Let {X (t): t is an element of R} be the integrated on-off process with regularly varying on-periods, and let {Y (t): t is an element of R} be a centered Levy process with regularly varying positive jumps (independent of X(.)). We study the exact asymptotics of P(sup(t >= 0){X(t) + Y(t) - ct} > u) as u -> infinity, with special attention to the case r = c, where r is the increase rate of the on-off process during the on-periods.
