HDB3/B8ZS Encoder
In single rail mode, the LIU can encode the TPOS input signal to AMI or HDB3/B8ZS data. In E1 mode and
HDB3 encoding selected, any sequence with four or more consecutive zeros in the input will be replaced with
000V or B00V, where "B" indicates a pulse conforming to the bipolar rule and "V" representing a pulse violating
the rule. An example of HDB3 encoding is shown in
Table 7
. In T1 mode and B8ZS encoding selected, an
input data sequence with eight or more consecutive zeros will be replaced using the B8ZS encoding rule. An
example with Bipolar with 8 Zero Substitution is shown in
Table 8
.
