provide a
bidirectional interactive communications facility. Typically, telnet provides access to a command-line interface on a
remote host via a virtual terminal connection.
Terminal
Earth Stations (usually VSAT) operated under management of network HUB
TFTP
Trivial File Transfer Protocol (TFTP) is a file transfer protocol, with the functionality of a very basic form of File Transfer
Protocol (FTP).
Timestamp
Time format used by UHP. Plus sign at the beginning (+HH:MM:SS or +NN d HH:MM:SS)denotes relative time from some
event or UHP start-up. If UHP has time synchronized to hub or SNTP absolute time can be displayed. Time zone affects
absolute time.
Time-slot
Time interval for station transmission.
UDP
The User Datagram Protocol (UDP) is the set of network protocols used for the Internet. With UDP, computer
applications can send messages, in this case referred to as datagram, to other hosts on an Internet Protocol (IP) network
without requiring prior communications to set up special transmission channels or data paths.
USB
USB (Universal Serial Bus) is a specification to establish communication between devices and a host controller (usually
personal computers).
VLAN
A virtual LAN, commonly known as a VLAN, is a group of hosts with a common set of requirements that communicate as
if they were attached to the same broadcast domain, regardless of their physical location.
VoIP
Voice over Internet Protocol (VoIP) is a general term for a family of transmission technologies for delivery of voice
communications over IP networks such as the Internet or other packet-switched networks.
VSAT
Very Small Aperture Terminal – satellite earth station with small-size antenna
WFQ
Weighted fair queuing. Method of proportional division of bandwidth between transmission queues.
X-modem
Simple file-transfer protocol
