Bit 15: Nibble Align Disable (NAD). This bit is used to disable the nibble alignment of the transmit ATM cells in
direct mapped DS3 or E3 G.832 framing modes. It must be set when in DS3 M23 mode and the C-bits are used for
ATM payload.
Bits 14 to 12: Payload AIS Select [2:0] (PAIS[2:0]). This bit controls when an unframed all ones signal is forced
on the receive data path after the receive framer and payload loopback mux. Default: Payload AIS always sent.
Bits 11 to 10: Line AIS Select [1:0] (LAIS[1:0). These bits control when a DS3 framed AIS or an unframed all
ones signal is to be transmitted on TPOSn/TNEGn and/or TXPn/TXNn. The signal on TPOSn/TNEGn can be AMI
or unipolar. This signal is sent even when in diagnostic loopback and always over-rides signals from the framers.
Default: AIS sent if DLB is enabled.
