BreezeACCESS Version 4.3 System Manual
Daisy-chained BS-GU modules use the synchronization signals
generated by the first module in the chain (the Master module.
The BS-GU module also supports the management of alarm inputs and
outputs. The module receives Alarms In indications from other
BreezeACCESS modules in the base station shelf (internal alarms) and
external alarms from other devices via the AL IN connector. Alarms Out
management allows activation of external devices upon occurrence of
user-defined events, using relays via the AL OUT connector.
AU-E-NI Standalone “Micro-Cell”
Access Unit
The AU-E-NI is a standalone Access Unit that is very similar to the
AU-E-BS unit, the only difference being that the indoor unit, the AU-NI,
is a standalone desktop or wall-mountable unit rather than a 19”
module.

The AU-RE outdoor unit is identical to that of the AU-E-BS line. The
AU-NI indoor unit is powered from the mains (100-250 VAC) through an
external power transformer and connects to the network through a
standard IEEE 802.3 Ethernet 10BaseT (RJ 45) interface. A coaxial
Intermediate Frequency (IF) cable connects between the AU-NI indoor
unit and the outdoor unit. This cable carries 440 MHz IF signals, power
(12 VDC) and management and control signals from the indoor unit to
the outdoor unit.
