BreezeACCESS Series 1 Base Station Equipment Installation Manual
1. INTRODUCTION
This manual describes installation guidelines for BreezeACCESS base station
equipment, including the stand-alone AU-E/A-NI-Access Units and the modular
AU-E/A-BS-Units with the BS-SH rack mounted shelf.
The BreezeACCESS Broadband Wireless Access system allows access service
providers to provide high-speed IP connectivity services to their subscribers. To
support IP-based services effectively BreezeACCESS systems employ wireless
packet data switching technology.
The AU-A/E-NI and the AU-A/E-BS Access Units are comprised of an indoor
unit and an outdoor unit. In the AU-A-NI and AU-A-BS products, the outdoor unit
(AU-RA) contains the radio module and an integral flat antenna. In the AU-E-NI
and AU-E-BS products, the outdoor unit (AU-RE) contains the radio module and
an interface to an external antenna (not included).
The indoor unit of the AU-A/E-NI is a stand-alone unit (AU-NI) that is powered
from the mains via its AU-PS power supply unit. The indoor unit of the AU-A/E-
BS is a module (BS-AU) that is designed for insertion into the BS-SH shelf. The
BS-SH, which is a 3U shelf suitable for installation in 19" racks, can contain up to
six BS-AU active modules and one or two BS-PS power supply modules. The
shelf is powered from a –48VDC power source. Power supply redundancy is
supported through the optional use of a second BS-PS power supply module.
The indoor unit provides the interface to the network. It also contains an IF
(Intermediate Frequency) module and is connected to the outdoor unit via a
50-ohm coaxial IF cable. The IF cable serves for transmission of the 440MHz IF
signal between the indoor and the outdoor units. It also serves for transferring
power (12VDC), management and control signals from the indoor unit to the
outdoor unit.
