But your router isn't where the Telco's responsibility ends. It ends
back at the card with the blinky-lights on it, usually mounted next
to the protector block at your MPOE.
It's the DS0/T1 equivalent of the ONT.
(They can also send test signals to it as well.)

An interesting claim given that the Telco twisted pair you are holding up
as a shining example did involve electronics, splitters (known as bridge
taps) etc.
