Chapter 1 Welcome
Figure 1-1 QubeFlex Satellite Modem
The QubeFlex satellite modem (Figure 1-1) embodies a new concept in satellite modem
technology: a short chassis, flexible software-defined modem, which allows an easy future
upgrade path. The Modem provides a flexible hardware platform with support for IF (50 -
180MHz) and L-band (950 –2450MHz) operation in one unit. Its powerful processor is ideal
for handling IP traffic. However, the QubeFlex modem can be fitted with EIA-530 (for X.21,
RS422, V.35 and RS232 operation) or high speed LVDS terrestrial interfaces and will
operate at data rates up to 50Mbps (for IP operation).
The design aim for Paradise’s Q Series modems, of which the QubeFlex is one, was to
create the industry’s most versatile and bandwidth-efficient satellite modem. Core features
available are:
•CCSDS & Intelsat Forward Error Correction, Forward error correction ensures data
is protected against transmission loss
•Spectral roll-off factors down to 5%, saving up to 15% bandwidth compared with
20% roll-off.
•Extended Roll-offs, Extends base modem carrier roll-offs to include up to 60% roll-off
(selectable in 1% increments)
•Extended Doppler, Extends base modem Doppler limits from ±255kHz, ±2.1kHz/s to
±700kHz, ±9kHz/s
•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™(U.S. patent 8351495) monitors underneath the received carrier for
any interference, while on traffic.
This handbook will guide you through the process of installing and using your QubeFlex
satellite modem.

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 with a view to submitting a damage
report.
Carefully unpack all items, taking care not to discard any packing materials. If the unit needs
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 62368-1 safety standard as a ‘Pluggable
Equipment Class A’. The mains operating range is 90V to 264V. A 48V DC input option is
available. Power consumption ranges from 40W to amaximum of 300W (when a BUC PSU
is fitted).
A power cord suitable for use in the country of operation 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 Rack Mounting
If the unit is being installed in a rack, then adequate ventilation and cooling should be
provided. There must beadequate clearance around the side and rear mounted fans and the
ventilation holes on both sides of the unit.
For rack mounting, there are screw positions on the unit’s front panel for attaching it to the
rack, which prevent the unit from moving. These must always be used in conjunction with
full-length L-brackets fitted on both sides of the unit (or a tray underneath the unit) to support
its weight.
A 1U gap between units in the rack is not necessary but if extra space is available then any
gap will help to minimise the temperature inside each unit, which may contribute to improving
long-term reliability (due to the relationship between temperature and reliability of electronic
components).

QubeFlex Satellite Modem Installation and Operating Handbook

5.6 QubeFlex Rear Panel
The rear panel, shown in Figure 5-3, provides a full set of terrestrial and satellite data
interfaces. Connector pinouts are defined in Chapter 10 .
Figure 5-3 The Modem Rear Panel
From left to right, the rear panel consists of:
•IEC Mains Power Connector/Voltage Selector/Fuse
The modem is designed to operate from a mains AC supply of 90V to 264V (1A @100V,
0.5A @ 240V, 47 to 63Hz). The IEC connector incorporates two fuses, independently
fusing both live and neutral lines. Access to the fuses is provided by a slide-out tray. Both
fuses are standard 20mm type, rated T3.15A, of the slow-blow (time-delay) type.
•Chassis Ground Stud
There is an M4 stud for connecting a safety earth conductor directly to the chassis of the
unit.
•USB port
This is a USB host, so slave devices can be connected. Available for software upgrades
and transferring configuration memories. USB versions 1 and 2 are supported.
•Alarms and AGC Connector
This is a 15-pin D-type male connector that provides access to four ‘form-C’ relay
contacts that indicate alarm conditions. An AGC output is provided that is suitable for
peaking antenna position.
The alarm relays have the following definitions:
Unit Fault: A fault exists on the unit indicating an equipment failure.
Tx Traffic Prompt: A Tx traffic fault exists.
Rx Traffic Prompt: An Rx traffic fault exists.
Deferred Alarm: One of the following conditions exists:
• The receive Eb/No is lower than the user-defined threshold.
• Buffer slips are more frequent than the user-defined threshold.
• A backward alarm is being received from either the satellite or terrestrial ports.

•1:N Redundancy Connector
The modem has a built-in 1:N redundancy controller, facilitated via a 9-pin D-type male
connector. The redundancy controller allows working directly with another Modem in a
1:1 pair or with a 1: N PDQS Redundancy Switch. A 1:1 redundancy system requires two
modems, a 1:1 control cable between the two redundancy connectors, a ‘Y’ cable for
splitting the traffic path and passive splitters and combiners for the IF ports. An overview
of 1:1 operation is provided in Section 7.2
Note: By default, the 1:N connector functions as serial M&C and must be enabled on the
factory menus for 1:N operation.
•Station Clock
The Station Clock connector is not used on QubeFlex.
•Fans
Thereisone rear andone sidemountedhigh performancefan fitted tothe chassis, these
draw air in through the ventilation holes. These holes and the side vents must not be
blocked.
•Tx N Type Connector
This provides both an IF and L-Band output towards the satellite and is provided using
a 50Ω N type connector.
The IF covers 50 to 90Mhz and 100 to 180MHz bands with a resolution of 100Hz.
Transmit output power is variable between 0 to –25dBm in 0.1dB steps.
L-Band covers 950 to 2450MHz with a resolution of 1Hz. Transmit output power levels
conform to the following table, variable in 0.1dB steps.
+5 to –40dBm between 950 to 1950MHz
0 to –40dBm between 1950 to 2150MHz
0 to –30dBm between 2150 to 2450MHz
•Optional Terrestrial Interface Positions
Two terrestrial interface positions support EIA-530 and/or LVDS interface cards.

QubeFlex Satellite Modem Installation and Operating Handbook
5-10
•Ethernet Connectors
Four Gigabit Ethernet RJ45 connectors are provided for modem Monitor and Control
(M&C) and satellite traffic. Ethernet speed, duplex and cable termination (crossover
versus straight-through) are auto-negotiated. Line speed and duplex can also be set to
fixed values. The Ethernet ports can be bridged together under software control. If the
software option to remove the M&C port from the bridge is invoked, then port 1 of the
four-port switch is reserved for M&C only (and the other ports for IP satellite traffic).
When the M&C port is bridged to the other ports, M&C and traffic can be passed using
any port.
M&C control can be via the Simple Network Management Protocol (SNMP), an
embedded web server that sends web pages to a web browser, a Telnet-style terminal
emulation application or via TCP packets that encapsulate Paradise Universal Protocol
(PUP) commands.
SNMP is disabled by default and must be enabled before it can be
used. When enabled, the modem will always respond to SNMP
commands regardless of whether it has been placed in a mode that
restricts user control to the front panel only.
When using the M&C interface, an M&C IP address (including subnet mask and default
gateway) must be set. An IP traffic address is not required when operating in Ethernet
bridging modes. IP addresses are described in Section 7.6.2.
When the M&C Ethernet port is out of the bridge then satellite IP traffic
and M&C traffic are processed separately and therefore the M&C and
traffic Ethernet connectors are no longer interchangeable. Care
should be taken in selecting this mode for a remote modem since if
the cables have been incorrectly fitted then it could result in M&C
communications with the remote modem being lost.
