■Marked System Speed Dial Numbers can be dialed from any extension. System Speed Dial numbers are telephone numbers that a user can dial automatically by pressing [ Feature ] (or [ # ] on a standard phone), followed by a two-digit code. “Marking” a System Speed Dial number when the number is programmed lets any user in the system dial it, overriding any equipment dialing restrictions for the extension.

■System Password (#403) creates a password that, when entered at any MLS-model phone, overrides equipment dialing restrictions for the duration of a call. This means that a person who knows the password can make a call from a restricted extension. If you define a System Password, turning on Night Service also restricts calling for the Night Service Group. See page 4-13 for details on Night Service.

You can use the following procedure to override all equipment dialing restrictions, except Line Access Restriction and Night Service with a System Password:

■Allowed Phone Number Lists (#407) allows you to create lists of numbers that specific extensions are allowed to dial. Even if an extension’s settings for Outgoing Call Restriction and Disallowed Phone Numbers would normally prevent the extension from dialing a number, defining the number as an Allowed Phone Number lets the extension dial it. (For example, if you put 900 numbers on a Disallowed List but want users to be able to call a specific 900 technical support hotline, put that number in an Allowed List.) For information on entering telephone numbers into lists, see “Entering Telephone Numbers into Lists” on page 4-18. (For programming information, see page 5-12.)

The equipment controller stores as many as four different Allowed Lists of up to 10 numbers each. After creating Allowed Lists, use the Allowed List Assignments (#408) procedure to assign one or more of the lists to a specific extension.

Entering Telephone Numbers into Lists

This section explains how to enter telephone numbers into Disallowed Phone Number Lists, Allowed Phone Number Lists, and an Emergency Phone Number List.

To store a telephone number, dial the number as you would normally; but leave out the dial-out code if you must normally dial one to place outside calls. However, for toll calls you should include a toll call prefix such as 1 or 0 (if you must dial one to place toll calls) and the area code.

For example, to prevent all calls to a specific area code, you need only enter the toll call prefix and the area code in a Disallowed List. When a user at an extension to which the list is assigned tries to dial a number in that area code, the user hears a reorder tone (fast busy signal) as soon as they dial the area code, before they have a chance to dial the rest of the number.

When you store a telephone number in a list, you can also use the “wildcard” character to stand for any single digit in a phone number. To enter the wildcard character, press [ Hold ]; the wildcard appears as “!” on the telephone display.

For example, if you want to prevent users from placing calls to any numbers beginning with 202, 212, 222, 232, 242, 252, 262, 272, 282, and 292, you can enter each number in a separate list entry, or you can combine them into one

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.
