Abstract: A terminal system includes first and second terminals (7, 8 and 3a respectively). The terminals can be connected to a central equipment and the first terminals are used for a first functional mode, for example passage control, where persons allotted identification cards can insert information into the common central equipment. The first and second terminals and the central equipment are arranged for a second functional mode, which operates in parallel with the first functional mode. The messages are inserted into the central equipment via the second terminals. Respective first terminals are provided with indicators (6b, 6", 7a, 8b) which can be activated when information relating to a particular person is stored in the central equipment and this particular person, in order to carry out a procedure in the first functional mode, simultaneously activates the first terminal with the aid of his/her identification cards.

Abstract: The central unit of a PABX telephone system includes an associated computer unit that operates to provide visual information to an operator when calls to an extension in the system are to be intercepted. The associated computer unit includes a memory into which a subscriber to the system enters information relating to the reason his calls are to be intercepted, or the like. Any calls to the intercepted extension are routed to the operator, who is simultaneously provided with a visual display of the information stored in the computer memory.
