Fibre Broadband > Fibre Installation Process

This page describes some of the technical aspects involved in the customer connection process. While this information is provided for your education, the supplier and its Field Services Team handle everything involved in the infrastructure connection process.

In-premises wiring however is the responsibility of the end user and is explained in various sections throughout this page.

Build Drops

During the local street Fibre construction stage, NBN Tas Ltd. will invite end users to ‘opt in’ to what is called a Build Drop. A Build Drop is simply a Fibre drop cable connected from a Network Access Point (NAP) in the street to the nearest safe practical point on the premises but without an ONT being installed.

The end user Opt In to Build Drops campaign is being offered in Tasmania Stage 1 to:

  • Maximise the productivity of the construction effort whilst in each town.
  • Maximise the number or premises that are ‘NBN Ready’.
  • Most importantly with the help of end users, refine the methods and practices used to install drop cables to premises whether aerial or underground.

End users who have accepted the ‘opt in’ will be provided a drop cable for free compared to a potential higher installation charge if the ‘opt in’ offer is not accepted and they choose to order an NBN based service from the RSP of their choice.

The Optical Network Termination Device

The ONT installed usually on the outside of the premise and provides an easily accessible means of testing services. It is our Network Boundary and where our services terminate, so anything past the port(s) on the ONT is the responsibility of the homeowner and/or the retail service provider.

ONT Activation & Testing

Responsibility for the final activation and testing of the ONT resides with NBN Tas Ltd. and our Field Services Team. When we visit a premise to activate, test and then activate services to the ONT, the field contractor does the following:

  • Ensures the drop cable is correctly installed
  • Installs and makes the interconnection between the drop cable and the ONT
  • Installs the Power Supply Unit inside the premise and runs a 12v power cable to the ONT
  • Tests all connections in accordance with the relevant standards
  • Takes a light level Db reading then contacts the NOC to activate the relevant end user services
  • Completes all required documentation to ensure inventory databases are accurate.

In many circumstances TechLife – our field services team – may have independently organised with the end users during the ONT installation, to complete any required in-premise wiring. This is arranged directly between TechLife and the end user if the end user chooses to, giving them a better end user experience.

When we activate services at a premise, the Ethernet port is checked for connectivity to an internal web site and the telephone line is checked for side tone. This is done to ensure once the customer orders their services from the Retail Service Provider, you can be assured the services are working right up to the ONT.

Field Installation Install and Repairs Times

  • Demand Installs

Demand Installs will be undertaken from Monday to Fridays and appointments will be offered to end users by the Field Contractor between 8a.m. to 12 noon and 12 noon to 4 p.m. End users will be expected to be at their premises during the agreed appointment window.

  • Faults

Faults will be fixed from Monday to Fridays. The end user will need to provide consent for the field contractor to come onto their property in order to isolate the fault. Appointments will not be required unless the end user has an internal ONT or during the RSPs interaction with the end user, a problem is identified with the power supply unit. The fault contractor will determine whether the fault condition exists in the street distribution Fibre, the drop cable or the ONT. In-premise wiring is the responsibility of the end user. If an appointment is required, it will be offered as per Demand Installs.

Installation of ONT from the lead in cable

Once your order has been confirmed, our suppliers will then begin the process of ensuring Fibre is connected to you. Once confirmed the above diagram demonstrates the cabling the technicians will be provisioning. You will be contacted to organize a time for this cabling process as you must be at your premises.


Process of Activating Fibre Service


Installation of the ONT Optical Network Terminal

As the last step the technician will supply and install the Optical Terminal Network (ONT) to your premises. The next step (which is usually an option, Exetel is offering as standard) As part of the installation of the ONT, the technician will also install a Battery Back-Up Power Supply Unit –in the case of any power outages this will ensure the resident can still make and receive calls. It is the residents’ responsibility to provide an internal domestic AC 240V socket-outlet for the Power Supply Unit, as well as the battery. The battery must comply with the following specifications: 12V 7.0-7.2Ah Sealed Lead Acid Battery (6 Cells)


  • It is the responsibility of our supplier’s technician to install the Fibre service up until the (NBP) Network

Boundary Point. However, if the technician is unable to access the lead-in cable (blockage due to concrete/other materials).

  • Then the order may be on hold and further charges may be applicable if additional work is required to access.
  • The conduit to complete installation of the Fibre service.
