Patent ID: 7020101

Claim:
A method of implementing a repeater in a data transmission system in which, to transmit data on a data transmission connection, at least two different frequency bands are allocated for both directions of transmission, whereby a transceiver unit of the data transmission system comprises a first and a second transceiver block which can function in parallel with each other such that they transmit and receive information on different frequency bands with the same part of the data transmission connection, the method comprising: connecting said transceiver blocks of the transceiver unit in series by connecting the receiver output of the first block to the transmitter input of the second block and the receiver output of the second block to the transmitter input of the first block, and connecting the transceiver unit between two parts of the data transmission connection by connecting the receiver input and transmitter output of the first transceiver block to the first part of the data transmission connection and the receiver input and transmitter output of the second transceiver block to the second part of the data transmission connection, whereby the transceiver unit acts as a repeater between the first and second part of the data transmission connection.
