The invention relates to a bundling unit (BU) for facilitating communication between a plurality of clients (CL1, CL2, CL3, CL4) and a DSLAM (10) in a DSL network to transmit at least one signal from the DSLAM (10) to at least one client (CL1, CL2, CL3, CL4) upon request. The bundling unit (BU) is arranged to communicate with the DSLAM (10) via a first set of lines (L1, L2, L3, L4) and with the clients (CL1, CL2, CL3, CL4) via a second set of lines (L1', L2', L3', L4'). The bundling unit (BU) is arranged to
a) receive a request for a signal from a client (100);
b) verify if the requested signal is already available at the bundling unit (BU) (102) and
b1) if so, forward the requested signal to the client (103), and
b2) if not, select one of the available lines (L1, L2, L3, L4) to forward the request to the DSLAM (10) (106).
