0 = Receive HDLC-256 assigned to time slots
1 = Receive HDLC-256 assigned to FDL bits
0 = Receive HDLC-256 assigned to time slots
1 = Receive HDLC-256 assigned to the Sa bits
0 = Receive HDLC-256 is not active.
1 = Receive HDLC-256 is active.
0 = Normal (line) operation. Rx BERT port receives data from the receive framer.
1 = System (backplane) operation. Rx 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 DS26518’s receive BERT will not clock data from the F-bit position (framed).
1 = The DS26518’s receive BERT will clock data from the F-bit position (unframed).
0 = Receive BERT port is not active.
1 = Receive BERT port is active.
