FEAC[5:0]:

FEAC[5:0] contain the six bit code that is transmitted on the far end alarm

and control channel (FEAC). The transmitted code consists of a sixteen bit

sequence that is repeated continuously. The sequence consists of 8 ones

followed by a zero, followed by the six bit code sequence transmitted in order

FEAC0, FEAC1, ..., FEAC5, followed by a zero. The all ones sequence is

inserted in the FEAC channel when FEAC[5:0] is written with all ones.

Note: If configured for J2 transmission format (TFRM[1:0] is 10 binary) and

any of LCDEN, AISEN, OOFEN, LOSEN are set to logic 1 in the S/UNI-QJET

Data Link and FERF/RAI Control, FEAC[5:0] in this register must all be set to

logic 1 for proper RAI transmission upon detection of LCD, PHYAIS, LOF, or

LOS by the J2 FRMR. Otherwise, the BOC code configured by the FEAC[5:0]

bits of this register will be transmitted instead of the RAI.
