Please refer to the rack configuration figures above. Each of the hardware blocks mentioned are described
below:
2.3.1 AFEB
The AFEB (Antenna Front End Block) includes the AFEU (Antenna Front End Unit), the RXDU (Receive
Divider Unit), and the TFEU (Transmit Front End Unit). The RXDU and TFEU are only employed for base
stations with multiple carriers.
2.3.2 BCIN
The BCIN (BTS Communication Interconnection Network) includes the HIPA (High Speed IPC Processor
Board Assembly), the HINA (High Speed IPC Node Board Assembly), and the LITA/LIEA (Link Interface IPC
T1/E1 Assembly-D). The BCIN provides the BTS to BSC interface and performs packet routing for the Inter
Processor Communications (IPC) in the BTS.
2.3.3 BCMB
The BCMB (BTS Control and Maintenance Block) includes the SCPA (Subsystem Control Processor Board
Assembly), the CSAA (Cell Site Alarm Assembly), the GPSR (Global Positioning System Receiver), and the
PCU-B (Power Converter Unit in the BCIN block). The BCMB performs the following major functions:
