Bit 7: u-Law or A-Law Digital Milliwatt Code Select (uALAW)
Bits 6 and 5: Transmit Bit Inversion (BINV[1:0])
Bit 4: Transmit Jammed Bit 8 Suppression Enable (TJBEN)
Bits 3: Transmit RAI Mode (TRAIM) (T1 Mode Only). Determines the pattern sent when TRAI (TCR1.0) is
activated in ESF frame mode only.
Bits 2 : Transmit AIS Mode (TAISM) (T1 Mode Only). Determines the pattern sent when TAIS (TCR1.1) is
activated.
Bits 1 and 0 : Transmit Code Length Definition Bits (TC[1:0]) (T1 Mode Only)

0 = u-law code is inserted based on TDMWEx registers.
1 = A-law code is inserted based on TDMWEx registers.
00 = No inversion.
01 = Invert framing.
10 = Invert signaling.
11 = Invert payload.
0 = No stuffing enabled.
1 = Jammed Bit 8 Suppression enabled. This forces bit 8 to a one as determined by TJBE1–4 registers
and bit 7 to a one in T1 signaling frames.
0 = Transmit normal RAI when TCR1.RAI = 1
1 = If T1 ESF mode, transmit RAI-CI (T1.403) when TCR1.RAI = 1
0 = Transmit normal AIS (unframed all ones) upon activation with TCR1.1.
1 = Transmit AIS-CI (T1.403) upon activation with TCR1.1.
