9.8.10 Unsuccessful Ring Sequence, Auto Ring Disabled
The following chart and diagram show an unsuccessful flow of a ring-event detection
because ringing is below the ring threshold level with no automatic power-mode change
(No_auto_ring = 1, RM = 1).
Figure 35 Unsuccessful Ring Sequence, No_auto_ring = 0
Note: RMR will not be ’1’
