Preface
Thank you for placing your trust in this devolo product.
By purchasing the MicroLink ISDN Router or MicroLink dLAN ISDN Router,
you have chosen an ISDN router that innovatively combines the functions and
advantages of an ISDN modem, a switch, a router and a firewall all in a single
device. This combination makes it the optimal, user-friendly network and
Internet access solution for home network solutions and small-office and
home-office (SOHO) environments.
The ISDN modem provides satisfyingly fast Internet access:
With transmission speeds of up to 128 kbps, long waits when down-
loading files, loading Web pages or playing online games are a thing
of the past.
An installation wizard helps you get connected to the Internet quickly.
Access settings for common ISPs are already preconfigured.
It serves as an optimal combination of Internet-access device and net-
work switch:
The router simplifies the installation of Internet access significantly,
as no special drivers are required for the connected individual com-
puters. The access protocol has been implemented in the router
itself.
The router functionality lets multiple users access the Internet at the
same time. The firewall function provides protection from hacker
attacks. DHCP automates the TCP/IP configuration of the connected
computers. The router can be configured conveniently using a Web
browser.
The integrated switch is the foundation for small networks. Up to four
computers can be connected simultaneously. Each of the four ports
can also be used as an uplink port to connect additional routers,
switches or hubs.
A HomePlug adapter allows access to the router throughout the building
without having to lay new lines. Instead of network cables, household
power lines are used to transfer data.
Combine your MicroLink ISDN Router together with a devolo Home-
Plug adapter to connect to other network devices via the household
power cables.

MicroLink dLAN
ISDN Router only
The HomePlug adapter is already built into your MicroLink dLAN
ISDN Router. The router is automatically networked to all other
HomePlug adapters simply by connecting it to the power supply grid
of the building.
DESpro encryption provides the highest degree of interception protec-
tion during data transmission over the power supply grid.

1 Introduction
1.1 What does the MicroLink (dLAN) ISDN Router
have to offer?
The following is an outline of the principal features of the device giving you
a quick overview of its capabilities.
Simple installation
Connect the computers in the LAN (Ethernet) to the MicroLink (dLAN)
ISDN Router.
Connect the MicroLink (dLAN) ISDN Router to the ISDN connection.
Connect the MicroLink (dLAN) ISDN Router to the power supply grid.
Configure Internet access
That's it!
Versatile networking
Because of the built-in 4-port switch, the PCs connected to the MicroLink
(dLAN) ISDN Router form an internal network with transfer rates of up to
100 Mbps.
MicroLink dLAN
ISDN Router only
The MicroLink dLAN ISDN Router lets you choose how you would like to con-
nect your PCs to the Internet— you can connect them using either the power
supply grid or network cables.
Thanks to the built-in HomePlug technology, the network can be expanded
through household power cables without the need to lay new lines. Each PC
simply needs a MicroLink dLAN connected to an electrical outlet. With dLAN,
you can connect to the Internet, exchange data, share printers or play exciting
multiplayer games from any room of your house. Simply connect the router to
the rest of the dLAN network via the power cable. The four Ethernet ports
remain available for connecting other network devices.
1.2 What exactly is dLAN?
There is now a new alternative to the well-known wired LAN and Wireless
LAN network technologies: dLAN (direct LAN, i.e. directly networked). dLAN
is networking using the electric wiring already installed in the building.

Cost factor and transmission quality
dLAN is an especially easy-to-use networking technology. You don't need to
lay cables and you can connect to the network at every power point.
The dLAN standard modulates and demodulates additional frequencies on
the power lines. Modulation and demodulation is a well-known and proven
method of data transmission, which has been in use in other applications for
a number of years. Now it is used to set up Internet and network accesses.
Depending on the attenuation factor, dLAN is capable of covering distances
of at least 200 meters.
With a maximum data transmission rate of 14 Mbps and symmetrical upload
and download, the dLAN standard is equivalent to classical Ethernet net-
working solutions and is faster than the wireless standard 802.11b. Depend-
ing on the line quality, bandwidths of 6 to 8 Mbps are possible in practice—
quite sufficient for extending the Internet connection.
Data security and radiation
For security reasons, DESpro encryption is used, which guarantees secure
data transfer within the network. In addition, the power meter in the building
can act as a physical barrier against unwanted access from outside.
dLAN devices from devolo meet the stringent EU industrial standards and
comply with the current standards for electromagnetic radiation. Its radiation
level is actually well below that of Wireless LAN technologies.

2.2 Connecting the MicroLink (dLAN) ISDN Router
Preconditions
Your MicroLink (dLAN) ISDN Router requires a computer running an operating
system with TCP/IP support (e.g. Windows 98, Windows Me, Windows 2000,
Windows XP, MAC OS X, Linux) connected to the MicroLink (dLAN) ISDN
Router via LAN (Ethernet).
To connect a computer to the integrated switch via LAN, use a network cable
with RJ45 plugs, also known as a patch cable. The computer must have a free
LAN port (RJ45).
Connection
햲Connect the MicroLink (dLAN) ISDN Router to an AC outlet using the AC
adapter. Turn on the power with the switch on the back. The green
'Power' LED on the front panel will light up.
햳Connect the ISDN cable first to the 'ISDN' socket on your router and then
to the ISDN connection.
햴Next, use network cables to connect up to four computers to a router's
RJ45 socket (LAN port) respectively and start the connected computers.
The associated 'Link/Act' control lamps light up.

It is important to always start the router before the computers so that the
computers can receive their TCP/IP configuration from the router's DHCP
server while booting.
As each of the RJ45 sockets also functions as an uplink port, you may connect
either a computer or an additional switch (hub) to any of the four ports to link
more than four computers. Thanks to Auto MDI/X, you can use either cross-
over or normal cables. An LED labeled 'Link/Act' will be lit on the front panel
for every computer or every network device which is connected and powered
up.

3 Router configuration
This chapter will explain how to set up Internet access and how to take
advantage of additional functions and settings of your router with advanced
configuration.
If you intend to use a computer connected via dLAN to configure the router,
you must set up the dLAN network first. For more information, please see
“Configuring the dLAN network with the MicroLink dLAN Configuration Wiz-
ard” on page 29.
The configuration of the MicroLink (dLAN) ISDN Router takes place in the fol-
lowing stages:
Check the network settings of the computer on the local network and
modify them as necessary
Set up Internet access
Configure additional router functions
For configuring the network and setting up Internet access, we recommend
using the setup wizard, which will help you configure the necessary settings
(“Setting up Internet access using the setup wizard ” on page 15). Alterna-
tively, you may also set up Internet access using browser-based configuration
(“Setting up Internet access manually” on page 16). The MicroLink (dLAN)
ISDN Router is already optimally pre-configured for simple Internet access.
The additional functions of the router must be set up manually using the
browser-based configuration (“Advanced configuration” on page 18).
If you have switched the router's power off and back on, or reset the router
using the 'Factory Default' button, you must then also restart all of the con-
nected computers to update the network settings.
3.1 Set up Internet access
3.1.1 Setting up Internet access using the setup wizard
If you are using a computer with a Windows operating system to configure
the router, you have the option of using the setup wizard.
햲Put the enclosed devolo product CD in your CD-ROM drive. The 'devolo
MicroLink (dLAN) ISDN Router' setup application will start automatically.

Router configuration |
|devolo MicroLink ISDN Router & MicroLink dLAN ISDN Router |
16
EN
If the Setup software does not start automatically, run the file ’autorun.exe’
in the root folder of the product CD.
햳Select 'Install MicroLink (dLAN) ISDN Router software'.
햴The wizard will now install the selected devolo software on your com-
puter. When the installation is complete, the router configuration wizard
will automatically start. During this process, the wizard first checks the
computer's network settings and modifies them as necessary. Then the
wizard helps you set up Internet access for the router.
햵Finally, the wizard will contact the devolo website to ensure that the
Internet access is working. If the Internet connection is working correctly,
configure all other connected computers. Insert the devolo product CD in
the computers to be configured and install 'MicroLink (dLAN) ISDN Router
installation' as a minimum. The wizard will then check the settings of the
network and correct them as necessary, and will skip setting up Internet
access again if so requested.
Note that modern operating system features (like the Windows Update fea-
ture) and various programs such as e-mail and file-sharing clients can be con-
figured to connect to the Internet automatically, which can cause charges
from your service provider.
For this reason, once you are done setting up the router, pay attention to the
router to see how and when it connects to and disconnects from the Internet.
The cost control setting is pre-configured to a maximum of seven online hours
per week (see “Cost control” on page 21).
3.1.2 Setting up Internet access manually
To configure Internet access for your MicroLink (dLAN) ISDN Router, you will
need a computer that is connected to the router with a network cable and is
installed with an Internet browser.
The computer you are using to configure the MicroLink (dLAN) ISDN Router
must be set up to receive network settings automatically. For further informa-
tion, please see the documentation of your operating system.
햲Open your browser and enter the URL 'http://192.168.0.251'.
햳Click 'Set up Internet connection', to start the corresponding wizard.

|Router configuration 17
|devolo MicroLink ISDN Router & MicroLink dLAN ISDN Router |

햴A list of countries appears. For each country, selected Internet service
providers have been pre-configured. Select your location from the list and
click 'Next'.
햵Choose your Internet provider from the list and confirm your choice by
clicking 'Next'.
If you are using an unlisted provider, select the entry 'other provider' and set
up the connection manually.
햶Enter the call number for your Internet provider. If your router is con-
nected to a branch exchange, enter the number you have to dial to access
an outside line in the 'Number to access an outside line' field (such as
"9"). Then click 'Next'.
햷Some Internet service providers require you to enter additional access
data (such as a user name and password). This is data that you receive
from your Internet service provider. Enter the data accordingly and then
click 'Next'.
햸To confirm and save the new data to your router, click 'Finish'.
햹Finally, check whether the Internet connection works by entering a URL
such as www.devolo.com in your Web browser. Once your Internet
access is working correctly, set the remaining connected computers to
automatically receive network settings. For further information, please
see the documentation of your operating system.
3.1.3 Checking your Internet connection
After you have configured your Internet connection correctly, the router can
establish a connection to the Internet automatically for all computers on the

network. Data for checking the Internet connection is provided on the entry
page of the router configuration utility (http://192.168.0.251).
From this site, you can view whether you are currently connected to the Inter-
net in the section called 'Status'. The advanced status includes, in addition to
ISDN connection data, the current IP and DNS addresses assigned to the
router from your Internet service provider and the duration of the current
Internet connection. The 'Cost control' section indicates the valid time limits
and the amount of minutes used so far (see “Cost control” on page 21).
To update and view the latest data, simply click the refresh button in your
browser.
If you want to disable access to the Internet from the computers on your net-
work completely, you can disable the Internet connection on the entry page
of the router configuration utility. This does not affect the router settings. All
access data for the Internet connection remain intact for later use. To enable
the Internet connection again, simply click the 'Activate Internet connection'
button on the entry page of the router configuration utility.
3.2 Advanced configuration
In this chapter, we will be guiding you through the advanced configuration of
the MicroLink (dLAN) ISDN Router, explaining its functions and settings.

3.2.1 Start Advanced configuration
햲Open your browser and enter the URL 'http://192.168.0.251'.
햳Select 'Management (for advanced users)'.
햴Click the 'Display expert configuration' link.
Keep in mind that the settings you have configured only take effect if you con-
firm them by clicking 'Save'.
3.2.2 General
Configuration access
Specify the configuration password here.
Select a password to prevent unauthorized access to the configuration of
your router. Enter it into both fields. Should you ever forget your password,
you will need to press the 'Factory Default' button. However, this will also
delete all of your configuration data. You will then need to set up the router
again. Save your new password by clicking 'Save'.
Please note that changing the configuration password will block the setup
wizard. Use of the setup wizard is disabled if a configuration password is set
up.
ISDN connection
For 'Own phone number (MSN)', specify the call number of your ISDN connec-
tion (without area code). If your router is connected to a branch exchange,
specify the number you have to dial to access an outside line in the 'Number
to access an outside line' field (such as "9").

3.2.3 Internet connection
Access data
Here you can view and modify the access data for your Internet service pro-
vider.
Connection control
Your router can connect automatically to the Internet when an application on
a computer on your network (such as an Internet browser or e-mail program)
requests access to the Internet. If you want to disable this feature, select 'No'
for the 'Set up Internet connection automatically' option.
The 'Idle time, after which the connection is disconnected' option indicates
how many seconds the connection should be kept even though none of the
computers on the network has sent any data to the Internet. To keep the con-
nection from being interrupted too frequently, which requires the router to
reestablish the connection when needed, do not enter this value too low. We
recommend setting this value between 60 and 180 seconds initially, and
adjusting later as necessary.
Note that modern operating system features (like the Windows Update fea-
ture) and various programs such as e-mail and file-sharing clients can be con-
