Telephones

DEFINITY ECS telephones fall into three basic families—Analog, Digital Communications Protocol (DCP), and BRI. These terms describe how each type of telephone communicates with the DEFINITY ECS switch. These families of telephones are designed to accommodate the types of communications various users require. All telephones have touch-tone dialing and the message-waiting lamp for notification of messages.

Telephones for the Global Marketplace

With help from our many global customers, Lucent Technologies has developed the 8400, 9400, 6400 and 6200 series telephones to meet the demand for two-wire telephones in the global marketplace.

8400-Series Telephones

The 8400 digital telephones are versatile two-wire/four-wire Digital Communications Protocol (DCP) telephones with new styling that offer new flexibility and cost savings. They automatically detect whether they are plugged into a two-wire or four-wire digital line circuit card. This is a significant benefit because it provides an easier transition to either a two-line or a four-line environment, therefore reducing wiring expenses and installation adjustments. It also allows you to save space inside the cabinet by using 24-port two-wire boards in place of 16-port four-wire boards.

9400-Series Telephones

The 9400 digital telephones, also known as Europhones, provide inexpensive support for two-wire installations, while still providing a European design. Three models of the 9400 telephones are available in gray and cream white. The 9403, 9410B, 9410D, and 9434 telephones are similar in design and features to the 8400 series.
