Safety Notices and Warnings
SAFETY NOTICES and WARNINGS
THUNDERSTORMS and LIGHTNING
DO NOT USE Tieline codecs during thunderstorms and lightning.
You may suffer an injury using a phone, Tieline codec, or any device connected to
a phone during a thunderstorm
This can lead to personal injury and in extreme cases may be fatal.
Protective devices can be fitted to the line, however, due to the extremely high
voltages and energy levels involved in lightning strikes, these devices may not offer
protection to the users, the Tieline codec and equipment connected to the codec.
Secondary strikes can occur. These secondary strikes are induced by lightning
strikes and also produce dangerously high currents and energy levels. You only
need to be near an object struck by lightning to lead to personal injury or damage
to equipment. e.g. if located near a lighting tower at a sports facility, water features
and drains on golf courses you will be affected by these secondary strikes.
Damage to personnel and Tieline codecs may occur during thunderstorms, even if
the codec is turned off but is connected to the phone system or the power.
ANY DAMAGE TO A TIELINE PRODUCT CAUSED BY LIGHTNING or an
ELECTRICAL STORM WILL VOID THE WARRANTY.
WARNING: DIGITAL PHONE SYSTEMS
DO NOT CONNECT YOUR Tieline CODEC TO A DIGITAL PHONE SYSTEM.
PERMANENT DAMAGE MAY OCCUR!
If you are unfamiliar with any facility, check that the line you are using is NOT a
digital line. If the Tieline codec becomes faulty due to the use of a digital phone
system, the WARRANTY IS VOID.
Disclaimer
Whilst every effort has been made to ensure the accuracy of this manual we are not
responsible for any errors or omissions within it. The product specifications and
descriptions within this manual will be subject to improvements and modifications
over time without notice, as changes to software and hardware are implemented.

T E C H N O L O G Y
Section 1. IP & 3GIP – A New Frontier in Broadcasting
Welcome to the Tieline IP and 3GIP reference manual and the new frontier in
broadcasting. High-speed 3G data networks are changing the face of broadcasting
and Tieline is at the forefront of these technological changes - creating solutions for
the challenges they present.
As broadcasting moves inexorably towards predominantly packet-switched networks
(rather than traditional circuit switched networks), Tieline is providing ground-
breaking solutions for IP and 3GIP – while maintaining connectivity to existing
communication infrastructure. This provides the best of both worlds and ensures
your investment in Tieline products maximizes the return on your investment.
Make sure you have the latest IP software. Tieline’s new firmware release addresses
IP network congestion and changing link quality when broadcasting over IP. Version
1.6.xx brings you innovative and cutting edge IP connectivity that is reliable, simpler
to connect to and which reacts intuitively to network conditions. Tieline’s new
automatically adaptive jitter buffer, in conjunction with forward error correction,
helps you master packet-switched network connections – it really is simple!
1.1. About this Manual
This manual is divided into four sections. The first section is designed to get you
connected quickly and contains four initial parts with instructions on how to
quickly configure both studio and field unit codecs for IP broadcasting, as well as
quick start connection guides for wired and wireless IP connections. These four
parts are titled:
IP streaming quick start studio setup guide;
IP streaming quick start field unit setup guide;
10 simple steps to connect Tieline codecs (wired IP); and
3GIP quick start connection guide (wireless IP).
Most users will be satisfied with this information to successfully connect over IP
and 3GIP networks. Following these elements are three complete reference
sections that fully explain in detail all the technical elements of:
IP streaming over wired studio and field unit codec IP connections;
Wireless 3GIP streaming using Tieline 3G modules or USB modules
with either a 3G cell-phone or USB modem attached; and
IP streaming using SIP connections.
For advanced connection information and other useful IP broadcasting technical
detail, please consult these reference sections within this document. Please note
that Appendix 1 discusses IP line quality and firewalls with useful troubleshooting
tips.

1.3. IP Streaming Quick Start Studio Configuration
This guide is intended to help you configure your Internet connection and Tieline
codec in the studio to enable incoming calls over IP from a remote Tieline codec.
It is assumed that you have an understanding of your network, its devices and
configuration. In the studio you need to:
Order a dedicated static public IP address for the codec;
Program the IP connection and static IP address details using the IP
wizard; and
Follow the simple 10 step connection procedure to dial and connect.
1.3.1. Steps for Programming Studio Network
Connectivity
•Order a high-speed broadband service from your
Internet Service Provider (ISP) & do not share this
connection with other devices. Order a ‘static public
IP address’ from your ISP where possible.
•Get your network administrator to ‘install’ the static
public IP address and perform Network Address Translation (NAT)
between the public Internet and your Local Area Network (LAN).
•Connect an active RJ-45 LAN cable for the broadband service to the
LAN port on the rear of the codec.
•If there is an active connection on the LAN cable, the green LED
underneath the LAN port will illuminate and the orange LED will flash
steadily.
•By default, the Tieline codec is set to DHCP. Reprogram static IP
address settings on the codec by scrolling to the IP connection you wish
to connect with on the main codec LCD screen.
•When the square brackets [ ] surround the connection press SOFTKEY
3Wiz. Use the default settings of [Algorithm →Music←] > [ Audio
Bitrate →9600←] > [Local FEC Percent →Off←] > [Remote FEC
Percent →Off←] > [Jitter Buffer Type →Auto Jitter Adapt←] > [Auto
Jitter Priority →Best Compromise←] > [TCP Session Port →9002 or
9012←] > [Audio Port →9000 or 9010←] > [Ethernet Link →Auto←]
> [IP Setup →Static←] > [IP Address →Enter Number←] > [Subnet
Mask →255.255.255.0←] > [Default Gateway→Enter Number←] >
[Auto Reconnect →Disable←] > [RTP Configured →OK←]
•Please note: press the CLEAR button on the codec keypad to delete the
existing number and then enter a new static IP Address, Subnet Mask
and Default Gateway (check with your IT administrator if you are
unsure).
•Check the codec’s IP Address by selecting Menu > Unit Details > IP
Address. Please Note: Depending upon how your network is
configured, it may also be possible to simply connect your Tieline Codec
directly into your DSL/ADSL modem/router and receive a Public
address from the router. A public address typically looks like
203.35.196.135 and is out of the ranges: 10.0.0.1 – 10.255.255.255,
RJ-45 Connector
Go to Table of Contents

IP & 3GIP – A New Frontier in Broadcasting
Tieline Page 10
T E C H N O L O G Y
169.254.0.0 – 169.254.255.255, 172.16.0.0 – 172.31.255.255 and
192.168.0.0 – 192.168.255.255.
•Once you are set up in the studio you are now ready to receive an
incoming call from a remote codec over the Internet. Unless the remote
codec has a public IP address assigned to it and you know what the
number is, you will always have to dial the public IP address of the
studio from the field codec.
•Once the settings have been configured on both the field and studio
codecs follow the instruction titled “10 Simple Steps to Connect Tieline
Codecs” to Create a new connection.
1.4. IP Streaming Quick Start Field Unit Configuration
Normally, in the field you will only need to attach your Tieline codec to a LAN
with access to the Internet. You will not need to know the public IP address or
have to configure network address translation. Plug in the Tieline codec and
check that it has been assigned a private IP address. Then you should be able to
simply enter the static public IP Address of the studio codec and dial to connect.
1.4.1. Programming Field Codec Network Connectivity
•Connect an active RJ-45 LAN cable for a broadband service to the
LAN port on the rear of the codec.
•If there is an active connection on the LAN cable, the green LED
underneath the LAN port will illuminate and the orange LED will flash
steadily.
•By default, the Tieline codec is set to DHCP. In this mode a DHCP
server (if available) usually assigns a private IP Address to connected
devices automatically. Check to see if the codec has been allocated a
DHCP IP Address by selecting Menu > Unit Details > IP Address. They
are generally in the ranges: 10.0.0.1 – 10.255.255.255, 169.254.0.0 –
169.254.255.255, 172.16.0.0 – 172.31.255.255 and 192.168.0.0 –
192.168.255.255 and are assigned by network DHCP servers. Note: If
an address has not been assigned, contact the venue’s network
administrator about programming a static IP address. The procedure
for programming this is similar to programming a studio codec.
•If an IP address is visible then check settings on the codec by scrolling to
the IP connection you wish to connect with on the main LCD screen.
•When the square brackets [ ] surround the connection press SOFTKEY
3Wiz. Use the default settings of [Algorithm →Music←] > [ Audio
Bitrate →9600←] > [Local FEC Percent →Off←] > [Remote FEC
Percent →Off←] > [Jitter Buffer Type →Auto Jitter Adapt←] > [Auto
Jitter Priority →Best Compromise←] > [TCP Session Port →9002 or
9012←] > [Audio Port →9000 or 9010←] > [Ethernet Link →Auto←]
> [IP Setup →DHCP←] > [Auto Reconnect →Disable←] > [RTP
Configured →OK←]
•Double-check the codec’s IP Address by selecting Menu > Unit Details >
IP Address.

T E C H N O L O G Y
•Once the settings have been configured on both the field and studio
codecs follow the instruction titled “10 Simple Steps to Connect Tieline
Codecs” to create a new connection.
1.5. 10 Simple Steps to Connect Tieline Codecs
This section outlines the Quick Start procedure for connecting codecs using IP.
Unless the remote codec has a public IP address assigned to it and you know
what the number is, you will always have to dial the public IP address of the
studio from the field codec. I.e. always dial from the field codec to the studio
codec over the Internet.
Warning: If you connect over IP and use auto jitter buffer then both codecs
must have firmware v.1.6.xx installed.
Use the black rotary MENU SELECTOR (MS) to scroll through menus and press
it to select menu items. If more detailed connection information is required,
please see the ‘Quick Start’ section of each codec’s reference manual for more
information.
Step 1. Disconnect power from the codec before installing any module into it.
Step 2: Plug power into the codec and attach any POTS, ISDN or Ethernet
lines that are required.
Step 3: Turn on power to the codec and select Menu by pressing SOFTKEY
4. Then select [Load profile] to choose the type of connection to
connect with (i.e. default profiles or any Custom Profile). Select the
profile you want from the menu and press SOFTKEY 2 to load the
profile.
Step 4: Use the black rotary MS to scroll to the connection you are using, i.e.
[IP1 Enter#] etc, until it is surrounded by the square brackets [ ].
(Note: If “Unavailable” is displayed there is a connection issue that
needs investigating.)
Step 5: Plug your microphones and/or music sources into the codec and
adjust the input gain, phantom power (default is off) and other audio
settings by pressing SOFTKEY 1 Aud. (If you are not using a
microphone at the codec you are dialing from go to step 7).
Step 6: The default input level setting is Line Level. To adjust input gains
press SOFTKEY 1 with Aud displayed above it and scroll to and select
[Input Gains]. Select the input gain setting you require for each
individual input or select [All Inputs] to change all inputs
simultaneously. Press the CLEAR button on the keypad twice to
return to the main LCD screen. WARNING: Phantom power of 15
volts is always switched on for the TLR300B rack mount codec
analog microphone input.
Step 7: Scroll until the square brackets [ ] surround the connection you will be
dialing (e.g. IP1 Enter# ) and type the number/IP address for the

T E C H N O L O G Y
connection via the keypad. (Note: the “*” key on the codec keypad
inserts a period into an IP address).
Step 8: Press the ENTER DIAL button on the codec to dial and connect. To
negotiate higher bit-rates press “F2” then “3”; for lower bit-rates press
“F2” then “9”.
Step 9: Repeat steps 7-8 if dialing a second connection.
Step 10: On an i-Mix G3 press the yellow CUE button to send audio over the
communications channel. If you are using a field unit COMMANDER
G3 codec, once both channels are connected hold down the MS for 2
seconds and a secondary activation menu will appear along the
bottom of the screen. You will see CUE1 and CUE2 above HOTKEYS
2and 3. (Please note that rack unit codecs and the TLG3 GUI rack
mount codec control software have dedicated CUE buttons so you will
not need to do this). Pressing the CUE key on either of the 2
microphone inputs will route audio from these inputs to the off-air bi-
directional communications channel only. Audio being sent will be
heard in the right side of both headphone outputs. Communications
audio will be displayed on PPM 2. To return to the main menu hold
down the MS for 2 seconds, or it will automatically return to the main
menu after two minutes. For more information on the i-Mix G3
phone coupler, please see the codec reference manual.
If you are unable to achieve a connection using these instructions, please refer to
the detailed information relating to IP and 3G/IP connections that follows in this
reference manual. Alternatively, contact your IT Network Administrator for
assistance configuring your network or contact Tieline on [email protected]
for support.

1.6. Quick Start Procedure for 3G IP Connections (version 1.6.xx
firmware or higher)
Connecting your codec over 3G is very similar in principle to connecting over IP.
The only difference is that you are wirelessly connecting to your ISP instead of
connecting via a LAN. Connect to your ISP/cell-phone provider and then use
the Quick Start connection procedure for your preferred connection profile (i.e.
mono, stereo, mono/IFB and dual mono program) over IP.
Very Important Warning:
Tieline CDMA EV-DO 3G modules don’t use SIM cards and need to be activated
and provisioned in order to connect to cell-phone networks in the U.S.A. Use the
procedure outlined in this manual to program your module before use over these
networks.
Important Note:
As a factory default, GSM/3G settings are programmed for AUTODETECT. If
you plug a 3G or USB module (with a 3G phone connected) into your codec it
will program it to operate in 3GIP mode by default.
If you use a GSM module or plug a GSM cell-phone into the serial port of your
codec it will program it to operate in GSM CSD mode by default.
If you wish to use a 3G phone in GSM mode, you will need to change the
Wireless Network setting in the GSM/3G Wizard to either GSM CSD or GSM
HSCSD - depending on the connection you wish to use.
1. Insert a Tieline 3G module (with a SIM card installed for UMTS/HSDPA
networks or provisioned & activated for EV-DO networks) into your codec
and then power up the codec.
2. Scroll to the 3GIP1 connection with the codec MENU SELECTOR and press
SOFTKEY 3 Wiz and then select SOFTKEY 4 OK. Next select [Wireless
Network →3G/UMTS IP←] > [3G/UMTS IP Network →select your
network←] > [Auto Reconnect →Disable←]. Select SOFTKEY 4 OK to
complete configuration and return to the main LCD connection screen.
3. If 3GIP1> Prs Entr is displayed, press ENTER/DIAL to connect to your 3G
network. If 3GIP1> Enter # is displayed, dial the SIM card cell-phone number
using the codec keypad and then press ENTER/DIAL to connect to your 3G
network. This is because some cell-phone networks require you to dial this
number to connect.
4. Once you have connected the codec connection will display 3GIP1> Cntd
Goto IP
5. Now scroll to IP1 on the main codec LCD screen and connect using the
Quick Start IP profile you have selected, i.e. mono, stereo, mono/IFB or dual
mono. Type the IP address of the codec you are dialing. (Note: Use the * or #
button on the codec keypad to enter the periods (.) in the IP address).
6. Press the ENTER DIAL button on the remote codec’s grey keypad to begin
dialing. In many situations it is only possible to dial from the remote codec to

the local codec with IP connections because only the studio codec is using a
public IP address.
7. Try to maintain a link quality (LQ) reading for your connection of between
70% and 100%.To negotiate higher bit-rates press “F2” then “3”; for lower
bit-rates press “F2” then “9”. For best performance, the dialing codec should
be used to renegotiate connection bitrates up and down. If you hear audio
drop-outs the current bit rate cannot be sustained and should be renegotiated
down. To disconnect, hang up your IP connection and then hang up the 3G
connection.
8. To disconnect, hang up your IP connection and then hang up the 3G
connection.
9. To change other 3GIP settings select SOFTKEY 4 OK and scroll to
[Configuration] > [GSM/3G Setup] > [3G Module].
Note on Cell-phone Use with Tieline USB Modules:
Turn on your 3G cell-phone and wait 30 seconds before you connect the phone
to the USB module via its USB cable (this cable should be available from your
cell-phone manufacturer). Within 30 seconds a 3GIP1 connection should appear
on the main codec connection LCD screen.
Cell-Phone Warnings
If you are unsure about the compatibility of a particular cell-phone, please see the
‘How to connect over 3G with a USB Module & Cell-phone’ section of this
manual, or contact Tieline at [email protected] for more information.
1.7. What to do if a Network is Unavailable in the Codec
An expansive list of cell-phone networks covering 52 countries is currently
programmed into Tieline codecs. Due to the number of new cell-phone networks
coming on stream all the time, it is possible that a network you wish to connect to
may not be listed in the codec.
In this scenario it is still possible to program a ‘custom access point’ into your
codec for your preferred network. To do this you will need a PC with ToolBox
software installed in order to program the access point and then create a .cdc file
to load onto the codec.
Before programming the access point some information is required from the
network provider you are connecting to. These include:
1. An access point address;
2. A dial string;
3. An account number; and
4. A password.
Once you have been supplied with these details open ToolBox and go to the
GSM LL/GSM/USB-3G tab and complete the following:
Go to Table of Contents

IP & 3GIP – A New Frontier in Broadcasting
Tieline Page 15
T E C H N O L O G Y
1. Check the Use Custom Access Point check-box in the GSM 3G/UMTS IP
Network menu;
2. Enter the Access Point address;
3. Enter the Dial String ;
4. Enter the Account details;
5. Enter the Password for the network;
6. Enter a User-Defined Label to identify the custom access point.
Save the settings into a profile, load the configuration file onto the codec and you
are ready to connect to the network. The network you have programmed should
appear in the 3G/UMTS IP Network codec menu at the bottom of the available
networks.
Custom Network Tip:
If you find that there are multiple networks that you wish to connect to that are
not listed in the 3G/UMTS IP Network codec menu, simply create a new profile
for each network and enter the relevant ‘custom access point’ details into each
new profile. Save these profiles together in a *.cdc file and load this file onto the
codec you will be using over these networks.
1.7.1. Tell us about a New Network
Tieline will add new networks to each release of codec software. Email
[email protected] with the name of any network you want added along
with:
1. The access point address;
2. The dial string;
3. The account number; and
4. The password.

1.9. Checklist for Obtaining High Quality IP Connections
The following 10 tips are provided to help obtain the best possible IP connection
between two codecs, without paying for QOS (Quality of Service).
1) Always use the best quality Internet Service Provider (ISP). Tier 1 service
providers are best as their infrastructure actually makes up the Internet
‘backbone’. Wikipedia lists the major service providers that make up the
Internet backbone at: http://en.wikipedia.org/wiki/Internet_backbone. In
Australia Telstra is equivalent to one of these service providers.
2) You will get the best quality connection if both the local (studio) and remote
codecs use the same Internet service provider. This can substantially increase
reliability, audio bandwidth and reduce audio delay. Using the same service
provider nationally can give better results than using different local service
providers. This is especially true if one of the service providers is a cheap,
low-end domestic service provider, which buys its bandwidth from other ISPs.
Second and third tier providers sublease bandwidth from first tier providers
and can result in connection reliability issues due to multiple switch hops. We
also highly recommend using First Tier ISPs if connecting two codecs in
different countries.
3) Sign up for a business plan that provides better performance than domestic
or residential plans. Business plans typically have a fixed data limit per month
with an additional cost for data beyond that limit. In addition, Service Level
Agreements (SLA) will often provide better support and response times in the
event of a connection failure. Domestic plans are often speed-limited or
“shaped” when usage exceeds a predefined limit. These plans are cheap but
they are dangerous for streaming broadcast audio.
4) Ensure that the speed of the connection for both codecs is adequate for the
job. The minimum upload speed recommended is 256 kbps for a studio
codec and 64 kbps for a field unit connection.
5) Use good quality equipment to connect your codecs to the Internet. (Tieline
successfully uses Cisco®1switching and routing equipment.):
a. If you are using a DSL or ADSL connection make sure you purchase
a high quality modem that can easily meet your speed requirements.
This is especially important if you are over 4 kms from an exchange.
b. If you have multiple codecs connected to a local area network (LAN)
please ensure that your network infrastructure is designed for media
streaming and not domestic usage. Tieline has tested several cheap 8-
port switches that lose more packets between local computers than an
international IP connection between Australia and the USA!
Please Note: You should be able to stream audio between two codecs on
your LAN and get ‘link quality’ readings of L99R99. If you see anything less
than this then you should get a network engineer to investigate the issue.

c. If using a wireless connection ensure that the antenna signal strength
received is strong. The type of antenna used and the amount of
output gain also affects connection quality.
d. If you are using a 3G phone please make sure the battery is fully
charged and that you are close to a cell-phone base station.
6) Once your Internet connection is installed at the studio check that the
connection performance is approximately what you ordered and are paying
for. A connection can perform below advertised bit rates if:
a. There is an error in ISP configuration;
b. There is an error in modem configuration;
c. There is a poor quality line between the studio and the exchange;
d. There are too may phones or faxes connected to the phone line; or
e. Line filters have been connected incorrectly.
You can test the Internet connection speed by connecting a PC to the
Internet and using http://www.speedtest.net/index.php. If the bandwidth
detected is low then something is wrong. Get it fixed before going live!
7) Use a dedicated DSL/ADSL line for your codecs. Do not share a link with
PCs or company networks. The only exception to this rule is if an
organisation has network equipment and engineers that can implement and
manage quality of service (QOS) on its network.
8) Use UDP as the preferred audio transport protocol. TCP generally results in
lower bitrates and random drop-outs of audio over the Internet. Only use
TCP if UDP is blocked by firewalls and you are unable to connect.
9) When using UDP ensure the total bit rate (audio bit rate plus header bit rate)
is no more than 80% of the ISP connection rate. IP headers require around
20 kbps in addition to the audio bit rate. For example, with a 64 kbps
connection the audio bit rate should be (64-20) x 0.8 = 31.2 kbps or lower.
For TCP we suggest a limit of 50% or less.
10) Wireless IP connections can easily become congested and result in packet
loss and audio drop-outs. It is very difficult to guarantee connection quality
when there is no way of knowing how many people are sharing the same
wireless connection. Examples of wireless connections include:
a. WiFi connections within your LAN (These are unmanaged
connections and should not be used to distribute audio when setting
up IP connections);
b. GSM CSD and HSCSD connections; and
c. EV-DO, 3G UMTS or HSDPA phone connections.
Note: Be careful when using cell-phone connections at special events where
thousands of people have mobile phones. This can result in poor quality
connections and audio drop-outs if cell-phone base stations are overloaded.

Complete the following check list and aim for a score of at least 8 out of 10
before going live.
Number Check Result
1 Using a reputable Tier1 ISP that’s part of Internet backbone.
2 The same ISP is being used for both codec connections.
3 The ISP Plan is a Business Plan or equivalent.
4 The ISP connection speed is adequate (256 kbps or higher).
5 Equipment is high quality and suitable for media streaming.
6 The ISP connection speed has been tested and is suitable.
7 The ISP connection is not shared with PCs or other devices.
8 UDP is being used as the audio transport protocol.
9 Only up to 80% of ISP connection bandwidth is being used.
10 There are no wireless connections being used.
1.10. How to Order the Right Plan for your 3G Service:
There are many data services offered by Telcos. At the time of writing this,
HSDPA and EV-DO Rev A offer the highest bit rates and therefore the best
opportunity for delivering stable high quality audio. Try to use these services from
a reliable provider in your region.
One of the most expensive mistakes you can make is borrowing a 3G SIM card
for a broadcast that will last a couple of hours. It is likely that this type of 3G plan
is optimized for voice and not IP data. Don’t find out the hard way – it could be
an expensive mistake! We recommend you purchase a plan that includes
unlimited data for a fixed price per month. Then you can broadcast for as long as
you need for a fixed price per month.
If this type of plan is not available, estimate the number of remote broadcast
minutes/hours you need per month and buy a plan that bundles large blocks of
data for one price. Some telcos also offer ‘timed’ or ‘minutes’ plans, which offer
unlimited data for fixed amounts of time.
Warning: Some 3G network providers prohibit streaming multimedia of any
kind on certain accounts. Also, some plans charge very high rates for data, or
may ‘throttle’ or ‘shape’ your available bandwidth after a certain amount of data
has been transferred. Check with your telco before subscribing to a plan.

1.11. Troubleshooting Network Device Settings
1.11.1. Port Settings
For your Tieline Codec to communicate over the public Internet an IP
Address alone is not sufficient. The Internet Protocol pre-defines TCP and
UDP protocol port numbers for specific functions.
Tieline codecs use TCP ports for setting up the communication session and
UDP ports for streaming audio. While TCP ports are generally open, UDP
ports are generally blocked by network devices which contain firewalls and
will stop you delivering your audio. You need to configure your firewall to
allow TCP and UDP protocols to pass through on the specific ports listed in
the table below.
Default Tieline Ports
Application Session Port Audio Port
IP1 TCP 9002 UDP 9000
IP2 TCP 9012 UDP 9010
Tieline ToolBox &
TLG3GUI UDP 5550
SIP UDP 5060 UDP 5004
Table 2: Default Tieline Port Allocations
Figure 1 illustrates the firewall port settings on a sample ADSL Internet
router. Consult your Network Administrator if you are unsure how to do this.
