Other Devices

You can connect other devices to your equipment controller, but only specific models are compatible with the equipment controller. (See Appendix C for product ordering information.)

■Call accounting devices and printers allow the system manager to print call reports. The call accounting device or printer connects directly to the primary processor module in the primary carrier. See “Call Reporting Devices (SMDR)” on page 7-7 for more information.

■Doorphones allow visitors to alert up to five extensions at once by pressing a button on the doorphone; the person who answers a doorphone call can then use the phone to speak to the visitor at the doorphone. The equipment controller supports up to two proprietary doorphones, which can be installed indoors or outdoors. A doorphone is especially useful for providing access to offices or departments after hours. For example, you can install a doorphone outside your building entrance to allow visitors to alert telephones inside the building when the receptionist is not there and the front door is locked.

■Loudspeaker paging systems allow you to broadcast a message over a large area, by connecting the paging system directly to the PAGE jack on the primary processor module. The equipment controller supports all AT&T paging systems. For information on how to use a loudspeaker paging system with the equipment controller, see page 6-17.

■Music-on-hold systems allow you to play recorded music to callers while they are on hold, by connecting the music-on-hold system to the primary processor module. The equipment controller supports the AT&T Magic on Hold system and most models from other manufacturers.

■Extra alerts are strobes, lights, chimes, horns, or bells that light or ring when calls come in. For example, you can use an audible alert (chime, horn, or bell) to replace a phone ring in a noisy area, such as a factory. Similarly, you can use a visual alert (strobe or light) to replace a phone ring in a quiet area, such as a library.

■Electromagnetic Interference (EMI) filters allow you to block “noise” generated by a nearby radio station, as well as most electrical devices. The equipment controller supports the AT&T Z300A EMI Filter.

■Uninterruptible Power Supply (UPS) allows full equipment operation during a power failure. The equipment controller supports the AT&T 360VA UPS.

■In-Range Out-of-Building (IROB) protectors are required to prevent electrical surges from damaging your equipment when phones are installed in another building, but on the same continuous property. The equipment controller supports the AT&T IROB protector, which provides coverage over a distance of 3,000 feet for standard phones and 1,000 feet for MLS- and MLC-model phones. (For installation instructions, refer to the booklet packaged with the IROB protector.)

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.
