We present a new entanglement assisted classical communication scheme which can correct a fixed number of erasures or errors. The scheme transmits classical information over a quantum channel assisted by maximally entangled pairs. We establish a general framework to accomplish such a task by reducing it to a classical problem. We use direct coding or super-dense coding based on the amount of entanglement available. This results in a combination of two classical channels. For this scenario we present an explicit encoding scheme. We compare our scheme with specific bounds and find certain ranges of parameters where the scheme is optimal. The presented scheme can easily be realized. It requires only the implementation of super-dense coding which has been demonstrated successfully in experiments.
