The DW4000 series of DIRECWAY systems
delivers the speed, security, ubiquity and scalability of broadband
by satellite at a surprisingly affordable price. Now there is a faster,
better, easier way to work and to play at your PC. The DW4000 series
DIRECWAY system communicates with geostationary satellites in a "two-way"
manner; i.e. the receive (or down-stream) data and the transmit (or
upstream) data signals both operate through the system's antenna, over
the satellite, and via the DIRECWAY Network Operations Center. No phone
line, no dial-up connection. And with the DW4000 your DIRECWAY link
is always on.
The DIRECWAY DW4000 series systems consist of an oval satellite antenna,
matching integrated outdoor electronics, and the indoor units which
connect to a USB-enabled PC (see below for further descriptions). Outdoor
equipment for international units varies based on which satellite is
The indoor equipment consists of two USB satellite adapters: the ITU
and the IRU. The IRU is a DVB compliant satellite adapter used together
with the ITU for two-way operation. The DIRECWAY ITU is designed to
be an add-on capability to a standard receive-only DIRECWAY IRU. When
the ITU is installed and configured, the user will have the ability
to select the satellite instead of the modem as the outbound route.
When this option is selected the system is essentially "always
on". This means you never have to wait for your PC to connect,
or worry about ISP busy signals. And because the ITU is connected to
the IRU through the ITU-IRU interconnection cable, only one USB port
on your PC is required to operate the DIRECWAY indoor equipment.
The DIRECWAY antenna is equipped with the following: a single LNB to
receive DIRECWAY data from the satellite; a radio unit to transmit DIRECWAY
data to the satellite (DW4000 series only). In addition, each DIRECWAY
system can be optionally equipped with an additional dual-LNB to receive
Direct Broadcast Satellite TV using the same antenna. This configuration
is called DirecDuo and in the U.S. is compatible with the DIRECTV satellite
television service. The outdoor equipment is connected by two RG-6 coaxial
cables to the indoor equipment.
