  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.
