Franklin Bell are ACMA certified cabling contractors. We specialise in the installation, repair and alteration of splitters, ADSL lines and their related components.

If you have an ADSL 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. 

What Splitters Do

Splitters are electronic devices installed on phone cabling. Their primary purpose is to help ADSL modems work when these modems share 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 are splitters required?

Splitters are 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 a Central Splitter

Central splitters help ensure that your cabling performs optimally. With a central splitter in place, you can expect to see the following:

  • Improved ADSL Performance
  • Better Connection Stability
  • Less Noise on Phone Conversations
  • Fewer Drop-Outs and Internet Disconnections
  • Less Problems with EFTPOS machines, faxes and monitored alarms

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 unplugged and/or removed, causing ADSL drop-outs and other problems to reappear. Other difficulties with central splitters include the fact that they need to connected in a very specific way - any other way and they don't work at all.

Central Splitters

Central splitters are the best option when you have a monitored alarm system. They're also great when there are more than 2 devices that share the same phone line and they're not plugged into the same physical phone socket. For example, if you have and ADSL modem in one room, a phone in another and other devices such as a fax, Foxtel or EFTPOS system somewhere else, a central splitter is the most reliable and efficient way to ensure these devices can co-exist on the same line without problems.

Central splitters cannot be accidentally unplugged or removed as they're hard-wired into the phone cabling by a suitably qualified technician. Central splitters are usually placed out of sight and out of mind, where they do their job behind the scenes and you'll probably forget it's even there.

How do I get a Central Splitter?

Central splitters need to be installed 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.
