Using Intercom Features

Using the Intercom on MLS- and

MLC-Model Telephones

As an alternative to placing inside calls with Centrex extension numbers, users can place inside calls to other extensions in the system using an [ Intercom ] button on MLS-and MLC-model phones. Using an [ Intercom ] button in this way enables users to keep their primary lines free for calls. This means while a user is waiting for an important call on his or her primary line, the user can make calls to others in the system. Consider the following issues before you decide to use intercom calling:

■People who make intercom calls must know the extension jack numbers for the extensions they call, in addition to the Centrex extension numbers they use normally. (Some equipment features also require extension jack numbers or line jack numbers.)

■People using standard phones normally cannot make intercom calls, although they can receive them. (If, however, no lines are assigned to the standard phone, it defaults to “intercom only.” In that case, it can be used to place and receive intercom calls, but it cannot access Centrex lines and will be restricted to calling extensions within your system.)

■Users cannot access Centrex services (including Transferor Conference) while on an intercom call.

■Recall disconnects an intercom call.

If you choose to make intercom calling available to the people in your company, you may wish to use programmable buttons (see page 4-10or page 5-15),so that people do not have to remember extension jack numbers to use these features. If you do not have any programmable buttons available, you can distribute Form B in Appendix A, which lists Centrex extension numbers and corresponding extension jack numbers, to those people who will use intercom calling.

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.
