DSL coax modem? (Frontier) (alien.top)

Hi, all. Trying to sort options and hoping to rule this in/out.

Frontier DSL, installed 10 years ago as AT&T Uverse (Voice/Internet/TV then; dropped voice/TV a few years ago) with a Pace 3801HGV gateway. Phone jack was in a bedroom. Installing tech replaced that with a new wall jack that has phone/data ports and a coax jack. Coax runs out of that wall jack to another coax wall jack across the room. Then in the living room, coax runs from another jack there to the gateway. So, outside the wall, it's all coax.

Frontier wants me to replace the Pace. They have sent me two Arris NVG443B which do not have any coax input. Connecting the Arrises via the modem's DSL port to the data port on that bedroom wall jack has not produced working internet through numerous online/phone chats. They insist there is no current option for a modem that will connect via coax, and they need to send tech to get one of the Arrises working.

Short question, I guess, is, is that correct? Are there really no up to date versions of that Pace gateway or its like that I can just plug and play via coax? Or has this ship sailed and I'm going to need tech help? Much thanks in advance.

I’m not really familiar with ADSL and how it works but I am well versed in RF including DOCSIS (cable).

The balun (stands for balanced to unbalanced) is to change from twisted pair to the 75 ohm coax used by your modem. It seems like an extra step - they should have run a jumper rather than go through the unnecessary conversion to coax.
