A MDF is the Main Distribution Frame from where the Telstra main cable from the exchange is terminated in your property. Telstra is responsible for any connections or repairs to the end of their cable at the MDF and are also responsible from the MDF to the telephone exchange in your local area. When you live in a unit block or a business premises and have a new phone line installed, your Telco provider E.G Telstra, TPG, Optus, etc, will connect your line to the exchange side of the MDF, this is where there responsibility ends. Your MDF has two parts to it, the exchange side where the Telstra main cable terminates and the occupant’s side where the cables from your unit or office will terminate.


When you have a new line connected a contractor from your Telco will visit your premises and connect the line to the exchange side of the MDF, but a Jumper wire will need to be run to connect the two sides of the MDF together so your phone and internet can work at your phone socket. Usually the contractor will tag the exchange side of the MDF, this should mean that the contractor has installed and tested the line to that point. If you are not home when the connection is made you may receive a card in your letterbox stating that your phone line is now ready, but if you plug your phone into the socket and you still have no dial tone, this could very well mean you need a jumper wire is required at your MDF.
