Voice/Data Cabling

Definition

Voice and data cabling refers to the integrated copper cabling infrastructure that delivers both phone service and network connectivity to workstations throughout a commercial facility. In modern structured cabling systems, voice and data are both delivered over the same copper cable type (Cat6 or Cat6A), with the distinction handled at the network equipment level. In Voice over IP (VoIP) environments, telephone calls are transmitted as data packets over the same network cabling used for computers — eliminating the need for separate voice infrastructure.
