Twisted Pair Port

The 1000Base-T port on the AT-PB1005G media converter has an RJ-45

connector and is designed to operate with Category 5 or better shielded

or unshielded twisted pair cable.

An RJ-45 twisted pair port on a 1000 Mbps Ethernet network device can

have one of two possible wiring configurations: MDI or MDI-X. The RJ-45

port on a PC, router, or bridge is typically wired as MDI, while the twisted

pair port on a switch or hub is usually MDI-X.

To connect two network devices that have dissimilar wiring

configurations, such as MDI to MDI-X, you use a straight-through twisted

pair cable. To connect two network devices that have the same wiring

configuration, such as MDI to MDI, you use a crossover cable.

The AT-PB1005G media converter features automatic MDI/MDI-X. Each

port automatically determines the configuration of the port on the

device to which it is connected and then configures itself appropriately.

For example, if a port on a media converter is connected to a port on a

bridge, which is typically wired as MDI, the port on the media converter

automatically configures itself as MDI-X. This feature allows you to use

either straight-through or crossover cables when connecting devices to

the media converter. This eliminates the need for a cross-over cable.
