Franklin Bell are ACMA certified cabling contractors. We specialise in the finding and removal and/or rewiring of splitters for NBN connections. 

If you have an internet service that's dropping out, disconnecting, or generally just problematic, chances are you need help with the proper setup of your cabling and central splitter. 

Splitters are not needed on NBN connections anymore, and unless they're removed, can cause connections to be unreliable and slow.

What Splitters Do

Splitters are electronic devices installed on phone cabling. Their primary purpose were to help ADSL modems work when these modems shared a line with any of the following devices:

  • Telephones
  • Fax Machines
  • Monitored Alarm Systems
  • EFTPOS Machines
  • Foxtel and/or Similar Devices Using a Land Line 

Why were splitters required on ADSL, and why do they need to be removed from NBN connections?

Splitters were required by ADSL connections in order to share the cabling from the phone exchange between internet modems and other devices. Now that Australia has moved to the NBN, these central splitters are causing problems with NBN connections, and need to be removed. The NBN does not share broadband and voice devices on the same line, and therefore splitters are no longer required.

Splitters were required because ADSL is a technology that makes use of older analogue phone lines to provide a digital connection for Internet, E-Mail and other modern services. ADSL modems need these digital signals to carry data. Other devices, however, don't understand these digital signals, and this causes problems. Splitters eliminate these problems by providing ADSL modems with the digital signals they need whilst removing the digital signals for devices that don't understand them.

Benefits of having ADSL central splitters removed from your NBN line

Back in the days of ADSL, central splitters helped ensure that your ADSL modem performs optimally. They're not needed for NBN connections anymore, and removal yields the following benefits:

  • Improved NBN Performance
  • Better Connection Stability
  • Fewer Drop-Outs and Internet Disconnections

Types of Splitters

Splitters are also called filters and they come in two varieties:

  • Central Splitters
  • Inline Splitters

Inline Splitters

Inline splitters are used where two or more device shares the same phone socket. They're efficient and cost-effective where devices are plugged into the same phone outlet and there are no other devices elsewhere (i.e. another room) on the same line. Inline filters are not the best solution where devices are located in different rooms or where alarm systems are present.

Inline splitters can easily be plugged back in, causing NBN drop-outs and other problems to reappear.

Central Splitters

Central splitters were usually the best option for ADSL performance when you had a monitored alarm system. Modern alarm systems are monitored in other ways, and don't require these splitters anymore.

How do I get a Central Splitter Removed from my NBN connection?

Central splitters need to be removed by ACMA certified cablers as they are hard-wired and their integration into your existing cabling needs to be considered carefully to ensure proper operation of all your telephony devices.

Quite simply by contacting us and booking in your central splitter removal, your NBN connection can be made faster and more stable.
