Chapter 1
System Architecture
This chapter describes the background, the standards followed, major
functions, system features, working principles and the general structure of
both the software and hardware of the ZXG10 OB06 (V1.0).
System Introduction
System Background
ZXG10 OB06 is a high-capacity outdoor BTS for GSM, with a single cabinet
supporting six carriers at the maximum. It is to be installed outdoors,
integrating functions of transmission, power supply, environment
monitoring and temperature control in one system. It is applicable to the
following cases: The cost of a standard equipment room would be too high
in the site selected for it, for example, in the center of a city; there is no
equipment room in the site selected for it, for example, in the countryside
or in the remote areas of a city.
The availability of ZXG10 OB06 adds another product to the ZXG10-BTS
series and makes the ZXG10 system offer more flexible networking modes,
hence more powerful market competition edge.

processor, a transmission unit, a power unit and a heat exchanger. The
working principle of the system is as follows:
In the downlink direction, the ZXG10 OB06 (V1.0) receives data from BSC,
including voice and signaling data. Here, the signaling data are sent to the
control, operation & maintenance unit for processing. The voice data are
first sent to the base band processor for processing such as rate
conversion, encryption and interleaving, sent to the RF unit to be
modulated to high-frequency signals, and then finally transmitted through
the antenna feeder processor.
In the uplink direction, the antenna feeder processor receives the RF
signals from the MS, and sends them to the RF unit to convert them into
digital signals. Then, the signals are sent to the baseband processor for
rate conversion, decryption and de-interleaving. Finally, after being
converted to the code pattern suitable for long-distance transmission, the
signals are sent to the BSC through the Abis interface.
