LCDEN
The LCDEN bit enables the receive-out-of-cell-delineation indication to automatically
generate a FERF indication (RAI in G.751 or J2 mode) in the transmit stream. This bit
operates regardless of framer selected (DS3, E3, or J2) but only in ATM mode. When
LCDEN is logic one, assertion of the LCD indication by the receive FIFO causes a
FERF/RAI to be transmitted by the transmitter for the duration of the LCD assertion. When
LCDEN is logic zero, assertion of the LCD indication does not cause transmission of a
FERF/RAI. Note: For the RAI to be automatically transmitted when in J2 format, the
FEAC[5:0] bits in the XBOC Code Register must all be set to logic one. If the XBOC FEAC
code is to be transmitted in J2 mode, LOSEN, OOFEN, AISEN, and LCDEN should all be set
to logic zero.
