window and this status persists for Nx40ms; in T1 ESF format, the Yellow alarm is declared when more than 7 ‘0xFF00’ (MSB first) are detected on the
sliding DL bits during a 40ms fixed window and this status persists for Nx40ms; in T1 DM format, the Yellow alarm is declared when less than 77
’One’s are detected on the Y bit (Bit 6 in each CH 24) during a 40ms fixed window and this status persists for Nx40ms; in J1 SF format, the Yellow
alarm is declared when less than 4 ’One’s are detected on the F-bit of the 12nd frame during a 40ms fixed window and this status persists for Nx40ms;
in J1 ESF format, the Yellow alarm is declared when less than 3 zeros are detected on the DL bits during a 40ms fixed window and this status persists
for Nx40ms. The value of the ‘N’ are all decided by these bits.
