A block diagram is captioned "Figure 1. SRB Command Destruct System Functional 
Diagram".  Commands are received by command antennas and processed to the 
Integrated Receiver Decoder of Side B.  The signal is sent to the Side-B Distributor 
Subsystem.  Side A and B distributor subsystems have the capability for cross 
strapping.  The fire command is sent to the NASA Standard Detonators and passes 
through the Safe and Arm Device and the confined Detonating manifold. This in 
turn activates the destruct assembly, which contains the Linear Shaped Charge.
