Claim 4:
5. The method of claim 4, further comprising:
determining a first propagation delay tPD1 over the first communication line;
determining a second time gap tg2_TDD to be applied at the access node separating an end of a downstream sub-frame transmitted onto the second communication line and a beginning of a subsequent upstream sub-frame received from the second communication line;
determining a second propagation delay tPD2 over the second communication line;
controlling a transmission of an upstream TDD sub-frame by the second remote communication unit and a transmission of a second FDX sub-frame by the access node such that the upstream TDD sub-frame is transmitted before the transmission of the second FDX sub-frame by an amount of time equal to the second propagation delay tPD2; and
determining said first time gap tg1′_FDX as tg1′_FDX=tg2_TDD-tPD1.
