Programmable button

A telephone button that can be set up to access a feature. On MLS- and MLC-model phones, programmable buttons can be used as Auto Dial buttons (for one-touch dialing of Centrex feature codes or telephone numbers) or equipment feature buttons.

System Programming Procedures

In general, you can program the premises equipment in one of two ways:

■Direct Method. With this method, you access a programming procedure by dialing the code for that procedure.

■Cycle Method. With this method, you cycle through the procedures in numerical order by pressing [ Next Procedure ] or [ Prev Procedure ] (see the programming overlays on pages 5-5and 5-6).This method is best for programming the premises equipment for the first time or for changing a series of related settings.

NOTE:

You can be talking on the phone while you program. This is useful if you need to talk with someone at the AT&T Helpline about programming. However, you must call before you enter programming mode, and you must use the handset to talk, not the speaker and microphone.

Review the following two procedures before you start to program, as they may facilitate your programming task:

■Button-Down Mode (#723) adjusts ringing for all phones connected to your equipment controller. Designed for people who are accustomed to 1A Key systems, this feature causes incoming calls on secondary lines to flash (but not ring). To pick up a call, a user must press the line button. This prevents users from accidentally answering incoming calls on secondary lines when they are trying to place calls on their primary lines. Only the receptionist’s phone at extension jack 10 follows the premises equipment defaults (“immediate ring” for the primary line and “delayed ring” for secondary lines). The default for Button-Down Mode is “Not Active.”

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.
