2.4 AAU RET SystemThe remote electrical tilt (RET) system of an AAU consists of the remote control unit (RCU),motor, gearing, and phase shifter. In the RET system, there are two logical RCUs which are usedto remotely adjust the downtilts of the two antenna arrays separately.

RET FunctionThe RCU receives the control commands from the base station and executes the commands todrive the step motor, which drives the phase shifter in the antenna through the gearing to adjustthe downtilt of the AU.

The following figure shows the working principles of the RET system.

Figure 2-17 Working principles of the RET system

RCU Serial Numbers

An AAU has two RCU serial numbers, which are printed on the AU label and uniquely identifythe RCU.

The RCU serial number has 19 characters and its encoding scheme is as follows: company code(two characters) + equipment type (seven characters) + reserved (two characters) + year (onecharacter) + month (one character) + sequence number (four characters) + DIN position (onecharacter) + array (one character). The following table describes the meaning of each field in anRCU serial number.

RET Configuration PrinciplesThe RET configuration principles are as follows:l The serial numbers of the logical RCUs, which do not have links, can be scanned by any

RET ports.l Links have no priority, and apply the first-come first-served principle. Only one AISG link

can be established for a logical RCU. If a link needs to be switched, you must delete theconfiguration on the link so that the link can be released for reuse.

l After the link is established for the logical RCU, the RCU serial numbers are not displayedin the scanning result of other RET ports.

l The RU in the upper slot is preferentially configured in the left array (L) and the RU in thelower slot is preferentially configured in the right array (R). The following table lists themapping between the AU arrays and the TX and RX channels of the RUs.

3.5 CPRI Fiber Optic CablesCPRI fiber optic cables are classified into single-mode fiber optic cables and multi-mode fiberoptic cables. CPRI fiber optic cables transmit signals between the BBU and RUs.

The maximum length of the multimode fiber optic cable between the BBU and RU is 150 m(492.12 ft).

A single-mode fiber optic cable consists of the single-mode pigtail and trunk single-mode fiberoptic cable, and the single-mode pigtail and trunk single-mode fiber optic cable areinterconnected using the ODF. The maximum length of the single-mode pigtail is 20 m (65.62ft) on BBU side and 70 m (229.66 ft) on RU side.
