Chapter 3 TED8620B+ Internet Connection
3.1 RFC Static IP Mode to Internet
3.1.1 Introduction
This mode is for using fixed IP mode to connect to Internet
through ADSL2+, you can set the IP address of your NIC according to
the information provided by your ISP or broadband access services
provider. And then you can use the dial-up software (PPPoE dial-up
software) to connect to the Internet.
3.1.2 Setting of IP Address (Take example under Windows 2000)
First we can see there is one icon called “My Network Place” on
the desktop screen, we can move our mouse to it and then click the
right key and then choose “Properties”, and we can open the window
of “Network Connections”, as follows:

TED8620B+ ADSL2+ Modem User’s manual
In the figure above, we can see the icon of LAN (If you have more
than one NIC, then it may be LANX, X is related to the number of NIC
that you have). We can move our mouse to LAN and click the right key
and choose “Properties”, then we can open the window of LAN
properties, as the figure below:
Then we should choose the Internet Protocol (TCP/IP) and click
“Properties”, as the figure below:

TED8620B+ ADSL2+ Modem User’s manual
If the information offered by the ISP is as follows, configuration is as
the figure above:
IP Address: 192.168.0.40
Subnet Mask: 255.255.255.0
Gateway: 192.168.0.100
Preferred DNS Server: 202.96.128.86
Alternate DNS Server: 202.96.128.166

3.2 RFC1483 Dynamic IP Access Mode
3.2.1 PPPoE Dial-Up Introduction
This mode is suitable of most users, that is to say, in the normal
ADSL2+ access, you don’t need any other configuration, you just need
to install a PPPoE dial-up software and then you can connect to the
Internet.
PPPoE dial-up mode is based on RFC1483 Bridge, because this
equipment is integrated with more than one VPI/VCI rules, we can dial
up directly. In the following, we take WinPoET for example.
3.2.2 Installation of WinPoET Dial-UP Software
Installation of WinPoET dial-up software is easy and convenient, it can
support many different kinds of operation system. Before installation,
you just need to obtain the WinPoET dial-up software through your
ISP or download it from Internet.
After obtaining the installation software of WinPoET v4.00, which is
WINPOET4.EXE, please double click it to run it, the following
interface will appear in the screen, please press button “YES” to
continue installation.

window of this software, and press “Connect” and then you will be
able to dial up. After identification of user’s name and password, you
will be able to connect to the Internet.
Note: Please consult your ISP for the Internet information before
installing this ADSL2+ modem.

4. FAQ
4.1 Does ADSL2+ support share of Internet Access to
Internet in LAN?
Answer: Yes. And there are three methods to do this.
a. Choose the Internet share software which support ADSL2+, and
please also pay attention to the sequence of installing the software.
You should first install the PPPoE software and then the Internet
share software like Sygate. The integrated ICS share of of Windows
2000 and Windows 98 second version both support ADSL2+. Or
you can set the host which is directly connect to ADSL2+ as Proxy
Server., and then the clients in LAN will have access to the external
sources through this Proxy Server. Advantage of this is that you just
need to apply for one ADSL2+ account or require only one IP
address. Client in LAN can use the reserved IP Address.
b. Use the method of special line. Apply IP addresses for all computers
in the LAN. Advantages of this is that you don’t need to configure
an extra Proxy Gateway, disadvantages is that due to the current
technical shortage, the ISP can offer limited IP address to LAN.
c. Connect a Router behind the ADSL2+ modem, apply a series of IP
addresses for computers in LAN from the ISP. When these IP
addresses are routed by the ISP, the computer will be able to connect

TED8620B+ ADSL2+ Modem User’s manual
16
to the Internet. Advantages of this method is that the number of
computer is not limited ,but you need to equip an extra computer.
4.2 How to set and obtain dynamic IP for LAN users?
Answer: Take Win 98 for example: Open the ”Change a setting”, find
Network, double click and open Network Properties, select
TCP/IP protocol, open Properties of TCP/IP protocol, select
the IP address obtainment mode as “Automatic Obtainment
of IP address”, press enter, and then reset the computer. Then
it will be ok.
4.3 I am now using ADSL service, can I use the ADSL2+
modem to have access to the Internet?
Answer: Yes. Currently, ADSL2+ is compliant with all ADSL
service. What’s more, you would save the money when the
ISP upgrades ADSL to ADSL2+. The price difference
between ADSL2+ and ADSL is very slim. So, it is
reasonable to choose ADSL2+.
