In the event of a power failure, any calls in progress are lost; call records for those calls are also lost.

Intercom calls are not recorded, but inside calls made using the Centrex extension number are.

If you place a call on hold and the caller hangs up, the call is considered complete and the record is sent to the call reporting device.

Serial Printers

A 355AF adapter lets you connect a serial printer, such as AT&T’s 572 Serial Printer, to the primary processor module. If you connect a printer, make sure the printer’s switches are set as follows (refer to the printer’s instructions if you need help):

1200 baud

No parity

8 data bits

2 stop bits.

The call reporting feature also supports XON/XOFF protocol, carriage returns, and line feeds.

Call Accounting Devices

You can send call information to a call accounting device if you want to further analyze call activity. The device stores rate table information and processes the call information it receives into meaningful reports that can help you optimize your communications system. For example, you can use it to determine the best combination of local and long distance lines.

The call accounting device connects directly to the SMDR jack on the primary processor module and can also print out daily reports that include summaries by hour, facility, and extension jack number. Refer to the manual provided with the call accounting device for instructions on connecting it to your equipment controller.

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.
