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-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 8 SUs except SU-54 (refer to section

1.3 for details on availability of SU types in different bands). Optionally, it
