Chapter 1 Welcome
Figure 1-1 Q-Flex™ Advanced Satellite Modem
The Q-Flex™ (Figure 1-1) satellite modem embodies a new concept in satellite modem
technology: a flexible software-defined modem that does what you want, now and in the
future. The Q-Flex™ modem provides a flexible hardware platform with support for IF
(70/140MHz) and L-band operation in one unit. Its powerful processor is ideal for handling
IP traffic. However, the Q-Flex™ modem can be fitted with virtually any type of terrestrial
interface and will operate at data rates up to 160Mbps.
Low cost of ownership is supported by a pay-as-you-go feature set, where individual
features can be enabled when required.
The Q-Flex™ modem incorporates a new software suite called XStream IP™. This has
been created in response to a perceived widespread dissatisfaction in the industry with
the usability and quality of service provided by IP-over-satellite in general. Paradise has
re-engineered every aspect of IP support from the ground up to ensure ease of use, a
high degree of integration between features and outstanding performance and efficiency.
Specifically:
•XStream IP™ is the most advanced integrated suite of IP optimisation and traffic
management features available in any satellite modem.
•XStream IP™ is specifically optimised to be highly efficient and reliable over satellite.
•XStream IP™ provides up to 500,000 packets-per-second processing capability for
lightning-fast IP throughput.
•XStream IP™ is simple to set up and use.
•XStream IP™ includes all IP features as standard making it very good value.
The design aim for the Q-Flex™ was to create the industrys most versatile and
bandwidth-efficient satellite modem. Among the satellite band-width saving features
available are:
•Paired Carrier™, allowing two carriers to be overlapped in the space segment,
saving up to 50% bandwidth.
•DVB-S2 and DVBS2X, state-of-the-art Forward Error Correction (FEC)
representing the most bandwidth-efficient FEC technology available.
•Spectral roll-off factors down to 5%, saving up to 15% bandwidth compared
with 20% roll-off.
•IP compression, saving up to 50% bandwidth.
•Adaptive Coding and Modulation (ACM), saving up to 50% bandwidth.

Q-Flex Satellite Modem Installation and Operating Handbook

•TCP Acceleration, enabling up to 93% bandwidth utilization for TCP traffic.
•ClearLinq™ adaptive Tx pre-distorter, providing up to 2dB compensation for
linear and non-linear distortion in the channel.
•9-tap Rx equaliser, providing compensation for linear distortion in the channel,
such as from group delay. The equaliser is automatically switched on in all
modes of operation above 10Msps.
New levels of usability are provided by a leading set of built-in diagnostic tools including
spectrum and constellation monitors that facilitate the detection of any link degradation. In
addition, LinkGuard™ is patented technology (US patent 8351495) that monitors
underneath the received carrier for any interference, while on traffic.
The Q-Flex™ modem is backwards compatible with all Quantum and Evolution series
modems.
DVB-S2X, the successor to DVB-S2, is the most efficient and robust coding and
modulation standard available for satellite transmission.
Paradise’s SmartLink™ technology allows non-packetized continuous traffic, such as
G.703 E1 traffic, to be used with DVB-S2. The Q-Flex™ therefore provides a painless
migration path to newer, more efficient communications technology while fully supporting
legacy services.
FastLink™ Low-Density Parity-Check (LDPC) Forward Error Correction (FEC) combines
high coding gain with low latency. FastLink™ can therefore be used to replace both
conventional LDPC (which has high latency) and Turbo Product Code FEC (which has a
lower coding gain).
Paired Carrier™ allows space segment reuse. It overlays transmit and receive carriers in
the same space segment reducing satellite bandwidth requirements by up to 50%. It can
be used at the same time as all our other bandwidth saving techniques. It incorporates
ViaSat’s patented PCMA technology, which is protected under U.S. patent numbers
5,596,439, 6,011,952 and 6,725,017.
This handbook will guide you through the process of installing and using your Q-Flex™
satellite modem (including the Q-FlexE™ and Q-FlexV™ versions).
