Currently, the only possible GPON parameters to configure in XX530v v1 are the following:

But this greatly reduces compatibility with different providers, given this product IS AVAILABLE for retail in some countries, and people can buy it to replace ISP ONU/ONT, because it's a great router.

The problem is many internet providers validate more information that what is possible to configure in XX530v (V1), therefore my proposal is:

Allow a broader range of GPON parameters to be configured (AKA "OMCI information")

Like this:

For example, if a certain OLT need a specific value for SOFTWARE VERSION 1 that is different than what XX530v normally sends, this device could work with that OLT if that value could be configured (instead of being HARD CODED).

GPON SN is a example of this: the device has its own GPON SN printed below it, but it's possible to change it in order to allow it to be registered to the OLT.

We only need more parameters to be configured, like

Vendor ID

SOFTWARE VERSION 1

software version 2

OMCC version

Product Class

HW version

OUI

Device Serial Number

MAC

It would improve compatibility a lot, and make it competitive with other ONUs/ONTs.
