and the signaling bits on Framer 12 & 24 are recognized as ‘B’. Only the signaling bits A & B are saved in the Extracted Signaling Data/Extract Enable

Extract Enable register.
Programming Information
IDT82P2281
Bit Name
Default
Bit No.
Type
= 0: Disable the manual signaling freezing.
= 1: Manually freeze the signaling data in the A,B,C,D bits (b3~0, T1/J1-ID-01~18H) as the previous valid value.
= 0: Disable the signaling de-bounce.
= 1: Enable the signaling de-bounce. That is, the A,B,C,D bits (b3~0, T1/J1-ID-01~18H) are updated only if 2 consecutive received AB/ABCD
= 0: Disable the interrupt on the INT pin when any of the COSI bits (T1/J1-0D8H & T1/J1-0D7H & T1/J1-0D6H) is ‘1’.
= 1: Enable the interrupt on the INT pin when any of the COSI bits (T1/J1-0D8H & T1/J1-0D7H & T1/J1-0D6H) is ‘1’.
This bit is valid only in the ESF and SLC-96 format.
= 0: The extracted signaling bits are in 4 states signaling, i.e., the signaling bits on Framer 6 & 18 of a signaling multi-frame are recognized as ‘A’
= 1: The extracted signaling bits are in 16 states signaling, i.e., four signaling bits A, B, C & D are all saved in the Extracted Signaling Data/
