AECo (Automatic Electric Company) AUTOVON (Automatic Voice Network) Switch HEMP (High Altitude Electromagnetic Pulse) Performance Study.

摘要

The report comprises a description of the AECo AUTOVON switch,followed by a preliminary assessment of switch vulnerability to HEMP,in twenty critical circuits. The switch description covers the physical arrangement,the functional operations of the various subsystems in processing a call,the synchronization and timing of subsystem functions,and the automatic maintenance and diagnostic features of the switch. The vulnerability assessment takes into consideration the wiring,the interconnecting cable locations and lengths,and the component card circuits. The expected failure mode of each critical circuit is included. (Author)
