T1/J1 Yellow Clear Threshold (0BFH, 1BFH, 2BFH, 3BFH, 4BFH, 5BFH, 6BFH, 7BFH)
YELCTH[7:0]:
window and this status persists for Mx40ms; in T1 ESF format, the Yellow alarm is cleared when less than 8 ‘0xFF00’ (MSB first) are detected on the
sliding DL bits during a 40ms fixed window and this status persists for Mx40ms; in T1 DM format, the Yellow alarm is cleared when more than 76
‘One’s are detected on the Y bit (Bit 6 in each CH 24) during a 40ms fixed window and this status persists for Mx40ms; in J1 SF format, the Yellow
alarm is cleared when more than 3 ‘One’s are detected on the F-bit of the 12nd frame during a 40ms fixed window and this status persists for Mx40ms;
in J1 ESF format, the Yellow alarm is cleared when more than 2 zeros are detected on the DL bits during a 40ms fixed window and this status persists
for Mx40ms. The value of the ‘M’ are all decided by these bits.
