Communication defines our everyday life, informs us, imparts knowledge and experience. It supports our understanding and helps us solving problems. WISI‘s highly-motivated staff is fully committed to provide you with the state-of-the-art technology for communication today and tomorrow. Powerful technology, compact dimensions, modular and flexibly expandable; the new WISI COMPACT HEADEND System OH combines all the advantages of an innovative and affordable headend. WISI Compact Headend OH is easily tailored with up to 14 modules and thus offers optimum channel processing for up to 14* analogue and 28 digital channels in a 3 HU 19“ rack chassis. WISI Compact Headend OH operates on a high efficiency power supply, with low consumption modules in order to make a minimum ecological impact and a low operational cost. The USB connection and the RJ45 bushing can be used to execute software updates for the basic unit as well as for the modules. Furthermore, all functions can be furnished from a distance per web browser.
