Page 5 of 22 1 Overview 1.1 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 an MME/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 and  processes uplink and downlink baseband signals. RRU is short for remote radio unit. l   Manages the eNodeB through operation and maintenance (OM) and signaling message  processing. l   Provides an OM channel to the local maintenance terminal (LMT) or M2000. iManager M2000 (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 BBU3900 The 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 1-1 shows the exterior of the BBU3900.
