MDF Jumper Connection A to B

If you have a new ADSL or Naked DSL service, your ISP may have advised you that you need to have an ACMA Registered Cabler install "A to B Jumpering" in your building's MDF.

What is an MDF?
MDF is the abbreviation for Main Distribution Frame. Essentially, it is the place in a Strata building or a commercial building where the copper Telstra telephone lines come in from the telephone exchange and are distributed throughout the building.

What is "A to B Jumpering" or an "MDF Jumper Connection"?
A to B jumper connection at the MDF is the interconnection of a Customer's line (from the MDF to their telephone socket in their apartment or commecial suite) to the ISP or Telstra's line from the telephone exchange.

What is involved in the MDF jumpering process?
1. The line from the exchange must be identified at the MDF with a "tag".
2. Your ISP advises you to contract a private ACMA Registered Cabler such as SE&D to make the connection
3. The SE&D technician tests the line from your telephone socket back to the MDF and identifies the line.
4. The SE&D technician interconnects the two sections of the telephone lines and records the details
5. The SE&D technician uses an ADSL test instrument to test your ADSL service for speed an quality.

SE&D is ACMA licensed, holding Master Cabler Licence T32494 and is fully endorsed to provide telephone and DSL cabling within your premises.

Our licensed ACMA registered cablers carry all the standard keys to access most MDF rooms in strata buildings, including NMB, TEL, MLV and ABLOY keys.
