Application
This unit applies to customer cabling terminated on sockets and network termination devices (NTD). It applies to the installation, maintenance and modification of indoor and external cabling.
Customer cabling, for the purpose of the ‘Restricted’ Cabling Provider Rule, may be used to connect devices for a range of applications, including telecommunications, simple data and computer use, security alarm panels and fire control panels.
Cabling may be metallic or optical fibre and may be aerial or underground.
The cabling task may be a new cable installation or upgrade of cable capacity for an existing network or subsystem for convergence to Next Generation Networks (NGN) applications.
The cabling installer may provide services in telephony, voice over internet protocol (VoIP), internet protocol TV (IPTV) and computer data over a single metallic customer cable or optical fibre cable in a specific customer location.
