1.1 BBU3900&BBU3910 Functions
A BBU3900&BBU3910 is a baseband unit that performs the following functions:
Provides S1 ports for communication between an E-UTRAN NodeB (eNodeB) and an
MME/S-GW, and X2 ports for communication between eNodeBs. E-UTRAN is short for
evolved universal terrestrial radio access network.
Provides common public radio interface (CPRI) ports for communication with RRUs and
processes uplink and downlink baseband signals. RRU is short for remote radio unit.
Manages the eNodeB through operation and maintenance (OM) and signaling message
processing.
Provides an OM channel to the local maintenance terminal (LMT) or U2000. iManager
U2000 (U2000). The U2000 is an integrated OM system designed by Huawei.
Provides clock ports for clock synchronization, alarm monitoring ports for environment
monitoring, and a Universal Serial Bus (USB) port for commissioning using a USB flash
drive. The security of the USB port is ensured by encryption.
Compared with the BBU3900, the BBU3910 has enhanced backplane switching capabilities:
In the BBU3900, no direct route is available between slots 0, 1, 4, and 5, and data
between them must be transferred by slot 2 or 3. In the BBU3910, however, data can be
directly exchanged between slots 0 through 5.
Figure 1-1 shows the slot connections in the BBU3900 and BBU39010.

The backplane switching bandwidth for each pair of directly-connected slots in the
BBU3910 is almost twice that in the BBU3900.
1.2 Exterior of the BBU3900&BBU3910
The BBU3900&BBU3910 is a case measuring 19 inch wide and 2 U high. It can be installed
indoors, such as an office building or residence, or be installed in a cabinet with surge
protection in an outdoor place, such as a basement, balcony, corridor, or garage.
