Chapter 7 Q-NET™ Implementation
This section shows some topologies used with Q-NET™ networks and includes some
information to help implement a Q-NET™ system.
The Q-NET™ satellite network solution is a highly flexible and scalable satellite network
solution designed for a broad range of markets, applications and business models. Its
unique selling points directly enable operators to dramatically cut costs and generate
additional revenue. Its defining characteristics are flexibility, low hardware costs and low
operational running costs.

Datacom introduced the
QMultiFlex-400™ modulator/multi-
demodulator unit for point-to-multipoint operation. A variant of our flagship QFlex-400™
satellite modem, it combines a highly efficient DVB-S2X shared outbound carrier with
support for multiple DVBS2X inbound carriers.
Q-NET™ supports both Layer 2 bridging (Star) and Layer 3 routing (Mesh). Q-NET™ can
therefore act as a transparent bridge for all protocols, or can be used to provide explicit
packet forwarding, as required. VLANs are fully supported (including VLAN access and
trunking modes and when applying traffic shaping rules).
All Paradise equipment and other network devices can be controlled from Q-NET™
Navigator, a client-side Windows application that supports a shared network database for
all operators. It provides full control over all modem and multi-demodulator functions using
an easy-to-navigate site map, which also displays the real-time alarm status of each
modem. It can take care of automatically synchronizing all changes in the network when
shared outbounds or inbounds need to be reconfigured.
