The main purpose of the present paper is to give some properties of the Jacobson radical,the Frattini subsystem and c-ideals of a Lie triple system.Some further results concerning the Frattini subsystems of nilpotent and solvable Lie triple systems are obtained.Moreover,we develop initially c-ideals for a Lie triple system and make use of them to give some characterizations of a solvable Lie triple system.
