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 DS26518
to be integrated for 200ms.
Bit 0: Receive-Side Remote Alarm Select (RRAIS)
