Chapter 1 Welcome
Figure 1-1 Q-Lite™ Advanced Satellite Modem
The Q-Lite™ (Figure 1-1) satellite modem embodies a new concept in satellite modem
technology: a compact, state-of-the-art software-defined modem that can be easily
integrated into custom enclosures for comms-on-the-move and portable satellite
communication systems.
The Q-Lite™ L-band modem has a powerful processor that is ideal for handling IP traffic.
In common with other Q Series modems, it 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 150,000 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 Paradise’s Q Series modems, of which the Q-Lite™ is one, 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, state-of-the-art Forward Error Correction (FEC) saving up to 15%
bandwidth compared to Turbo Product Codes (TPC).
•5% spectral roll-off, saving 20% bandwidth compared with the standard 35% roll
off and saving over 10% bandwidth compared with 20% roll-off.
•IP compression, saving up to 50% bandwidth.
•Adaptive Coding and Modulation (ACM), saving up to 50% bandwidth.
•TCP Acceleration, enabling up to 93% bandwidth utilization for TCP traffic.
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 that monitors underneath the received
carrier for any interference, while on traffic.
The Q-Lite™ modem is backwards compatible with all Quantum and Evolution series
modems.
DVB-S2 is a highly efficient and robust coding and modulation standard for satellite
transmission that can significantly reduce satellite bandwidth requirements compared with
legacy standards.
Although DVB-S2 is primarily used for IP links, Paradise’s SmartLink™ technology
allows non-packetized continuous traffic, such as EIA-530 traffic, to also be used with
DVB-S2. The Q-Lite™ 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 in addition to, not instead of, 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-Lite™
satellite modem.
Redundancy Switch operation is documented separately – see ‘Installation and Operating
Handbook for Quantum, Evolution and Q Series Redundancy Switches’.

3.3 Electromagnetic Compatibility (EMC) Compliance
This satellite modem conforms to the provisions of EMC Directive 2004/108/EC and
complies with the following EC and FCC standards:
•Emissions: EN 55022:2006 Class B – ‘Information Technology Equipment –
Radio Disturbance Characteristics – Limits and Methods of Measurement’.
•Immunity: EN 50024:1998+A1:2001+A2:2003 – ‘Information Technology
Equipment – Immunity Characteristics – Limits and Methods of Measurement ’.
•Federal Communications Commission (FCC) Federal Code of Regulation Part
15, Subpart B.
All D-type connectors must have grounding fingers on the plug shell to guarantee
continuous shielding. The back-shells must comply with the requirements of VDE 0871
and FCC 20708, providing at least 40dB of attenuation from 30MHz to 1GHz. A good
quality cable with a continuous outer shield, correctly grounded, must be used.
Connections to transmit and receive IF interfaces must be made with double-screened
coaxial cable (for example, RG223/U).
The modem Ethernet ports should not be connected directly to outdoor Ethernet cables
that may be be subject to transient overvoltages due to atmospheric discharges and
faults in the power distribution network. Instead, the modem should be connected via an
Ethernet switch or router to provide isolation from overvoltages as recommended in
clause 6 of EN 60950-1.

Chapter 4 Installation
4.1 Unpacking
Prior to unpacking, inspect the exterior of the shipping container for any sign of damage
during transit. If damage is evident, contact the carrier immediately and submit a damage
report.
Carefully unpack all items, taking care not to discard any packing materials. Should the
unit need to be returned to Teledyne Paradise Datacom then you should use the original
packing carton as it is designed to provide the necessary level of protection during
shipment.
Once unpacked, visually inspect the contents to ensure all parts are present and that
there is no visible damage. Other than the unit itself, the shipping container should
contain a power cord and a Quick Start Guide.
4.2 Line Supply
This satellite modem is classified by the EN 60950-1 safety standard as a ‘Pluggable
Equipment Type A’. A regulated 24V DC power supply must be used. The power supply
connector on the Q-Lite™ allows for a second power supply to be connected in parallel in
order to provide protection against the failure of a single supply. Typical power
consumption is 30W; maximum power consumption is 100W.
No power supply or power cord is provided.
The installation of the satellite modem and the connection to the power supply must be
made in compliance with local and national wiring regulations for a Category II ‘impulse
over-voltage’ installation. The satellite modem should be positioned to allow a convenient
means of disconnection from the line supply.
4.3 Mounting in an Enclosure
The unit is shipped with an optional L-bracket that may be useful for any preliminary testing
of the unit prior to installation in its final enclosure, at which point the L-bracket would
normally be removed.
When designing an enclosure, it should be ensured that adequate ventilation and cooling
are provided. One fan connector is provided as standard and a second fan connector is
available on the optional Utilities Card.

4.4 Getting Started
Connect the appropriate cables to the transmit and receive L-band TNC connectors, along
with the cable for the traffic interface. If a front-panel keypad membrane and LCD display
have been provided then connect the cables for both of these to the appropriate Q-Lite™
connectors as shown in Figure.
Power the unit and wait for it to complete its initialization when it will display summary
status information.
From the front-panel menu, select Main->Edit->All in order to set the configuration prior to
operation.
It is also possible to set up the unit from a web browser as described in Section 7.4.
When setting up a number of units that have similar configurations, the configuration
settings of one unit can be saved, extracted and then transferred to each of the other
units in turn. This procedure is explained in Section 7.4.3.
Getting started is covered in more detail in the Q-Lite™ modem Quick Start Guide
(provided with the unit).
4.5 Enclosure Design Guidelines
The dimensions for the Q-Lite™ circuit board are shown in Figure 4-1. A higher
resolution drawing of the circuit board dimensions is available on request from Technical
Support.
The circuit board, as supplied, is suitable for incorporation into enclosures that mount the
board to a metal chassis and employ fans to move air out of the box. Power supply
regulation devices dissipate heat via the circuit-board mounting holes, which need to be
attached to a metal plate or chassis. Other devices dissipate heat into the enclosure and
and this typically will need to be expelled by a fan in the enclosure. The microprocessor
has its own fan to move heat away from the device locally.
The standard temperature range circuit board is suitable for mounting in enclosures that
have a 15 Celsius temperature rise in the enclosure and is capable of operating in an
ambient of 50 Celsius. The extended temperature range circuit board extends the
maximum temperature by 15 Celsius and the minimum from 0 Celsius to -20 Celsius.
It is possible to design an enclosure that does not have fans to remove heat. A heatsink
can be used to remove heat from any of the devices on the top of the board and the
mounting holes. Any such design could replace the microprocessor fan or it can be
retained if the design can make use of it. Any heatsink can itself be cooled by fans if
required. Thermal profile information for the board is available from Technical Support if
needed.
As measured from the top side of the circuit board, the highest component heights are as
follows:

•With no mezzanine, terrestrial or Utilities cards fitted: 13mm. This is due to the
10MHz external oscillator, which could potentially be removed after which the
heighest component is 8mm.
•With a mezzanine card (for DVB-S2, FastLink™ or Paired Carrier™) fitted:
13mm.
•With a terrestrial interface card fitted: 30mm.
•With a Utilities card fitted: 32.5mm.
When fitted with the L-bracket provided by Paradise, a 5mm stand-off is used underneath
the board and this height (or the equivalent measurement for any replacement bracket)
needs to be added to give the total height.

Chapter 5 Introduction
5.1 Overview
The Q-Lite™ satellite modem is designed primarily for closed network operation in mobile
environments, providing a data link between geographically distant sites via satellite.
Features include:
•DVB-S2 (EN 302 307) operation including Adaptive Coding and Modulation (ACM)
mode.
•L-band frequency range of 950MHz to 2050MHz.
•Closed network modes.
•G.703 E1 operation including Drop and Insert (D&I) via T1-D4, T1-ESF and G.732
bearer types.
•Variable data rate between 4.8kbps and 60Mbps. (Operation to 155Mbps is
possible in principle and will be supported in future.)
•BPSK, QPSK, Offset QPSK, 8PSK, 8QAM, 16QAM, 16APSK, 32APSK and
64QAM modulation schemes.
•Forward Error Correction (FEC) options of Turbo Product Code (TPC), FastLink
low-latency Low Density Parity Code (LDPC) and DVB-S2. (Other legacy FECs
such as Viterbi, Reed-Solomon, TCM and Sequential are available in principle and
can be supported on demand.)
•Spectral roll-off factors of 5%, 10%, 15%, 20%, 25% and 35%.
•A full range of terrestrial interfaces including Internet Protocol (IP), RS422, V.35,
RS232, LVDS, HSSI, STM-1, OC-3, Optical Ethernet and G.703 (T1/E1, T2/E2
and T3/E3). The Quad E1 interface card multiplexes four E1 interfaces together
onto a single carrier and also serial data, G.703 and IP traffic to be multiplexed
together onto a single carrier.
•Automatic Uplink Power Control (AUPC) automatically adjusts modem output
power to maintain a constant Eb/No at the distant end of the satellite link.
•Optional front-panel display and keypad for local control.
•Remote equipment can be controlled over the satellite via serial or IP traffic
interfaces. Remote modem control is supported via web browsing, the Simple
Network Management Protocol (SNMP), Telnet and the proprietary Paradise
Universal Protocol (PUP) command protocol. As well as supporting the
development of third-party user interfaces for modem control, the PUP protocol
includes many useful hooks for satellite listening applications (such as the output
of I and Q baseband samples).
•Compact 1U chassis, 405mm deep.
•XStream IP™, providing an advanced integrated suite of IP optimisation and
traffic management features. These include Transport Control Protocol (TCP)
acceleration, header and payload compression, encryption, static and dynamic
routing, Dynamic Host Control Protocol (DHCP), IEEE 802.1p Quality of Service
(QoS) support, IEEE 802.1q VLAN support, traffic shaping and Adaptive Coding
and Modulation (ACM). A dual IPv4/IPv6 TCP/IP stack is provided. IPv4 support is
provided for all IP functions as the default. With respect to IPv6, bridging and
routing are supported along with an IPv6 embedded web server. Modem IP
addresses and static routes can also be entered and displayed in IPv6 format.

TCP acceleration is supported at up to the maximum data rate for the modem.
Up to 10000 concurrent accelerated TCP connections are supported along with up
to 40,000 unaccelerated TCP connections. Bandwidth utilization when TCP
acceleration is enabled is typically over 90%. Bridging, static routing and
dynamic routing (RIP V1 and V2, OSPF V2 and V3 and BGP V4) are all
supported. Ethernet, IP, User Datagram Protocol (UDP) and Real Time Protocol
(RTP) header compression are supported. The 14-byte Ethernet frame is
typically compressed to one byte. IP/UDP/RTP headers are typically compressed
to between one and three bytes. The one-way packet processing limit for header
compression is 60,000 packets per second (pps); the two-way limit is 45,000 pps.
IP/UDP/RTP header compression is compliant with the RFC 3095 (Robust Header
Compression) standard. IP payload compression is provided (compliant with the
RFC 1951 ‘DEFLATE’ standard). This compresses TCP and UDP packet
payloads by typically 50%.
