Abstract: Coupling device (150) according to the invention for connecting a DCE to a PSTN including the electronic components matching the electric requirements of a specific PSTN. The coupling device comprises plugging means for removably connecting the latter to the DCE, means (227) for storing an identification code corresponding to a specific type of PSTN to which the coupler is intended to be connected to. The coupling device (150) further comprises means (226) responsive to a control signal received from the DCE for transmitting the identification code to the DCE. The DCE connected to the coupling device includes processing means and a storage for storing tables, each table comprising data characterizing a specific PSTN which the DCE is intended to operate with. The DCE reads the identification code during an identification phase by transmitting the control signal and selects in response to said reading the appropriate table corresponding to the coupling device. Therefore, by simply connecting an appropriate coupling device, a same DCE can be easily adapted to operate with a specific PSTN. Moreover, since the voluminous components are located into the coupling device, the DCE can be easily integrated, for example in one workstation.

Abstract: Coupling device for the connection of a Data Circuit Terminating Equipment DCE to a given Public Switched Telephone Network PSTN and to a local telephone set. The coupler includes means for providing said local telephone set with DC current whereby the microphone and the headphone of the telephone can be used respectively for transmitting and receiving vocal messages from the a DTE which is connected to said DCE. The invention also provides a DCE for the connection of a DTE toga a PSTN and to a local telephone set including a coupler circuit having the electronic components matching the electric requirements of a given PSTN. The coupler further includes means for providing the telephone set with DC current whereby vocal messages can be transmitted and received from the DTE to the telephone set. The invention further provides a DCE for the connection of a DTE to a PSTN and to a local telephone set which includes means for removably attaching a coupler circuit having the electronic components matching the electrical requirements of a given PSTN and further including means for providing the telephone set with DC current whereby vocal messages can be transmitted and received from the telephone set to the DTE.
