The existing telecommunications infrastructure offers ~nteroperability between LECs and Arcs for traditional circuit switched and dedicated services and among peers at agreed-upon exchange points in the case of the Internet. The evolution of commercial telecommunications services does not guarantee that competing service providers wait ~nteroperate.

Telecommunications Service Providers The telecommunications infrastructure is composed of an extensive set of physical communications facilities owned by a relatively small set of telecommunications companies. The LECs end the Arcs provide most of He bulk of the actual physical facilities that deliver telecommunications services.

Numerous service providers, best represented by the Internet community, have capitalized on this infrastructure to provide effective ~nforrnation services. Telecommunications Services It is also worthwhile to briefly review the services delivered by the service providers.

to the private line to support virtually any type of service. Large users of telecommunications use private line services as the cost of dedicated services tends to be high relative to that for switched services such as voice (note that while customers only pay for voice services when they are In use, private lines incur flat rate charges independent of usage)

i, The vision of an ATM-based network also offers significant advantages to the user community. Existing telecommunications services mirror Me carrier networks, where multiple independent networks share a common time division substrate to deliver separate services.
|
From page 150... ...
For example, voice or switched services and private line and Internet services all support interconnection between users connected to different carrier services. Meanwhile, private networks and emerging services tend to struggle for ~nteroperability beyond specific provider boundaries.
|
From page 151... ...
The expansion of global services by primary carriers has created direct competition between service providers and resulted in reduced desire for ~nteroperability.

From page 152... ...
Attributes of Service Provider Interconnection The preceding profiles of major interconnection methods suggest several key attributes for service provider interconnection.
|
From page 153... ...
In addition, as telecommunications services have become more of a commodity, service providers have looked for ways to differentiate their services through technological improvements as well as in combination with information services. The Internet is undergoing a parallel change where the trend toward commercialization wail create competitive relationships among previously complementary entities.

From page 154... ...
The major Sacs have already captured prominent positions In the commercialization of the Internet. As Internet services reach traffic/revenue levels comparable to those of mainstream carrier services, service providers wall move toward settlement scenarios that Ivy} once again favor the larger providers.

and the mteroperability among service providers. Prototype models for cattier interconnection for various services, technologies, and special user communities should be established to detenn~ne feasibility and preferred approaches for deployment In the future Nit.
