Receive FEAC Channel Message Byte—If the incoming format is DS3-C Bit Parity, this
register contains the received byte from the bit-oriented Receive FEAC channel. The Receive
FEAC channel is only defined in DS3-C Bit Parity format. Receive FEAC message reception
is described in
received from the line. This byte is meaningless in DS3-M13/M23 and both E3 modes and
should be ignored.
Receive FEAC Channel Stack Message Byte—If the incoming format is DS3-C Bit Parity,
this register contains the FEAC stack received byte from the bit-oriented Receive FEAC
channel. Receive FEAC message reception is described in Far-End Alarm and Control
Channel Reception in the Receiver Operation section of the Functional Description chapter.
RxFEACS[D] is the first bit received and RxFEACS[5] is the last bit received from the line.
This byte is meaningless in DS3-M13/M23 and both E3 modes and should be ignored.
Receive FEAC Channel Stack Message Byte is Valid— Set on if RxFEACS [5:0] hold a valid
FEAC code word. For a detailed description, refer to Far-End Alarm and Control Channel
Reception sections.
Receive FEAC Channel Stack Has More Data—Set on if the current value of RxFEACS[5:0]
is not the last valid code word in the FEAC stack. For a detailed description, refer to Far-End
Alarm and Control Channel Reception sections.
