NATUSE

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 3 times in rapid succession to ensure a coherent binary

value.

FEBE:

The FEBE bit reflects the state of the Far End Block Error 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

Remote Alarm indication bit (bit 11 of the frame in G.751) when the value has

been the same for either 3 or 5 consecutive frames.
