Piecewise homogeneous Poisson process

Is there a name for a Poisson process which is piecewise homogeneous? I.e. time-homogeneous but with a parameter change each increment. Any references appreciated.

The sequence of events corresponding to a sequence of independent, not necessarily identically distributed, interarrival times is called a generalized renewal sequence or a general renewal process. Thus, the random process you are interested in is the counting process of a general renewal process.

Inhomogeneous Poisson processes are different beasts, described by some, nonconstant but deterministic, intensity function $\lambda:t\mapsto\lambda(t)$.
