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 applica-
tions, 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 files 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 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. NB5Plus4/W 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 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 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.

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 mo-
dem.
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 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 configuration 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 com-
puter 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.

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 this manual 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 es-
tablished 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 a
connection established with your local DSLAM. Please call your ISP who will
assist in resolving this.
•
If you have a solid green light on your modem for the ADSL Link, 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

Interfaces
This section displays the available interfaces on your modem that have yet to be
configured. 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)
iii)
Ethernet;
WLAN (Wireless LAN);
two if you have the NB5Plus4:
i)
USB;
ii)
Ethernet;
LAN Groups
Configuring 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 configuration:
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

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
the interface and click the Add button of the appropriate LAN group. To add the
available USB interface to LAN group 2 highlight the USB interface in the Interfaces

IP Settings
The IP address is usually 192.168.1.1 but you can change it to another suitable
number (e.g. 192.168.0.1 or 10.0.0.1 or 172.16.1.1) to suit any existing network
devices you already have installed. The NetMask describes how big your network is,
the default 255.255.255.0 will allow for 253 computers and generally does not need
to be changed unless to suit existing network requirements.
Note:
If you change your IP address the DHCP server in your modem will auto-
matically change the IP address range (DHCP pool) it hands out accord-
ingly.

DHCP stands for Dynamic Host Configuration Protocol. Your Modem has its DHCP
Server enabled by default. This means it will assign valid IP addresses to each
computer connected to it and will direct those computers to use the Modem as the
gateway to the Internet. Having the DHCP server enabled is the recommended
choice.
When selecting certain radio buttons you will notice that some of the options avail-
able for configuration will be greyed out. For example, when selecting ‘Unmanaged’
you will notice that all fields under IP Settings are greyed out. This means that no
settings are configurable if the interface is unmanaged.

address is specified on all computers
on your network as the Gateway IP
address. The IP address is also the IP
address you type into your browser lo-
cation bar to login to your modem’s web
interface.
Note:
If Server and Relay are turned off you need to assign IP addresses within
the same range to the PCs connected to the modem else they will not
be able to communicate with the modem. For example, if your mo-
dem’s Ethernet interface address is 192.168.1.1 with a subnet mask of
255.255.255.0 you need to assign static addresses starting at 192.168.1.2
up to 192.168.1.253.
If you disable the DHCP server in the Modem you will need to either manually (stati-
cally) assign IP address information to each computer or use another device/com-
puter as DHCP server.
Note:
It is not recommended that you have more than one DHCP server enabled
on your network.

Advanced>IPQoS
IP QoS (Quality of Service) allows you to set priorities for traffic travelling through
your modem. For example, you may want to prioritize your UDP traffic over your
TCP traffic. Typical UDP traffic would be your VoIP (Voice over Internet Protocol)
traffic. 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 configure the upstream/downstream connection queue
priorities, and
2. A Rules configuration page.
QoS Setup Page
The QoS setup page will have 2 primary fields:
1. Connection name selection,
2. A table to select queue weights for the system transmit queues.
IP QoS traffic shaping is associated with any transmitted traffic 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 per-
cent 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 configuration page will allow the user to define IP matching fields to asso-
ciate with the priority queues associated with the named connections selected above
in the “QoS Setup Page” section.
There will be three primary fields for the user to select: 1.) A Trusted mode check
box. 2.) A traffic 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 traffic
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 first 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 first 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.

Rule definitions will be defined 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 define 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 traffic serv-
icing on the outgoing interface (facing the Access Network) using a 3-band priority
mechanism as described below.
Queue Priorities:

www.netcomm.com.au
One Expedited Forwarding (EF) Queue: High Priority queue with non-preemptible
service. The EF queue is always scheduled first 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
flow on the low priority queue thus preventing en-queuing high priority traffic. To
prevent such conditions the en-queuing process is using a simple configurable al-
location of per-queue lengths, adding up to the total queue length.
Configuration:
The Expedited Forwarding queue (fast service queue) length will be configurable via
the config.xml file. This parameter will not be configurable via the Web UI. Please
call NetComm Support and request to speak with an engineer should you require
this XML file to edit.

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 overflowing their queues will be tail-dropped, penalizing stochastically the
greediest flow within each queue.
Future implementations may introduce a “buffer stealing” policy. This policy will re-
move the fixed buffer limits and allow a particular queue buffer to decrease to some
predefined minimum limit.
De-queuing Policy
Expedited Forwarding Queue (High Priority) is always serviced first at each packet
scheduling cycle and serviced to extinction. Therefore, the EF queue is non-preemti-
ble by the Medium and Low priority queues.
WRR Queue Scheduler for Medium and Low priority queues
The L and M weights will be configured 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 configurable weights assigned to these queues. Each ar-
ray 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.

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 traffic shared over same PVC with Data traffic, the simple packet classifi-
cation and prioritization will not suffice to achieve the low latency required by voice.
In this case, a voice call triggers dynamic flushing 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 interleav-
ing of voice and data. Below is an example of MTU calculations:

For Voice traffic priority an extra EF queue was added to PRIOWRR. This extra
queue should not be exposed via WebUI config 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 config. This means that voice signalling can be mixed with data if user
configures data for High Priority.

Advanced > Bridge Filters
Bridge filtering enables rules to be defined which allow or deny data to pass through
the Router based on the source and destination Bridge address and data type of
each data frame.
To access Bridge Filters Control, click on Advanced>Bridge Filters.
Usage examples of Bridge Filter Rules are: to specify which computers on a network
are allowed Internet access; or to determine which particular computers are allowed
to access services provided by the Router (the last point is particularly relevant for
routers serving Wireless Networks as it can be used to prevent unauthorised people
from attaching themselves to a wireless LAN).
Enable/Disable Bridge Filtering
To enable Bridge filtering, navigate to the Bridge Filter Control Screen and select the
Enable Bridge Filters check box.
If the check box is selected, Bridge filtering is enabled according to the list of Bridge
Filter Rules that has been created.
If the box is de-selected, Bridge Filtering will not be enabled, even if Bridge Filter
Rules have been created.
Create Bridge Filter Rules
Enter the Source Bridge and Destination Bridge details. Entering zeros or blanks
into the Source or Destination fields enters a null value.
‘Protocol’ provides the choice of protocol type for the rule.
‘Mode’ provides the choice of Allow or Deny for the rule.
When all selections are made, click on Add to add the rule to the list of rules. A
maximum of 20 Bridge Filter Rules can be defined and saved.

both the starting and ending port numbers in the range, which are mapped by the
start port and end port fields.
The Destination Port Map field specifies the internal port that the data will be
directed to on the LAN Client. When dealing with port ranges, the Internal Port (des-
ignated by the Port Map field) will be the same as the first port in the range. When
you simply want to forward a single port from outside (i.e. WAN side) to inside (i.e.

Modem Firewall. The default ‘Firewall On’ setting blocks all anonymous Internet
traffic. Access control enables the user to selectively direct such traffic, for example
to a Web Host in the DMZ or to specific ports opened for such applications as Web,
Telnet or FTP.
CAUTION: This dialog box indicates that you should not disable LAN Web Access
or else you might not be able to connect to the device. If you become
locked out of the device perform a Restore Factory Default as detailed
earlier in this manual.
To configure Access Control, click on Advanced>Access Control. This will reveal the

your LAN for applications of the class indicated by the relevant check boxes. If Ac-
cess Control is not enabled, the individual check boxes cannot be checked.
If Access Control is enabled, and an Enable WAN checkbox is selected, then WAN
access to the matching service is enabled. In other words, for example, if your
were to enable Telnet access on the WAN you could then manage and configure
your modem from anywhere on the Internet via Telnet.

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 defined pathway that network information must travel to
reach the specific 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 con-
nection 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 first three fields of the New Destination IP, while the last field should
be 0. The Subnet Mask identifies 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 net-
work 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 fulfilling this function then its IP
address will be entered in this field.

Dynamic Routing makes use of the RIP Protocol to allow the ADSL Router to au-
tomatically 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
hops between the Source and the Destination. The RIP protocol regularly broadcasts
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 traffic from the Internet to the LAN if a specific 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.

Thus Port Forwarding is necessary to run certain games, chat clients, video-confer-
encing and other kinds of applications. You might also need to configure port-for-
warding 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 ap-
plication program (usually a server) incoming connections should be delivered to.
Some ports have numbers that are pre-assigned to them by the IANA (the Inter-
net 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 file-sharing applications) and
are using NAT (Network Address Translation), then you will usually need to config-
ure your router to forward these incoming connection attempts using specific 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 traffic 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

Wireless>Security>WEP
WEP (Wired Equivalent privacy) is a security protocol for Wireless Local Area Net-
works (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 configured with the same key.
The screen below illustrates the default setting of the WEP Wireless Security screen.
WEP is enabled by default.

Wireless > Security > 802.1x
802.1x is a security protocol for Wireless Local Area Networks (WLAN). It is a port-
based network access control that keeps the network port disconnected until au-
thentication is completed. 802.1x is based on the Extensible Authentication protocol
(EAP). EAP messages from the authenticator to the authentication server typically
use the RADIUS (Remote Authentication Dial-In User Service) protocol. The screen-
shot below illustrates the default setting of the 802.1x Wireless Security screen.

Wireless>Security>WPA
WPA (Wi-Fi Protected Access) is a security protocol for Wireless Local Area Networks
(WLAN). WPA uses a sophisticated key hierarchy that generates new encryption
keys each time a mobile device establishes itself with an access point. Protocols in-
cluding 802.1X, EAP and RADIUS are used for strong authentication. Like WEP, keys
can still be entered manually (preshared keys); however, using a RADIUS authenti-
cation server provides automatic key generation and enterprise-wide authentication.

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 Ca-
bles 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 re-
versed 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.

phone 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 com-
puter 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 pri-
vate IP addresses on your LAN.

ꢀetwork 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

PPP
Point-to-Point Protocol A protocol for serial data transmis-
sion 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 PP-
PoA and PPPoE. See also PPPoA, PPPoE.
PPPoA
PPPoE
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 PP-
PoA interface per VC.
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.
protocol
A set of rules governing the transmission of data. In order
for a data transmission to work, both ends of the connec-
tion have to follow the rules of the protocol.
remote
RIP
In a physically separate location. For example, an
employee away on travel who logs in to the company’s
intranet is a remote user.
Routing Information Protocol The original TCP/IP routing
protocol. There are two versions of RIP: version and ver-
sion II.
RJ-11
Registered Jack Standard-11 The standard plug used to
connect telephones, fax machines, modems, etc. to a
telephone jack. It is a 6-pin connector usually containing
four wires.
RJ-45
Registered Jack Standard-45 The 8-pin plug used in
transmitting data over phone lines. Ethernet cabling usu-
ally uses this type of connector.
routiꢀꢂ
Forwarding data between your network and the Internet
on the most efficient route, based on the data’s destina-
tion IP address and current network conditions. A device
that performs routing is called a router.
rule
See filtering rule, NAT rule.
SDNS
Secondary Domain Name System (server) A DNS server
that can be used if the primary DSN server is not avail-
able. See DNS.
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 compa-
ny. 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 split-
terless; if you are unsure if your installation has a splitter,
ask your DSL provider. See also splitter, microfilter.
subꢀet
A subnet is a portion of a network. The subnet is dis-
tinguished 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.
subꢀet mask
TCP
A mask that defines a subnet. See also network mask.
See TCP/IP.
TCP/IP
Transmission Control Protocol/Internet Protocol The basic
protocols used on the Internet. TCP is responsible for di-
viding data up into packets for delivery and reassembling
them at the destination, while IP is responsible for deliv-
ering 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.
Telꢀet
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
TTL
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.
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 tel-
ephone 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 10BASE-
T networks, and an even higher grade called Category
5 (CAT 5) is used for 100BASE-T networks. See also
10BASE-T, 100BASE-T, Ethernet.
