All transmit pulse shaping to meet E1 and T1 transmission standards is done
internally, eliminating the need for external shaping circuitry. The pulse shape
block receives bipolar NRZ transmit data, produces a set of eight 5-bit values
which define the pulse shape, and converts the shape values into an analog pulse
using a DAC.
