A method and system for multiline transmission in communications systems are described. The missiles are arranged inside the modules, which may be stacked in groups inside a single pressure vessel, or payload bay. Each data reproduction unit reproduces the stored test data into a reproduced test data set, which is then processed by a driver, and sent to the corresponding integrated circuit for testing. There is also disclosed a method for manufacturing such a wristband. The emitted high energy magnetic pulses are picked up remotely by a magnetic read head.
