Chapter 1 Introduction The CT-5071 is a wired Local Area Network ADSL2+ router. One 10/100 Base-T Ethernet port provides wired LAN. The CT-5071 ADSL router provides state of the art security features such as Firewall and VPN pass through. The CT-5071 is designed for residential applications that require wired connectivity to an ADSL broadband network. The CT-5071 supports up to 4 contiguous virtual connections allowing for multiple simultaneous Internet connections. 1.
1.2 Application The following diagram depicts the application of the CT-5071.

Chapter 2 2.1 Installation Hardware Installation In the rear panel, there is a reset button. It is used to load the factory default settings. Hold down the button until the LED’s start blinking simultaneously (about 5 seconds). After the device has booted successfully, the factory default settings are retrieved. Power Switch Reset button Follow the instructions below to complete the hardware connections.
and telephone lines from the wall outlet. Chapter 3 Login via the Web Browser This section describes how to manage the router via a Web browser via the remote end. You can use a web browser such as Microsoft Internet Explorer, or Netscape Navigator. (The Web page is best viewed with Microsoft Internet Explorer 5.0 and later): A unique default user account is assigned with user name root and password 12345. The user can change the default password later when logged in to the device. 3.
3.2 Login Procedure Perform the following steps to bring up the Web user interface and configure the CT5071. To log on to the system from the Web browser, follow the steps below: STEP 1: Start your Internet browser. Type the IP address for the router in the Web address field. For example, if the IP address is 192.168.1.1, type http://192.168.1.1 STEP 2: You will be prompted to enter your user name and password. Type root in the user name and 12345 in the password field, and click OK.
3.2.1 Default Settings During power on initialization, the CT-5071 initializes all configuration attributes to default values. It will then read the configuration profile from the Permanent Storage section on the flash memory. The default attributes are overridden when identical attributes with different values are configured. The configuration profile in Permanent Storage can be created via the Web user interface or telnet user interface, or other management protocols.
Chapter 4 Quick Setup The Quick Setup allows the user to configure the ADSL router for DSL connectivity and Internet access. It also guides the user though the WAN network setup first and then the LAN interface setup. You can either manually customize the router or follow the online instruction to set up the router. The CT-5071 ADSL router supports the following five network operating modes over an ATM PVC WAN interface.
4.1 Auto Quick Setup The auto quick setup requires the ADSL link to be up. The ADSL router will automatically detect the PVC. You only need to follow the online instructions that you are prompted. 1. Select Quick Setup to display the DSL Quick Setup screen. 2. Click Next to start the setup process. Follow the online instructions to complete the setting. This procedure will skip some processes like PVC index, or encapsulation. 3. After the settings are complete, you can use the ADSL service. 4.
STEP 2: Enter the Virtual Path Identifier (VPI) and Virtual Channel Identifier (VCI). Select Enable Quality Of Service if required. Click Next. STEP 3: Then, choose the Encapsulation mode. STEP 4: Click Next to display the following screen. Choosing different connection types pops up different settings requests. Enter appropriate settings that are requested by your service provider. The following descriptions state each connection type setup separately.
PPP over ATM (PPPoA) and PPP over Ethernet (PPPoE) 1. Select the PPP over ATM (PPPoA) or PPP over Ethernet (PPPoE) radio button and click Next. The following screen appears: PPP USERNAME/PPP PASSWORD The PPP Username and the PPP password requirement are dependent on the particular requirements of the ISP or the ADSL service provider. The WEB user interface allows a maximum of 256 characters in the PPP user name and a maximum of 32 characters in PPP password.
Disconnect if no activity The CT-5071 can be configured to disconnect if there is no activity for a period of time by selecting the Disconnect if no activity check box. When the checkbox is ticked, you need to enter the inactivity timeout period. The timeout period ranges from 1 minute to 4320 minutes. PPP IP Extension The PPP IP Extension is a special feature deployed by some service providers. Unless your service provider specially requires this setup, do not select it.
3. After entering your settings, select Next. The following screen appears. This page allows the user to configure the LAN interface IP address, subnet mask and DHCP server. If the user would like this ADSL router to assign dynamic IP address, DNS server and default gateways to other LAN devices, select the button Enable DHCP server on the LAN to enter the starting IP address and end IP address and DHCP leased time. 4.
5. After clicking Save/Reboot, the router will save the configuration to the flash memory, and reboot. The Web UI will not respond until the system is brought up again. After the system is up, the Web UI will refresh to the Device Info page automatically. The CT-5071 is ready for operation and the LEDs display as described in the LED description tables.

Enter the PVC Index provided by the ISP and click Next and click Next Select the MAC Encapsulation Routing (MER) radio button, and click Next. The following screen appears. Enter information provided to you by your ISP to configure the WAN IP settings. Notice: DHCP can be enabled for PVC in MER mode if Obtain an IP address automatically is chosen.
4. Click Next to display the following screen appears. Enable NAT checkbox: If the LAN is configured with a private IP address, the user should select this checkbox. The NAT submenu on the left side main panel will be displayed after reboot. The user can then configure NAT-related features after the system comes up. If a private IP address is not used on the LAN side, this checkbox should be de-selected to free up system resources for better performance.
5. Upon completion, click Next. The following screen appears. The Device Setup page allows the user to configure the LAN interface IP address and DHCP server. If the user would like this ADSL router to assign dynamic IP addresses, DNS server and default gateway to other LAN devices, select the radio box Enable DHCP server on the LAN to enter the starting IP address and end IP address and DHCP lease time.
After clicking Save/Reboot, the router will save the configuration to the flash memory, and reboot. The Web UI will not respond until the system is brought up again.
