■The equipment controller can store a maximum of 80 System Speed Dial numbers (dial codes 20-79).

■System Speed Dial numbers must be programmed from an MLS-34D or MLS-12D display phone at extension jack 10 or 11.

■If you must include a dial-out code before dialing an outside number, include the dial-out code in the programmed Speed Dial number.

■It is recommended that you do not store Centrex feature codes as System Speed Dial numbers. (If the equipment controller sees an asterisk in the Centrex feature code, it will interpret the number as a Marked System Speed Dial number and will not dial the asterisk.)

Appendix A provides a form on which to record Speed Dial numbers. You should record all System Speed Dial numbers on the top of that form and give a copy to each user with an MLS- or MLC-model phone.

You may decide to use Centrex speed dialing on all lines for the numbers that all users need often; Centrex speed dial numbers can be dialed from both standard phones and MLS- or MLC-model phones.

Frequently-dialed numbers can also be programmed onto Auto Dial buttons on MLS- or MLC-model phones for even faster one-touchdialing.

Personal Speed Dialing

Personal Speed Dial numbers are available only at the extension for which they are programmed (for users who have MLS- or MLC-model phones). The following notes apply to Personal Speed Dial numbers:

■Personal Speed Dial numbers are stored in an extension’s memory and are for the private use of that extension.

■Each extension can have a maximum of 20 Personal Speed Dial numbers (dial codes 80-99).

■Personal Speed Dial numbers can be programmed from an MLS-34D or MLS-12D phone at extension jack 10 or 11, or from the user’s extension.

■Personal Speed Dial numbers do not have to be used to store telephone numbers. Like programmable buttons, they can also be programmed to provide faster access to equipment and Centrex features.

■If you must include a dial-out code before dialing an outside number, include the dial-out code in the programmed Speed Dial number.

Users can record their Personal Speed Dial numbers on the Quick Reference cards for their phones or on the bottom of the Appendix A “Speed Dial Numbers” form.

Calling Restrictions

Once a caller has access to a Centrex line, Centrex can provide dialing restrictions for the line. Centrex restrictions apply to all appearances of a line—controlling calling on all phones that have that line assigned, whether the line is assigned as a secondary line or as a primary line.

The dialing restrictions that are available through your equipment controller can provide additional flexibility, letting you control a particular extension’s access to

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.
