TMUX_FORCEC2DEF[2:0] will force path payload label mismatch defects on those conditions that are shown in
Table 536.
The continuous N-times detection counter(s) will be reset to 0 upon the transition of the framer into the out of frame
state.
RDI-P Detection. A remote defect indication-path (RDI-P) signal indicates to STS path terminating equipment
(PTE) that its peer STS PTE has detected a defect on the signal that it originated. The TMUX supports a 1-bit
RDI-P code as well as a 3-bit enhanced RDI-P code; the mode is selectable using the TMUX_REPRDI_MODE
(Table 105 on page 97). If TMUX_REPRDI_MODE = 0, then the 1-bit code is supported, and if
TMUX_REPRDI_MODE = 1, then the 3-bit enhanced path RDI code is supported.
The TMUX monitors for a 1-bit RDI-P code in G1[3] or a 3-bit enhanced remote defect indication (RDI-P) condition
in G1[3:1]. The current value of the path RDI state will be detected after a number of consecutive occurrences
determined by the value in TMUX_CNTDRDIP[3:0] (Table 109 on page 101). The current value(s) will be stored in
TMUX_RDIPMON[1—3][2:0]] (Table 114 on page 103), for nonenhanced RDI-P mode, and the current value(s)
will be stored in TMUX_RDIPMON[1—3][2:0], for enhanced RDI-P mode. Any change to
TMUX_RDIPMON[1—3][2:0] will be reported in TMUX_RRDIPD[1—3] with interrupt mask
bits,TMUX_RRDIPM[1—3] (Table 97 on page 91).
The continuous N-times detection counter(s) will be reset to 0 upon the transition of the framer into the out of frame
state.
