Appendix C: B3ZS/HDB3 Encoding
The definitions of B3ZS and HDB3 encoding, according to the ITUT-G.703 standard,
are:
NOTE:
Preliminary Information/Mindspeed Proprietary and Confidential
In DS3 mode of operation, when rail (bipolar) mode is enabled, B3ZS encoding is
performed. Each block of three successive zeros is replaced by 00V or B0V. The
choice of 00V or B0V is made so that the number of B pulses between consecutive
V pulses is odd.
Both in E3-G.751 and E3-832 modes of operation, when rail mode is enabled,
HDB3 encoding is performed. Each block of four successive zeros is replaced by
000V or B00V . The choice of 000V or B00V is made so that the number of B
pulses between consecutive V pulses is odd.

In the definitions, B represents an inserted pulse conforming to the B3ZS/HDB3 rule,
and V represents a violation.
