Abstract

The invention provides a technique for power cutback of DSL transceivers (e.g., modems) using public switched telephone network (PSTN) signaling. For example, one or more dual-tone/multiple frequency (DTMF) signals generated by a touch-tone telephone, or other device, can cause a DSL transceiver to reduce the power of upstream data communications. A user of a DSL modem can cause th emodem to transmit upstream data while listening to the microphone of a telephone coupled to the same twisted-pair line. Data transmission power can be adjusted by use of one or more buttons on the telephone. The DSL
transceiver, in response to one or more predeteremined DTMF signals, can adjust transmission power. Thus, the poer cutback of the DSL transceiver can be controlled using PSTN signaling.
