AISG IN
RET antenna port connected to the RET port on a passive module
AISG OUT
RET antenna cascading port connected to the RET antenna port on an external RET antenna so that the passive module can adjust downtilts of cascaded antennas
Functions The following figure shows the function process of an AU. Figure 2-13 Function process of an AU
The AU performs the following functions: l
Remotely adjusts the downtilts: The Remote Control Unit (RCU) receives RS485 signals, converts the received RS485 signals, and sends the converted signals to the motor; the motor converts received signals into phase shift and drives the phase shifter using a gear, enabling the downtilt adjustment of the antenna arrays.
l
Combines signals: The combiner combines RF signals of different frequency bands and then sends these signals to the antenna array through the feeder power network.
l
Receives and transmits signals: The antenna array receives and transmits RF signals.
l
Reports information: The RCU reports the AU basic information and RU slot information.
l
Provides ports for RU mounting kits and AAU mounting kits.

2.3 AAU Combinations An AAU is an active antenna unit that can be connected to RRUs and RFUs in the live network. NOTE l
When an RF module is installed in the rear plastic housing of an AU, it is called an active module, shortened to A.
l
When an RF module is not installed in the rear plastic housing of an AU, it is called a passive module, shortened to P.
l
In this section, A is an RU, P can be an RRU or RFU from Huawei or other manufactures.
There are three types of AAU combinations based on the number of configured A and P: one A+one P, two As, two As+one P, as shown in the following figure. Figure 2-16 AAU Combinations
(1) Active module (A)
(2) Passive module (P)
NOTE
When 2-port RRUs or RFUs are configured, connect cables in the way indicated by the solid lines shown in the preceding figure.
The following table describes the AAU combinations classified by the frequency bands of the configured A and P. Issue 07 (2015-12-30)
