Note: See
Bit 7: Transmit Japanese CRC-6 Enable (TJC)
Bit 6: Transmit F-Bit Pass Through (TFPT)
Bit 5: Transmit CRC Pass Through (TCPT)
Bit 4: Transmit Software Signaling Enable (TSSE). This function is enabled by TB7ZS (T1.TCR2.0).
Bit 3: Global Bit 7 Stuffing (GB7S). This function is enabled by TB7ZS (T1.TCR2.0).
Bit 2: Transmit B8ZS Enable (TB8ZS)
Bit 1: Transmit Alarm Indication Signal (TAIS)
Bit 0: Transmit Remote Alarm Indication (TRAI)
0 = Use ANSI/AT&T:ITU-T CRC-6 calculation (normal operation).
1 = Use Japanese standard JT–G704 CRC-6 calculation.
0 = F bits sourced internally.
1 = F bits sampled at TSERn (T1.TCR2.7 TFDLS must be programmed to 0).
0 = Source CRC-6 bits internally.
1 = CRC-6 bits sampled at TSERn during F-bit time.
0 = Do not source signaling data from the TS1–16 registers regardless of the SSIE1–4 registers. The
SSIE1–4 registers still define which channels are to have B7 stuffing performed.
1 = Source signaling data as enabled by the SSIE1–4 registers.
0 = Allow the SSIE1–4 registers to determine which channels containing all zeros are to be bit 7 stuffed.
1 = Force bit 7 stuffing in all zero byte channels of that port, regardless of how the SSIE1–4 registers are
programmed.
0 = B8ZS disabled.
1 = B8ZS enabled.
0 = Transmit data normally.
1 = Transmit an unframed all-ones code at TTIPn and TRINGn.
0 = Do not transmit remote alarm.
1 = Transmit remote alarm.
