Custom router replacing Adtran SDX621i Community Fibre

Hello everyone, I've been looking out and about for ways to replace the crippled Adtran 621i modem with my Nokia XS-2426G-A XGS-PON Wifi 6 router but no success so far. I've got ssh access on both and managed to explore the files in both but I'm not sure what to change. On the Nokia router, I've already changed the MAC and Serial with 'ritool' and launching 'omciMgr' tells me that i've achieved O5 which means the fibre is fully initiated but no Internet LED. My hunch is that it may be a VLAN ID issue but tried already plethora of numbers (100, 101, 102, 911, 656, 987) but it could be an extra encryption layer too since the TTL monitor outputs a "key_mask exchange" too. 'adtn-omcid' command on Adtran doesn't tell me much either. I don't think there is a PPPoE layer on top.

So far, only the "HiSense LTF7267-BHA+" SFP module is the only one successfully connecting to Community fibre as discussed on this forum (https://www.ispreview.co.uk/talk/threads/ont-alternative-for-sfp-fans.39711/) but can't get my hands on one to research deeper.

AIUI the Adtran 621i is an ONT. Do you have a separate router?

Yes, the ONT connects to a separate router's WAN port. I want to replace those 2 with just a 1 does-it-all router.

This isn't easily possible. Some ISPs offer SFP modules in place of their ONTs, but I don't believe Community Fibre do this.

Most ONTs are wall mounted. Leave that in place and connect your new router to the ONT using Ethernet cabling ?

One of the joys of fibre is that you get a clean ethernet interface from the network. There is no excuse to give a customer a locked down router, [as opposed to a preset router] you can be entirely in charge of your own network and all you need to do is set up your router to provide PPPoE credentials to the ONT.

What you are proposing, OP, just blurs the ownership of the interface and will lead to ISPs wanting to lock down routers.

Unless its an alt-net whom are using one of those all-in one ONT & Router boxes, and the fibre comes straight from the wall into this box which is put on a table. Not good for fibre resilience, and probably more costly for the alt-net.

The op wants to from ont, which he thinks is "crippled" to a combined ont/router.

There is honestly little one can do with the settings on ont if you could see them except potentially mess your connection up and since pon is a shared network - others.

I have only once ever had an ISP which supplied a router - this was wireless - and I got the PPPoE credentials and then it was only kept for demonstrating that any fault wasn't mine. I would be highly resistant to an all in one ONT and router. The router belongs to the customer's network and is none of the ISP's business.

Dealing with a crippled ONT is one thing. A combined ONT router is just retrograde.

In what way(s) do you think the current device (an ONT, not a modem) is "crippled"? I doubt it's the source of whatever problem you're experiencing...

Won't work. The Nokia can't emulate an Adtran ONT.
