Claim 14:
15. A customer premises equipment apparatus comprising:
at least one processor; and
at least one memory including computer program code;
the at least one memory and the computer program code configured to, with the at least one processor, cause the customer premises equipment apparatus at least to perform:
operate in a full duplex, FDX, mode when receiving and/or transmitting signals over a first set of communication lines or operate in a Time Division Duplex, TDD, mode when receiving or transmitting signals from a second set of communication lines; with symbols of the FDX mode having a first structure and symbols of the TDD mode having a second structure,
receive instructions from a communication controller for controlling operation of said customer premises equipment apparatus, such that,
when operating in the full duplex, FDX, mode, transmitting an upstream symbol with the first structure at a reference time point trf, and
when operating in the Time Division Duplex, TDD, mode, transmitting an upstream symbol with the second structure at tTDD_US_TX=trf−tPD2 during a time interval assigned for upstream transmission on the second communication line, wherein tPD2 is a propagation delay in said second mode and received from said communication controller.
