 * The size of the buffer is IDLE_TRACE_SIZE.
 *
 * The content is
 *
 * trace_type (uplink, downlink, event state, alr_event, rr_event)
 * Channel Type (SACCH, SDDCH, FACCH)
 * real system clock
 * State (DL states)
 * pending disc request
 * data (layer frame, eevnt strings, state)
 *
 * During IDLE mode (triggered by RX_PERIODIC_IND in ALR/TIL_main.c)
