There really aren't that many modem/router combos out there you can actually flash with open source firmware.
Router? Sure, no problem.
Modem? Outside of some very niche Fritzbox devices and others listed on OpenWRT Table of Hardware
There really just aren't that many.
So, fine. I will use a proprietary modem.
I will put it into bridge mode, let it decode the DSL analog signals into ethernet and feed that into a router of my choice.
Question is: Which modem?
I don't want two devices heating up my shelf. I just want a tiny modem that converts analog to digital into an RJ45 and then let's the router do its thing.
Does such a magical device exist, because my search on this front has proved largely fruitless
That's a chunky house warmer, let alone shelf warmer!
I can understand that ISP's need to protect their security (through obscurity) so that no one's going around cloning their neighbors analog signals to score free internet... but surely the actual hardware to do the tone pairing / channel matching analog-to-digital-magic-mumbo-jumbo does not need to be the size of a brick?
In the spirit of people cutting open Nintendo Wii's shearing down the chip and making compact versions[0], has no one isolated the hardware on a modem, chucked out the routing stuff, and compacted the whole device to be no bigger than a USB stick?

The fibre modem my ISP uses is pretty small, about the same size as one of those small unifi switches, but it still feels like there's almost nothing in it.
I have taken apart the fibre modem of a different provider before, which was just a small PCB no larger than a raspberry pi and a fibre extension cable.
It was packed in this hunk of junk.

Hmm! Good to know there's some hope with the size of fibre modems
