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 DS26521
to be integrated for 200ms.
Bit 0: Receive-Side D4 Remote Alarm Select (RD4RM).
