BreezeACCESS Version 4.3 System Description
Manual Revision: 4.0
Subscriber Units (Customer
Premises Equipment)
The BreezeACCESS Subscriber Unit (SU) installed at the customer
premises provides data only or data and telephone connections. The
data connection is a standard IEEE 802.3 Ethernet 10BaseT (RJ 45)
interface while the voice connection (in units that support voice) is a
standard RJ 11 Plain Old Telephone (POTS) interface.
The Subscriber Unit provides an efficient platform for high rate Internet
and Intranet services, providing subscribers with fast access to IP based
services at a burst data rate of up to 3 Mbps. The use of packet
switching technology provides the user with a connection to the network
that is practically always on, allowing for immediate access to services.
SU-A/E Units with an Outdoor Radio
Unit and Antenna
SU-A and SU-E series Subscriber Units are comprised of an indoor unit
(SU-NI) and an outdoor unit.
 In the SU-A series, the outdoor unit (SU-RA) contains the radio
module and an integral flat antenna.
 In the SU-E series, the outdoor unit (SU-RE) contains the radio
module and an RF connector for an external antenna.
The indoor SU-NI unit connects to the user’s equipment and is powered
from the mains via its SU-PS power supply unit. The SU-NI is connected
to the outdoor unit via a 50-ohm coaxial Intermediate Frequency (IF)
cable. This cable carries 440 MHz IF signals between the indoor and the
outdoor units and also serves for transferring power (12 VDC),
management and control signals from the indoor unit to the outdoor
unit.
