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
