Abstract:
1. Telecommunication system for bidirectional transmission of data and voice signals to at least one customer building, the system comprising: a) a data network, which is connected via a satellite data transmission link for bidirectional data signal transmission to at least one local satellite device, provided in at least one customer building, the local satellite device being connected to a 10 Base S switching device via a local broadband data network cable; b) a public telephone network, which is connected via a number of subscriber telephone lines for bidirectional voice signal transmission to the 10 Base S switching device; and c) a number of 10 Base S subscriber modems, which are connected via local telephone lines for bidirectional voice and data signal transmission to the 10 Base S switching device; d) wherein the data transmission link has at least one satellite as a relay station for relaying data between the at least one local satellite device and a central satellite device connected via a gateway to the data network; e) wherein downstream data is transmitted from the local satellite device via the local broadband data network cable and the 10 Base S switching device to the 10 Base S subscriber modems over the local telephone lines in a first freguency band; f) wherein upstream data is transmitted from the 10 Base S subscriber modems over the local telephone lines in a second frequency band to the 10 Base S switching device and via the local broadband data network cable to the local satellite device; and g) wherein the voice signals are transmitted over the local telephone lines in a third freguency band.
