INTRODUCTION

The Internet is the fastest growing communications technology in history, far outpacing the adoption rates seen for the telephone, or even television. Today it already represents a major publishing outlet for news, information and many forms of entertainment. In the future it will reach millions of home users as well as businesses and it will continue to influence and profoundly impact not only the lives and lifestyles of an unprecedented number of people but also the paradigms used for doing local as well as global business. Therefore it is crucial that the Internet access and services markets develop in ways that are most beneficial to the consuming public. Consumers are best served when prices are affordable and competitive, and when there are a variety of quality products and/or services from which to choose that are readily available. Currently the market for providing broadband access technology, which is the next generation of Internet access technology, is developing quickly, and is wildly dynamic in terms of mergers and legal activities. However, it is unclear if the industry's current structure and competitive forces will provide and serve the public in the most beneficial manner as described above.

Currently, there are two primary methods competing to provide broadband Internet access to the home Digital Subscriber Line (DSL) technology, offered by the telecommunications industry, and the Internet-over-cable technology, offered by the cable television industry. However, currently the two industries operate under very different conditions due to the Telecommunication Act of 1996, which forced local telecom monopolies to open their infrastructures to competition but, to date, gave no such directive to the cable industry. However, that does not mean the cable industry will not be further scrutinized in the near future to determine whether or not the Telecommunications Act applies to it as well. In fact, the cable industry today very much resembles the telecom industry in the days leading up to the Telecom Act. Like the local telcos pre 1996, today's local cable operators enjoy regional monopolies and control infrastructure over the last mile of cable into homes and businesses. Also like the pre-Act telcos, the cable companies are facing pressures from consumer groups and potential competitors, especially Internet Service Providers, such as AOL, to provide access to their cable infrastructure. The concern is that the local cable monopolies, if not forced to open up, will control all aspects of last mile Internet cable access to the home in the near future. Of course, these potential competitors, who are currently locked out of the cable access industry, would gain substantially if the cable companies were forced to allow them access to their cable network. The question is whether the public would also gain.

In 1996, Congress passed the Telecommunications Act to resolve many of these issues for the telecom industry. Should Congress mandate something similar for the cable industry? To decide which course of action should be taken with the cable industry, one should consider the impact the Telecommunications Act had on the telecom industry since there is a remarkable parallelism between the pre-Act telecom industry of yesterday and the cable industry of today.

Consequently we will begin our study with an analysis of the telecommunications industry and the Telecommunications Act of 1996. We will then examine the cable industry, its similarities to the telecom industry, and the current dynamics that will influence the future decisions.

 

 

TELELPHONE INDUSTRY HISTORY

Before the Telecommunications Act

Before A.T.&T. was dismantled, the telecommunications industry was basically a heavily regulated monopoly that owned, operated, and maintained the entire telecommunications infrastructure. The government forced A.T.&T. to split itself up into several regional "baby bells," also known as Regional Bell Operating Companies (RBOCs), and one long-distance carrier. The RBOCs inherited the infrastructure that connects the homes with the neighborhood central offices, and as a result controlled the local calling market. Competition appeared in the long distance market with the emergence of Sprint and MCI, but since the RBOCs controlled the last mile of infrastructure, they were able to maintain local monopolies. As one might expect from such an arrangement, the RBOCs, in the absence of competition, were slow moving organizations with little market driven innovation and a history of questionable customer service.

Meanwhile, from 1989 to 1996, the market for Internet access from the home doubled every year. At this time, as is still the case today, the majority of home users were using dial-up modems connected to a standard telephone line to access the Internet. Because the RBOCs owned this infrastructure, they were positioned to control Internet access just as they had been controlling local telephone access. At this point they could dictate how, through whom, and at what price customers would access the Internet.

In an attempt to de-monopolize the RBOCs, in 1996 Congress passed the Telecommunications Act, the first major overhaul of the telecommunication laws in almost 62 years. The goal of the Telecommunications Act was to allow free market entry into any communications business in order to promote competition, reduce regulation, secure lower prices and higher quality services, and to encourage the rapid deployment of new telecommunications technologies. In particular, the Act addressed the critical dearth of local competition by directing the regional telecommunications monopolies to open their infrastructure and unbundle their services for resale to competitors at, as the Act stipulated, "reasonable prices."

 

The Impact of the Telecommunications Act

After the Telecommunications Act was passed, new competitors began entering the market. These new entrants, who became known as Competitive Local Exchange Carriers (CLECs), leased infrastructure from the RBOCs, who, post Act, came to be known as Incumbent Local Exchange Carriers, or ILECs. The CLECs used the infrastructure they leased from the ILECs to provide Local Exchange Carrier (LEC) services to telecommunications consumers, often at cheaper rates than those offered by the ILECs. Examples of CLECs include all of the 10-123 prefix companies that currently advertise so extensively.

During the time after the passage of the Telecom Act, demand for Internet access continued to gain momentum. The ILECs met this burgeoning demand by providing high speed, expensive solutions -- TI, T3 and ISDN -- at high margins to businesses, while home users continued to access the Internet via the slower dial-up modems. Asynchronous Digital Subscriber Line (ADSL) technology was available at this time and offered comparable downstream speeds at lower costs over the same infrastructure as TI and ISDN, and therefore would have better met the needs of the ILECs' home access customers. However, the ILECs chose not to deploy ADSL for fear that it would erode the high margins they received from the aforementioned business solutions.

Some of the CLECs took advantage of this reticence on the part of the ILECs and began implementing ADSL services to homes and businesses. However, in order to implement ADSL, the CLECs had to aggressively pursue their rights under the Telecom Act to collocate equipment in the ILECs' central offices. The CLECs that went this route and began to collocate their own infrastructure alongside that of the ILECs emerged as a new breed of competitor, called data CLECs (also known as "facilities based competitors"). Because of the collocation provision, data CLECs only had to rely on the ILECs infrastructure for access to the last mile, which, as discussed above, was also opened by the Telecom Act. Therefore, companies today, such as Covad Communications Company, which is a data CLEC, are deploying ADSL and are effectively competing with the ILEC’s in the home and business Internet access market. Rather than sit still and watch their share of the broadband Internet access market erode from under them, the ILECs have responded with uncharacteristic speed by offering ADSL themselves. Here, then, is one clear and successful instance in which the Telecommunications Act was instrumental in producing its intended result; because the Act fostered competition, the once complacent, lethargic ILECs were spurred into action to the benefit of their consumers.

Thus far we have concentrated on those companies supplying the underlying infrastructure that provides the last mile connectivity to the end users. But this is not the whole picture. We have yet to discuss Internet Service Providers (ISPs), i.e. the well-known firms such as AOL, Worldnet, Compuserve, etc., that sit between the local infrastructure providers and the Internet backbone. ISPs bundle content and other value-added services such as data caching, web servers, and email facilities and offer them to their customers at competitive prices. ISPs have traditionally been customers of the ILECs, since there are several business telephone lines installed at every ISP facility. The dial-up modems of the ISP customers connect to the ISP’s modems via these telephones lines. The ISP modems then connect to switches that route the signals to the Internet backbone.

ISPs are important because they control so much of how the end user experiences the Internet. For instance the ISPs control what information content their customers see first, and how the billing is done. Before the Telecom Act, RBOCs were positioned to control many of these functions by bundling their own ISP services with their infrastructure. The Telecom Act changed this by mandating that the local infrastructure companies, the ILECs and data CLECs, offer a selection of ISPs to their customers. Furthermore, the ILECs and data CLECs were forbidden to use their infrastructure positions to give their own ISPs an advantage over competing ISPs. This openly competitive environment spurred the entry into the market of numerous ISPs, who now offer ADSL service through ILECs and data CLECs, but who still rely on customers dialing up through modems for the vast majority of their business.

 

CABLE TELEVISION AND BROADBAND INTERNET ACCESSES

With the recent explosion in popularity of the Internet, and the subsequent demand for greater bandwidth access by home users, there is a potential fortune to be made by whomever becomes the dominant provider of broadband access. Seeing this, CATV providers are eagerly making and implementing their plans to enter the broadband market.

A few large companies known as Multiple System Operators (MSOs) dominate the cable television market in the United States. The top 5 MSOs, TCI, Time Warner, MediaOne, Comcast, and Cox, account for over half the CATV market. [1] Each of these MSOs owns many individual, regional cable systems, and typically the MSO enjoys a monopoly in each region it serves.

Though cable operators already have in place extensive distribution networks that include coaxial cables to each subscriber’s home, most cable operators must make substantial, and costly, improvements to their networks before they can offer internet access in a given region.

 

CATV Networks

Historically, a typical cable television network serves a city or region with a size ranging from a few thousand to a few hundred thousand homes. The network has a tree topology, where the cable subscribers can be thought of as the leaves of the tree, and a central station, called the head end (H/E), is the root of the tree. The head end combines television signals from over-the-air and satellite feeds and transmits them across trunk lines that go out to different neighborhoods or sub-regions of the service area. A system of branch lines at the end of each trunk distributes the signals to the individual subscribers in each sub-region, typically 500 to 5000 customers.

In the past cable television networks were constructed using coaxial cable, but now most cable operators have replaced the trunk lines emanating from the H/E with digital fiber-optic cables because they reduce noise on the network and increase capacity (i.e. allowing operators to offer more channels.) The resulting network is often called a hybrid fiber coax (HFC) network. Downstream video signals usually occupy the range between about 50 MHz and 800 MHz of bandwidth, leaving a significant portion of the spectrum below 50 MHz, i.e. 5 MHz to 42 MHz, free. Modern HFC networks use some of this bandwidth to allow for upstream communications from the subscriber's home to the head end, typically for requesting pay-per-view programming. Such networks are called two-way HFC networks.

 

Converting CATV Networks into Data Networks

To offer data services over a cable television network, operators must first upgrade the network in an entire region to two-way HFC. This can be a costly process of changing one way amplifiers throughout the network into two-way amplifiers. Next, the cable operator must make a large investment in equipment in the head end station, and allocate one television channel for downstream communication. The typical cost to make these improvements range from $200 - $250 per home, [2] though a few cable operators have avoided some infrastructure investment to two way HFC by having users send all their upstream data via regular telephone modems in a system known as Telco-Return.

Once these infrastructure investments are made, the only additional cost for adding an additional subscriber is the cable modem at the subscriber’s end (typically about $350.) This is in contrast to ADSL, where with each new subscriber the data CLEC must purchase a new line card at the central office in addition to the DSL modem that must be purchased on the subscriber’s end. Cable modem networks have a smaller marginal cost for an additional subscriber, but a greater up-front fixed cost from the region-wide network improvements that are necessary before anyone can be offered cable access service.

The bandwidth of a cable modem network is asymmetric. The downstream bandwidth varies between 27 Mbps and 40 Mbps, while the upstream bandwidth varies between 500kbps and 10 Mbps (depending on the amount of spectrum allocated for the service, and the noisiness of the network.) Furthermore, the users at the end of each fiber trunk line, which can number between 500 - 5000 subscribers, share both the upstream and downstream bandwidth. In contrast, ADSL bandwidth is not shared among multiple subscribers.

 

Offering Internet Services

Offering Internet service requires more than upgrading the cable network into a data network. It also requires acquiring connectivity to the Internet backbone as well as Servers, Network management tools, billing systems, and security systems.[1] In addition, providing quality service requires having a large amount of popular, multimedia content cached on servers, ideally right at the head end, so that users can get the maximum benefit from their high-speed connections. To provide these services, MSOs almost always partner with a single company specialized in Internet services for cable, or more simply Internet Service Provider (ISP). In several important cases, these ISPs were actually created by the MSOs as separate business ventures. The two most important examples are @Home, and The Road Runner Group.

@ Home was formed by TCI in May 1995, and received subsequent equity investments from Comcast Corp., Cox, and Cablevision. As should be expected, all of the MSOs who have a stake in @ Home partner with it exclusively when offering Internet services. This gives @ Home a potential installed base of 53 million homes, more than half the cable homes in North America. [2]

The Road Runner Group was formed by Time Warner as a separate business. Subsequently, the MSO, MediaOne, formed an alliance with The Road Runner Group, and technology giants Microsoft and Compaq invested a combined $425 million in the venture. Today, subscribers of MediaOne and Time Warner must use The Road Runner Group as their ISP.

 

 

INDUSTRY TRENDS AND AN UNCERTAIN FUTURE

Though it is still early in the race between cable and DSL, cable-modems have a strong early lead. About 20 million homes in North America have access to cable Internet services, and of those, about 500,000 have subscribed compare to only 25,000 DSL users. Cable operators are upgrading their networks region by region, and will spend an estimated $10 billion this year on improvements. [3] However, some people are frustrated that cable companies aren’t making the upgrades faster. [4]

With cable appearing more and more likely to become the dominant broadband access technology to the home, other companies are racing to get a piece of the market. The biggest and most high profile example of this has been the merger of AT&T and the largest MSO, TCI, in early 1998. With hopes of becoming a dominant provider of broadband Internet services, including IP telephony, AT&T acquired TCI for $48 billion, and is planning to spend $5.7 billion on network upgrades. In more recent news, AT&T, Comcast, Microsoft, and America Online are all fighting to purchase another MSO, Media One.

America Online (AOL) may have the most at stake of all the companies fighting for Media One. America Online is the largest ISP for users of dial-up modems, but as users switch from dial-up modems to cable-modems they will have to switch from AOL to the single ISP offered by their local cable company. Without any new government regulations, the only way to be sure that a cable company offers AOL is for AOL to buy the cable company.

But AOL, other dial-up ISPs, and consumer groups, are calling for the government to start forcing cable operators to allow their subscribers to chose other ISPs. However, in the context of the AT&T / TCI merger, the FCC has recently decided that it should not apply "common-carrier" like rules on cable modem networks, because they feel that the broadband market is in a ‘nascent stage’ and must evolve free of intervention. [5]

Yet, the issue is still far from dead. In April, 1999, Stephen Case of AOL testified before the Senate Commerce Committee calling for cable operators to open up to other ISPs, and Senator John McCain has said that he will introduce legislation asking the FCC and the Commerce Department to offer recommendations.

The question is even under scrutiny at the state and local level. ISPs have been encouraging the introduction of state legislation which would force cable companies to open to other ISPs, while the cable industry has been arguing fervently that the states have no right to regulate them. [6] Recently, Multnomah County, OR required that AT&T / TCI open up to other ISPs besides @ Home or else the county would revoke their cable franchise rights to the area. AT&T / TCI promptly sued Multnomah County, and the matter is still before the courts.

Clearly, AT&T / TCI and the other major MSOs appreciate the enormity of the potential market for Internet access over cable, and will fight to make sure that they share the market with as few other players as possible. At the same time, the MSOs are spending billions of dollars to gear up their systems so that more and more people can have access to the Internet via cable. So far the industry has been left to grow unfettered by additional regulation, as the FCC has been weary in bringing cable companies under the fold of the Telecom Act and treating them as they treat ILECs. Is now the time to put the breaks on the power of monopoly MSOs, or would we just be interfering with the growth of an exciting new industry?
