Page 7: Chapter 1 Introduction
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. -

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. - Page 15 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).
