Hello,
I have two Huawei HG8145V5 ONT routers, both bought from OLX. Each device has a unique serial number on the backplate, as well available in the ONT authentication menu as shown below. I copied the serial from my working ONT (registered with Airtel), and copied it to the backup ONT. The backup ONT was able to authenticate with the upstream OLT and I was able to get internet.
At some point i want to get rid of the ONT altogether and replace it with a transceiver like so which has been discussed before. This is just one piece of the puzzle.
Also, I noticed that the Huawei router only use the last 8 characters of the serial number and prepends it with HWTC to make up a 12 character string. The Nokia router G-140W-F does not provide the UI for changing the serial number, but uses a similar format and the string is ALCL.
By the way the initial digits of serial number on the HUAWEI ONTs, HG8145V5 and EG8145V5 device is 48575443. These is the hexadecimal for H (0x48) W (0x57) T (0x54) C (0x43). Likewise Nokia router ALCL will have 41 4c 43 4c.
