1 Overview1.1 BBU3900 Functions
A BBU3900 is a baseband unit that performs the following functions:
l Provides S1 ports for communication between an E-UTRAN NodeB (eNodeB) and anMME/S-GW, and X2 ports for communication between eNodeBs. E-UTRAN is short for
evolved universal terrestrial radio access network.
l Provides common public radio interface (CPRI) ports for communication with RRUs andprocesses uplink and downlink baseband signals. RRU is short for remote radio unit.
l Manages the eNodeB through operation and maintenance (OM) and signaling messageprocessing.
l Provides an OM channel to the local maintenance terminal (LMT) or M2000. iManagerM2000 (M2000). The M2000 is an integrated OM system designed by Huawei.
l 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.
1.2 Exterior of the BBU3900The BBU3900 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.
Figure 1-1shows the exterior of the BBU3900.
