Description: This “core” is actually two cores – an HDB3/HDB2/B3ZS Encoder that converts NRZ
data into P and N pulses according to ITU-T G.703, and a HDB3/HDB2/B3ZS Decoder
that converts P and N pulses into NRZ data according to ITU-T G.703.
Note: HDB2 and B3ZS are different names for the same encoding.
HDB3 is typically used to encode data at 2.048 (E1), 8.448 (E2) and 34.368Mb/s (E3)
B3ZS is typically used to encode data at 44.736Mb/s (T3)
