NATUSE
The NATUSE bit reflects the state of the extracted National Use bit (bit 12 of the frame in
G.751 E3 mode).
TIMEMK
The TIMEMK bit reflects the state of the Timing Marker bit (bit 8 of the G.832 Maintenance
and Adaptation byte).
PTYPE[2:0]
The PTYPE[2:0] bits reflect the state of the Payload Type bits (bits 3,4,5 of the G.832
Maintenance and Adaptation byte). These bits are not latched and should be read 2 or three
times in rapid succession to ensure a coherent binary value.
FEBE
The FEBE bit reflects the state of the FEBE indication bit (bit 2 of the G.832 Maintenance
and Adaptation byte).
FERF
The FERF bit reflects the value of the Far End Receive Failure indication bit (bit 1 of the
G.832 Maintenance and Adaptation byte), or the value of the RAI bit (bit 11 of the frame in
G.751) when the value has been the same for either three or 5 consecutive frames.
