Get PON Serial Number ZTE

Hello everyone, currently I am trying to retrieve the value of the ZTE ONT serial number, but the one I am currently obtaining does not match what I desire. Is there any additional information on how to obtain the PON serial number as shown in the image? Currently, the value being retrieved is 5C3A3D-F609-ZTEL. Thank you for your assistance.

Refresh the entire datamodel for the ONT in question. Then open the ONT in the GenieACS UI and search for the value you desire. Its possible the value you seek is exposed via a custom parameter.

Thank you for your suggestion, I will give it a try.
