ATT Definity ISDN 7506 Telephone Black is a refurbished ISDN voice terminal designed for compatible ATT Definity communications environments. The 7506 provides business telephone functionality through programmable buttons, fixed feature buttons, and a message indicator. When equipped with the appropriate ADM, the terminal can also provide simultaneous voice and data communications from a single desktop location.
With an ADM installed, compatible data terminals or personal computers can send and receive data through an ISDN network while maintaining voice communications capabilities. This combination makes the 7506 useful for organizations maintaining established Definity installations that require both telephone and data connectivity.

Voice and Data Communications
The ATT Definity ISDN 7506 Telephone Black was designed for business environments requiring more than basic telephone functionality. With the appropriate ADM, the terminal can provide an interface for attached computers or data terminals, allowing voice and supported data communications to operate from the same workstation.
Its support for multiple data communications methods, programmable memory numbers, configurable data profiles, and standard AT commands makes the 7506 suitable for maintaining compatible legacy Definity applications. For organizations with established ISDN equipment, a refurbished 7506 can provide a practical replacement for a failed or damaged terminal.
