The RFU performs modulation and
demodulation between baseband signals and
RF signals, processes data, and combines and
divides signals.
The BBU3900 processes the baseband signals
and enables interaction between the basestation and the base station controller.
The WMPT has the following functions:
l Providing Operation and Maintenance (OM) functions such as configuration management,
equipment management, performance monitoring, signaling processing, and active/
standby switchover and providing OM channels connected to the OMC (LMT or M2000)l Providing the reference clock
l Processing signaling and managing resources for other boards in the BBU3900
l Providing USB ports, one of which facilitates automatic BBU3900 upgrading when a US
disk is inserted during software installation and data configuration
l Providing four E1s/T1s which support ATM and IP protocols
l Providing one FE electrical port and one FE optical port which support the IP proto
l Supporting cold backup

The UTRP has the following functions:
l The UTRP2 provides two 100M/1000M Ethernet optical ports, performs functions of the
MAC layer, receives and transmits data on Ethernet links, and analyzes the MAC
address.
l The UTRP3 provides eight E1s/T1s and performs inverse multiplexing and
demultiplexing
on a single ATM cell flow on the eight E1/T1 links.
l The UTRP4 provides eight E1s/T1s, frames and deframes HDLC frames, and allocates
andcontrols the 256 HDLC timeslot channels.
l The UTRP6 supports one unchannelized STM-1/OC-3 port.

l Implements the direct frequency conversion technique in the transmit channel. The
baseband signals are modulated to WCDMA RF signals. After being filtered andamplified
or being combined, the RF signals are transmitted through the duplex filter to the
antenna
for radio transmission.
l Receives UL RF signals from the antenna system and then down-converts the received
signals to IF signals. After amplification, analog-to-digital conversion, digital
downconversion,
matched filtering, automatic gain control (AGC), the IF signals are sent to the
BBU for further processing.
l Implements power control and Voltage Standing Wave Ratio (VSWR) detection
l Provides reverse power detection
l Provides frequency synthesis and loopback test
