Programming Information
IDT82P2288
Bit Name
= 0: More than 60 zeros are detected in a 40ms fixed window and this status persists for Mx40ms. Here ‘M’ is decided by the AISCTH[7:0] bits
(b7~0, T1/J1-0C1H,...).
= 1: Less than 61 zeros are detected in a 40ms fixed window and this status persists for Nx40ms. Here ‘N’ is decided by the AISDTH[7:0] bits
(b7~0, T1/J1-0C0H,...).
The Yellow Alarm is detected when the frame is synchronized.
In T1 SF / SLC-96 format:
= 0: More than 76 ‘One’s are detected on the Bit 2 of each channel during a 40ms fixed window and this status persists for Mx40ms. Here ‘M’ is
decided by the YELCTH[7:0] bits (b7~0, T1/J1-0BFH,...).
= 1: Less than 77 ‘One’s are detected on the Bit 2 of each channel during a 40ms fixed window and this status persists for Nx40ms. Here ‘N’ is
decided by the YELDTH[7:0] bits (b7~0, T1/J1-0BEH,...).
In T1 ESF format:
= 0: Less than 8 ‘0xFF00’ (MSB first) are detected on the DL bits during a 40ms fixed window and this status persists for Mx40ms. Here ‘M’ is
decided by the YELCTH[7:0] bits (b7~0, T1/J1-0BFH,...).
= 1: More than 7 ‘0xFF00’ (MSB first) are detected on the DL bits during a 40ms fixed window and this status persists for Nx40ms. Here ‘N’ is
decided by the YELDTH[7:0] bits (b7~0, T1/J1-0BEH,...).
In T1 DM format:
= 0: More than 3 ‘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. Here ‘M’
is decided by the YELCTH[7:0] bits (b7~0, T1/J1-0BFH,...).
= 1: Less than 4 ‘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. Here ‘N’ is
decided by the YELDTH[7:0] bits (b7~0, T1/J1-0BEH,...).
In J1 SF format:
= 0: More than 3 zeros are detected on the F-bit of the 12nd frame during a 40ms fixed window and this status persists for Mx40ms. Here ‘M’ is
decided by the YELCTH[7:0] bits (b7~0, T1/J1-0BFH,...).
= 1: Less than 4 zeros are detected on the F-bit of the 12nd frame during a 40ms fixed window and this status persists for Nx40ms. Here ‘N’ is
decided by the YELDTH[7:0] bits (b7~0, T1/J1-0BEH,...).
In J1 ESF format:
= 0: More than 2 zeros are detected on the DL bits during a 40 ms fixed window and this status persists for Mx40 ms. Here ‘M’ is decided by the
YELCTH[7:0] bits (b7~0, T1/J1-0BFH,...).
= 1: Less than 3 zeros are detected on the DL bits during a 40 ms fixed window and this status persists for Nx40 ms. Here ‘N’ is decided by the
YELDTH[7:0] bits (b7~0, T1/J1-0BEH,...).
= 0: The in SF / ESF / T1 DM / SLC-96 synchronization status persists for Mx120ms. Here ‘M’ is decided by the REDCTH[7:0] bits (b7~0, T1/J1-
0BDH,...).
= 1: The out of SF / ESF / T1 DM / SLC-96 synchronization status persists for Nx40ms. Here ‘N’ is decided by the REDDTH[7:0] bits (b7~0, T1/J1-
0BCH,...).
