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-E-SA Access Unit is very similar to the AU-E-BS unit. The
difference is in the structure of the indoor part; in the AU E-SA Access Unit the
indoor unit is a standalone desktop or wall mountable unit (the same Universal
IDU that is also used in the SU) rather than a 19" module.
There are two types of Standalone Access Units, differing in the maximum
number of Subscriber Units that they can serve:
The AU-SA Access Unit can serve up to 512 Subscriber Units (124 when Data
Encryption is used).
The AUS-SA Access Unit can serve up to 25 SUs except SU-54 (refer to section
1.3 for details on availability of SU types in different bands). Optionally, it may
be licensed to support also SU-54 units (in bands where SU-54 unit type is
available.).
The IDU connects to the network through a standard IEEE 802.3 Ethernet
10/100BaseT (RJ 45) interfaces and is powered from the 110/240 VAC mains.
The indoor unit is connected to the outdoor unit via a Category 5 Ethernet cable.
This cable carries Ethernet traffic between the indoor and the outdoor units, and
also transfers power (54 VDC) and control from the indoor unit to the outdoor
unit.
