Bit 7 (T1 Mode): Transmit HDLC-256 Mode Select (THMS)
Bit 7 (E1 Mode): Transmit HDLC-256 Mode Select (THMS)
Bit 6: Transmit HDLC-256 Enable (THEN)
Bit 2: Transmit BERT Port Direction Control (TBPDIR)
Bit 1: Transmit BERT Port Framed/Unframed Select (TBPFUS) (T1 Mode Only)
Bit 0: Transmit BERT Port Enable (TBPEN)
0 = Transmit HDLC-256 assigned to time slots.
1 = Transmit HDLC-256 assigned to FDL bits.
0 = Transmit HDLC-256 assigned to time slots.
1 = Transmit HDLC-256 assigned to the Sa bits.
0 = Transmit HDLC-256 is not active.
1 = Transmit HDLC-256 is active.
0 = Normal (line) operation. Transmit BERT port sources data into the transmit path.
1 = System (backplane) operation. Transmit BERT port sources data into the receive path (RSERn). In this
mode, the data from the BERT is muxed into the receive path.
0 = The DS26518’s transmit BERT will not clock data into the F-bit position (framed).
1 = The DS26518’s transmit BERT will clock data into the F-bit position (unframed).
0 = Transmit BERT port is not active.
1 = Transmit BERT port is active.
