Au-A/E-Ni Standalone "Micro-Cell" Access Unit - Alvarion BreezeACCESS II System Manual

2-10
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-A/E-NI Standalone "Micro-Cell"
Access Unit
The AU-A/E-NI line includes standalone Access Units that are very
similar to the AU-A/E-BS units, 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-RA/RE outdoor units are identical to those of the AU-A/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.
