Bonjour,
I know that the PDH technology is not very up-to-date. I just want to have some elements from 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 the positive justification that is implemented in PDH, or the positive/nul/negative justification?
Thanks for your opinion, best regards, Michelot
