This is a coms room that has been very neglected, we were asked to change over the old LG ARIA phone system to a newer LG IPECS system Mission complete but the system tails and the mdf Jumpering needed to be re directed to the newer location What is MDF Jumpering? MDF jumpering is a connection between a carrier network (Telstra, Optus, NBN, iiNet, Internode, Belong) and your telephone equipment (phone system, ADSL, phone or wall socket). Your phone/ADSL service provider mainly uses NBN or Telstra’s infrastructure and their technicians will generally connect your line to the MDF and “TAG” with your line ID and apartment number or name , from there it is your responsibility to complete the installation to device or phone jack in your home, apartment or office.
