3.2 IP C onfiguration
DHCP MODE
When the CT-5364A powers up, the onboard DHCP server will switch on.
The DHCP server issues and reserves IP addresses for LAN devices, such as your PC.
To obtain an IP address from the DCHP server, follow the steps provided below.
NOTE: The following procedure assumes you are running Windows XP.
However, the general steps involved are similar for most operating
systems (OS). Check your OS support documentation for further details.
STEP 1: From the Network Connections window, open Local Area Connection (You
may also access this screen by double-clicking the Local Area Connection
icon on your taskbar). Click the Properties button.
STEP 2: Select Internet Protocol (TCP/IP) and click the Properties button.
STEP 3: Select Obtain an IP address automatically as shown below.
STEP 4: Click OK to submit these settings.
If you experience difficulty with DHCP mode, you can try static IP mode instead, as
described on the next page.

13
STATIC IP MODE
In static IP mode, you assign IP settings to your PC manually.
Follow these steps to configure your PC IP address to use subnet 192.168.1.x.
NOTE: The following procedure assumes you are running Windows XP.
However, the general steps involved are similar for most operating
systems (OS). Check your OS support documentation for further details.
STEP 1: From the Network Connections window, open Local Area Connection (You
may also access this screen by double-clicking the Local Area Connection
icon on your taskbar). Click the Properties button.
STEP 2: Select Internet Protocol (TCP/IP) and click the Properties button.
STEP 3: Change the IP address to the domain of 192.168.1.x (1<x<255) with
subnet mask of 255.255.255.0. The screen should now display as below.
STEP 4: Click OK to submit these settings.

14
3.3 Login P rocedure
Perform the following steps to login to the web user interface.
NOTE: The default settings can be found in section 3.1.
STEP 1: Start the Internet browser and enter the default IP address for the device
in the Web address field. For example, if the default IP address is
192.168.1.1, type http://192.168.1.1.
NOTE: For local administration (i.e. LAN access), the PC running the browser
must be attached to the Ethernet, and not necessarily to the device. For
remote access (i.e. WAN), use the IP address shown on the Device
Information screen and login with remote username and password.
STEP 2: A dialog box will appear, such as the one below. Enter the default
username and password, as defined in section 3.1 Default Settings.
Click OK to continue.

Chapter 4 Quick Setup
After login, the Quick Setup screen will appear as shown.
NOTE: The selections available on the main menu are based upon the configured
connection type and user account privileges.
The Quick Setup screen allows the user to configure the CT-5364A for ADSL
connectivity and Internet access. It also guides the user though the WAN network
setup first and then the LAN interface setup. You can either do this manually or
follow the auto quick setup (i.e. DSL Auto-connect) instructions.
This router supports the following data encapsulation methods.
•PPP over Ethernet (PPPoE)
•PPP over ATM (PPPoA)
•MAC Encapsulated Routing (MER)
•IP over ATM (IPoA)
•Bridging
The following configuration considerations apply:
•The WAN network operating mode operation depends on the service provider’s
configuration in the Central Office and Broadband Access Server for the PVC
•If the service provider provides PPPoE service, then the connection selection
depends on whether the LAN-side device (typically a PC) is running a PPPoE
client or whether the router is to run the PPPoE client. T he router can support
both cases simultaneously.
•If none of the LAN-side devices run PPPoE clients, then select PPPoE.
•NAT and firewall can be enabled or disabled by the user in router modes (PPPoE,
PPPoA, MER or IPoA) and they are always disabled with Bridge mode.
•Depending on the network operating mode, and whether NAT and firewall are
enabled or disabled, the main menu will display or hide NAT and Firewall.

17
NOTE: Up to sixteen PVC profiles can be configured and saved on the flash
memory. To activate a particular PVC profile, you need to navigate all the
Quick Setup pages until the last summary page, then click on the Finish
button and reboot the system.
4.1 Auto Quick Setup
The auto quick setup requires the ADSL link to be up. The ADSL router will
automatically detect the PVC, so just follow the easy online instructions.
STEP 1: Select Quick Setup to display this screen.
STEP 2: Click Next to start the setup process. Follow the online instructions to
complete the settings. This procedure will skip some processes such as
the PVC index and encapsulation mode selection.
