R56: Protecting Your Communication Center Console Furniture


Developed and maintained by Motorola Solutions in 1987, the R56 guidelines were first drafted as an internal reference document. In 1994, however, the R56 guidelines were modernized, published, and have since been regarded as the guiding standard for safety protocols in the communications industry. The R56 guidelines are a broadly accepted trade standard that outlines the requirements and regulations pertaining to the installation of communications infrastructure and facilities. R56 standards have been widely adopted by our customers and even our competitors for all installations of console units. Overall, the R56 standards and guidelines have driven stringent surge protection requirements necessary for high-reliability communications networks.
