ISDN 7505 Modular Terminal

The 7505 Modular Terminal is used with the Integrated Services Digital Network (ISDN) commun- ication system through a 4-wire ‘‘T’’-interface. The modular 7505 is a voice terminal when equipped with a Voice Only Module (VOM). As a telephone, it offers programmable buttons, fixed feature buttons, a Message light, touch-tone dialing, and a built-in, programmable speaker- phone or SPOKESMAN loudspeaker. The speakerphone can be programmed at the terminal by the user for one of three states: On, Disabled, or SPOKESMAN loudspeaker. The 7505 can be equipped with an optional Asynchronous Data Module (ADM) that provides the user with simul- taneous voice and data capabilities. The 7505 equipped with the ADM offers the same voice capabilities as the 7505 equipped with the VOM, plus it allows attached data terminals or per- sonal computers to send and receive data through the digital network.

Note: The 7505 voice terminal is no longer being manufactured.

Applications
