iii. Power Amplifier Unit (PAU)
The PAU amplifies the power of the radio carrier to provide the BS
equipment with sufficient transmission power.
In band GSM900 or EGSM900, ZXG10 OB06 features a transceiver
unit with an output power of 80 W. The unit consists of two
modules: STRG and SPAG: The former fulfills the functions of the
TPU and RCU parts, while the latter accomplishes the functions of
the PAU. The SPAG and STRG form the TRM of the GSM900 system
or the EGSM900 system.
3. Antenna Equipment Module (AEM)
The AEM accomplishes functions of duplex and distribution of air
signals. ZXG10 OB06 provides a Combiner Distribution Unit (CDU) and
a Combiner Extension Unit (CEU):
i. The CDU supports one 2-in-1 combiner unit and one 1-to-4
distribution unit. It has two low noise amplifiers with extended
receiving output and one built-in duplexer.
ii. The CEU supports two 1-to-2 power distribution units and two 2-in-
1 combiner units.
The AEM can provide the ZXG10 OB06 (V1.0) with different
configurations through combinations.
4. Backplane Transmission Module (BTM)
The BTM is responsible for transmitting messages between the CMM,
TRM and AEM and at the same time provides interfaces for inputting
and outputting external signals.
5. Transmission Management Module (TMM)
The TMM can be a product manufactured by a third party. In ZXG10
OB06 there is a standard 19-inch 3U-high shelf for accommodating
transmission devices such as SDH and microwave.
6. Heat Exchanger (HEX)
The HEX is composed of four key components, namely, internal
circulation fan, external fan, heat exchanging chip and heater. The HEX
provides a function of dissipating heat in case of high temperature and
heating in case of low temperature, so that suitable temperature will
be ensured in the cabinet for normal operation of the system.
7. Power Module (PWM)
The PWM accomplishes lightning protection and rectification/filtration
of AC power: It outputs AC 220 V power to the heat exchanger and the
maintenance socket; converts AC power to DC –48 V power for the
CMM, TRM, TMM and heat exchanger, and provides a function of
overload/short circuit protection.
Software Architecture
In software design, the ZXG10 OB06 (V1.0) adopts modular and
hierarchical concepts to facilitate development and maintenance.
