With a FTTH connection we have a BT Openreach provided ONT where the GPON fiber connects.
In the past I've asked if this ONT could be replaced, but it seems it could not.
Recently though, a few products have come on the market which may change this. From Mikrotik and Ubnt. The UBNT UFibre Nano G seems to have been made to work on many other FTTH infrastructures. The reason it can do this is it seems GPON "security" works based on the serial number of the device being used. The NanoG can have its serial number changed by script. (See UBNT forums).
My question therefore is: Do BT use the standard GPON ONT Serial Number as the only security method to allow the ONT to sync with the Exchange OLT?
If I change my NanoG's serial number to match the Openreach Huawei ONT's one would it work?
I know about the ISP PPPOE connection that is layered on top, but not interested in that at this stage.
Thanks in advance.
