5.3.4
The analog transmitter transforms the unipolar bit stream to ternary (alternate bipolar)
return to zero signals of the appropriate programmable shape. The unipolar data is
provided by pin XDI and the digital transmitter.
Similar to the receive line interface three different data types are supported:

Selection between B8ZS or simple AMI coding with zero code suppression (B7
stuffing) is provided. B7 stuffing may be disabled on a per time slot basis (Clear
Channel capability). Selected by FMR0.XC1/0 and LIM1.DRS = 0.
100 % duty cycle and with programmable polarity. Line coding is done in the same
way as in the ternary interface. Selected by FMR0.XC1=1 and LIM1.DRS = 1.
duty cycle to a fibre optical interface. Clocking off data is done with the rising edge of
the transmit clock XCLK (1544 kHz) and with a programmable polarity. Selection is
done by FMR0.XC1...0 = 00 and LIM1.DRS = 1.
( 1 %) [ ]
Single rail data is converted into a ternary signal which is output on pins XL1 and XL2.
