Example:

A person at a covering extension who screens another extension’s calls may need an Intercom Calling button for the covered extension (possibly with voice paging) to announce calls and visitors. The lights beside the Intercom Calling button show when the covered extension is busy.

To program an Intercom Calling button, see page 5-15.

Paging

Two equipment features enable you to page system extensions. For ease of use, you should store these features on the programmable buttons of MLS- or MLC-model phones, so that a user can page a phone or group of phones simply by pressing the programmed button.

The following types of paging are available:

■Paging over an optional loudspeaker paging system, which may be connected to the equipment controller. You access the loudspeaker by dialing an equipment feature code, which can be programmed onto a button on an MLS- or MLC-model phone.

■Paging over MLS-model phones, which have built-in speakers, provides an inexpensive alternative to a loudspeaker paging system. By dialing the appropriate feature code, you can page an extension (Voice Paging) or a Calling Group (Group Paging). Paged extensions beep (at any extension that has an MLS-model phone) to indicate that the speaker has been turned on; then your voice is heard over the speaker. When a caller picks up the page (by picking up the handset or pressing [ Mic ]), the page becomes an intercom call between the person who paged and the person who picked up. (Because it is an intercom call, the call does not tie up the user’s primary line.)

The feature code for Group Paging, or for paging a particular extension, can be stored on a telephone button for one-touch dialing. (Paging an extension requires that the extension jack number be stored on the telephone button.)

If you are busy on a call when someone tries to voice page your extension, your phone rings instead of turning on the speaker for the page. If you try to voice page an extension where a standard phone or MLC-6 is connected, the phone rings.

Example: A car dealership puts all extensions for the sales staff into a Calling Group. To talk to salespeople, the sales manager simply presses a programmed button on an MLS- or MLC-model phone. A paging intercom call goes to the Calling Group. The phones’ primary lines remain free for incoming calls.

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.
