Abstract:
1. A method for establishing a connection between a virtual electronic teaching system having a central content-server for an e-learning or tele-teaching event and a workstation of a person participating in the e-learning or tele-teaching event utilizing a telecommunication network having a main distribution connected to an exchange with an access multiplexer and a splitter or a splitter connected to or integrated in the main distribution and an analog or digital telecommunication device, the method comprising: connecting an interface circuit to the telecommunication device or to the workstation, the interface circuit including a memory unit and a microprocessor; registering the interface circuit to the content-server by means of a log-in procedure stored in the memory unit, the interface circuit registering vicariously for the telecommunications device; establishing a connection between the interface circuit and the content-server vicarious for the telecommunication device connected to said main distribution via a subscriber line or subscriber modem and splitter or a network termination and subscriber lines; determining a type of connection pending on the communications interface of the interface circuit; transmitting at least one stored test signal from the memory unit of the interface circuit to the content-server; evaluating an acknowledgement received by the interface circuit from the content-server in response to the test signal; testing at least a bandwidth available to the telecommunication device using the interface circuit, testing all available protocols in communication with said content-server using the interface circuit as the content-server adjusts itself, adjusting the interface circuit to a protocol proposed by the content-server, and preventing “time out”-problems by emitting a message from the interface circuit confirming the complete reception of an image file from the content-server such that said workstation remains connected to said e-learning or tele-teaching event including during periods when broadband transmission is not possible.
