Unit 3 Graded Practice 1:  Adding a DSLAM
A DSLAM (Digital Subscriber Line Access Multiplexer) is a network device that receives signals from multiple customer Digital Subscriber Line (DSL) connections and puts them onto a single Ethernet connection. In this graded practice you will add a DSLAM which will allow DSL customers to connect to your network.
DSLAM in Packet Tracer
The DSLAM in packet tracer is found in network devices on the far right side.  Click on the cloud and then select PT-Empty from the right side and drag it to your desktop.
Click on the cloud and turn the power off (you may need to scroll to the right).  Fill the DSLAM with nine PT-CLOUD-NM-1AM are cards placed in all slots except the bottom left.  In the bottom left add a PT-CLOUD-NM-1CGE card.  This will give you 9 DSL connections for customers and a Gigabit Ethernet port to connect your DSLAM to the network.
Now turn the power back on.  Take a screenshot of your DSLAM.
Programming your DSLAM
In order for the DSLAM to transfer traffic from the DSL modem to the Ethernet port you must program the DSLAM.  Open the config tab and go to the DSL item under the Connections list.
On the right you will see your DSL to Ethernet connections.  Click the Add button.  You will see this will add the connection from Modem0 to the Ethernet port on the DSLAM.
Select from the drop down menu on the left Modem1 and click add.  This will add the second connection from Modem1 to the Ethernet port.
Continue adding ports until all modems have been added to the list.  Your DSLAM is now ready to add to your network.
Add a router
Add a 1941 router to your network and connect from your DSLAM to the G0/0 port on your router using a straight through copper cable.
Go to your router and programming as follows
Router> enable
Router# configure terminal
Router(config)# hostname R1
R1(config)# interface G0/0
R1(config-if)# ip address 10.___.1.1
R1(config-if)# no shutdown
Program a DHCP pool onto your router
R1(config)#ip dhcp pool mypool
R1(dhcp-config)#network 10.___.1.0
R1(dhcp-config)#default-router 10.___.1.1
Add a DSL modem from the WAN emulation tab
Connect from your DSL modems to the DSLAM using a phone cable and connect a computer to your DSL modem using an Ethernet cable.
Go to your PC and pull an IP address from your network.  To do this all you need to do is go to the Desktop tab of the PC and select DCHP under IP Configuration.
Take a screenshot.
