Online Software Loading

It supports the ZXG10-OB06 (V1.0) software online loading by BSC.
Figure 62 shows the software loading process.

CMM software
FUC software
CHP software
All software versions are downloaded into the CMM's FLASH memory from
BSC. The CMM validates the versions, and loads the software in FUC when
it finds any difference with the TRM software.
The TRM software is stored in the FLASH memory on the FUC board. After
DSP restarts, the FUC software loads the CHP software to the CHP and CIP
through the HPI interface.
Below is the software loading procedure:
1. The CMM sends the 'software loading initialization' message to FUC.
2. The FUC returns the 'software loading initialization finished' message to
CMM.
3. CMM divides the software versions into message segments and sends
FUC segment by segment.
4. When all software data are sent, the CMM send the 'software loading
finished' message to FUC.
5. The FUC returns the 'software loading finished acknowledgment'
message to CMM.

Ultra-distance Coverage

Ultra-distance coverage refers to coverage by a BTS with a cell-radius
greater than 35 km, which is according to the GSM standard.
According to the GSM protocol, the maximum access-radius of GSM
system is 35 km, and the corresponding time advance (TA) is 63. This
limit is made because, under normal conditions, and in a 900 MHz
