Figure 1-1 QMultiFlex-400™ Advanced Satellite Modem

The QMultiFlex-400™ (Figure 1-1), a variant of our versatile QFlex-400™ satellite

modem, is a modulator/multi-demodulator system that supports efficient, cost-effective

point-to-multipoint IP operation.

This handbook will guide you throughthe process of setting up and using your QMultiFlex-

400™ satellite modem and point-to-multipoint network.

We refer to the QMultiFlex-400™ as a ‘hub-in-a-box’because it incorporates all the

following functions in a single rack unit, which replaces a whole rack of traditional hub

equipment:

•Modulator

•Multiple demodulators

•Ethernet managed switch

•Router

•IP bandwidth optimizer

•ACM controller

•Packet encapsulator/decapsulator

•Spectrum analyser

•Oscilloscope (constellation monitor)

•Traffic generator/analyser

•Redundancy system controller

•Embedded hub canceller

The QMultiFlex-400™ supports a highly efficient shared DVB-S2/S2X outbound carrier

with multiple DVB-S2/S2X inbounds and can be used for star, full mesh and hybrid

networks.

The QMultiFlex-400™ supports a layer 2 bridge (Star Topology) and a layer 3 router (Mesh

Topology). QMultiFlex-400™ can therefore act as either a transparent bridge for all

protocols (including tunneling protocols, VPNs & VLAN trunks etc) or it can perform explicit

packet forwarding, as required.

The QMultiFlex-400™ and associated QFlex-400™remote modems can be controlled

from a web browser using the built-in web user interface that is supported on each device.

Alternatively, a QMultiFlex-400™ network can be controlled via our Q-NET™Navigator,

to visualize the status of a complete network at-a-glance. The QMultiFlex-400™

interoperates with Q-Lite™ and Q-Flex™/QFlex-400™P2MP remote network modems.

The satellite bandwidth-saving features include:

•DVB-S2 and DVB-S2X state-of-the-art Forward Error Correction (FEC)

representing the most bandwidth-efficient FEC technology available. Now

available for both inbounds and outbounds.

•Spectral roll-off factors down to 5%, saving up to 15% bandwidth compared with

20% roll-off.

•Embedded Hub Canceller allowing satellite BW savings of up to 50%.

•Adaptive Coding and Modulation (ACM), saving up to 50% bandwidth.

•Variable Coding and Modulation (VCM), up to 6 IP streams with individual

MODCODS for optimal per-site throughput.

•9-tap Rx adaptive 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.

DVB-S2X, the successor to DVB-S2, is themost efficient and robust codingand modulation

standard available for satellite transmission and supports transmission of modulations up

to 64APSK.

Redundancy Switch operation is documented in ‘Q-NET™ PDQS Redundancy Switch

Installation and Operating Handbook’.
