This task group focuses on the physical security of the telecommunications infrastructure as specified under the TIA TR-42 Telecommunications Cabling Systems Committee. The group specifies physical network security requirements, guidelines for the telecommunications infrastructure in customer owned premises, and compiles information that may be used for the design of physical network security system products. This work enables the planning and installation of physical network security systems that protect critical telecommunications infrastructure elements from theft, vandalism, intrusions, and unauthorized modifications, as well as establish minimum functional performance of different physical network security elements.
