The far-infrared (FIR) c axis conductivity of a Bi2223 crystal has beenmeasured by ellipsometry. Below T$_c$ a strong absorption band develops near500 cm $^{-1}$, corresponding to a transverse Josephson-plasmon. The relatedincrease in FIR spectral weight leads to a giant violation of theFerrell-Glover-Tinkham sum-rule. The gain in c axis kinetic energy accounts fora sizeable part of the condensation energy. We also observe phonon anomalieswhich suggest that the Josephson-currents lead to a drastic variation of thelocal electric field within the block of closely spaced CuO$_2$ planes.Comment: 8 pages, 3 figure
