6. Positioning Ethernet in the Campus Access Layer Distribution Layer Core Layer Ethernet 10BaseT Position Fast Ethernet Position Access Layer Distribution Layer Core Layer Provides connectivity between the end-user device and the access switch. Not typically used at this layer. Gives high-performance PC and workstations 100-Mbps access to the server. Provides connectivity between access and distribution layers. Provides connectivity from the distribution to core layer. Provides connectivity from the server block to the core layer. Provides inter-switch connectivity. Not typically used at this layer.

21. Cabling Routers for ISDN Connections (cont.) !!!WARNING!!! Do not connect a cable to an ISDN port unless it is from an ISDN switch or ISDN wall jack. If you connect a cable from any other device to the BRI port, you will ruin the non-ISDN device. Cisco Router ISDN BRI Port
Purpose: This chapter reviews the physical layer and describes how to cable various network devices. Timing: This chapter takes approximately 1 hour to present. Note: This chapter has a cabling laboratory exercise at the end. Contents: Objectives—This section explains what the student will be able to do at the end of this chapter. Cabling the LAN—This section describes available Ethernet connections. Cabling the WAN—This section describes the cabling of serial and ISDN BRI connections. Setting Up Console Connections to Cisco Devices—This section describes how to cable a console connection. Laboratory Exercise—This section provides a laboratory exercise in which students cable the lab. Summary—This section summarizes what was taught in this chapter. Review Questions—This section offers open-ended review questions. They should foster discussion after presenting the chapter. Transition: Following are the list of performance objectives that describe what students will be able to do at the end of the chapter.
