Hello, friend!


By default, ONU ports support polarity reversal. You can run the display pstnport attribute command to check whether an ONU port supports polarity reversal.


Thanks!

Hello user! hope it can help:

All ONTs providing voice ports support polarity reversal impulse. To configure polarity reversal
impulse on an ONT, choose Voice > VoIP Advanced Configuration from the main menu on the web
page or configure the universal value-added service profile through the U2000.

Thanks!
