Bit 9: BERT Enable (BERTE). See Section 8.5.
Bit 8: BERT Direction (BERTD). See Section 8.5.
Bit 7: STS-1 Scrambling Disable (SCRD). This bit controls STS-1 scrambling when AIS-L is generated in STS-1
mode. See Section 8.2.3.
Bit 4: AIS Type (AIST). See Section 8.2.4.
Bit 3: Transmit AIS (TAIS). The type of AIS signal depends on the LIU mode (DS3, E3, or STS-1) and the
configured AIS type. See Section 8.2.4.
Bit 2: Loopback Select (LBS). This bit affects the function of the loopback mode (LBM[1:0]) bits.
Bits 1 and 0: Loopback Mode (LB[1:0]). These bits enable loopbacks. The effect of the LB = 11 decode is
controlled by the LBS configuration bit. See Section 8.6.

0 = disable the BERT pattern generator (the pattern detector is always enabled)
1 = enable the BERT pattern generator (the pattern detector is always enabled)
0 = line direction (transmit to receive)
1 = system direction (receive to transmit)
0 = Perform scrambling
1 = Do not perform scrambling
0 = Unframed all ones
1 = Framed DS3 AIS (DS3 mode), unframed all ones (E3 mode), or AIS-L (STS-1 mode)
0 = transmit normal data
1 = transmit AIS signal
00 = No loopback
01 = Diagnostic loopback (DLB)
10 = Line loopback (LLB)
11 (LBS = 0) = Line loopback (LLB) and diagnostic loopback (DLB) simultaneously
11 (LBS = 1) = Analog loopback (ALB)
