Abstract
Abstract A telephone terminal adapted for business or home use that includes the ability to receive and send facsimiles, a voice answering function and a computer modem. Various input and output devices may be used for the facsimile function. A voice annotated facsimile may be sent and received. At the same time the facsimile is viewed on a video monitor or ordinary television set, an accompanying voice message is heard through the sound system of the monitor or television set. The terminal has an architecture including a central processor and an internal bus structure to which several types of memory, various input-output devices and an interface with the telephone line are connected, among others.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
347 words
A multi-function terminal adapted to be connected to a telephone communications line, comprising: a digital processor connected to a bus structure, a first binary memory connected to said bus structure, wherein at least a portion of said first memory includes audio random access memory, means connectable to said telephone line and said bus structure for identifying voice signals on said telephone line, digitizing such signals and storing the digitized voice signals as data in said first memory, a second binary memory connected to said bus structure, facsimile means connectable to said telephone line and said bus structure for identifying facsimile document data on said telephone line and storing such digitized facsimile data in said second memory, means connected to said bus structure for reading voice and facsimile data from each of the first and second memories, converting means responsive to said reading means for converting said data into a form adapted to be connected with a television set to display the facsimile data and reproduce the voice signals thereon; means responsive to an incoming telephone call to the terminal being answered by a user for causing said facsimile means to operate when either a facsimile identifying tone or a predetermined touchtone code is present on the telephone communications line, means responsive to an incoming telephone call to the terminal going unanswered for said preset number of rings for causing a message stored in said first binary memory to be sent on the telephone communications line, means also responsive to an incoming telephone call to the terminal going unanswered for a preset number of rings for causing said facsimile means to operate when either a facsimile identifying tone or a predetermined touchtone code is present on the telephone communications line during a time that the stored message is being sent on the telephone communications line, and means responsive to said stored message being sent in its entirety without either a facsimile identifying tone or a predetermined touchtone code being received for causing the voice storage meads to operate, thereby to store a voice message in said first memory.
Claim 2
