The Transmit FDL register (T1TFDL) contains the Facility Data Link (FDL) information that is to be inserted on a
byte basis into the outgoing T1 data stream. The LSB is transmitted first. In D4 mode, only the lower six bits are
used.
Bit 7: Transmit FDL Bit 7 (TFDL7). MSB of the transmit FDL code.
Bit 6: Transmit FDL Bit 6 (TFDL6).
Bit 5: Transmit FDL Bit 5 (TFDL5).
Bit 4: Transmit FDL Bit 4 (TFDL4).
Bit 3: Transmit FDL Bit 3 (TFDL3).
Bit 2: Transmit FDL Bit 2 (TFDL2).
Bit 1: Transmit FDL Bit 1 (TFDL1).
Bit 0: Transmit FDL Bit 0 (TFDL0). LSB of the transmit FDL code.
