Preparing to Connect to a Network

Preparing to Connect to a Network

When setting up your router, consider distance limitations and potential electromagnetic interference (EMI) as defined by the applicable local and international regulations.

Network connection considerations are provided for several types of network interfaces and are described in the following sections:

•Ethernet Connections, page 2-10

•Token Ring Connections, page 2-11

•Serial Connections, page 2-11

•ISDN BRI Connections, page 2-13

•56-K/Switched-56-kbps DSU/CSU Connections, page 2-14

Refer to the following online documents for more information about network connections and interfaces:

•Cisco Network Modules Hardware Installation Guide

•Cisco Interface Cards Installation Guide

•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 most common Ethernet implementations are as follows:

•100BASE-T—2-pair Category 5 or unshielded twisted-pair (UTP) straight-through RJ-45 cable.

•10BASE-2—Ethernet on thin coaxial cable, also known as thin Ethernet. The maximum segment distance is 607 feet (186 meters).

•10BASE-5—Ethernet on thick coaxial cable, also known as thick Ethernet. The maximum segment distance is 1,640 feet (500 meters).

•10BASE-T—Ethernet on unshielded twisted-pair (UTP) cable. The maximum segment distance is 328 feet (100 meters). UTP cables look like the wiring used for ordinary telephones; however, UTP cables meet certain electrical standards that telephone cables do not meet.

Refer to the Cisco Modular Access Router Cable Specifications online document for information about Ethernet cables, connectors, and pinouts. This document is available online and on the Cisco Documentation CD-ROM.
