What is MDF Jumpering?

 

MDF jumpering is required when a new NBN service has been tagged at the MDF in an apartment complex or office block by Telstra/NBN. Telstra/NBN owns the copper and fibre network and connects new NBN service from the ISP (Internet Service Provider) DSLAM in the Exchange to the customers MDF.

Sometimes the line will work if connected properly to the right pair on the A side. If not, you need the MDF Jumpering from A side to B side. That’s when MDFMAN is required to jumper this to a socket within the apartment. Also sometimes you may have a problem with the internal wiring from your unit to the MDF. This can be fixed by the MDFMAN.
