A lower bound on the reliability exponent of the memoryless exponential server timing channel with noiseless feedback is provided. The lower bound depends on whether fixed or random transmission time, as well as on whether fixed block-length or variable block-length, codes are considered (with block-length denoting the number of recorded departures). On the other hand we show that Arikan's one-way sphere-packing bound for fixed transmission time codes [3] applies as well to fixed transmission time codes for the case at hand. As for random transmission time variable block-length codes, a lower bound on the zero error capacity is obtained. © 2004 IEEE.
