I did research on Iridium in college and know that they DO have onboard
routing between satellite to satellite and satellite to ground station. I
do not remember seeing anything about them being able to do a source
quench. Iridium uses LEOs and is mostly digital phone traffic. (or
atleast it will be once in operation). My guess would be, that analog
satellites can only repeat the info in a normal bent pipe fashion. With
digital satellites, there is the possibility that they are active and could
route info, or atleast send a source quench.

Most current satellites are "bent pipe" repeaters - that is totally
passive. This is certainly the case for the Orion satellites, of which I
am most aware. Some of the newer LEO constellations have on- board
processing, but its not clear if any are router-like.
