Working Principles and Functions of the BBU A BBU is a baseband unit. It processes baseband signals of a base station.
Working Principle A BBU consists of the following subsystems: baseband subsystem, power and mechanical subsystem, transmission subsystem, interconnection subsystem, main control subsystem, monitoring subsystem, and clock subsystem. Each subsystem consists of different modules. l
Baseband subsystem: baseband processing unit
l
Power and mechanical subsystem: backplane, fan module, and power module
l
Transmission subsystem: main control and transmission unit
l
Interconnection subsystem: main control and transmission unit
l
Main control subsystem: main control and transmission unit
l
Monitoring subsystem: power module and monitoring unit
l
Clock subsystem: main control and transmission unit as well as satellite card and clock unit
The following figure shows the working principle of a BBU.

l
Provides ports for connecting to the transmission equipment, RF modules, USB devicesa, external reference clock, and LMT or U2000 to transmit signals, perform automatic base station software upgrade, receive reference clock signals, and support maintenance on the LMT or U2000.
l
Manages the entire base station system. The management involves uplink and downlink data processing, signaling processing, resource management, and operation and maintenance. NOTE
a: The security of the USB loading port is ensured by encryption, and the USB loading port can be shut down using commands. The USB commissioning port is used for commissioning the base station rather than configuring and exporting information of the base station.

a and b: FE/GE electrical ports and FE/GE optical ports on a UMPT can be used at the same time. c: The security of the USB port is ensured by encryption, and the USB port can be shut down using commands. d: When the USB port functions as a commissioning Ethernet port, ensure that an OM port has been enabled and the user has obtained required authorities for accessing the base station through the OM port before accessing the base station through the USB port. e: When the status of the CI port on the UMPTe board is switched to DOWN, the transmission bearing configuration is deleted. In this case, the base station does not report transmission-related alarms because no transmission bearing configuration is available. l
The possible reason for the DOWN status of CI port is that the fiber optic cable connected to the CI port is removed or that the peer device is powered off.
l
Transmission-related alarms include SCTP Link Fault, IP Address Conflict, and IP Transmission-related Excessive Frame Error Rate.

For a UBBPd2/UBBPd4/UBBPd5/UBBPe2, the sum of x of x and and y y is is less than or equal to 6. For a UBBPd1/UBBPd3/UBBPd6/UBBPe1/UBBPe3/UBBPe4/UBBPe5/UBBPe6/UBBPei, the sum of of x x and and 2 y is y is less than or equal to the number of 2R cells supported by the board, and y y is is less than the number of 4R cells supported by the board.

Specifications of UBBP boards working in co-BBP scenarios
Co-BBP enables one baseband processing board to process baseband signals for multiple modes. Co-BBP is supported only in co-MPT base stations. For co-BBP specifications of UBBP boards working in multiple modes, see "Technical Specifications of the BBU" in "Technical Description".
Function A UBBP performs the following functions: l
Provides CPRI ports for communication with RF modules.
l
Processes uplink and downlink baseband signals.
l
Supports the multiplex of baseband resources among different modes, thereby implementing multimode concurrency concurrency..
Working Principle The following figure shows the working principle of a UBBP. UBBP. Figure 6-12 Working principle of a UBBP

Function An FANf performs the following functions: l
Dissipates heat from other boards in the BBU.
l
Controls the speed of fans, monitors the temperature of fans, and reports the status, temperature, and in-position signals of fans.
l
Provides a read/write electronic label.
6.8 Optical Modules An optical module transmits optical signals between an optical port and a fiber optic cable. NOTE l
The exteriors of an optical module and the label on an optical module in this section are for reference only. The actual exteriors may be different.
l
Boards or RF modules supporting only the 1.25 Gbit/s CPRI port rate, for example, a GTMU or RRU3908 V1, cannot use 10 Gbit/s optical modules.
l
A fiber optic cable must use the same type of optical modules on its two ends. If different types of optical modules are used by a fiber optic cable, performance risks may arise, for example, alarms, bit errors, and interrupted links.
l
Only Huawei-certified optical modules meeting the following requirements can be used for Huawei wireless devices:
l
l
Requirements of devices on which optical modules are to be installed
l
Laser safety in the IEC 60825-1 standard
l
General safety in the IEC 60950-1 standard
For SFP or QSFP optical modules certified and provided by Huawei, see Spare Parts Catalog .
