Overview
Thank you for purchasing the NetComm NB5Plus4/W 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 NB5Plus4/
W operates with existing ADSL services while delivering optimal performance in
all modes of operation. Powered by the latest ADSL-2* TI chipset, NetComm’s
NB5Plus4/W 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 les quicker than ever before.
Security is a key issue with Broadband users and NetComm’s NB5Plus4/W does not
leave you exposed. Employing the latest Active Firewall technology, the NB5Plus4/
W 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 NB5Plus4/W 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 NB5Plus4/W delivers the connection versatility needed to cater for today’s ADSL
users. You can simply attach the NB5Plus4/W to a single PC by using the USB port
or Ethernet port. Alternatively, should you wish to share your Internet connection,
the NB5Plus4/W is equipped with an in-built Router and four 10/100 Ethernet ports
for connection to a network. If you have the NB5Plus4W modem, you can share
your Internet connection wirelessly.
The NB5Plus4/W’s Port Forwarding and UPnP functions have made it easier for
today’s Internet users to congure and setup the myriad of Network Port Rules
needed by Internet applications such as On-Line Gaming, Peer-To-Peer le sharing
and Messenger services to operate. NB5Plus4/W has a number of pre-congured
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 NB5Plus4/W 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 le 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.

Do I need a Micro filter?
Micro lters 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 lter 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 Microlter - check with your ADSL service provider if you are unsure.
Each micro lter 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 Microlters. The following diagram gives an
example of connecting your ADSL Modem/Router using a Microlter.

Restoring Factory Defaults
This feature will reset the Modem to its factory default conguration. 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 mo-
dem.
• You have purchased the modem from someone else and need to recongure 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 set-
tings 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 conguration web interface using http://192.168.1.1 with username
'admin' and password 'admin'.

Connecting your NB5Plus4/W
The NB5Plus4/W can be connected via a USB cable or an Ethernet cable or both. The USB
connection is simply an ethernet simulation. As far as your computer is concerned the
USB connection is an Ethernet connection, hence DHCP and other protocols will work the
same as for Ethernet.
To connect to your ADSL Router, you need to have either an Ethernet Port or a USB
Port present on your Computer/Notebook.
Connecting your NB5Plus4/W ADSL Modem via ETHERNET
1. Connect your NB5Plus4/W to either a computer directly or a network hub or
switch using CAT5 ethernet cables.
2. Connect the power pack to the ADSL Modem and switch on the power switch.
3. Ensure that there is a LAN link light on the NB5Plus4/W.
4. Ensure that the computer you intend to use has an IP address in the same
subnet as the NB5Plus4/W ADSL Modem. (e.g. the NB5Plus4/W’s default IP is
192.168.1.1 - your computer should be on 192.168.1.100 or similar.) If you
have DHCP enabled on your computer, the NB5Plus4/W will assign your computer a suitable IP address.
5. Ensure that your computer has a LAN link light.
6. Connect one end of the ADSL phone line to the NB5Plus4/W ADSL Modem and
the other end to the wall socket.
YML754 Rev1 NB5Plus4/W User Guide

Interfaces
This section displays the available interfaces on your modem that have yet to be
congured. The default setting is to have all interfaces in LAN group 1.
It is possible to have separate LAN groups:
• three if you have the NB5Plus4W:
i) USB;
ii) Ethernet;
iii) WLAN (Wireless LAN);
• two if you have the NB5Plus4:
i) USB;
ii) Ethernet;
LAN Groups
Conguring LAN Groups with static IP addresses must be done in such a way that
the range of assignable IP addresses in each of the LAN groups should not overlap
with other LAN groups. A rule of thumb would be that each LAN group should be
on its own network or subnet. For example, say you have 3 LAN groups each being
setup with static IP addressing. Below is a sample conguration:
LanGroup #1
IP Address 192.168.1.1
NetMask 255.255.255.0
LanGroup #2
IP Address 192.168.2.1
NetMask 255.255.255.0
NB5Plus4/W User Guide YML754Rev1
22 www.netcomm.com.au
LanGroup #3
IP Address 192.168.3.1
NetMask 255.255.255.0
The above example shows that each LAN group is on its own network and that there
is no overlap in assignable IP address based on netmask.
To remove an interface from LAN group 1, click on the interface (e.g. USB) and click
the Remove button:
To add the available interface from the Interfaces section to a LAN group, highlight

Advanced>IPQoS
IP QoS (Quality of Service) allows you to set priorities for trafc travelling through
your modem. For example, you may want to prioritize your UDP trafc over your
TCP trafc. Typical UDP trafc would be your VoIP (Voice over Internet Protocol)
trafc. This section describes how to make use of your modem’s IPQoS feature.
The NB5Plus4/W should have two primary sections for setting up IP QoS services:
1. A QoS setup page to congure the upstream/downstream connection queue
priorities, and
2. A Rules conguration page.
QoS Setup Page
The QoS setup page will have 2 primary elds:
1. Connection name selection,
2. A table to select queue weights for the system transmit queues.
IP QoS trafc shaping is associated with any transmitted trafc from the perspective
of the NB5Plus4/W. Each interface has 3 priority queues associated with transmit
data. The web UI will allow the user to choose any interface connection and select
the priority weights associated with that connection. For Example; the user could
have a connection named WAN1 or a connection named LAN1. If the user selects
WAN1 the transmit queues will be associated with that connection, and likewise
with LAN1 (Refer to the following diagrams). All interfaces on the LAN are currently
bridged and therefore the only connection name is that name associated with the
LAN.
Transmit queues associated with WAN connection
Transmit queues associated with LAN connection
The high priority queue has strict priority over the medium and low priority queue,
and therefore can exhaust all available bandwidth. The web UI will allow the user to
select the weights of the medium and low priority queues in increments of 10 percent so that the sum of the weights of the 2 queues is equal to 100 percent. These
queues will be serviced on a Round Robin priority basis according to the weights
assigned, after the high priority queue has been completely serviced.
Rules Configuration Page
The Rules conguration page will allow the user to dene IP matching elds to associate with the priority queues associated with the named connections selected above
in the “QoS Setup Page” section.
There will be three primary elds for the user to select: 1.) A Trusted mode check
box. 2.) A trafc priority choice (High, Medium, Low), and 3.) An IP rules matching
selection area.
The NB5Plus4/W has two primary modes of operation with regard to queue trafc
prioritization; Trusted, and Un-trusted. The Web UI will provide one check box to
enable trusted mode. In trusted mode all rules will be applied rst regardless of the
setting of the TOS bits. After the rules have been exhausted the existing TOS bit
settings will be honoured. If the “Trusted mode” box is unchecked this will indicate
the “Un-trusted mode.” “Un-trusted” mode will match rst against all rules as in
“Trusted” mode. The difference is that if there is no match then a default rule will be
used. The default rule will have an associated queuing priority.
YML754 Rev1 NB5Plus4/W User Guide
www.netcomm.com.au 43
Rule denitions will be dened by the user by allowing the user to select matching
based on Source IP, Destination IP, IP Protocol, Source Port, Destination Port, and
Incoming Mac Port (switched LAN Port). These selections will dene a rule and be
associated with a particular queue priority: High, Medium, and Low.
Traffic Queuing Configuration
Based on the TOS (DSCP) marking, the NB5Plus4/W shall prioritize the trafc servicing on the outgoing interface (facing the Access Network) using a 3-band priority
mechanism as described below.
Queue Priorities:
NB5Plus4/W User Guide YML754Rev1
44 www.netcomm.com.au
One Expedited Forwarding (EF) Queue: High Priority queue with non-preemptible
service. The EF queue is always scheduled rst prior to the medium and low priority
queues and runs to completion
Two Queues (Medium and Low Priority) with Weighted Round Robin service. Based
on the associated weights, packets on these queues share the remaining link
bandwidth (after the EF service). The low priority queue corresponds to Best Effort
service. Looking forward, the medium priority queue will play the role of Assured
Forwarding Queue.
Configuration:
a.) The Medium, and Low Priority Queue weights will be selectable via the Web UI.
User weights for these two queues are entered as a percentage in increments of
10%. The sum of the 2 weights must be equal to 100 percent.
En-queuing Policy
Inter-queue isolation to make greed work on the Residential Gateway: the transmit
interface buffer (a common pool for all queues) can be monopolized by a greedy
ow on the low priority queue thus preventing en-queuing high priority trafc. To
prevent such conditions the en-queuing process is using a simple congurable allocation of per-queue lengths, adding up to the total queue length.
Configuration:
The Expedited Forwarding queue (fast service queue) length will be congurable via
the cong.xml le. This parameter will not be congurable via the Web UI. Please
call NetComm Support and request to speak with an engineer should you require
this XML le to edit.
YML754 Rev1 NB5Plus4/W User Guide
www.netcomm.com.au 45
The Medium and Low priority queue lengths will be proportionally calculated via the
queue weights selected in 1.) Queue Priorities above.
Total queue length for all three queues will sum to the transmit queue length set in
the system.
Packets overowing their queues will be tail-dropped, penalizing stochastically the
greediest ow within each queue.
Future implementations may introduce a “buffer stealing” policy. This policy will re-
move the xed buffer limits and allow a particular queue buffer to decrease to some
predened minimum limit.
De-queuing Policy
Expedited Forwarding Queue (High Priority) is always serviced rst at each packet
scheduling cycle and serviced to extinction. Therefore, the EF queue is non-preemtible by the Medium and Low priority queues.
WRR Queue Scheduler for Medium and Low priority queues
The L and M weights will be congured from the Web UI as stated above in 1.)
Queue Priorities.
A service scheduling array will be pre-computed for the Medium and Low priority
queues based on the user congurable weights assigned to these queues. Each array slot corresponds to a scheduling cycle. The pre-computed algorithm will allo-
cate scheduling slots for each queue based on the Medium and Low priority queue
weights and uniformly interleave them through the scheduling array. This array will
provide an O(1) scheduler with a minimum possible average latency for each of the
two queues.
Configuration:
NB5Plus4/W User Guide YML754Rev1
46 www.netcomm.com.au
The weighted values used for the WRR scheduler will be calculated based on the
percentage weights the user inputs in the Web UI as stated above in 1.) Queue
Priorities.
Example: User selects a Medium Queue Weight = 60 %, and Low Queue Weight =
40%. Then the O(1) scheduling array will look like {L, M, M, L, M, M, L, M, M, L}
where L and M represents a scheduling cycle for the respective Low and Medium
queues.
Low Latency Queue (Fragmentation and Interleaving) for Voice Traffic
With Voice trafc shared over same PVC with Data trafc, the simple packet classication and prioritization will not sufce to achieve the low latency required by voice.
In this case, a voice call triggers dynamic ushing of existing data packets from
device queues (including DSL device driver) for Head of Line Blocking removal, and
IP MTU resizing based on uplink bandwidth for fragmentation and packet interleaving of voice and data. Below is an example of MTU calculations:
Total delay PSTN delay Maximum Data Fragment size
end-to-end budget based on upstream bandwidth (bytes)
For Voice trafc priority an extra EF queue was added to PRIOWRR. This extra
queue should not be exposed via WebUI cong for data usage. Its use is triggered
internally by the voice app using the socket options system calls. Voice packets are
using this EF queue. Signalling for Voice uses the next EF queue that’s also exposed
on the web cong. This means that voice signalling can be mixed with data if user
congures data for High Priority.
TOS-to-Priority Mapping
High Priority Marking for Expedited Forwarding Queue: DSCP Mark: xx1000
Medium Priority Marking: DSCP Mark: xx0100
Low Priority Marking for Best Effort: DSCP Mark: xx0000

across the router.
Custom IP Filters (often also referred to as ‘Access Control Lists’ ) allow you to
specify individual rules that will deny trafc by dening the following:
• Source IP address or IP Subnet
• Destination IP address or Subnet
• Port or Port range
• Protocol
Custom IP lters are different from Port forwards, or Block All trafc because they
allow greater scopes of IP addresses to be included in the block.
Note: You must have at least one LAN Client in your LAN clients table before IP
lters can be created. To create a LAN Client, see the section below on LAN

needs to be sent from one to many devices. Typical uses might include the updat-

Advanced > Static Routing
If the Router is required to serve more than one network, you will need to set up a
Static Route between the networks. Static routing can be used to allow users from
one IP domain to access the Internet through the Router in another domain. A
Static Route provides the dened pathway that network information must travel to
reach the specic host or network which is providing Internet access .
To access the Static Routing controls, click on Advanced> Static Routing.
Configuring Static Routing:
Choose a Connection: presents list of Saved Connections. Select appropriate connection from list.
The New Destination IP is the address of the remote LAN network or host to which
you want to assign a static route. Enter the IP address of the host for which you
wish to create a static route here. For a standard Class C IP domain, the network
address is the rst three elds of the New Destination IP, while the last eld should
be 0. The Subnet Mask identies which portion of an IP address is the network por-
tion, and which portion is the host portion. For a full Class C Subnet, the Subnet
Mask is 255.255.255.0. The Gateway IP address should be the IP address of the
gateway device that allows for contact between the Gateway and the remote network or host.
Gateway: IP address refers to the IP address of the near device that is to connect
with the remote network or host. If the Modem is fullling this function then its IP
address will be entered in this eld.

Dynamic Routing makes use of the RIP Protocol to allow the ADSL Router to automatically adjust to physical changes in the network. The NB5Plus4/W, using the
RIP protocol, will determine the network packet route based on the least number of

routing information to other Routers on the network and is part of the IP Suite.

Advanced>Port Forwarding
Port Forwarding is necessary because NAT [=Network Address Translation] only
forwards trafc from the Internet to the LAN if a specic port mapping exists in the
NAT translation table. Because of this, the NAT provides a level of protection for
computers that are connected to your LAN. However, this also creates a connectivity
problem when you want to make LAN resources available to Internet clients, which
you may want to do to play network games or host network applications.
YML754 Rev1 NB5Plus4/W User Guide
www.netcomm.com.au 61
Thus Port Forwarding is necessary to run certain games, chat clients, video-conferencing and other kinds of applications. You might also need to congure port-forwarding if you intend to host a web server or mail server that is to be visible outside
your LAN.
TIP: In situations where you are hosting a Web Site or, for example, setting up
a regular NetMeeting link, it is advisable to consider implementing a Fixed
IP address, otherwise the dynamic IP address allocated by DHCP will need
to be communicated prior to every user session.
More about Port Forwarding
In TCP/IP and UDP networks a port is a 16-bit number used to identify which application program (usually a server) incoming connections should be delivered to.
Some ports have numbers that are pre-assigned to them by the IANA (the Internet Assigned Numbers Authority), and these are referred to as “well-known ports”.
Servers follow the well-known port assignments so clients can locate them.
If you wish to run a server on your network that can be accessed from the WAN
(i.e. from other machines on the Internet that are outside your local network), or
any application that can accept incoming connections (e.g. Peer-to-peer/P2P soft-
ware such as instant messaging applications and P2P le-sharing applications) and
are using NAT (Network Address Translation), then you will usually need to congure your router to forward these incoming connection attempts using specic ports
to the PC on your network running the application. You will also need to use port
forwarding if you want to host an online game server.
The reason for this is that when using NAT, your publicly accessible IP address will
be used by and point to your router, which then needs to deliver all trafc to the
private IP addresses used by your PCs.
The Internet Assigned Numbers Authority (IANA) is the central coordinator for the
assignment of unique parameter values for Internet protocols. Port numbers range
NB5Plus4/W User Guide YML754Rev1
62 www.netcomm.com.au
from 0 to 65535, but only ports numbers 0 to 1023 are reserved for privileged services and are designated as “well-known ports”. The registered ports are numbered
from 1024 through 49151. The remaining ports, referred to as dynamic ports or
private ports, are numbered from 49152 through 65535.
Examples of well-known and registered port numbers are shown in Table 4, for further information, please see IANA’s website at: http://www.iana.org/assignments/

WEP (Wired Equivalent privacy) is a security protocol for Wireless Local Area Networks (WLAN). WEP provides security by encrypting the data that is sent over the
WLAN.
The NB5Plus4W supports 3 levels of WEP encryption:
• 64 Bit encryption
• 128Bit encryption
• 256 Bit encryption
With WEP, the receiving station must use the same key for decryption. Each radio
NIC and access point, therefore, must be manually congured with the same key.

keys each time a mobile device establishes itself with an access point. Protocols including 802.1X, EAP and RADIUS are used for strong authentication. Like WEP, keys
can still be entered manually (preshared keys); however, using a RADIUS authentication server provides automatic key generation and enterprise-wide authentication.

Appendix C: Cable Connections
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.
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.
Figure 1
Figures 1 and 2 illustrate the use of straight-through and crossover twisted pair
cables along with the connector.

RJ11 connector and cable
An RJ-11 connector is the small, modular plug used for most analog telephones. It
has six pin slots in the head, but usually only two or four of them are used.

605 to RJ-11 adapter
The 605 to RJ-11 adaptor is provided to comply with the older 610 Telstra wall
socket. The 605 to RJ-11 adapter may be used to convert the supplied RJ-11 cable,
if the older connection is required.

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 rst wire on the far left is wire 1. You can also
