BBU Hardware Structure

The typical power consumption of the BBU is 35 W.

The weight of the BBU isnt more than 10KG.

The BBU is a small box with all the external ports on the front panel.

The BBU3900 boards consist of the BSBC, UEIU, GTMU, and

UELP; the BBU3900 modules consist of the UBFA and the UPEU.

BBU Cable connection

The BBU3900 cables are classified into the PGND cable, -48VDC

power cable, E1/T1 cable, E1 transfer cable, environment monitoring

signal cable, CPRI signal cable between the BBU and the RRU, and

BBU monitoring signal cable.

The cable connection relations of the BBU are as follows:


6/23


BBU Board--GTMU The GSM transmission, timing, and management unit for BBU (GTMU)

controls and manages the entire BTS. It provides interfaces related to

the reference clock, power supply, OM, and external alarm collection.

The GTMU performs the following functions: Controls, maintains, and operates the BTS.

Supports fault management, configuration management, performance

management, and security management.

Supports the monitoring of the fan module and power supply module. Distributes and manages BTS3900 clock signals.

Provides clock input for testing.

Provides port for terminal maintenance.

Supports four E1 inputs.

Provides CPRI ports for communication with the RF modules .

APM30 Battery Cabinet Hardware

Component The battery cabinet consists of :

Batteries in the APM30 Battery Cabinet

Door Status Sensor

Heating film


13/23


PDU Module The PDU (short for Power Distribution Unit) performs AC or DC power

distribution. The AC distribution functions of the PDU are as follows:

Supplies two AC power outputs with the maximum current of 10 A to the heaters

of the power cabinet and the heating film of the battery cabinet.

Reports the surge protection alarms of the AC input power .

The DC distribution functions of the PDU are as follows:

Provides 10 DC power outputs to meet the DC power requirements of t

he distributed base station or the separated base station

Reports the surge protection alarms of the DC output power

Batteries in the APM30 Battery

Cabinet The battery cabinet supports two types of batteries, the -48 V 50 AH

and the -48 V 100 AH. The batteries can be grouped into the followingcombinations:

When the -48 V 50 AH batteries are configured, they can be expanded to -48 V

100 AH through connecting the upper and the lower battery groups in parallel.

When the -48 V 92 AH batteries are configured,

they can be expanded to -48 V 184 AH throughconnecting the upper and the lower battery groups

in parallel.


15/23


Door Status Sensor The APM30 power cabinet, APM30 battery cabinet, and APM30 transmission

cabinet use the same type of door status sensor.

Internal DDF Twisted Pair DDF

The twisted pair DDF provides the access for eight twisted pair E1s. It is 1U in height and does not provide the lightning protection function.


20/23


Battery The power cabinet can house 1 to 3 groups of -48 V 12 AH

batteries, which can form the -48 V 12 AH battery group system, the -48 V 24 AH system, or the -48 V 36 AH system. The details are as

follows:

The -48 V 12 AH or -48 V 24 AH battery group is installed in the 3 U

space at the bottom, and the remaining 5 U space can be used to install the

user devices.

The -48 V 36 AH battery group is installedin the 6 U space at the bottom, and the

remaining 2 U space can be used to install

the user devices.


21/23


Sensors Door Status Sensor

The door status sensor is made up of two parts, the magnet part and the switch

part.


22/23


Sensors Temperature Sensor

The temperature sensors of the APM30 consist of the air inlet temperature

sensor, internal ambient temperature sensor, and the air outlet temperature

sensor.
