Chapter 1 Introduction The NexusLink 3112u Multi DSL Bonded Router is a single box solution for triple play applications. It features dual xDSL bonded ports that provide twice the xDSL bandwidth (ADSL2+ in both ATM/PTM modes and VDSL2 PTM 8a/8b/8c/8d/12a/12b/17a profiles) over comparable single-port models. With PTM mode supported, it can provide better performance than a regular ATM mode router. The NexusLink 3112u is equipped with three Fast Ethernet ports, one Gigabit port and 802.
1.1 Features • Integrated 802.11n AP (802.11b/g backward-compatible) • Configuration backup and restoration • Automatically switches to ADSL2+/VDSL2 according to the port setting of DSLAM • Up to 16 PVCs and Up to 8 PTM flows • Supports bonded xDSL lines • IPv6 compliant • VDSL2 12a/12b profile support • Printer Server (IPP) • Per-VC packet level QoS • Firmware upgrade and configuration • WPA and 802.1x • • WPS 2.
Chapter 2 Installation 2.1 Hardware Setup Follow the instructions below to complete the hardware setup. Non-stackable This device is not stackable – do not place units on top of each other, otherwise damage could occur. 2.2 Hardware Setup Follow the instructions below to complete the hardware setup. BACK PANEL The figure below shows the back panel of the device. Power Button DSL Port Ethernet (LAN) Ports Power Port Reset Button Power ON Press the power button to the OFF position (OUT).
NOTE: If pressed down for more than 60 seconds, the NexusLink 3112u will go into a firmware update state (CFE boot mode). The firmware can then be updated using an Internet browser pointed to the default IP address. GB ETH Port Use RJ45 straight through or crossover MDI/X cable to connect to Ethernet WAN. Ethernet (LAN) Ports Use 10/100 BASE-T RJ-45 cables to connect up to four network devices (as the GB ETH port can also be used).
2.3 LED Indicators The front panel LED indicators are shown below and explained in the following table. This information can be used to check the status of the device and its connections. LED Color Green Mode On The device is powered up. Off The device is powered down. On POST (Power On Self Test) failure or other malfunction. A malfunction is any error of internal sequence or state that will prevent the device from connecting to the DSLAM or passing customer data.
Flashing at 2 Hz with a 50% duty cycle when trying to detect carrier signal flashing at 4 Hz with a 50% duty cycle when the carrier has been detected and the modem is trying to train. DSL2 On The DSL2 link is established. Off The device is powered down. Blink DSL2 attempting sync: Flashing at 2 Hz with a 50% duty cycle Green when trying to detect carrier signal flashing at 4 Hz with a 50% duty cycle when the carrier has been detected and the modem is trying to train.
Chapter 3 Web User Interface This section describes how to access the device via the web user interface (WUI) using an Internet browser such as Internet Explorer (version 5.0 and later). 3.1 Default Settings The factory default settings of this device are summarized below. • • • • • • LAN IP address: 192.168.1.1 LAN subnet mask: 255.255.255.
3.2 IP Configuration DHCP MODE When the NexusLink 3112u powers up, the onboard DHCP server will switch on. Basically, 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.
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.
3.3 Login Procedure Perform the following steps to login to the web user interface. NOTE: The default settings can be found in section 3.1 Default Settings. 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.
STEP 3: After successfully logging in for the first time, you will reach this screen. You can also reach this page by clicking on the following icon located at the top of the screen.

5.2 NAT To display this option, NAT must be enabled in at least one PVC. NAT is not an available option in Bridge mode. 5.2.1 Virtual Servers Virtual Servers allow you to direct incoming traffic from the WAN side (identified by Protocol and External port) to the internal server with private IP addresses on the LAN side. The Internal port is required only if the external port needs to be converted to a different port number used by the server on the LAN side. A maximum of 32 entries can be configured.
Consult the table below for field and header descriptions. Field/Header Description Choose All Interface Virtual server rules will be created for all WAN interfaces. Choose One Interface Select a WAN interface from the drop-down box. Use Interface Select a Service Or Custom Service User should select the service from the list. Or User can enter the name of their choice. Server IP Address Enter the IP address for the server.
5.2.2 Port Triggering Some applications require that specific ports in the firewall be opened for access by the remote parties. Port Triggers dynamically 'Open Ports' in the firewall when an application on the LAN initiates a TCP/UDP connection to a remote party using the 'Triggering Ports'. The Router allows the remote party from the WAN side to establish new connections back to the application on the LAN side using the 'Open Ports'. A maximum 32 entries can be configured.
Field/Header Description Use Interface Select a WAN interface from the drop-down box. Select an Application Or Custom Application User should select the application from the list. Or User can enter the name of their choice. Trigger Port Start Enter the starting trigger port number (when you select custom application). When an application is selected, the port ranges are automatically configured. Trigger Port End Enter the ending trigger port number (when you select custom application).
5.2.3 DMZ Host The DSL router will forward IP packets from the WAN that do not belong to any of the applications configured in the Virtual Servers table to the DMZ host computer. To Activate the DMZ host, enter the DMZ host IP address and click Save/Apply. To Deactivate the DMZ host, clear the IP address field and click Save/Apply. Enable NAT Loopback allows PC on the LAN side to access servers in the LAN network via the router’s WAN IP.

Click Apply/Save to apply the selected wireless options. Consult the table below for descriptions of these options.
Option Description Hide Access Point Select Hide Access Point to protect the access point from detection by wireless active scans. To check AP status in Windows XP, open Network Connections from the start Menu and select View Available Network Connections. If the access point is hidden, it will not be listed there. To connect a client to a hidden access point, the station must add the access point manually to its wireless configuration.
5.4.2 Security The following screen appears when Wireless Security is selected. The options shown here allow you to configure security features of the wireless LAN interface. Click Apply/Save to implement new configuration settings. WIRELESS SECURITY Setup requires that the user configure these settings using the Web User Interface (see the table below). Select SSID Select the wireless network name from the drop-down box. SSID stands for Service Set Identifier.
The settings for WPA-PSK authentication are shown next. WEP Encryption This option specifies whether data sent over the network is encrypted. The same network key is used for data encryption and network authentication. Four network keys can be defined although only one can be used at any one time. Use the Current Network Key list box to select the appropriate network key. Security options include authentication and encryption services based on the wired equivalent privacy (WEP) algorithm.
hexadecimal numbers. A 128-bit key contains 13 ASCII characters or 26 hexadecimal numbers. Each key contains a 24-bit header (an initiation vector) which enables parallel decoding of multiple streams of encrypted data. Please see 6.13 for MAC Filter, Wireless Bridge and Advanced Wireless features.
