MDF Jumpering

Our licensed and registered technicians can perform MDF jumpering for your apartment, townhouse or business premises to connect your new phone line, NBN or ADSL service.

When you first move into an apartment, townhouse or business premises you may not have a dial tone or have internet access, this can be because the main lines in the MDF room need to be routed via MDF jumpering cables to get the signal to your socket. In these situations, your service provider will tell you to contact a private telephone technician like us to complete the jumpering.

Our MDF jumpering service is performed by fully licensed and qualified telephone technicians to connect your new phone line, NBN or ADSL service.

What is MDF Jumpering?

When you sign up for a new telephone or internet connection, your service provider needs to connect the wiring from the telephone exchange to the Main Distribution Frame (MDF) in your apartment, townhouse or business. MDF Jumpering is the physical connection between your internal phone network and the service providers network via a cable called a jumper wire.

The MDF is divided between an A side and a B side and the jumper will connect the two together. Your service provider will connect the A side and tag the line so that our technician can then connect it to your line on the B side.

Before Your Appointment

Before giving us a call, make sure your service provider has been out to visit you first. They need to tag the phone number allocated to you in the MDF room so that we can complete the jumpering connection. After your service provider has connected to the A side of the MDF, our technician will connect it to your line on the B side of the MDF.

To ensure we can connect you smoothly, you may also need to contact your strata or building manager to confirm the location of your MDF room and to organise access for our technician. We have master keys for most common MDF room locks, but it’s best to check this in advance as sometimes there is a special lock and key installed. You can also take a photo of the lock on the door and send it to us for confirmation.

On the Day of Your Appointment

When your technician arrives, they will use a tool to trace your phone line through the phone socket back to the MDF room. They will then complete the jumpering connection in the MDF room. It’s important to ensure your service provider has already visited and tagged your line correctly – every property has its own line and only the service provider knows which belongs to who. If this isn’t the case, our technician will still perform as much of the jumpering as they can and then the service provider will have to finalise their part.

Don’t worry if this sounds complicated, our friendly technicians are very familiar with the process and will guide you the entire way. Please feel free to get in contact with us for advice or if you have any questions.
