Abstract: A method for adapting supplementary equipment, such as automatic answering equipments, intercommunication stations, automatic dialers and the like, to an analog telecommunications terminal as well as to a technical device for the implementation of the method. The supplementary equipment is inserted into the voice-communication path of the terminal in that the network access line of the terminal is accessed and in that the picked-off incoming voice signal is sent to the supplementary equipment and to a voice input/output unit electrically separate from the terminal equipment. Outgoing signals are generated by the supplementary equipment and/or by the voice input/output unit and are, in turn, fed into the network access line. Conversely, dialing and other control signals are transmitted directly between terminal equipment and telephone network via the network access line.

Abstract: A method and a device are described for providing or simulating a direct dial-in function by providing an extension dialing function in telecommunication systems that have no direct dial-in capability with dedicated extension numbers. The dial-in capability is implemented in that an incoming call is automatically received by the TC system, the user is automatically prompted, via an audio user message, to input extension dialing commands, these extension dialing commands are automatically assigned to an extension and with this assignment information an electronic forwarding signal is generated, which causes the TC system to switch the incoming connection to an extension. This forwarding signal simulates the control signal generated in manual forwarding between the extensions of the TC system. The device for performing the method is integrated as a circuit arrangement in a TC system or designed as an adaptive device retrofitted on existing TC systems.
