Appendix C: B3ZS/HDB3 Encoding
The definitions of B3ZS and HDB3 encoding, according to the ITUT-G.703 standard,
are:
!
!
NOTE:
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.
