FEBE[3:0]
These bits are used to hold the FEBE value to be inserted into the transmitted data stream. After insertion of these bits into
the FEBE location of the next possible frame, FEBE[3:0] will be reset. If the value written to these register bits can still be read
back, it just mean that the insertion has not taken place yet.
PRDI
This bit is used to insert remote defect indication (RDI) into the transmitted data stream.

G1[2:0]
These bits are inserted into the unused bit positions of G1 of every frame.
BIT POSITION
BIT POSITION
Normal operation. With the PRDI bit of G1 only affected by the setting of AUTOPRDI (Reg 01H, Bit 4) and the alarm
conditions.
The PRDI bit of G1 is set to 1.
