Abstract:
1. A Digital Subscriber Line (DSL) transceiver device, comprising a modem comprising a transmit data input, a receive data output and an external interface to couple the DSL transceiver device to a first subscriber device via a first cable; and a transmit power spectrum adjuster comprising an input coupled to the receive data output and an output coupled to the transmit data input, wherein the transmit power spectrum adjuster is configured to, in response to receiving an attenuation measure from the receive data output, determine a modified attenuation measure based on the attenuation measure and information indicating a length of a part of a second cable, the second cable connecting a further DSL transceiver device and a second subscriber device, wherein the part of the second cable extends from the further DSL transceiver device to a point of the second cable from where the first cable joins the second cable to extend to the first subscriber device, the transmit power spectrum adjuster configured to provide the modified attenuation measure to the output coupled to the transmit data input of the modem.
