Numerical modelling is performed for extreme relativistic parallel shocks with upstream Lorentz factor \Gamma = 50 . Assuming the scattering is either large angle or over pitch angles \sim \Gamma ^ { -1 } , spectral flattening and shock aaceleration speed-up is found . The energy gain for the first shock cycle is \sim \Gamma ^ { 2 } . The likely output from relativistic shocks due to the infall from the accretion disk to the AGN black hole is computed . Neutrinos from proton-gamma interactions may be detectable with planned neutrino telescopes .
