TFRA08C13 OCTAL T1/E1 Framer
Facility Data Link
Transmit Facility Data Link Interface
The FDL interface of the transmit framer is shown in Figure 33, indicating the priority of the FDL sources.
The remote frame alarm, enabled using register FRM_PR27, is given the highest transmission priority by the trans-
mit framer.
The ANSI T1.403-1995 bit-oriented data link message transmission is given priority over performance report mes-
sages and the automatic transmission of the performance report messages is given priority over FDL HDLC trans-
mission. Idle code is generated by the FDL unit when no other transmission is enabled.
The FDL transmitter is enabled by setting register FDL_PR1 bit 3 to 1.
Transmit ANSI T1.403 Bit-Oriented Messages (BOM)
When the ANSI BOM mode is enabled by setting register FDL_PR10 bit 7 to 1, the transmit FDL can send any of
the ANSI T1.403 ESF bit-oriented messages automatically through the FDL bit in the frame.
The transmit ESF FDL bit-oriented messages of the form 111111110X
ANSI FDL parameter register FDL_PR10 bit 0—bit 5. The ESF FDL bit-oriented messages will be repeated while
register FDL_PR10 bit 7 (FTANSI) is set to 1.
