with Centrex Services

 

Overview

This chapter explains how your premises equipment works in conjunction with your Centrex services. The following topics are discussed:

■Line assignments and ringing

■Line and extension numbering

■Popular Centrex services

■One-touch access to Centrex services.

When you have installed your premises equipment as described in Chapter 2, the equipment controller sets up your system (using default or “factory” settings) to work smoothly with your Centrex services. For example, the controller automatically distributes the Centrex lines connected to your equipment controller, assigning a primary line to each system extension, and sets all primary lines for immediate ringing. This means that anyone (inside or outside the Centrex system) can dial an extension directly, simply by dialing the phone number. (See “Primary and Secondary Lines” on page 1-5 for more details.)

NOTE:

This guide describes only the operation of your premises equipment; for information on Centrex services, see the Centrex documentation provided by your local telephone company.

If you wish to change the defaults described in this chapter, see Chapter 4 (for information on the options that are available) or Chapter 5 (for equipment programming procedures).

II specifications

AT&T II, a pivotal case in the landscape of telecommunications regulation, emerged from the expansive antitrust actions against the American Telephone and Telegraph Company (AT&T). Following World War II, AT&T had established itself as a telecommunications behemoth, monopolizing the market. The ramifications of this dominance spurred a significant shift in regulatory measures, leading to the dissolution of the Bell System in 1984, which consisted of AT&T and its regional operating companies.

One key feature of AT&T II is its emphasis on promoting competition in the telecommunications sector. The court's decision aimed to dismantle the monopolistic practices that had stifled innovation and restricted consumer choice. By encouraging competition among various service providers, the ruling paved the way for an environment where new technologies could flourish.

The technologies that emerged post-AT&T II significantly transformed the telecommunications landscape. The introduction of new digital switching systems allowed for improved call quality and increased network efficiency. The evolution of fiber-optic technology also played a crucial role, enabling faster transmission speeds and greater data capacity. Moreover, innovative services, such as mobile telephony and broadband internet, proliferated as competition increased.

Another characteristic of AT&T II is its focus on accessibility and consumer protection. The ruling mandated that telecommunications services be available to a broader swath of the population, ensuring that underserved communities had access to essential communication services. This shift not only democratized access but also laid the groundwork for the modern internet revolution, fostering the growth of the digital economy.

The impact of AT&T II can also be seen in the regulatory frameworks that followed. The Federal Communications Commission (FCC) adopted policies aimed at enhancing market transparency and ensuring fair practices among competitors. These regulatory changes helped to create a more equitable playing field, allowing smaller companies to compete against established giants.

In summary, AT&T II marked a turning point in telecommunications history, characterized by a focus on competition, technological advancements, and consumer protection. The dissolution of AT&T's monopoly allowed for the rapid evolution of technology and services, ultimately benefiting consumers and fostering an environment ripe for innovation. This ruling not only redefined the telecommunications industry but also set a precedent for how markets are regulated in the United States.
