Transmission errors modify the entangled state before the teleportation can be performed. We determine the changes in the output state caused by such transmission errors. It is shown that the errors caused by entanglement transmission are equivalent to the errors caused in a direct transmission of a quantum state from Alice to Bob.3 pages, contribution to the proceedings of the Quantum Information Technology conference QIT5 held November 12th to 13th 2000 near TokyoQuantum Physicstext
