Network Cabling Specifications

See the following document for more information about network connections and interfaces:

•Cisco Modular Access Router Cable Specifications

Warning To avoid electric shock, do not connect safety extra-low voltage (SELV) circuits to telephone-network voltage (TNV) circuits. LAN ports contain SELV circuits, and WAN ports contain TNV circuits. Some LAN and WAN ports both use RJ-45 connectors. Statement 1021

Ethernet Connections

The IEEE has established Ethernet as standard IEEE 802.3. The Cisco CGR 2010 router supports the following Ethernet implementations:

•1000BASE-X—1000 Mb/s full-duplex transmission over a Category 5 or better unshielded twisted-pair (UTP) cable (IEEE 802.3z). Supports the Ethernet maximum length of 328 feet (100 meters).

•1000BASE-T—1000 Mb/s full-duplex transmission over a Category 5 or better unshielded twisted-pair (UTP) cable (IEEE 802.3ab). Supports the Ethernet maximum length of 328 feet (100 meters).

•100BASE-TX—100 Mb/s full-duplex transmission over a Category 5 or better unshielded twisted-pair (UTP) cable (IEEE 802.3u). Supports the Ethernet maximum length of 328 feet (100 meters).

See Cisco Modular Access Router Cable Specifications at www.cisco.com for information about Ethernet cables, connectors, and pinouts.

Serial Connections

Serial connections are provided by the grid router WAN interface card (GRWIC). Before you connect a device to a serial port, you need to know the following:

•Type of device, data terminal equipment (DTE) or data communications equipment (DCE), you are connecting to the synchronous serial interface

•Type of connector, male or female, required to connect to the device

•Signaling standard required by the device

Configuring Serial Connections

The serial ports on the asynchronous/synchronous serial network modules and the serial grid router WAN interface card use a GRWIC-8A/S cable with a DB-25 connector. 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 DCE or DTE 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.) Table 2-1lists typical DTE and DCE devices.
