Preparation. See page 5-4, “Telephone Programming Procedures,” to find out how you prepare for Telephone Programming.

Instructions. To program a phone from extension jack 10 or 11, use the instructions at the top of page 5-15.To program at the extension, use the instructions at the bottom of page 5-16,then go to the appropriate box on page 5-16for instructions on programming an individual feature.

Brief summaries of all programming procedures are also provided on the inside back cover of this book.

Terminology

The following terms are used in this chapter. In addition, you may wish to review the “Terminology” section of “About This Guide,” which defines basic terms used throughout this guide, or the Glossary, which defines all terms.

Auto Dial

A programmable telephone button that lets you dial a series

button

of digits simply by pressing that button. An Auto Dial button

 

can be used to store a Centrex feature code or a telephone

 

number so that it can be dialed with one touch. See also

 

Equipment feature button and Programmable button.

Button-Down

A system-wide setting that causes incoming calls on

Mode

secondary lines to flash, but not ring. A user must press the

 

line button down to pick up the call. This feature enables the

 

equipment to imitate the way lines ring at extensions on key

 

telephone systems, such as the 1A Key System.

Centralized

A method of telephone programming that lets you program

Telephone

individual extensions in the system from an MLS-34D or

Programming

MLS-12D phone at extension jack 10 or extension jack 11.

 

Centralized Telephone Programming is an alternative to

 

Extension Programming.

Equipment

A feature provided by your equipment controller (as opposed

feature

to a service provided by Centrex).

Equipment

A programmable telephone button on an MLS- or MLC-model

feature button

telephone that enables you to access an equipment feature

 

simply by pressing that button. See also Auto Dial button

 

and Programmable button.

Extension

A method of telephone programming that lets users program

Programming

their own extensions from their MLS- or MLC-model phones.

 

Extension Programming is an alternative to Centralized

 

Telephone Programming.

Premises

The AT&T equipment controller and MLS- and MLC-model

equipment

telephones that you purchased as part of your system, plus

 

all other telecommunications devices that are connected to

 

your equipment controller. For purposes of this guide,

 

premises equipment does not include any equipment that

 

connects directly to Centrex lines without going through the

 

equipment controller.

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.
