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.
Table 2-2 lists the router models described in this guide and summarizes the LAN interfaces supported
on each model.
Token Ring Connections
The Cisco 2612 router provides both an Ethernet interface and a Token Ring shielded UTP interface.
The Cisco 2613 router provides a single Token Ring interface. (See Table 2-2.)
The IEEE has established Token Ring as standard IEEE 802.5. Specifications indicate a maximum
segment distance of 328 feet (100 meters) for UTP cabling.
