Part V

Appendixes

In this part . . .

Unlike the human body (where some folks consider the appendix a useless part), the appendixes you

find here actually provide some great information.

When it comes time to look for a competent VoIP partner, you’ll find the information in Appendix A quite helpful. It ranks the top ten VoIP manufacturers, in order of revenue.

Are you befuddled by an unfamiliar word you’ve run across? Relax — chances are good that you can find the telecom or VoIP term you need in the glossary.

Appendix A

VoIP Providers

The VoIP provider market has been growing in leaps and bounds since AT&T announced in January 2004 that it was abandoning traditional car-

rier services as a way of doing business. What they were abandoning was the way of doing business outlined in the Telecommunications Act of 1996. The act defined ILECs, or Incumbent Local Exchange Carriers. ILECs (or simply LECs) owned all the physical lines in a given area. Everyone else had to

go through ILEC to get any kind of access. The act also defined CLECs (Competitive Local Exchange Carriers). CLECs leased access lines at wholesale from the ILECs.

The customers, of course, ultimately paid the bill. Either they could get lines directly from an ILEC, or they could get them from a CLEC, who in turn got them from the same ILEC. Many analysts would say that the act had a beneficial effect on the marketplace, particularly with interstate long-distance costs. But in local markets, ILECs dominated because, no matter what, they had a piece of the action. And because ILEC controlled the actual physical installation of the access lines, any shortcomings in their service had a negative impact on the CLEC’s customers.

CLECs, of which AT&T was one, are now using packet-switching protocols to provide VoIP services over their existing networks, rather than leasing POTS lines from ILECs at wholesale pricing. ILECs are now in a position where they could lose significant revenue. The fewer POTS lines installed by ILECs, the less revenue they have from wireline services.

For CLECs, the way is clear. Should they use circuit-switched POTS services at wholesale pricing, which they then mark up for their customers? Or do they use packet-switching services with VoIP, at a fraction of the wholesale price, using their own existing networks and offering their customers a much better value?

It is no small wonder why in the past six months the ILEC powers-that-be have sought to acquire the largest CLECs that offer VoIP. As a result of these changes in the marketplace, many argue that the corporate and consumer buying public will lose some of the choices they had when the lines between ILECs and CLECs were more clear. I disagree. With the inception of VoIP and the maturation of wireless, the choices for telephony and video services are increasing.

236 Part V: Appendixes

As a potential consumer, you need to know who is offering VoIP carrier services and who is offering the leased access lines you need to build or upgrade your VoIP network. Table A-1 lists the top ten VoIP carrier providers, ranked in order of gross revenue.

The first six carriers and number eight — Verizon, SBC, AT&T, Sprint, BellSouth, MCI, and Qwest — are able to lease or release any of the transports or transport services covered in Chapters 4 through 7. For example, to set up or upgrade a private dedicated network to run VoIP (see Chapter 7), your company most likely would work with one carrier to acquire the transports at each of your locations. The carriers can also offer VoIP services.

The seventh carrier, Comcast, is also the country’s largest cable provider. The cable industry is not regulated, so the rules of the Telecommunication Act of 1996 do not apply to their cable services in the same way. They are permitted to be CLECs for the purpose of offering other services. For instance, if they lease cable service to your home, you may also get POTS service over that cable. For them to offer you POTS, they have to have transports into the PSTN. They can also lease VoIP services to you that run over your cable line.

The ninth carrier, Nextel Communications, is a cellular company, and the tenth, DIRECTV Group, is a satellite carrier company that offers broadband DSL to the consumer market.
