Abstract: SECURITY CONTROLLED INFORMATION EXCHANGE SYSTEM security con-trolled information exchange system for controlling the orderly exchange of information between two or more users under primary control of security identifiers. Each user is set up with a local user identifier (LUID) and a number of remote user identifiers (RUID). Also, associated with selected ones of the RUIDs, are jobs which are to be communicated. A user initiates communication transfer by forwarding to another terminal its LUID and the receiving user compares the received LUID with its list of RUIDs and if a compare is made, the receiver forwards its own LUID to the initiating party. If a compare is not made, it disconnects. The initiating party then compares the LUID which has been forwarded to it with its list of RUIDs and if no compare is made, it disconnects. If a compare is made, however, it holds onto the line and the called party then sends the jobs which are associated with the RUID which corresponds to the LUID which it received. Each RUID may be associated with a single unique job which may be forwarded to a calling user or may be associated with a number of jobs which may be chained and automatically forwarded to the calling user. In addition, a number of RUIDs may be associated with the same job or with selected ones of jobs in the complete job list.

Abstract: A method of selectively communicating data between users in a communication system comprising the steps of: assigning a local user identifier to each user of said system; transmitting the local user identifier of a calling user to a called user; comparing the local user identifier of the calling user with at least one identifier of a predetermined remote user assigned to the called user; and if the comparison is positive, transmit the local user identifier of the called user to the calling user to establish an exchange of data between said called user and said calling user.

Abstract: A data communication system incorporating control means at the transmitting station for selecting which of several output devices at the receiving station will record the transmitted data. Selection of the output device governs the data rate of the transmitted information. Error control means at the receiving station operates to signal the transmitting station to select a predesignated output device for recording messages previously received in error on another output device. The error control means is responsive both to errors induced by the communication channel and recording errors induced by the output device.
