Admittedly, this review is from a somewhat biased perspective, as I am the author. Bill Flanagan, my Technical Editor, is a big part of the reason for the long gestation period. Bill h Admittedly, this review is from a somewhat biased perspective, as I am the author. Bill has an extensive background in telecom and, as a formally trained mathematician and physicist, possesses a different perspective on the subject.

Moreover, Intelligent Networks and Advanced Intelligent Networks have surpassed the wildest expectations of the service provider. These logical extensions of the network bear higher revenue while opening the network up to a myriad of new services.

Number portability can also be categorized into the logical elements because the number switching and logic are no longer bound to a specific system. A physical element is the actual switching element, such as the link or the matrices used internally. A network is made up of a unique sequence of logical elements implemented by physical elements. Given the local exchange network and local transport markets, open mandates had to be considered because the LEC has the power to stall competition.

In many documented cases the LECs have purposefully dragged their feet to stall the competition and to discredit the new provider in the eyes of the customer. This is a matter of survival of the fittest.

Transmission and Network Architecture

This is the basis for the deregulatory efforts in the networks, because the LECs are fighting to survive the onslaught of new providers who are in the cream-skimming mode. If access mandates are necessary, to what degree? These and other issues are driving the technological innovation, competition at the local loop, and the development of higher capacity services in a very competitive manner.

The Local Loop So much attention has been parlayed on the local loop. Nevertheless, is it a realistic expectation to use the network facilities for future high-speed services? These issues are the foundation of the network of the new millennium. Therefore, the field of competitors will continue to metamorphose as the demand dictates and as the revenues continue to attract new business.

The Movement Toward Fiber Optic Networks A transmission link transports information from one location to another in a usable and understandable format. The three functional attributes of this link are 1. Capacity 2. Condition 3.

The current copper-based loop limits opportunities. As broadband services become increasingly popular, the copper network severely constrains the broadband services. This precludes a lot of the innovation desired by the end user. Although the current copper-based network is unattractive to unbundle the physical transmission components, fiber-based networks offer many more opportunities.

The local access network can be improved by telephone companies by deploying fiber in the future. The central office, nodes at remote sites and the curbside pedestal can all be improved with fiber-based architectures.

These nodes serve as flexibility points where signals can be switched or multiplexed to the appropriate destination.

A small percentage of lines are served by digital loop carrier DLC systems that incorporate a second flexibility point into the architecture at the remote node. The third flexibility point at the pedestal has been proposed for fiber-to-the-curb systems in the future.

The bandwidth limitations of a fiber system are not due to the intrinsic properties of the fiber, but the limitations of the switching, multiplexing, and transmission equipment connected to the fiber. This produces many attractive alternatives to the broadband networks for the future.

No longer will bandwidth be the constraining factor; the application or the computer will be the bottleneck. Because of the tremendous bandwidth available with fiber optic cable and the technological improvements in SONET and Dense Wave Division Multiplexing, virtually unlimited bandwidth will be available.

Yet, installation of new technology is a slow process.

Fiber will be deployed in hybrid network architectures, which continue to utilize existing portions of the copper network. Consequently, until fiber is deployed all the way to the customer premises, portions of the network will continue to present the same speed and throughput limitations.

Digital Transfer Systems The switching and multiplexing techniques characteristic of the transmission systems within the network are all digital. Currently, the network employs a synchronous transfer mode STM technique for switching and multiplexing these digital signals. As a result, wherever SONET equipment is used, the standard interfaces at the central office, remote nodes, or subscriber premises will be multiples of these rates. Above the physical layer, however, changes are now underway that move away from the synchronous communications modes.

The asynchronous transfer mode ATM is the preferred method of transporting at the data link layer. ATM uses the best of packet switching and routing techniques to carry information signals, regardless of the desired bandwidth, over one high-speed switching fabric.

If natural monopolies are still in the local exchange network, open access to these network resources must be fostered to promote a competitive market in spite of the monopolistic nature of the ILECs. The FCC continues to wrestle with how far it has to go and what requirements are necessary to open and equal access to the network. Network unbundling, the process of breaking the network into separate functional elements, opens the local access to competition.

CLECs select unbundled components they need to provide their own service. If the unbundled price is still too expensive, the service provider will provide its own private resources.

This is the facilities-based provider. All too often, we hear about new suppliers who offer high-speed services, better than the incumbent.

The only change that occurs is the person to whom we send the bill. Hardly a competitive local networking strategy. Components of the Telecommunications Networks Telecommunications network components fall into logical or physical elements.

Switching systems have evolved into the use of external signaling systems to set up and tear down the call. These external physical and logical components formulate the basis of a network element.

Moreover, Intelligent Networks and Advanced Intelligent Networks have surpassed the wildest expectations of the service provider. These logical extensions of the network bear higher revenue while opening the network up to a myriad of new services.
