■Use Doorphone Alert Extensions (#606) to identify up to five extensions that will be signalled by a doorphone when the doorphone button is pressed.

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

Call Reporting

Centrex may provide call reporting and accounting services. However, if you do not subscribe to this service, you can install call accounting devices and printers that allow you to print call reports. To get a better idea of the call reporting capabilities available with your premises equipment, see “Call Reporting Devices (SMDR)” on page 7-7.

To set up a call accounting device or printer for call reporting, install the equipment according to the directions on page 2-13.Then use SMDR Record Type (#608) to specify the type of calls that you want to record for call reporting.

Fax Machines

Fax Machine Extensions (#601) lets you identify an extension on which a fax machine is installed. If you also program the fax extension as an Intercom Calling button (by storing the extension jack number on a programmable button with a light), the button will show the status of the fax machine when it is in use or needs paper. Do not assign a fax machine’s primary line to any other extension. See “Fax Machines” on page 7-1 for more details on setting up and using fax machines.

Music on Hold

Music on Hold (#602) activates or deactivates an optional music-on-hold system, which can be connected to an RCA jack on the equipment controller (see page 2-13).

Identifying the

Equipment Features You Need

Table 4-6shows the optional features available with your premises equipment. Make a check mark in the rightmost column to indicate whether you need the feature shown on that row. The page numbers where you can find programming information are shown in the “For instructions, see. . .” column. Two types of features are included in the table:

■System Programming. Features that are available through System Programming are identified by the procedure code that is used to program the feature (# and three digits). For these features, the “For instructions, see . . .” column of Table 4-6shows the words System Programming.

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.
