Houses and standalone properties
We're responsible for the phone wiring up until your first telephone socket (usually this is the closest socket to where your phone cabling connects to your premises). This is called the Network Boundary Point (NBP). With some services (e.g. nbn®) this is at the Network Termination Device - a box that looks like a modem). Any internal wiring or sockets beyond the network boundary point are the responsibility of the owners of the premises.
You can contact us if you're unsure where your network boundary point is, or if a problem lies with your first socket / the wiring to the street and beyond.
Apartments, units and flats
If you're in a multi-dwelling premises (like an apartment, unit etc) , we're responsible for the wiring up until the network boundary point. The network boundary point for multi-dwelling premises is at the Main Distribution Frame (MDF). This is a box or cabinet where the telephone wiring for all of the premises on the property join together and connect to the wider network in the street. An MDF is normally found in a building's common area / garage and is normally locked. Any internal wiring or sockets beyond the MDF and into each dwelling are the responsibility of owner of the dwelling / premises.
If you live in a unit / apartment / flat: We recommend you contact an ACMA approved electrician to make your alterations as Optus generally can’t touch anything past the Main Distribution Frame (MDF). If you’re unsure of the location of the MDF, your Owners' Corporation / Body Corporate will be able to direct you to it.
If the problem lies with the wiring from the Main Distribution Frame to the street and beyond, contact us.
