Speakerphone Performance Tips

The speaker and microphone on your MLS-34D, MLS-12D, or MLS-12 telephone is controlled by a sensitive sound-activated switch. Room acoustics and background noise can affect the proper operation of the speaker. To ensure that your speaker works effectively, follow these guidelines:

■Avoid placing your phone in areas with high background noise caused by loud voices, radios, printers, copiers, typewriters, other noisy office equipment, and heater and air conditioning fans.

■Avoid rustling papers near the microphone (lower right corner of your phone).

■Avoid talking before the other person is finished speaking. When you both talk at the same time, only one person’s voice comes through.

■When talking, always face your phone and stay within two feet of it.

■Place your phone at least six inches away from the edge of your desk.

■If you have difficulty hearing the other party, increase the speaker volume. If the difficulty persists, lift your handset to continue the conversation.

■In conference rooms, a separate speakerphone (such as the AT&T S203 Speakerphone) is recommended, since the built-in speaker on an MLS- or MLC-model phone is designed for individual use.

Standard Telephones

In addition to MLS- and MLC-model phones, you can connect industry-standard touch-tone or rotary phones to your equipment controller. (This includes some phones with programmable buttons or built-in calling features, called feature phones.) You can also combine standard phones on the same extension with an MLS- or MLC-model phone or other device without using expensive adapters or connectors.

At least one standard phone should be available for use in the event of a power failure (for more information, see “Power Failure Operation” on page 2-4), and you should use a standard phone for a Hotline phone (see page 2-5).If you use a standard phone, keep these guidelines in mind:

■Power Failure Backups. In the event of a power failure, standard phones at extension jacks 10, 16, 22, and 28 can place and answer calls on lines at line jacks 01, 07, 13, and 19, respectively. MLS- and MLC-model phones, which require electrical power, will not work. You can connect a standard phone in combination with an MLS- or MLC-model phone at power failure extensions, or you can simply keep spare standard phones at those extensions to serve as replacements in case of a power failure.

■Placing calls. To dial an outside call, just lift the handset and make the call; precede the phone number with your Centrex dial-out code if you have one. To dial an inside call to another extension, dial the Centrex extension number. Standard telephones can access Centrex services, but not equipment features.

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.
