Australian IT & Telecommunications Infrastructure

Synopsis

Telecommunications 101

By 1965 The Public Switched Telephone Network (PSTN) connectivity model was obsolete; and had been replaced by three fundamentally different network structures: Customer Premises Network (CPN), Customer Access Network (CAN), and Inter-Exchange Network (IEN), otherwise knows as the Backhaul Network or Core Network. With these Demarcation Points clearly defined for a wide range of Technologies; common sense network interconnect can now prevail. 

 

Converging Network Technologies

Network transmission technologies have gradually morphed with timeAccess Networks are again utilising the transmission technologies used in the Inter-Exchange Network (now better known as the Backhaul Network or sometimes the Core Network). 

 

Steering the Australian 
Telecommunications & IT Future

To date (2004) international corporate greed was the prime business driver to 'restructure' the Australian Telecommunications sector.  This brief analysis provides a rational alternative strategy that will support all stakeholders and keeps this infrastructure in Australian hands.

 

The Customer 
Access Network (CAN) 

Originally all the CAN was on Poles, but this document on the CAN structure steps through the CAN development .  There were step improvements to "condition" the physical line to extend the useful length and performance.  Much of the CAN is Digital and Hybrid Fibre Coax (HFC) for Cable Television and Internet. There is also Hybrid Fibre/Coax  Radio for Personal Device and Outback Connectivity.  Most of these CAN constructions are moving towards Fibre to the Premises as the CAN of the Now

 

 Non-Urban Inexpensive Fibre to the Premises 

(Inexpensive Non-Urban FTTP)

With the CAN and BN converging technologies in both using Single Mode Optical Fibre (SMOF) Cables, there is a massive productivity gain that could be realised in Australia by deliberately using "thicker" BN cables and deliberately sharing the spare fibres for Homestead connectivity.  This short document shows how easy and inexpensive Non-Urban FTTP could be! 

 

 Inexpensive Metropolitan Broadband Infrastructure

In Metropolitan areas, by about 2 km of pair-copper cable, the ADSLxx Download speed has already plummeted from the nominal 24 Mb/s to about 16 Mb/s.  The average Metropolitan pair-copper length is about 3 km, so many ADSLxx services have Download speeds of about 4 Mb/s.  As HFC Internet is already installed and decentralised to virtually every Metropolitan Local Exchange, if all ADSLxx services over say 2 km distance from the Local Exchanges were replaced with the already existing HFC Broadband Internet facilities, then all the Metropolitan area (about 6,000,000 premises) would be inexpensively connected with Fast Broadband Internet and could  have Download speeds well exceeding 16 Mb/s.  

 

The Backhaul Network (BN)

In Telecommunications, the Inter-Exchange Network or Backhaul Network are synonymous with what some in the IT fraternity call the Core Network. This brief set of tutorials covers:  What the Backhaul Network is, what a Typical National Inland Structure would look like, an historical view of the Backhaul Network Transmission Systems, an historical view of the Backhaul Network Switching Systems,  an overview on Synchronising the newer Digital Backhaul Transmission Systems and Digital switches, the rebuilding process from Analogue to Digital to IP connectivity, and an overview of the Internet Protocol Backhaul Network structures. 

 

The Six Network 
Topologies

Most people in the IT and Telecomms businesses have a very myopic network vision and see only one IT or Telecomms network! There are six very different geographical  network topologies that seamlessly join to make end-to-end connectivity. In synergy, these six network structures form a very efficient Telecommunications / IT infrastructures.  

 

Maximising Telstra's Value 
for all Australians

This is so obvious that it hurts me!  The life-blood for Australia's ongoing wealth is an operationally efficient and cost-effective Australian telecommunications infrastructure.  Competitive businesses are on course to totally asset-strip (privatise) this infrastructure making it both more costly for end-users and very inefficient to operate. Here is the background strategy dated from about 1990 to stop asset stripping the Australian Telecomms Infrastructure.
