MIL-D-81950, MILITARY SPECIFICATION DESIGN AND EVALUATION OF SIGNAL TRANSMISSION SUBSYSTEMS, GENERAL SPECIFICATION FOR (24 SEP 1974)., This specification covers the general requirements for design and establishes uniform methods for testing signal transmission subsystems. For purposes of this specification, a signal transmission subsystem (STS) includes the energy source(s) and output control function devices, and is composed of the following components: cartridges, electric initiators, cartridge actuated devices (CAD's), transmission lines, and other associated equipment (see 6.3.2). The transmission lines (hose/tubing, detonating cord, electrical,deflagrating cord, optical, etc.) provide the means for routing a signal(s) between STS components.
