To set up loudspeaker paging:

Connect a loudspeaker paging system to the primary processor module of the equipment controller, as described on page 2-13.

To let a user access loudspeaker paging with one touch, install an MLS- or MLC-model phone at the user’s extension and program a button with the feature code for loudspeaker paging (see page 5-16).

To set up paging to MLS-model phones:

Install MLS-model phones in locations where you want employees to hear voice-paging announcements.

To set up group paging, first use Calling Group Extensions (#502) to assign extensions to Calling Groups. Exclude extensions with fax machines, Hotline phones, doorphones, or other auxiliary equipment from Calling Groups. You can set up as many as four Calling Groups.

Program paging buttons on MLS- or MLC-model phones, so that people can easily page groups or individuals. (Program these features onto buttons so that users will not have to remember group numbers or extension jack numbers.) See page 5-16for programming information.

Optional Features

for Premises Equipment

In addition to the features you have available through Centrex, you can use equipment features to support your company’s call handling. This section discusses some of the most useful features; for a complete listing, see Table 4-6on page 4-25. Programming instructions are in Chapter 5.

Night Service

The Night Service feature allows you to change the way a group of extensions operates after normal business hours. When Night Service is turned on, all incoming calls will ring immediately the extensions in the Night Service Group (#504), even if Line Ringing for those extensions is set for “delayed ring” or “no ring” during normal daytime use. For Night Service to work properly, all lines should be assigned to the extensions in the Night Service Group.

Example: The security guard at Company X has a standard single-line phone with all of the lines for the company assigned to it. The secondary lines are set to “no ring,” so that the guard only receives calls on the primary line for the extension during the day. When Night Service is on, however, all lines ring immediately at the security desk, to provide backup call answering when there is no one available in the office.

Table 4-4shows the programming settings that must be entered to set up Night Service. The first column shows the name of the programming procedure or function. System Programming procedures include the procedure number in parentheses—for example, “Line Assignment (#301).” The remaining columns show the required and optional settings for Night Service.

AT&T II manual Optional Features For Premises Equipment, Night Service

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.
