Dialing Restrictions: An Example

The following example shows how the equipment controller checks dialing restrictions and permissions when a user places a call. The controller checks the number dialed against all the equipment dialing restrictions that apply to the extension placing the call. When the number dialed passes a restriction, it goes to the next one, if necessary. When a number violates a restriction, the call is stopped and the user hears a reorder (fast busy signal) tone.

In this example, the user is dialing on a line that has Outgoing Call Restriction set to “local only.” In addition, the extension has an Allowed Phone Number List that contains a “1800” entry. Notice that the equipment controller keeps checking the number until it finds a valid reason to complete the call or stop it.

Yes, call dropped and reorder tone given

 

NOTE:

If you have Centrex dialing restrictions on a line and also program equipment dialing restrictions for the line or an extension where the line is assigned, both the Centrex and equipment restrictions will apply to the line or extension.

However, equipment dialing permissions will not override Centrex restrictions.

Auxiliary Equipment

You can use a variety of auxiliary devices with your phone system, either by connecting them directly to the equipment controller or by connecting them to extensions. This chapter includes information on auxiliary equipment that requires programming, including Hotline phones, loudspeaker paging systems, doorphones, call reporting devices (SMDR), fax machines, and music-on-hold sources. Chapter 7 includes further information about this equipment and additional equipment that does not require programming (including answering machines, modems, and credit card scanners). In addition, Chapter 2 includes information about connecting auxiliary equipment to your equipment controller. Programming procedures are explained in detail in Chapter 5.

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.
