Duplex Mode

AT-FS705E FC and AT-FS706E FC Installation Guide

How a switch signals an end node to stop transmitting data differs depending on the speed of the end node and switch port. Ports operating at 10 Mbps use flow control while ports operating at 100 Mbps use backpressure.

For a 10 Mbps port, the switch will stop an end node from transmitting data by forcing a collision. A collision on an Ethernet network occurs when two nodes attempt to transmit data using the same data link at the same time. A collision causes end nodes to stop sending data. When the switch needs to stop a 10 Mbps end node from transmitting data, it forces a collision on the data link, which stops the end node. Once the switch is ready to receive data again, the switch stops forcing collisions.

A port running at 100 Mbps uses PAUSE frames, as specified in the IEEE 802.3x standard. Whenever the switch wants an end node running at 100 Mbps to stop transmitting data, it issues a PAUSE frame. The frame simply instructs the end node to cease transmission. The switch continues to issue PAUSE frames until it is ready to again receive data from the end node.

Duplex mode refers to the manner in which an end node handles the receiving and transmitting of data. If an end node can receive or transmit data, but not both at the same time, the end node is operating in what is referred to as half- duplex mode. If an end node can both receive and transmit data simultaneously, the node is operating in full-duplex mode. Naturally, a node capable of operating in full-duplex can handle data much faster than a node that can only operate in half-duplex.

Each port on an AT-FS705E FC Series switch and AT-FS706E FC Series switch can operate in either half- or full-duplex mode. The twisted pair ports are IEEE 802.3u-compliant and will auto-negotiate the duplex mode setting. If the end node connected to a twisted pair port on the switch is capable of full- duplex operation, the switch sets the twisted pair port to full-duplex. If the end node is capable of only half-duplex, the port is set automatically to half- duplex.

The duplex mode for the fiber optic port(s) must be set manually using the 100FX DUPLEX switch on the front panel of the switch. For the fiber optic port to function correctly, this switch must be set to correspond to the duplex mode capability of the end node connected to port.
