The periodic version of Kondo's s-d exchange model is studied within the local approximation with NCA techniques. We present results for the local T-matrix and the local conduction-band density of states (DOS) in the different physical regimes of the model. We find an insulating gap for antiferromagnetic exchange in the particle-hole symmetric model, while off particle-hole symmetry the system appears to be metallic. For ferromagnetic interaction no apparent changes compared with the non-interacting case are found. For antiferromagnetic exchange coupling we compare our results with the behaviour typically found in heavy-fermion systems.
