Abstract:
1. A method for operating plurality of DSL (Digital Subscriber Line) modem transmitters integrated within a circuit card, the method comprising: each DSL modem transmitter generating a full power physical frame when the DSL modem transmitter is provided with data to transmit, the full power physical frame including a control channel signal component and a data signal component; each DSL modem transmitter generating a low power physical frame having a control channel signal component and no data; each DSL modem transmitter selecting between the full power physical frame and the low power physical frame for transmission from the DSL modem transmitter, wherein selection of the low power physical frame for transmission from the DSL modem transmitter is based only on the DSL modem transmitter having no data to transmit; and limiting aggregate flow of data to the plurality of DSL modem transmitters such that a total power required by the plurality of DSL modem transmitters is held below a predefined target power level.
