Specifies the structure and requirements for pathways and spaces within or between buildings for information exchange and telecommunications cabling according to ISO/IEC 11801 and ISO/IEC 15018. Both single- and multi-tenant buildings are considered; safety aspects of the building design, fire stopping measures or

telecommunications systems that require any special types of security measures are not covered.

The telecommunications infrastructure is an integral part of building design. It may include

voice, data, environmental control, security, audio, television, sensing, alarms, paging and other low voltage and power limited signal systems. These systems are subject to frequent changes. Design of the pathways and spaces should accommodate this dynamic behaviour. This Standard significantly influences the design of other building services, such as electrical power and heating, ventilation and air conditioning (HVAC). Generally it makes no specific recommendations among the design options available for telecommunications pathways and spaces.
