Controlling activation of electronic circuitry of data ports of a communication system
View Patent ↗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.
1. A method of controlling activation of electronic circuitry of data ports of a 10G Ethernet system, comprising:
at least one of the first data port and a second data port deactivating electronic circuitry of at least one of the first and second data ports;
the first and second data ports maintaining 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 transmitting 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 activating electronic circuitry upon receiving the alert;
the first data port and the second data port exchanging data;
wherein data communication between the first data port and the second data port includes a plurality wired connections connected to the first data port and the second data port, and the alert is transmitted over a subset of the plurality of wired connections,
further comprising selecting a first alert signal for a master transceiver data port, and selecting a second alert signal for a slave transceiver data port, wherein the first alert signal comprises a series of symbols, and the second alert signal comprises the series of symbols in a reverse order.
2. A data port, comprising
means for communicating with a second data port of a communication system,
means for deactivating electronic circuitry of the data port if a lack of data is detected;
means for the data port to maintain synchronization with the second data port while the electronic circuitry is deactivated by periodically exchanging synchronization test patterns;
means for the data port transmitting an alert to the second data port when data for communication is detected;
wherein data communication between the data port and the second data port includes a plurality wired connections connected to the data port and the second data port, and the alert is transmitted over a subset of the plurality of wired connections,
further comprising means for selecting a first alert signal for a master transceiver data port, and selecting a second alert signal for a slave transceiver data port, wherein the first alert signal comprises a series of symbols, and the second alert signal comprises the series of symbols in a reverse order.
3. The data port of claim 2 , further comprising:
means for designating predetermined time slots;
means for transmitting the alert during at least one of the predetermined time slots.
4. The data port of claim 3 , further comprising adaptively selecting a time period between the predetermined time slots.
5. The data port of claim 3 , further comprising adaptively selecting a time-duration of each of the predetermined time slots.
6. The data port of claim 5 , wherein the time-duration of the predetermined time slots is adaptively selected based on a desired latency of data transmission.
7. The data port of claim 2 , further comprising:
configuring the alert to comprise a high-autocorrelation signal.
8. The data port of claim 7 , wherein configuring the alert to comprise a high-autocorrelation signal comprises selecting a pre-selected signal format.
