ATAOS (Automatic Transmit All Ones)
If ATAOS is selected by programming the appropriate global register, an AMI all ones signal will be transmitted
for each channel that experiences an RLOS condition. If RLOS does not occur, the ATAOS will remain inactive
until an RLOS on a given channel occurs. A simplified block diagram of the ATAOS function is shown in
FIGURE 33. SIMPLIFIED BLOCK DIAGRAM OF THE ATAOS FUNCTION

Network Loop Up Code
By setting the LIU to generate a NLUC, the transmitters will send out a repeating "00001" pattern. The output
waveform is shown in Figure 34.

4.5.3
Network Loop Down Code
By setting the LIU to generate a NLDC, the transmitters will send out a repeating "001" pattern. The output
waveform is shown in Figure 35.
