Chapter 1 - System Description
The AU-D/E-BS-ODU outdoor unit contains the processing and
radio modules and connects to an external antenna using a short
RF cable.
E model units, such as the AU-E-BS-4900, are supplied without an
antenna and are primarily intended for Point-to-Point applications.
D model units, namely AU-D-BS-4900-360 and AU-D-BS-4900-120,
are supplied with a detached antenna, as listed in Table 1-1:

The BS-AU indoor module connects to the network through a standard IEEE
802.3 Ethernet 10/100BaseT (RJ 45) interface. The indoor module is connected
to the outdoor unit via a Category 5E Ethernet cable. This cable carries Ethernet
traffic between the indoor module and the outdoor unit, and also transfers power
(54 VDC) and control from the indoor module to the outdoor unit.
1.2.2 Standalone “Micro-cell” Access Unit
The standalone AU-D/E-SA Access Unit is very similar to the AU-D/E-BS unit.
The AU-D/E-SA-ODU outdoor unit is very similar to the
AU-D/E-BS-ODU outdoor unit (identical functionality, but the
units are not interchangeable). Units are differentiated based
on the availability of an antenna: E model units are supplied
without an antenna, while D model units are supplied with a
detached antenna.
Available units are:
AU-D-SA-4900-360 (Standalone AU with a 9 dBi omni antenna)
AU-D-SA-4900-120 (Standalone AU with a 15 dBi, 120° sector antenna)
AU-E-SA-4900 (Standalone AU)
The available antennas for D model units are the same as those of the AU-D-BS
Access Unit. The main difference is in the structure of the indoor part; in the AU-
D/E-SA Access Unit the indoor unit is a standalone desktop or wall-mountable
