Connecting the Router to the ADSL Line
This section describes how to connect the Cisco 1400 series router to the ADSL line.
Follow the steps for the router model that you are using.
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. Use
caution when connecting cables.
Warning Hazardous network voltages are present in WAN ports regardless of whether
power to the router is OFF or ON. To avoid electric shock, use caution when working near
WAN ports. When detaching cables, detach the end away from the router first.
Cisco 1401 Router
Follow these steps, and refer to Figure 2-6 to connect the Cisco 1401 router to the ADSL
line:
Step 1 Connect one end of the green cable to the green ATM-25 port on the router.
Step 2 Connect the other end of the green cable to the appropriate port on the DSL
modem. On the Cisco 625 modem (shown in Figure 2-6), this is the port labeled
DATA.
Caution Always connect the green ATM cable to the green ATM port. Do not connect the
cable to the Ethernet port or to the console port. This will damage your router.
