If a password is programmed, users in the Night Service Group must enter it before dialing outside telephone numbers or Centrex extension numbers (with some exceptions, described on page 5-13).Intercom calls can be made without using the password (see Appendix B). The password must be entered to turn Night Service on or off. A System Password cannot be entered from a standard phone or from an MLC-6 cordless phone.

Speed Dialing

Centrex may provide speed dialing for some or all of your Centrex lines. However, you can store additional numbers using the Speed Dialing feature available with your premises equipment.

Speed Dial numbers are outside telephone numbers or Centrex extension numbers that a user can dial automatically by pressing [ Feature ] and a two-digit code.

NOTE:

The Speed Dial numbers available with your premises equipment can be dialed only from MLS- and MLC-model phones.

System Speed Dialing

You can program frequently dialed phone numbers—such as suppliers, repair services, customers, or other business associates—so that all users in the system with MLS- and MLC-model phones can dial them by pressing three buttons: [ Feature ] plus a two-digit code.

The following notes apply to System Speed Dial numbers:

■System Speed Dial numbers are stored in the equipment controller, so a user at any MLS- or MLC-model phone can dial them provided that a Centrex line is assigned to the extension.

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.
