In this work are obtained some criteria which guarantee the oscillatory behavior of the differential system of mixed type x′(t) = ∫0−1d[ν(θ)]x(t−r(θ)) + ∫0−1d[η(θ)]x(t+τ(θ)), where x(t) ∈ Rn, r(θ) and τ(θ) are real nonnegative continuous functions on [−1, 0], ν(θ) and η(θ) are real n-by-n matrix valued function of bounded variation on [−1, 0].
