for the wires connected to the monitoring ports on this UPEU are the same as those for the wires connected

to the monitoring ports on the UEIU.

The EMU and EMUA are used for environment monitoring indoors and outdoors respectively.

The EMU and EMUA enable the monitoring of analog values and Boolean signals with the portfor monitoring analog inputs, port for detecting the Boolean inputs, and port for controlling the

external Boolean outputs.

l When the base station is deployed indoors, the EMU is configured for monitoring the analog

values and Boolean signals. For details about the monitoring ports on the EMU, see

HUAWEI QCKG1EMU User Guide.

l When the base station is deployed outdoors, the EMUA is configured for monitoring the

analog values and Boolean signals. For details about the monitoring ports on the EMUA,

DIP Switch

The WMPT has two DIP switches: SW1 for setting the E1/T1 working mode and SW2 for setting

the protection grounding for the E1/T1 cables receiving 4-way signals. Figure 4-5shows the

DIP switches on the WMPT.

WBBP

The WCDMA Baseband Process Unit (WBBP) of the BBU3900 processes baseband signals.

Panels

The WBBP has three types of panels, as shown in Figure 4-6, Figure 4-7and Figure 4-8.

Functions

The WBBP has the following functions:

l Provides the CPRI interface for communication between the BBU and the RRU or RFU,

and supports the CPRI interface in 1+1 backup mode

l Processes uplink and downlink baseband signals

l The WBBPd supports interference cancellation (IC) within the board.

l When installed in slot 2 or slot 3, the WBBPd supports the IC function of uplink data.

Table 4-6describes the specifications of the WBBP.

LEDs

The WBBPa and WBBPb provide three LEDs indicating the status of the SFP links, and the

LEDs are positioned below the SFP ports. The WBBPd provides six LEDs indicating the status

of the SFP links, and the LEDs are positioned above the SFP ports.
