This document is an information security manual that outlines guidelines for communications infrastructure, specifically applicable to facilities located within Australia. It details the requirements for cabling infrastructure, including the use of fibre optic and copper cables, and emphasizes compliance with relevant Australian Standards. The manual describes the importance of maintaining a cable register to assist in tracing cables and preventing unauthorized changes. It also covers the development of floor plan diagrams that aid in the accurate location of cabling components. Additionally, it discusses the significance of cable labeling processes to minimize errors in cable identification and to facilitate fault finding. The document specifies the standards for cable colors to differentiate between various classifications, such as SECRET and TOP SECRET systems. Furthermore, it addresses the need for inspectability of cabling infrastructure to detect tampering or degradation, and outlines controls for managing cable bundles and conduits in shared facilities.
