Abstract
An apparatus and method of controlling activation of electronic circuitry of data ports of a communication system is disclosed. One method includes a first data port detecting a lack of data for transmission to a second data port. At least one of the first data port and a second data port deactivate electronic circuitry of at least one of the first and second data ports upon detection of the lack of data. The first and second data ports maintain synchronization with each other while the electronic circuitry is deactivated by periodically exchanging synchronization test patterns. At least one of the first data port and the second data port transmit an alert to the other of the first and second data port when data for communication is detected. The other of the first data port and the second data port activate electronic circuitry upon receiving the alert. At least one of the first data port and the second data port transmit data.
