As part of its Electromagnetic Pulse (EMP) Mitigation Program, the National Communications System (NCS) funded ATandT to study the ability of the ATandT 5ESS(TM) Switch to withstand the potentially disabling effects of EMP from high-altitude nuclear bursts and fallout radiation from distant near-surface bursts. This volume reports the results of the assessment of the survivability and performance of a standard 5ESS Switch in a HEMP environment. A fully operational 5ESS Switch and its ancillary central-office support equipment were exposed to simulated-HEMP fields of 5 kV/m to 80 kV/m at the Air Force Weapons Laboratory test facilities. The tests (1) established the physical survivability of the switch, (2) investigated the types of upsets that occur (i.e., temporary and permanent changes in logic-circuit functioning), and (3) characterized the performance of the switch upon exposure to one or more EMP pulses as a function of incident field level and time after exposure. Performance was characterized in terms of the switch's ability to (1) hold calls set up before the EMP exposure, (2) recover automatically from EMP-induced upsets, and (3) establish new connections during and after recovery.
