Abstract:
A method for adapting a supplementary equipment to an analog telecommunications terminal equipment, the supplementary equipment including at least one of an automatic answering equipment, an intercommunication station, and an automatic dialer, and the analog telecommunications terminal equipment including a hybrid circuit arranged with respect to a network access line for connection to a telephone network and through which voice signals and signaling signals are capable of being transmitted, comprising the steps of:providing a high-resistance access to the network access line while maintaining a line termination resistance for detecting the voice signals transmitted to the analog telecommunications terminal equipment; supplying one of a picked-off speech signal and a speech signal proportional to the picked-off speech signal to the supplementary equipment and to a voice input/output unit that is electrically separate from the analog telecommunications terminal equipment; causing at least one of the supplementary equipment and the voice input/output unit to generate an output signal; providing a high-resistance feeding of the output signal into the network access line while maintaining the line termination resistance; and causing a direct transmission of the signaling signals between the analog telecommunications terminal equipment and the telephone network via the network access line.
