Previous version of my router appear to have a "modem mode" but that
doesn't exist in my version.
Here in Australia we have a national operator called NBN that runs its
own country-wide network and provides the Network Termination Devices to
every household and business.
Then we have a large number ISPs who connect to NBN and have a virtual
circuit established between them and each individual customer. It is up
to each ISP what services they provide. As a customer you are virtually
connected to an ISP router and have no exposure to the network inbetween
- which could be DSL or cable or fibre or even wireless.
What you see is what your ISP wants you to see. Some of them add an
extra box between you and the NTD to make it harder (allegedly easier
for them to manage it better, actually to lock you in).
You have the option of changing ISP to one that provides correct IP
services. That may include chucking out any extra box and connecting
direct to the NTD.
Here is something I found about the UK. OpenReach sounds very similar to NBN

Here's an overview of the broadband options and market structure in the UK:
1.
Openreach: Openreach, a subsidiary of BT Group, owns and operates
the majority of the UK's fixed-line infrastructure, including copper
lines, fiber-to-the-cabinet (FTTC) connections, and
fiber-to-the-premises (FTTP) connections. Openreach is regulated to
provide access to its infrastructure on a wholesale basis to other
ISPs. This means that multiple ISPs can offer services to consumers
using Openreach's infrastructure, with virtual circuits connecting
customers to their chosen ISP. Major ISPs, such as BT, TalkTalk,
Sky, and Plusnet, use this infrastructure.
2.
Virgin Media: Virgin Media is the largest cable broadband provider
in the UK, operating its own network separate from Openreach's
infrastructure. Virgin Media's network is based on Hybrid
Fibre-Coaxial (HFC) technology, which delivers high-speed internet
using a combination of fiber-optic and coaxial cables. Virgin Media
is not obligated to provide wholesale access to its network, meaning
customers can only access services directly from Virgin Media.
3.
Smaller ISPs and Alternative Networks: There are also smaller ISPs
and alternative network providers that offer broadband services,
including full-fiber networks, fixed wireless access (FWA), and
satellite broadband. Some of these providers, like CityFibre,
Hyperoptic, and Gigaclear, have built their own infrastructure in
certain areas, while others lease capacity from Openreach or other
network operators.
4.
Mobile Broadband: Major mobile network operators, such as EE,
Vodafone, O2, and Three, offer mobile broadband services using 4G
and 5G technologies. These services can be used as a primary
broadband connection, especially in rural areas where fixed-line
broadband speeds may be limited.
In summary, the UK broadband market is a mix of infrastructure providers
and ISPs, with Openreach's wholesale model playing a significant role in
ensuring competition among ISPs. Additionally, Virgin Media, smaller
ISPs, and mobile network operators provide alternatives to the Openreach
infrastructure.
