Abstract:

The content of this report is defined by paragraph 31 of the Statement of Work for contract DCA100-88-C-0027. This report documents Task 1 and 2, Test-Bed Design, Installation, and Baselining of the 4 ESS Switch Electromagnetic Pulse EMP Assessment Program. ATT has engineered an operational digital 4 ESS switch for the purpose of testing the susceptibility of 4 ESS switch systems to high-altitude EMP. The switch is installed in two specially designed trailers that are transparent to electro-magnetic radiation and is located in Colorado Springs, Colorado, where current-injection testing and further performance baselining is presently underway. Batteries, air conditioning, and spare parts are housed in two additional trailers. ATT Bell Laboratories has developed and implemented a test system for generating current pulses, monitoring the pulses, generating calls, and measuring switch performance. Digital traffic has been successfully generated and switched for three signaling systems Multifrequency MF Common Channel Signaling System 7 CCS7 and Q.931 used on direct Integrated Services Digital Network connections. Due to problems in acquiring properly engineered signaling- translation software, however, the CCS7 and Q.931 signaling systems have not yet been implemented with a full complement of trunk assignments. Subsequent tasks will entail further baselining, provisioning of backup methods for the operating software, and current-injection testing of the switch.
