Notes
Note 1: After reset the state machine is fixed to F0.
Note 2: This event reflects the case where a signal is received and the TE has not (yet) determined wether
Note 3: Bit- and frame-synchronisation achieved.
Note 4: Loss of Bit- or frame-synchronisation.
Note 5: Timer 3 (T3) is not implemented in the HFC-SP and must be implemented in software.
