A network switch displays a state signal of network connection ports by a combination of LEDs and includes a signal management unit, a control unit, switch members, and the LEDs. The signal management unit receives the state signal from the network connection ports and transmits data to the control unit to control each of the switch members and correspondingly output to control each of the LEDs. The state signal includes that a first state data outputs an active/inactive state via a first control signal, a second state data and a third state data output a link-down/up state and a connection speed state via a second control signal, so that the LEDs displays different states of the network connection ports based on a combination of each of the first control signal and each of the second control signal.

A method of data processing is applied to a communications device including a first sublayer. A physical sublayer is added above a physical coding sublayer (PCS) of a physical layer, and the physical sublayer is connected to media independent interfaces (xMIIs) with different Ethernet rates. Data signals from different media access control clients (MAC) are interleaved using the physical sublayer. Then, a tx_cmd command is used to instruct the PCS to correspondingly encode an xMII signal. Finally, an encoded xMII signal is sent through a port. According to this method, an encoding function of the PCS may continue to be used, to decouple interleaving from encoding and perform the interleaving through an xMII interface. In this case, port channelization can be implemented for ports with multiple rates, and transmission of a high-priority service is ensured when there is an excessively large quantity of service flows in a transmission process.

A tower-mounted networking device facilitates deploying a remote station without having to build a custom station aside a radio tower. The networking device's chassis comprises a mounting bracket, which includes a curved contour for mounting the networking device on the radio tower. Also, the chassis can be resistant to weather intrusion, by not including a vent, to allow the networking device to be installed outdoors. The networking device can include a first power port coupled to an external connection line from a source external to the tower, such that the external connection line provides at least power to the networking device. The networking device can use the power to power a set of antenna mounted on the radio tower. The networking device can also relay a network connection between a pair of antennas, and/or between an antenna and a network connection to an Internet service provider.
