Digital Telephony Infrastructure
Cat3 is one of the leading innovators in Digital Telephony Infrastructure, transforming the old telephone system into world class digital networks.
Traditional telephone networks, using copper wire from telephone exchanges to consumers, have been largely ignored for the distribution of world-class digital communication. But in recent months, several new technologies have been combined to provide the same capacity as expensive new fibre networks using the existing copper wire infrastructure.
Cat3 has brought together the leading exponents of these breakthroughs to provide greater bandwidth over greater distance from exchanges more economically than any other operator.
Cat3 uses existing telephone infrastructure to deliver high bandwidth data
Many billions of dollars has been spent world-wide in laying expensive fibre networks “the last mile” into consumer premises. Now, Ironbridge can deliver one single high capacity fibre pipe into an existing telephone exchange and deliver whatever bandwidth is needed to every telephone connected to that exchange, no matter how distant.
Using a combination of ASDL, SDSL and its proprietary IDSL DSLAM technology, Ironbridge can deliver virtually any performance currently demanded over any distance from an exchange. This allows very high speed Internet access, distribution of exceptionally large data files as well as the
latest advances in Video-on-demand and Voice over IP.

Examples of performance achieved over an Cat3 network
Using existing telephone lines for carrying data does not affect the quality of telephone voice calls in any way. A complete renovation of a town’s data infrastructure can be achieved in a few days, with no digging of roads, no interruption of normal services and at a fraction of the cost of laying optical fibre.
The technology used has been installed in mission-critical military and medical installations as well as municipal and commercial installations around the world. Leading technology players are used to enable networks including Zhone, Paradyne and iGate for integration with IT and telephony systems from Microsoft, Cisco and BT.

Implementation is managed by Ironbridge and can be economically installed even into the smallest telephone exchange.

In the home or office, the existing telephone line is used to deliver both telephony and broadband connectivity, either to replace expensive leased lines or to provide high speed connection to the Internet.

Ironbridge partners with major players in the international data distribution marketplace, and is involved in competitive infrastructure bids on behalf of the world’s largest military organisations for the distribution of data across countries and across continents. Our understanding of the market and the
Optimisation of data transfer among and through competitive providers puts us in a unique position to deliver bandwidth to areas thought to be too costly or too distant.
Because Cat3 has no fixed allegiance to any one provider, or even type of provider, we can take an objective view of the methods used for getting data to end users economically. We can and do specify all of the proven and reliable methods of data transfer including the latest WiFi and even satellite technology where this proves to be the most appropriate in the specific circumstances.
Some frequently asked questions answered
Q. Is this new technology reliable?
A. It’s already been used extensively in Mission Critical applications and is sourced from world class providers
Q. How does it compare in price to fibre networks
A. We use existing fibre, satellite or WiFi to get as close to the end user as we can, delivering “The Last Mile” through the existing copper wire twisted pair telephone network. This has always been the most expensive part of any circuit and is where many thousands of dollars per consumer can be saved.
Q. What part does Ironbridge play in creating new networks?
A. Ironbridge manages whatever components of a new network the incumbent operator requires, from delivering bandwidth to a local location to installing and training consumers. Using trusted engineering partners like ERA Technology, Ironbridge can manage installation anywhere in the world.
Q. What compromises does using existing telephone infrastructure impose?
A. In order to get very high bandwidth over long distances, it is sometimes necessary to use multiple telephone lines or install additional equipment, but their costs are extremely small compared with the cost of installing fibre.
Q. What limits of bandwidth can be delivered over copper telephone wire?
A. The fastest bandwidths now demanded for internet Video-on-Demand and Voice over IP are well within the limits of Ironbridge equipped exchanges. Even Local Area Network Extensions can be carried over distance with little loss of speed.
