In reality, these are protocol stacks such as IP over PPP over ATM over
DSL, but it makes the ASCII artwork very confusing.

Let me counter with:

ROUTER - ip/ethernet - DSLAM - ip/ethernet/atm/dsl - CPE - ip/ethernet - COMPUTER

In some cases a modern dslam will do routing as well. ATM was close to death before DSL came along, please don't CPR it anymore. Let it R.I.P.
