Legacy Cable Systems and Their Impact on NBN

Traditional Cable Anatomy

Standard telephone cables consist of multiple pairs of insulated copper wires enclosed in a protective sheath. This sheath is commonly made of plastic insulation and covered with nylon. These are often known as 2-pair cables, designed to support two separate telephone lines.

The Prevalence of PSTN Wiring in Australia

In Australia, roughly 92% of homes come pre-wired for ADSL and POTS (Plain Old Telephone Service) via the PSTN (Public Switched Telephone Network). In these setups, extension wires often run parallel within a property using a technique referred to as “bus-wired” or “daisy-chain.” Standard cables usually feature:

  • “A” Wire (+ve): Typically white
  • “B” Wire (-ve): Usually blue
  • Additional Pair: Often red and black for a second phone line

The Limitations of Legacy Systems in the NBN Era

As Australia shifts to NBN services, these conventional copper-based, bus-wired systems have proven to be less effective in providing reliable internet connectivity.

The Flaws of Daisy-Chain Wiring

In traditional systems optimised for POTS and ADSL, daisy-chain wiring extends from the Network Interface Device (NID) or Main Distribution Frame (MDF) to each socket in sequence. While suitable for older systems, this arrangement poses challenges for modern NBN VDSL services. It can create “bridge taps,” which interfere with the VDSL signal and can result in decreased speeds and unstable service.

Star Wiring An Alternate Wiring Method

Star wiring, another method commonly used, links all extensions from a single central point. While this may have been effective for older systems, it’s worth noting that this setup can still introduce “bridge taps,” compromising the VDSL signal quality when transitioning to modern NBN services. Therefore, it’s not necessarily advantageous for maintaining a reliable NBN connection.

The Legacy-to-NBN Transition Challenge

Moving from traditional PSTN systems to advanced NBN VDSL services presents compatibility challenges due to outdated cabling in residences and businesses. While NBN promises high-speed, consistent internet, the old telephone wiring can introduce faults that degrade service quality. Join me as we explore these issues and their implications for NBN connections.

NBN Bridge Tap Issues:

Bridge taps, common in various NBN configurations such as FTTN (Fibre to the Node), FTTC (Fibre to the Curb), and now extending to FTTB (Fibre to the Building), are a primary source of signal disruptions. Stemming from older telecommunication structures, these offshoots deviate from the main line, leading to signal bounce-backs and weakening. As a result, you might notice a reduction in internet speed, erratic NBN service, or even a complete loss of connectivity.

High-frequency signals, essential for modern broadband service efficiency, are notably vulnerable to disruptions from bridge taps. Consequently, their identification and elimination are crucial in NBN fault repair. Specialised testing equipment is generally required to accurately locate these taps. When identified and removed by a qualified technician, immediate improvements in network quality are often observed.

What Your Cabling Should Look Like

Your home’s cabling system is the backbone for all your telecommunications services, including internet and phone lines. Traditional cabling systems, often configured in star or bus wiring (also known as daisy chain), are increasingly unable to meet the demands of modern internet usage. As an alternative, centralised cabling provides a more robust and efficient solution.

In a centralised cabling system, every outlet or access point in your home is directly connected to a Central Connection Point (CCP), usually situated near your modem or NBN device. Cables of Category 5 or higher are used to link to this hub, which supports both phone and data connections. A key component in this setup is the NBN’s lead-in cable, which links your external utility box to the CCP, forming the core channel for your NBN service and enhancing both its speed and reliability.

For this system to function optimally, a dedicated electrical outlet is required near the CCP to power your modem and any other related devices. If you depend on your phone for emergency services, it’s advisable to have a backup battery close to the CCP. This integrated, centralised approach minimises potential points of failure and makes the network easier to manage and troubleshoot. It also provides a sturdy, future-proof framework for all your digital communication needs.
