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.

The standalone AU-E-SA Access Unit is very similar to the AU-E-BS unit. The
only 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 8 SUs except SU-54 (refer to section
1.3 for details on availability of SU types in different bands). Optionally, it
may b
e licensed to support also SU-54 units (in bands where SU-54 unit type
is available).
NOTE
For convenience, all references to AU-SA are applicable also for AUS-SA, unless explicitly stated
otherwise.
The IDU connects to the network through a standard IEEE 802.3 Ethernet
10/100BaseT (RJ 45) interfaces and is powered from the 110/220 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.
