unit (the same Universal IDU that is also used in the SU) rather than a 19”
module.
The AU-SA Access Unit can serve up to 512 Subscriber Units (124 when Data
Encryption is used).
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 5E 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.
NOTE
The AU-D/E-SA-ODU and the AU-D/E-BS-ODU are not interchangeable:
The AU-D/E-SA-ODU cannot be used with the BS-AU; the AU-D/E-BS-ODU cannot be used with
the standalone IDU.
