The Warm state is the condition during the 15 minute BTS warm up time. The A1 and A2 states are acquisition states when the DPLL is adjusting the19.6608 MHz frequency based on the available reference sources (RGPS or HSO). under normal operating conditions, the acquisition states last about 5 minutes. The TK state is the DPLL tracking state and is entered at the end of the acquisition states. The TK state is required for performing ATP.,GPS,DPLLSC300-1XDPLL_status Current source set to: GPS reference DPLL control task state: DPLL track.
