The pointer interpreter transitions into the LOP state based on the following conditions:
The pointer interpreter will transition out of the LOP state based on the following conditions:
The pointer interpreter will transition into the AIS state based on the following conditions:
The pointer interpreter will transition out of the AIS state based on the following conditions:
The pointer interpreter will transition into the NDF state based on the following condition:
The pointer interpreter will transition out of the NDF state based on the following conditions:
The pointer interpreter will transition into the NORM state based on the following conditions:
— Continuous NDF. If NDF (1001, 0001, 1101, 1011, and 1000) is received in 8, 9, or 10 consecutive frames, as
— Invalid pointer values. If 8, 9, or 10 consecutive frames (determined by TMUX_CTDLOPCNT[1:0]) are received
— Following three consecutive frames with all ones in the H1 and H2 bytes, the pointer interpreter will transition
— Following three new consecutive, consistent, and valid pointers, the pointer interpreter will transition from the
— The pointer interpreter will not transition from the LOP state into the NDF state.
— Following three consecutive frames with all ones in the H1 and H2 bytes, AIS will be declared.
— Following three new consecutive, consistent, and valid pointers, the pointer interpreter will transition from the
— Following eight consecutive invalid pointers, the pointer interpreter will transition from the AIS state into the
— If NDF is enabled on the incoming H1 and H2 bytes, the pointer interpreter will transition from the AIS state
— If NDF is enabled on the incoming H1 and H2 bytes, the pointer interpreter will transition from the NORM,
— Continuous NDF. If NDF (1001, 0001, 1101, 1011, and 1000) is received for eight consecutive frames, the
— Following any three consecutive, consistent, and valid pointers, the pointer interpreter will transition from the
— Following three consecutive frames with all ones in the H1 and H2 bytes, the pointer interpreter will transition
— Following three new, consecutive, consistent, and valid pointers, the pointer interpreter will transition from the
— Following eight consecutive invalid pointers, the pointer interpreter will transition from the NDF state into the
— Following three new consecutive, consistent, and valid pointers, the pointer interpreter will transition into the
— Following any three consecutive, consistent, and valid pointers, the pointer interpreter will transition into the
