ABSTRACT:
An improved telecommunication device for simultaneous and independent communication of analog signals and digital data is disclosed. Processing of analog signals enables functions including, for example, message saver, speaker phone, caller identification and fax. Processing of digital data enables functions, including, for example, DSL modem communications, digital voice communications, video communications, and voice-over-data communications. The disclosed system may operate independently or coupled to one or more computers.
