الشرح
A linear transponder shares a fixed output power budget among all signals passing through it, and its automatic gain control responds to the strongest one, so an excessively strong uplink takes the transponder's power and pushes everyone else's downlink signal down. It does not overload batteries or reboot the spacecraft; those are command functions, not transponder functions.
