I know that the PDH technology is not very up-to-date. I just want to have elements of you about the justification mode that is generally used.
G.742 describes the positive justification for E2.
G.745 describes the positive/nul/negative justification for E2.
According to your knowledge, today, is it generally positive justification that is implemented in PDH, or positive/nul/negative justification?
Thanks for your opinion,
