Line code conversion inputs the binary bit pattern and converts the transition
from 1 to 0 or 0 to 1 to a positive or negative pulse. Table 3–39 lists the standard
defined code conversions.

Number ofsuccessive 0: 0
B3ZS, HDB3
(High Density Bipolar 3)
Polarity ofthe last pulse: Negative
Number ofsuccessive 0: 0
Number ofB pulse: 1

Initial level: 0,
First output nonzero level: 1
The standard-defined isolated pulse is used. You do not need to set a pulse.
When the Line Code is a AMI standard (ITU–T E1, E2, E3, T1.102 DS1, DS1A,
DS1C, DS2, DS3, STS–T), an user defined waveform file can be used as an
isolated pulse. The length of isolated pulse has no restriction.
