A true modem doesn't have an on-board CPU.
Not even 56k modems using frequency, amplitude, and phase shifting.
There are hybrid digital/analog ICs (integrated circuits) which dothis right from the factory, needing only connectivity to power,
a few external discreet elements (resistors, capacitors and/or
crystals.

Some are flasheable, like mine. That usually implies a flash memory and cpu of some kind, even if part of a dedicated chip.
