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 20

QRSS Generation
The XRT83SH38 can transmit a QRSS random sequence to a remote location from TTIP/TRING. The
polynomial is shown in
Table 11
.
4.5.3
T1 Short Haul Line Build Out (LBO)
The short haul transmitter output pulses are generated using a 7-Bit internal DAC (6-Bit plus the MSB sign bit).
The line build out can be set to interface to five different ranges of cable attenuation by programming the
appropriate channel register. The pulse shape is divided into eight discrete time segments which are set to
fixed values to comply with the pulse template. To program the eight segments individually to optimize a
special line build out, see the arbitrary pulse section of this datasheet. The short haul LBO settings are shown
in
Table 12
