2.2.2 Pulse Shaper
The pulse shaper converts the two digital (clocked) positive and negative pulses
into a single analog three-level Alternate Mark Inversion (AMI) pulse. The pulses
are in Return to Zero (RZ) format, meaning that all positive and negative pulses
have a duration of the first half of the symbol period.
For the E3 rate (E3MODE = 1), the AMI pulse is a full-amplitude,
square-shaped pulse with very little slope.
For DS3/STS-1 rates, a pulse-shaper block is used to shape the transmit
waveform and reduce its high-frequency energy content. This ensures that the
transmit pulse template is met at the cross-connect block, which follows 0
