The ZXG10 OB06 hardware consists of a control and maintenance module 

(CMM), a transceiver module (TRM), an antenna feeder equipment 
module (AEM), a backplane transmission module (BTM), a power module 

and a heat exchanger.  

The hardware structure of the ZXG10 OB06 is shown in Figure 5.

The main functions of each module are as follows: 

1.  Controller & Maintenance Module (CMM)  

CMM implements Abis interface processing, BTS operation & 
maintenance, clock synchronization and generation, internal/external 

alarm collection and processing and other functions. 

2.  Transceiver Module (TRM)  

TRM controls and processes the radio channels; transmits and receives 
the radio channel data; modulates and demodulates the base-band 
signals on the radio carrier; and transmits and receives radio carriers 

in the GSM system. 
The TRM is divided into three units by function: 
i.  Transceiver Process Unit (TPU) 

The TPU implements all functions of base-band data processing of 

all duplex channels on a TDMA frame, and the conversion between 
the LapDm protocol and the LapD protocol. In addition, it provides 

GPRS data service, and supports CS1, CS2, CS3 and CS4 encoding 
modes. 

ii.  Radio Carrier Unit (RCU) 

The RCU modulates baseband signals to carrier signals and up-
converts frequency. At the same time, it down-converts the 

frequency of received carrier signals. In addition, it can control the 
power statically and dynamically in the downlink direction as 

required in GSM specifications.
