BBU3900 in a Standard 19-Inch Cabinet

Application scenario 1

Launch 3G services on the basis of a 2G site

Benefit of this Application Scenario:

Can reside in any standard 19-inch-wide and 2-U-high cabinet

Can be installed on the metal pole and close to the antenna

The BBU3900 and RRU can share the power supply and antenna systems of the 2G network

Enables operators to launch 3G services on the existent 2G network at a very low cost

53/72


The five-meter-long AISG multi-wire cable connects the RRU3804/SRXUto the Remote Control Unit (RCU). If both RRU3804 and SRXU are installed,

the AISG multi-wire cable only connects the SRXU and the RCU. This

cable is optional

One end of the AISG multi-wire cable is a waterproof DB9 connector, and

the other end is a standard AISG female connector

54/72


When the distance between the RCU and the RRU3804/SRXU is longerthan 5 m, the AISG multi-wire cable is not long enough to cover the

distance and the AISG extension cable is used. The AISG extension cable

is 15 m long

One end of the AISG extension cable is a standard AISG male connector,

and the other end is a standard AISG female connector

The RF jumper of the RRU3804/SRXU is of two types

Antenna jumper: transmits and receives RF signals. Both

ends of the antenna jumper have DIN connectors

Interconnect jumper: transmits RF signals between

two RRU3804s/SRXUs.

The interconnect jumper is optional, depending on the

site configuration. The interconnect jumper is 2 m

long, and both ends have 2W2 connectors

The 2W2 connectors at the two ends of the

interconnect jumper are linked to the ports labeled
