0 = Normal (line) operation. Receive BERT port receives data from the receive framer.
1 = System (backplane) operation. Receive BERT port receives data from the transmit path. The transmit
path enters the receive BERT on the line side of the elastic store (if enabled).
0 = The receive BERT will not clock data from the F-bit position (framed).
1 = The receive BERT will clock data from the F-bit position (unframed).
0 = Receive BERT port is not active.
1 = Receive BERT port is active.
