4.2 Network Synchronization Message Flow
The outdoor SPI-2210 uses GPS for the system synchronization. The UCCM of the MMA-
S, which is the GPS reception module, creates the clock with the clock information
received from a GPS and then distributes the clock to each hardware module in the outdoor
SPI-2210.
