Bit 4: Receive SLC-96 Synchronizer Enable (RSLC96). See Section
Bits 3 and 2: Out of Frame Select Bits (OOF[2:1]).
Bit 1: Receive RAI Integration Enable (RAIIE). The ESF RAI indication can be interrupted for a period not to
exceed 100ms per interruption (T1.403). In ESF mode, setting RAIIE will cause the RAI status from the DS26528
to be integrated for 200ms.
Bit 0: Receive-Side D4 Remote Alarm Select (RD4RM).

RAI detects when 16 consecutive patterns of 00FF appear in the FDL.
RAI clears when 14 or fewer patterns of 00FF hex out of 16 possible appear in the FDL.
RAI detects when the condition has been present for greater than 200ms.
RAI clears when the condition has been absent for greater than 200ms.
