Preparing to Install the Router
Token Ring Connections
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.
Note
To ensure agency compliance with FCC Class B electromagnetic emissions requirements (EMI), make
sure that you use a shielded RJ-45 Token Ring cable when connecting your router to a Token Ring
network.
Token Ring can operate at two different ring speeds: 4 and 16 Mbps. All devices on the Token Ring must
use the same operating speed.
Use a Token Ring cable to connect the router to a switch. Refer to the section "Token Ring Port Pinouts"
in the
pinouts. This document is available online and on the Cisco Documentation CD-ROM.
Serial Connections
Serial connections are provided by WAN interface cards and network modules. For more information on
WAN interface cards, refer to the

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.)
