Ethernet Connections - Cisco Network Device 2800 Introduction Manual

Ethernet Connections

The IEEE has established Ethernet as standard IEEE 802.3. Cisco 2800 series routers support the
following Ethernet implementations:
•
•
•
Refer to the
Ethernet cables, connectors, and pinouts.
Serial Connections
Serial connections are provided by WAN interface cards and network modules. For more information on
WAN interface cards, refer to the
network modules, refer to the

Before you connect a device to a serial port, you need to know the following:

Configuring Serial Connections
The serial ports on the asynchronous/synchronous serial network modules and the serial WAN interface
card use DB-60 connectors. Serial ports can be configured as DTE or DCE, depending on the serial cable
used.
Serial DTE or DCE Devices
A device that communicates over a synchronous serial interface is either a DTE or DCE device. A DCE
device provides a clock signal that paces the communications between the device and the router. A DTE
device does not provide a clock signal. DTE devices usually connect to DCE devices. The documentation
that accompanied the device should indicate whether it is a DTE or DCE device. (Some devices have a
jumper to select either DTE or DCE mode.)

1000BASE-T—1000 Mbps full-duplex transmission over a Category 5 or better unshielded
twisted-pair (UTP) cable. Supports the Ethernet maximum length of 328 feet (100 meters).
The Cisco 2801 and Cisco 2811 routers do not support the 1000BASE-T Ethernet

implementation.
100BASE-T—100 Mbps full-duplex transmission over a Category 5 or better unshielded
twisted-pair (UTP) cable. Supports the Ethernet maximum length of 328 feet (100 meters).
10BASE-T—10 Mbps full-duplex transmission over a Category 5 or better unshielded twisted-pair
(UTP) cable. Supports the Ethernet maximum length of 328 feet (100 meters).
