Abstract
The access node includes first transmit/receive circuitry with digital signal processing logic and digital-to-analog/analog-to-digital conversion logic, and second transmit/receive circuitry with transmit/receive amplifiers and line adaptation units for connection to a transmission line. The access node further includes an analog switch for dynamically connecting one of the first transmit/receive circuitry with one of the second transmit/receive circuitry according to a transmit/receive cross-connect table, and transmit/receive control logic for updating the transmit cross-connect table according to a transmit/receive traffic pattern over the respective transmission lines.
