Logic Structure of BBU3900

The BBU3900 consists of four logical subsystems: control,

transport, baseband, and power and environment

monitoring


LMPT (The LTE Main Processing & Transmission Unit )

Mandatory, Maximum 2 board, hold in slot 7(default)

or 6

Function:

Performs configuration management, equipment

management, performance monitoring, signaling

processing, and radio resource management

Controls all boards in the system

Provides the system clock and transmission ports


LBBP (The LTE Baseband Processing Unit)

Mandatory, Maximum 3 boards, hold in slot 1(default),2 or

3

Function: Processes uplink and downlink baseband signals

Provides CPRI ports for communication between BBU3900

and RRUs

The LBBPc can be used in both FDD LTE and LTE TDD modes

UTRP (The Universal Transmission Processing unit )

Optional, maximum 2 modules

The UTRP performs the following functions:

Provides ports for eight E1s/T1s based on the IP

protocol.

Deframes and frames of the HDLC, and allocates and

controls 256 HDLC timeslots.


USCU (The Universal Satellite card and Clock Unit )

The USCU performs the following functions:

The USCU provides interface for an external RGPS device

(such as a reused device of the operator), BITS device, and

TOD input

The USCUb0 does not provide the satellite card

The USCUb2 supports GPS and GLONASS with two built-in

satellite cards

OCB

An Outdoor Cable Conversion

Box (OCB) interconnects

cables of different core

diameters. Power cables

shipped with RRUs cannot

support long-distance power

supply. Therefore, when

power supply is far from the

equipment, cables with large

core diameters are used, and

an OCB connects these

cables and RRU power cablesPage48
