8.10.1.9 Initialization
Once the IBS finishes the downloading, the system starts the initialization.
The system synchronizes the signals of the IBSs so that handovers are possible. The system selects
the T0, T2, or CPU main board clock as the source.
Then the system sends the following data:
•
Fixed part capabilities (Full slot, frequency control, page repetition, setup on dummy, basic A field
setup): value sent = 0x007910
•
Line length: Short line
•
Frequency plan (2 bytes)
Some countries have shifted DECT frequencies. In order to be compatible with all frequency bands in
the different countries, 4 types of initialization of frequency plans are available:
Europe, Latin America, The United-States and China.

By default, all frequencies used
