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.

1.2.2Standalone “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

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