Introduction Congratulations on your purchase of the NetComm NB100 Internal ADSL Modem. Follow the steps in the Quick Start Guide to begin to enjoy the benefits of a super-fast, ‘zerofootprint’ ADSL connection from your desktop. What’s in the box � NetComm NB100 PCI ADSL Card Modem � Telephone Cable � Quick Start Guide � CD-ROM with Windows driver and additional documentation Minimum System Requirements Minimum system requirements for the NetComm NB100 are: � Microsoft Windows-based PC with Pentium IV 2.
Installing your Modem Step 1 – Install the NB100 in your Computer To install the NetComm NB100, you need to know how to remove the external case from your computer and insert a PCI card. If you are unsure how to do this, consult your computer’s documentation. 1. Ensure your computer is shut down with power off and power cable unplugged. 2. Take the cover off the CPU (central processing unit) and carefully insert the NB100 into an available PCI slot. Ensure the .’golden edge’.
Do you need a Line Filter or Splitter? Micro-filters are used to prevent common telephone equipment, such as phones, answering machines and fax machines, from interfering with your ADSL service (and visca versa). If your ADSL-enabled phone line is sharing a line with any other equipment then you will need to use one micro-filter for each connected device. Alternatively, ADSL Splitters may be installed with an ADSL line installation.
NB100 Modem Analyzer Utility After the system has re-booted, you will notice that you have a desktop icon ‘ADSL Modem Analyzer’ and an icon in the task bar. NOTE: Windows XP Service Pack 2 will display a second System Tray networking icon after restart. To disable this icon, double-click on it, then click on Properties, then uncheck the box adjacent to ‘notify me when this connection has limited or no connectivity.

Appendix A: Cable Information This cable information is provided for your reference only. Please ensure you only connect the appropriate cable into the correct socket on either this product or your computer. If you are unsure about which cable to use or which socket to connect it to, please refer to the hardware installation section in this manual. If you are still not sure about cable connections, please contact a professional computer technician or NetComm for further advice.
Straight and crossover cable configuration There are two types of the wiring: Straight-Through Cables and Crossover Cables. Category 5 UTP/ STP cable has eight wires inside the sheath. The wires form four pairs. Straight-Through Cables has same pinouts at both ends while Crossover Cables has a different pin arrangement at each end. In a straight-through cable, wires 1,2,3,4,5,6,7 and 8 at one end of the cable are still wires 1~8 at the other end.
Appendix B: Glossary ASCII: American Standard Code for Information Interchange. Bandwidth: The range of frequencies of a transmission channel. The wider the range the higher the data rate that can be sent. Hence, bandwidth is also taken to mean the data rate. Baud: One baud is one symbol (state-transition or level-transition) per second. Bit: A binary digit, with the value of –0 or –1. Boot: Start a device. Bps: Bits per second. The speed at which bits are transmitted across a data connection.
ETSI: European Telecommunications Standards Institute. Firmware: Software that has been temporarily or permanently loaded into ROM. Flash memory: A type of RAM that retains its information, even after poweringdown. FTP: File Transfer Protocol. A TCP/IP standard protocol for transferring files Gateway: A communications device that connects two different networks. Header: The beginning of a frame or cell that contains management and addressing information.
Mbps: Megabits per second. One megabit is 1,048,576 (10242) bits. NAT: Network Address Translation is a transparent routing function that translates a Private IP address on a PAT into a Public address that can be used in a public network. Network address: The network portion of an IP address. Network protocol: Network protocols encapsulate and forward data packets from one interface to another. Noise: Unwanted interference to a transmitted signal by an outside source.
Routing table: A table that lists routing paths to enable a node to route traffic to another node in the network. Server: Hardware or software that offers a specific service, such as database management, to a client. Static route: A route that is permanent rather than a route that is dynamically assigned by another router. STP: Shielded Twisted Pair. Telephone wire that is wrapped in a sheath to eliminate external interference.
