Bipolar Violation Detection
Page 68, Chapter 4.1.6, Receive Line Coding in E1 Mode
The HDB3 line code or the AMI coding is provided for the data received from the ternary
or the dual rail interface.
All code violations that do not correspond to zero substitution
rules are detected, resulting in an increment of the 16-bit code violation counter. If a bit
error causes a code violation that leads to a valid substitution pattern, this code violation
is neither detected nor counted and the substitution pattern is replaced by the
corresponding zero pattern.
In case of the optical interface a selection between the NRZ code and the CMI Code
(1T2B) with HDB3 or AMI postprocessing is provided. If CMI code is selected the receive
route clock is recovered from the data stream. The CMI decoder does not correct any
errors. In case of NRZ coding data is latched with the falling edge of signal RCLKI. The
HDB3 code is used along with double violation detection or extended code violation
detection (selectable by FMR0.EXZE). In AMI code all code violations are detected.
The
detected errors increment the code violation counter (16 bits length).
Page 127, Chapter 5.1.6, Receive Line Coding in T1/J1 Mode
The B8ZS line code or the AMI (ZCS, zero code suppression) coding is provided for the
data received from the ternary or the dual rail interface. All code violations that do not
correspond to zero substitution rules are
detected, resulting in an increment of the 16-bit
code violation
counter.
If a bit error causes a code violation that leads to a valid
substitution pattern, this code violation is neither detected nor counted and the
substitution pattern is replaced by the corresponding zero pattern.
The detected errors
increment the code violation counter (16 bits length).
