Overview
Thank you for purchasing the NetComm NB1 ADSL/ADSL2 Modem Router. NetComm brings you the Next Generation of ADSL technology with ADSL-2*, which
boosts ADSL’s performance, improves interoperability, and supports new applications, services and deployment conditions.
NetComm’s implementation of ADSL-2* and ADSL-2+* ensures that the NB1 operates with existing ADSL services while delivering optimal performance in all modes
of operation. Powered by the latest ADSL-2* TI chipset, NetComm’s NB1 increases
downstream data rates by up to 50% (12Mbps) and 100% (25Mbps) for ADSL2
Plus* mode ensuring that you can surf the net or download your files quicker than
ever before.
Security is a key issue with Broadband users and NetComm’s NB1 does not leave
you exposed. Employing the latest Active Firewall technology, the NB1 checks every
packet of data that comes in ensuring your defences are rock-solid against hackers,
unauthorised entries, probes and even Denial of Service attacks. What’s more, the
NB1 is equipped with a VPN pass-through feature allowing you to use a standard
VPN client for Point-to-Point communication even while your Firewall is active.
The NB1 delivers the connection versatility needed to cater for today’s ADSL users.
You can simply attach the NB1 to a single PC via the Ethernet port. Alternatively,
should you wish to share your Internet connection, the NB1 is equipped with an
in-built Router which will support multiple PCs with the addition of device such as a
NetComm 5- or 8-port Network Switch.
The NB1’s Port Forwarding and UPnP functions have made it easier for today’s Internet users to configure and setup the myriad of Network Port Rules needed by Internet applications such as On-Line Gaming, Peer-To-Peer file sharing and Messenger
services to operate. NB1 has a number of pre-configured rules for several games,
just click on the game you wish to play on-line and the rest is done for you.
Added to this, the NB1 introduces a QoS (Quality of Service) feature that gives you
control over which types of outgoing data are given priority by the router. With QoS
you can tailor your router settings to ensure that you can keep gaming or browsing
even though your upstream bandwidth may be saturated by applications such as
Peer-To-Peer file sharing.
* Your ISP must support and provide you with an ADSL-2 or ADSL-2+ service for these features to be available. This
product will operate as a standard ADSL Modem Router when an ADSL-2 service is not available.
This reference manual assumes that the reader has an installed Ethernet card in the computer to be connected and
has basic to intermediate computer and Internet skills. However, basic Computer Networking, Internet, and Firewall
technology information is available from the NetComm Web site. See www.netcomm.com.au.
Note that due to the fact that the NB1 is an adaption of the NB5 multi-port router, several functions belonging to
the NB5 including LAN Groups are still represented by screens in the NB1 firmware. These screens to not have a
corresponding function in this model which will be noted in the manual where applicable.

Do I need a Micro filter?
Micro filters are used to prevent common telephone equipment, such as phones,
answering machines and fax machines, from interfering with your ADSL service. If
your ADSL enabled phone line is being used with any other equipment other than
your ADSL Modem then you will need to use one Micro filter for each phone device.
Splitters may be installed when your ADSL line is installed or when your current
phone line is upgraded to ADSL. If your telephone line is already split you will not
need to use a Microfilter - check with your ADSL service provider if you are unsure.
Each micro filter is connected in-line with your telephone or fax machine so that all
signals pass through it. Telephones and/or facsimiles in other rooms that are using
the same extension will also require Microfilters. The following diagram gives an
example of connecting your ADSL Modem/Router using a Microfilter.

Restoring Factory Defaults
This feature will reset the Modem to its factory default configuration. Occasions may
present themselves where you need to restore the factory defaults on your modem.
Typical situations are:
•
You have lost your username and password and are unable to login to the modem.
•
You have purchased the modem from someone else and need to reconfigure the
device to work with your ISP.
•
You are asked to perform a factory reset by a member of the NetComm Support
staff.
In order to restore your modem to its factory default settings, please follow these
steps:
•
Ensure that your Modem is powered on (for at least 10 seconds).
•
Use a paper clip or a pencil tip to depress the reset button for ten seconds and
release. At this point, the reset is in progress. Do not power off the unit at this
point.
•
When indicator lights return to steady green, reset is complete. The default settings are now restored. The entire process takes about 45 seconds to complete.
•
Once you have reset the modem to its default settings you will be able to access
the device's configuration web interface using http://192.168.1.1 with username
'admin' and password 'admin'.

Configuring your NB1
You will need to log directly into the configuration page of the modem and configure
the basic settings for your Internet connection. Your ISP should provide you with the
necessary information to complete this step.
The settings that you most likely need to change to access the Internet are grouped onto
a single EasyConfig page.
To configure your modem follow the steps below:
Note:
Ensure that your PC is setup as a DHCP client. Refer to the Computer
Hardware Configuration section for instructions on how to set this up with
different Operating Systems.
1. Insert the CD into your CD-ROM drive. An autorun screen will appear. Click on
Configure Modem.
(Alternatively, if the CD-ROM is not available, you can open a web
browser and type http://192.168.1.1 in the location bar to access the
modem’s EasyConfig setup screen directly.)
2. The login page will be displayed. Enter the modem’s username and password.
The default username is admin.
The default password is admin.
Click on Log In.
3. The EasyConfig page will be displayed.
NB1 Quick Start Guide
12
YML781 Rev1
www.netcomm.com.au
4. Check with your ISP what Protocol your modem needs to use to connect to the
Internet. If unsure, leave the default selection of PPPoE.
5. In the User ID field, enter the Username that your ISP has provided. In the
password field, enter the password that your ISP has given you.
Note:
If your ISP has provided you with Static addressing details you will need
to access the Advanced Settings of your modem to configure these. Please
refer to the section on Advanced Settings in the User Guide on the CD ROM
for instructions.
6. The default VPI / VCI settings for most connections is 8 / 35 in Australia. Do not
change these unless your ISP has instructed you to do so.
7. Click on the Apply button to save the settings you have entered. The modem will
automatically reboot. Refresh the web page after 20 seconds.
8. If the settings you entered were correct and you have an ADSL connection established the Status light will change to green.
9. You should now be able to access the Internet with a web browser, email client
or other Internet application.
10. If the status light remains red after 45 seconds and you have refreshed your
web page several times, check the following:
•
ADSL Link light on your modem is solid green; If not, you do not have an
ADSL connection established. Contact your ISP who will assist in resolving
this.
•
If you have a solid green light on your modem for the ADSL Link, but you
can’t access the Internet, check that the username / password you entered
are correct and try again;
•
If the above two suggestions don’t resolve the issue, please contact your ISP;
TIP:
To test your Internet connection while the modem is attempting to apply
the settings, you can open a DOS prompt (Start > Run > cmd) and execute
a continual ping command to a public server’s IP address on the Internet.
Once you receive a reply from the server you know that you are connected.
This can take up to 30 seconds. e.g: c:/ ping 210.0.111.111 -t

RJ-45 Network Ports
RJ-45 Network Ports can connect any networking devices that use a standard LAN
interface, such as a Hub/Switch Hub or Router. Use unshielded twisted-pair (UTP)
or shield twisted-pair (STP) cable to connect the networking device to the RJ-45
Ethernet port. Depending on the type of connection, 10Mbps or 100Mbps, use the
following Ethernet cable, as prescribed.
10Mbps: Use EIA/TIA-568-100-Category 3, 4 or 5 cable.
100Mbps: Use EIA/TIA-568-100-Category 5 cable.
Note:
To prevent loss of signal, make sure that the length of any twisted-pair
connection does not exceed 100 metres.

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. In a crossover cable, the wires of 1,2,3,6 are reversed so that wire 1 become 3 at the other end of the cable, 2 becomes 6, and so
forth.
To determine which wire is wire 1, hold the RJ-45 cable tip with the spring clip
facing towards the ground and the end pointing away from you. The copper wires
exposed upwards to your view. The first wire on the far left is wire 1. You can also
refer to the illustrations and charts of the internal wiring on the following page.

Appendix C: Glossary
10BASE-T
A designation for the type of wiring used by Ethernet
networks with a data rate of 10 Mbps. Also known as
Category 3 (CAT 3) wiring. See also data rate, Ethernet.
100BASE-T
A designation for the type of wiring used by Ethernet
networks with a data rate of 100 Mbps. Also known as
Category 5 (CAT 5) wiring. See also data rate, Ethernet.
ADSL
Asymmetric Digital Subscriber Line. The most commonly
deployed type of DSL for home users. The term asymmetrical refers to its unequal data rates for downloading and uploading (the download rate is higher than the
upload rate). The asymmetrical rates benefit home users
because they typically download much more data from
the Internet than they upload.
analog
Of data, having a form is analogous to the data’s original waveform. The voice component in DSL is an analog
signal. See also digital.
ATM
Asynchronous Transfer Mode A standard for high-speed
transmission of data, text, voice, and video, widely used
within the Internet. ATM data rates range from 45 Mbps
to 2.5 Gbps. See also data rate.
authenticate
To verify a user’s identity, such as by prompting for a
password.
binary
The “base two” system of numbers, that uses only two
digits, 0 and 1, to represent all numbers. In binary, the
number 1 is written as 1, 2 as 10, 3 as 11, 4 as 100, etc.
Although expressed as decimal numbers for convenience,
IP addresses in actual use are binary numbers; e.g., the
IP address 209.191.4.240 is 11010001.10111111.000001
00.11110000 in binary. See also bit, IP address, network
mask.
bit
Short for “binary digit,” a bit is a number that can have
two values, 0 or 1. See also binary.
bps
bits per second
bridging
Passing data from your network to your ISP and vice
versa using the hardware addresses of the devices at
each location. Bridging contrasts with routing, which can
add more intelligence to data transfers by using network
addresses instead. The My ADSL Modem can perform
both routing and bridging. Typically, when both functions
are enabled, the device routes IP data and bridges all
other types of data. See also routing.
broadband
A telecommunications technology that can send different
types of data over the same medium. DSL is a broadband
technology.
Broadcast
To send data to all computers on a network.

found. xDSL lines running from a subscriber’s home connect at their serving central office.
DHCP
Dynamic Host Configuration Protocol
DHCP automates
address assignment and management. When a computer
connects to the LAN, DHCP assigns it an IP address from
a shared pool of IP addresses; after a specified time limit,
DHCP returns the address to the pool.
DHCP relay
Dynamic Host Configuration Protocol relay. A DHCP relay
is a computer that forwards DHCP data between computers that request IP addresses and the DHCP server that
assigns the addresses. Each of the My ADSL Modem’s
interfaces can be configured as a DHCP relay. See DHCP.
DHCP server
Dynamic Host Configuration Protocol server. A DHCP
server is a computer that is responsible for assigning IP
addresses to the computers on a LAN. See DHCP.
digital
Of data, having a form based on discrete values expressed as binary numbers (0’s and 1’s). The data component in DSL is a digital signal. See also analog.
DNS
Domain Name System. The DNS maps domain names
into IP addresses. DNS information is distributed hierarchically throughout the Internet among computers called
DNS servers. When you start to access a web site, a DNS
server looks up the requested domain name to find its
corresponding IP address. If the DNS server cannot find
the IP address, it communicates with higher-level DNS
servers to determine the IP address. See also domain
name.
domain name
A domain name is a user-friendly name used in place of
its associated IP address. For example, www.globespan.
net is the domain name associated with IP address
209.191.4.240. Domain names must be unique; their
assignment is controlled by the Internet Corporation for
Assigned Names and Numbers (ICANN). Domain names
are a key element of URLs, which identify a specific file at
a web site, e.g., http://www.globespan.net/index.html.
See also DNS.
download

IP address
Internet Protocol address The address of a host (computer) on the Internet, consisting of four numbers, each
from 0 to 255, separated by periods, e.g., 209.191.4.240.
An IP address consists of a network ID that identifies
the particular network the host belongs to, and a host
ID uniquely identifying the host itself on that network. A
network mask is used to define the network ID and the
host ID. Because IP addresses are difficult to remember,
they usually have an associated domain name that can be
specified instead. See also domain name, network mask.
ISP
Internet Service Provider A company that provides Internet access to its customers, usually for a fee.
LAN
Local Area Network A network limited to a small geographic area, such as a home, office, or small building.
LED

per second. Network data rates are often expressed in
Mbps.
Microfilter
In splitterless deployments, a microfilter is a device that
removes the data frequencies in the DSL signal, so that
telephone users do not experience interference (noise)
from the data signals. Microfilter types include in-line (installs between phone and jack) and wall-mount (telephone jack with built-in microfilter). See also splitterless.
NAT
Network Address Translation A service performed by
many routers that translates your network’s publicly
known IP address into a Private IP address for each computer on your LAN. Only your router and your LAN know
these addresses; the outside world sees only the public IP
address when talking to a computer on your LAN.
NAT rule
A defined method for translating between public and private IP addresses on your LAN.

network
A group of computers that are connected together, allowing them to communicate with each other and share
resources, such as software, files, etc.A network can be
small, such as a LAN, or very large, such as the Internet.
network mask
A network mask is a sequence of bits applied to an IP
address to select the network ID while ignoring the host
ID. Bits set to 1 mean “select this bit” while bits set to 0
mean “ignore this bit.” For example, if the network mask
255.255.255.0 is applied to the IP address 100.10.50.1,
the network ID is 100.10.50, and the host ID is 1. See
also binary, IP address, subnet
NIC
Network Interface Card An adapter card that plugs into
your computer and provides the physical interface to your
network cabling, which for Ethernet NICs is typically an
RJ-45 connector. See Ethernet, RJ-45.

or router, through which data flows into and out of the
device.
POTS
Plain Old Telephone Service Traditional analog telephone
service using copper telephone lines. Pronounced pots.
See also PSTN.
POTS splitter
See splitter.
PPP
Point-to-Point Protocol A protocol for serial data transmission that is used to carry IP (and other protocol) data
between your ISP and your computer. The WAN interface
on the My ADSL Modem uses two forms of PPP called PPPoA and PPPoE. See also PPPoA, PPPoE.
PPPoA
Point-to-Point Protocol over ATM One of the two types of
PPP interfaces you can define for a Virtual Circuit (VC),
the other type being PPPoE. You can define only one PPPoA interface per VC.
PPPoE
Point-to-Point Protocol over Ethernet One of the two
types of PPP interfaces you can define for a Virtual Circuit
(VC),the other type being PPPoA. You can define one or
more PPPoE interfaces per VC.

splitter
A device that splits off the voice component of the DSL
signal to a separate line, so that data and telephone
service each have their own wiring and jacks. The splitter
is installed by your telephone company where the DSL
line enters your home. The CO also contains splitters that
separate the voice and data signals, sending voice to the
PSTN and data on high-speed lines to the Internet. See
also CO, PSTN, splitterless, microfilter.
splitterless
A type of DSL installation where no splitter is installed,
saving the cost of a service call by the telephone company. Instead, each jack in the home carries both voice and
data, requiring a microfilter for each telephone to prevent
interference from the data signal. ADSL is usually splitterless; if you are unsure if your installation has a splitter,
ask your DSL provider. See also splitter, microfilter.
subnet
A subnet is a portion of a network. The subnet is distinguished from the larger network by a subnet mask
which selects some of the computers of the network
and excludes all others. The subnet’s computers remain
physically connected to the rest of the parent network,
but they are treated as though they were on a separate
network. See also network mask.

TCP/IP
Transmission Control Protocol/Internet Protocol The basic
protocols used on the Internet. TCP is responsible for dividing data up into packets for delivery and reassembling
them at the destination, while IP is responsible for delivering the packets from source to destination. When TCP
and IP are bundled with higher-level applications such as
HTTP, FTP, Telnet, etc., TCP/IP refers to this whole suite of
protocols.
Telnet
An interactive, character-based program used to access a
remote computer. While HTTP (the web protocol) and FTP
only allow you to download files from a remote computer,
Telnet allows you to log into and use a computer from a
remote location.
TFTP
Trivial File Transfer Protocol. A protocol for file transfers,
TFTP is easier to use than File Transfer Protocol (FTP) but
not as capable or secure.
TTL
Time To Live A field in an IP packet that limits the life
span of that packet. Originally meant as a time duration,
the TTL is usually represented instead as a maximum hop
count; each router that receives a packet decrements this
field by one. When the TTL reaches zero, the packet is
discarded.
twisted pair
The ordinary copper telephone wiring long used by telephone companies. It contains one or more wire pairs
twisted together to reduce inductance and noise. Each
telephone line uses one pair. In homes, it is most often
installed with two pairs. For Ethernet LANs, a higher
grade called Category 3 (CAT 3) is used for 10BASET networks, and an even higher grade called Category
5 (CAT 5) is used for 100BASE-T networks. See also
10BASE-T, 100BASE-T, Ethernet.
upstream
The direction of data transmission from the user to the
Internet.
USB
Universal Serial Bus A serial interface that lets you connect devices such as printers, scanners, etc. to your computer by simply plugging them in. The My ADSL Modem is
equipped with a USB interface for connecting to a standalone PC.
VC
Virtual Circuit A connection from your ADSL router to your
ISP.
VCI
Virtual Circuit Identifier Together with the Virtual Path
Identifier (VPI), the VCI uniquely identifies a VC. Your
ISP will tell you the VCI for each VC they provide. See
also VC.
VPI
Virtual Path Identifier Together with the Virtual Circuit
Identifier (VCI), the VPI uniquely identifies a VC. Your ISP

web sites, and displays the information, which may consist of text, graphic images, audio, or video, to the user.
Web browsers use Hyper-Text Transfer Protocol (HTTP).
Popular web browsers include Netscape Navigator and Microsoft Internet Explorer. See also HTTP, web site, WWW.
Web page
A web site file typically containing text, graphics and
hyperlinks (cross-references) to the other pages on that
web site, as well as to pages on other web sites. When a
user accesses a web site, the first page that is displayed
is called the Home page. See also hyperlink, web site.
