Adding Modules and Centrex Extensions

If you add new modules to your equipment controller after installation, you will need to identify new extensions and to change Hotline and doorphone extensions (if those devices are installed). Likewise, if you add a Centrex extension after installation, you must adjust programmed settings to accommodate the new extension. You may want to use Copy Settings (#399) to copy some settings—see page 5-11for information on the programmed settings that can be copied with this feature. (If you are using new extensions for auxiliary equipment, see Chapter 7.)

Use the following procedures to adjust the programming for your premises equipment when you add a module or an extension:

■Line Assignment (#301) lets you verify that the primary line is assigned to an extension that you added. If it is not, use this procedure to assign the line. (You can also use this procedure to assign a secondary line to the extension.)

■Line Ringing (Centralized Telephone Programming) specifies when a primary or secondary line will start ringing at the extension.

■Line Access Restriction (#302) determines whether users on each of the lines assigned to the extension can place or receive calls on the line.

■Dial Mode (#201) identifies a line as rotary or touch-tone.

Hotline Phone and Doorphone Extensions

Hotline phones and doorphones should be connected to the last available extension jacks on the last installed 206 module in the equipment controller. If you add modules to your existing configuration and you have Hotline phones or doorphones connected to it, you will need to move the equipment (see page

2-14)and change the following programming procedures:

■Hotline (#603) to identify the new Hotline extension.

■Doorphone Extensions (#604 and #605) to identify the new doorphone extension(s).

■Line Assignment (#301) to remove the primary line from the new Hotline phone and/or doorphone extensions.

NOTE:

Remember to reassign the primary lines to the extension jacks where Hotline phones and/or doorphones were previously installed.

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.
