Facility Data Link
The received ANSI FDL status byte, register FDL_SR3, has the following format.
Table 38. Receive ANSI Code
Receive ANSI Performance Report Messages (PRM)
As defined in ANSI T1.403, the performance report messages consist of 15 bytes, starting and ending with an
HDLC flag. The receive framer status information consists of four pairs of octets, as shown in Table 39. Upon
detection of the PRM message, the receive FDL extracts the 13 bytes of the PRM report field and stores it in the
receive FDL FIFO along with the status of frame byte.
Table 39. Performance Report Message Structure*
* The rightmost bit (bit 1) is transmitted first for all fields except for the 2 bytes of the FCS that are transmitted
The definition of each PRM field is shown in Table 40, and octet content is shown in Table 41.
