Hotline Phones

The Hotline (#603) procedure allows you to identify Hotline extensions and alert extensions, so that when a person lifts the handset of a Hotline phone, the alert extension rings automatically. You can specify one alert extension for each Hotline phone, and you can designate as many Hotline phones as you wish. In addition, the loudspeaker paging system can be designated as the alert extension for a Hotline phone, so that a Hotline phone can be used to make announcements over the loudspeaker.

Example: A market installs one Hotline phone at its meat counter. When a customer picks up the Hotline phone, the butcher’s phone rings. Another Hotline phone is installed at a cash register and the loudspeaker paging system is identified as the alert extension, so a sales clerk can pick up the Hotline phone to request a “price check” over the loudspeaker.

To set up a Hotline phone:

■Connect the Hotline phone to the last available extension jack on the equipment controller. (A standard touch-tone or rotary phone is recommended at the Hotline extension.)

■Use Line Assignment (#301) (see page 5-11)to remove the primary line assignment from the Hotline extension jack. If you do not remove the primary line assignment, the Hotline phone will not work.

■Use the Hotline (#603) procedure (see page 5-13)to identify the extension where the Hotline phone is located; the same procedure identifies the alert extension (or loudspeaker paging system) that will be signalled when the Hotline phone is used.

■Make sure the Hotline phone extension is not in the Pickup Group (#501), Calling Group (#502), Night Service Group (#504), or Hunt Group (#505). (See page 5-13.)

Doorphones

You can specify up to five extensions that are alerted when a visitor presses the button on a doorphone. If the alert extension is an MLS-model phone, the doorphone signal is a distinctive ding-dongto distinguish it from regular calls. The person who answers a doorphone call can then use his or her phone to speak to the visitor outside the office. You can install two doorphones if you need them. (If you install two doorphones, they each have a different signal at MLS-model phones.)

Example: You can install a doorphone outside your building entrance (or in the hallway outside your suite) to allow visitors to signal telephones inside the office when the receptionist is not there and the front door is locked.

To set up doorphones:

■Connect the doorphone to the last available extension jack on the equipment controller.

■Use Line Assignment (#301) to remove the primary line assignment from the doorphones’ extensions.

■Use the Doorphone Extensions (#604 and #605) procedures to identify the extensions on which doorphones are 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.
