We have demonstrated real-time decoding of 20-bit biphase-coded address header pulses, using stimulated photon echoes in a phase-matched crossed-beam configuration. This decoding is one of the functions required for coherent transient optical data routing, packet switching, and processing. The active medium used was single-crystal Y<sub>2</sub>SiO<sub>5</sub> doped with Er<sup>3+</sup>, which provides an operating wavelength of 1536 nm.
