Generally when speaking of "phone line" it is in reference to
the physical transmission medium. Phone lines consist of
what is called a "twisted pair" of conductors. Cable may
incorporate the function of telephone communications, but
it uses coaxial cable (a mode of waveguide rather than a
conductor), where the signal is propagated through the
dielectric medium between the inner and outer conductors.
I think that DSL and ADSL are ways of multiplexing the
signal so that a greater bandwidth is achieved with a twisted
pair than was previously possible.
