It applies to scenarios such as GO, UO, LO, GU and GL. Panel MRFUs fall into three types: MRFU V1, MRFU V2, and MRFU V2a. The three types of MRFUs can be identified by their labels. As shown in Figure 3-11, there is "V0" or "V1" on the label of a MRFU V1, there is "V2" on the label of a MRFU V2, and there is "V2a" on the label of a MRFU V2a. Figure 3-11 MRFU Panel Function The functions of MRFU are as follows: l Modulates and converts the signals to the TX band by up-converting the intermediate frequency (IF) signals, filters and amplifies the signals and then transmits the signals to the antenna through the duplexer. l Receives radio frequency (RF) signals from the antenna system, down-converts the signals to IF signals, and then transmits them to the baseband unit (BBU) after an amplification, Issue 13 (2014-06-26) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 41 matched filtering.BTS3900 (Ver.

If any board or component is faulty, an alarm is reported automatically. The alarm signals are collected both inside and outside the cabinet by the UPEU, UEIU, or EMU to ensure that the entire base station can be monitored. 5.1 Monitoring Principles of the Cabinet The BTS3900 cabinet is managed by monitoring boards, such as the FMU and PMU. Each monitoring board is connected to the MON port on the BBU. They collect alarms of all components and report the alarms to the BBU by using the RS485 serial bus. 5.2 Customized Alarm Inputs When an alarm is generated by the customized equipment, the alarm must be reported to the BBU. 5.3 Monitoring Boards of the BTS3900 The monitoring boards of the BTS3900 collect monitoring signals and then report the monitoring signals to BBU3900.
